You need to use the SchemaAttributes property. For standard attributes they must be named according to the Open ID Connect specification -http://openid.net/specs/openid-connect-core-1_0.html#StandardClaimshttp://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-settings-attributes.htmlBy doing this they will map appropriately and you can set other properties on the property such as Required. It appears the docs need to be updated to make this more clear.http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cognito-userpool-schemaattribute.html

I am trying to code my cognito userpools as cloudformation templates. I am running into one open question however: how to define standard attributes? Will Cognito know thatbirthdateinSchemais meant to be the standard birthdate - and validate it as such? How is the attributeSchemadefined in the cloudformation template mapped to the standard, non-custom attributes likeemail,birthdate, ...?More details: AWS Cognito separates between standard attributes and custom attributes. This separation is amongst other things important because standard attributes are validated for their format:emailandbirthdatefor example accept only an AWS defined, specific format.Thus my question: how does AWS Cognito map the cloudformationSchemadefined attributes to standard AWS Cognito attributes? Does it at all, and if so by identity of the attribute name?Also see:AWS Cognito Cloudformation SchemaExample created by someone:Cloudformation example

I'm deploying a rails application to AWS. One of the gem's had a dependency and needs certain files installed on the server beforebundle installis run during deployment. In my.ebextensionsfile I have the following01-oracle_sdk:

04-container_commands:
00_oracle_dir:
command: "export LD_LIBRARY_PATH=/usr/lib/instantclient_12_1"From what I can tell, none of this is getting run pre-deploy. It fails when it tries to install the gem because that directory is not there. When I SSH into the instance,LD_LIBRARY_PATHis not set and none of the zipfiles were downloaded and unzipped by thesourcecommand.1) Is my syntax in correct 2) How do I get these commands to execute PRE deploy/bundle install?

Getting a perfect setup for a SPA or static page on Cloudfront is not trivial. In short, you will need to use (at least) an origin request lambda function setting for your CF distro. You need to handle a few edge cases like:hashesredirects to urls with trailing slashes (that you mentioned)forwarding of query parameters when redirectingFor a quick starting function you can check this articlehttps://tinyendian.com/articles/better-origin-response-function-for-cloudfront-hosted-static-pagesexplaining the actual code that you can copy from herehttps://gist.github.com/karolmajta/6aad229b415be43f5e0ec519b144c26eOf course it is likely that as your app changes, you will need to modify this snippet here and there to match your needs.

I have a static SPA page that is using S3 as it's origin with CloudFront. If I visit www.domain.com/page, I will get the CloudFront path prefixedbucket-directory/prod/page/which is expected.Is it possible to capture the path in AWS Lambda and append the trailing slash to a request, so it becomes, www.domain.com/page > [Lambda] > www.domain.com/page/I've been looking and trying the following resources to little avail:http://blog.rowanudell.com/redirects-in-serverless/http://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-create-api-as-simple-proxy-for-lambda.html

I am trying to figure out a way to get a users access key age through an aws lambda function using Python 3.6 and Boto 3. My issue is that I can't seem to find the right api call to use if any exists for this purpose. The two closest that I can seem to find arelist_access_keyswhich I can use to find the creation date of the key. Andget_access_key_last_usedwhich can give me the day the key was last used. However neither or others I can seem to find give simply the access key age like is shown in the AWS IAM console users view. Does a way exist to get simply the Access key age?

Here is what we ended up doing:Origin EC2 only allows HTTP (port 80)ELB only allows HTTPS (port 443) and targets the EC2 via HTTP (port 80)EC2 Security Group restricts HTTP access to the ELB's security groupCreated Route53 DNS entry for origin-blabla.example.com as an alias to the ELBCloudFront distribution redirects HTTP -> HTTPSCloudFront has origin-blabla.example.com as its originCloudFront origin has custom HTTP headerBoth CloudFront and ELB have a *.example.com TLS Certificate (I also could have used separate certs for specific domain names)URL Rewrite blocks/redirects all requests that don't have one of the following: a) the above-mentioned custom HTTP header or b) UserAgent that matches ^ELB-HealthChecker$So now all requests come to CloudFront via HTTPS (if they come as HTTP they are redirected to HTTPS), which connects to ELB via HTTPS, which in turn gets the data from EC2 via HTTP. This cannot be circumvented (unless someone is desperate enough to guess the origin DNS and brute force the custom HTTP header and add it to their browser request - and I'm not sure what they're really gaining by that) so we can rest assured that a) all requests are secure, b) there is only one domain name that can be used to access our system, and c) we don't have to worry about certificates on the server.
|
Our application is currently running on EC2 instances, requiring HTTPS (and redirecting HTTP to HTTPS). We are now considering serving all requests via CloudFront and enforcing HTTPS through CloudFront. Our thought is that once we do that we would then block HTTP/HTTPS requests not coming from CloudFront and relax the HTTPS requirement. This way all requests to CloudFront would be via HTTPS, but CloudFront would retrieve the data from the EC2 origin via HTTP. This way we would a) reduce some server overhead since the server doesn't have to do the TLS encryption and b) eliminate the need to manage certificates for the EC2 instances.Are there any security concerns with this or other reasons not to do this?

Couldn't answer as much in the comments so I'll try here.The architecture you linked to is pretty common. The two biggest downfalls are that you're going to billed for Lambda usage even if there is nothing to do and your data may be delayed by the amount of the polling interval which is a minimum of 1 minute. Neither of these things may matter in your problem though.SQS could be used as a temporary store for data in the event of a DynamoDB failure. But what exactly are you going to do if it fails? What if SQS fails and loses your messages? What if Lambda fails and never runs your code? DynamoDB is a hosted service just like SQS and Lambda - Amazon is going to work very hard to keep it running just like their other services. Trying to architect around every possible failure scenario will mean you never deliver code. I'd focus on the simplest architecture you can and put some trust in the services you're paying for.
|
I am building one service which would use the data that would come from another source(service). So, I am thinking to use the following pipeline:-Other service ----> SNS Topic ----> SQS ----> AWS Lambda ----> Dynamo DbSo, what above flow says is Another service will push data to SNS Topic to which an SQS would be a subscriber. Now AWS Lambda will have a trigger on this SQS which would listen to the messages in SQS and push it to Dynamo Db. Although it looks okay to do this. But now I am thinking if I really need SQS or not. Can I avoid using it? Instead of using SQS, AWS Lambda directly has a trigger on SNS. I am just thinking of one case if I don't use AWS SQS. How will it handle the scenario if AWS Dynamo DB fails? I think with only SNS, I would lose some messages during the time, my Dynamo Db is in failed state but if I have SQS, then those messages would be stored in SQS queue.Please let me know if my understanding is correct.Thanks a lot for your help.

I would recommend using Serverless Framework to improve developer productivity. Few of the practices we followKeep all the infrastructure changes in Serverless Framework generated CloudFormation stack template.Create different API Gateway stages for each developer.Utilize Serverless Plugins. E.g Serverless Offline, Severless DynamoDB Local & etc.Use a NodeJS proxy, if you plan to setup hybrid development environment e.g Use Serverless Offline plugin emulating API Gateway and Lambda localy, S3 with Cognito in AWS.Use a task runner like Gulp to automate starting web servers, deployment & etc.Use environmental variables to store environment specifics.Apart from this, its better to use a seperated AWS account for production. You can configure AWS organizations to simplify managing multiple accounts.

We are a team of 5 developers and need some guidance on the best way to develop on AWS specifically using AWS Lambda, API Gateway, DynamoDB, and Cognito. We are looking for the best practices for development. How can 5 developers develop without stepping on each other toes? Is it better to have individual accounts and use cloud formation templates that can be used by each developer?Or use the serverless framework and use a different environment for each developer? It looks like serverless provides the ability to deploy to various environments, but I believe the intent for different environments is for CI/CD where the same code can be moved through various SDLC or specific code can be pushed to a specific environment.

EDIT: THE BUG HAS BEEN FIXED SO PLEASE DELETE these lines below if you added them on your buildspec file.Beforeterraform init, add these lines:export AWS_ACCESS_KEY_ID=`curl --silent 169.254.170.2:80$AWS_CONTAINER_CREDENTIALS_RELATIVE_URI | jq -r '.AccessKeyId'`
export AWS_SECRET_ACCESS_KEY=`curl --silent 169.254.170.2:80$AWS_CONTAINER_CREDENTIALS_RELATIVE_URI | jq -r '.SecretAccessKey'`
export AWS_SESSION_TOKEN=`curl --silent 169.254.170.2:80$AWS_CONTAINER_CREDENTIALS_RELATIVE_URI | jq -r '.Token'`It is more readable.

I am accessing AWS sdk and its services like this in my code:var aws = require('aws-sdk');
const s3 = new aws.S3();I want to see what are the credentials being picked up when I initialise the S3 object. I tried following ways and clearly I am unable to figure out from the documentation how to use the methods and classes properly.var credo = aws.config.Credentials().get();
var credo = aws.config.Credentials;
var credo = aws.config.credentials;
var credo = aws.Credentials().get();
var credo = aws.Credentials();
var credo = aws.Credentials;Can someone tell me the right way to get this data? I am not finding aws documentation easy to understand for this part.Edit: I am able to update credentials in code usingaws.config.update({accessKeyId: 'xxx', secretAccessKey: 'yyy', sessionToken:'zzz'I want to see what these values are when I dont set them like this. Process environment variables are not set. I have credentials file set up correctly.

First, define the output in your ec2 module:output "instance_ids" {
value = ["${aws_instance.web.*.id}"]
}Note: the resource namewebis an example. Please specify the actual resource name in the module.Next, declare the list variable in your elb module:variable "instances" {
type = "list"
}Finally, pass the output of the ec2 module to the elb module:module "instances" {
source = "../../../../modules/ec2"
ami = "ami...."
number_of_instances = 2
instance_type = "t2.micro"
}
module "elb" {
source = "../../../../modules/elb"
name = "some elb"
instances = ["${module.instances.instance_ids}"]
}

I'm trying to get working two basic lambdas using Python2.7 runtime for SQS message processing. One lambda reads from SQS invokes and passes data to another lambda via context. I'm able to invoke the other lambda but the user context is empty in it. This is my code of SQS reader lambda:import boto3

client = boto3.client('lambda')
client.invoke(
FunctionName='LambdaWorker',
InvocationType='Event',

)And this is how I'm trying to inspect and print the contents of context variable inside invoked lambda, so I could check logs in CloudWatch:memberList = inspect.getmembers(context)
for a in memberList:

I have two EC2 instances running in a custom VPC, with one running Ubuntu 16.04 and the other running Amazon Linux 2017.03. I have also assigned a IAM Role that allows read and write access to all S3 buckets.However when I try to run the copy command, to copy a file from the instance to the S3 bucket, it fails on the Ubuntu server. The command I run on both servers is:aws s3 cp /myfolder/myfile.txt s3://mybucket/backups/It gives the following error on Ubuntu:upload failed: ../../myfolder/myfile.txt to s3://mybucket/backups/myfile.txt seek() takes 2 positional arguments but 3 were givenEverything else works, for example, downloading a file from the bucket to the server through the copy command. There is no problem in the VPC setting and neither the IAM Role nor the Security Group, since the same applies to the other server running Amazon Linux.PS: Running the copy command with the --dryrun switch gives no error on the Ubuntu server.

This is caused by abug in argparsethat was fixed in Python 3.4.The awscli is written in Python and it uses theargparse moduleto parse the command line. It also uses theaction="version"featureof argparse to simplify version printing. This prints the version string to stderr prior to Python 3.4 and prints to stdout in Python 3.4+.
|
Why standard checkaws --versionprints the expected output to the stderr, not stdout?$ aws --version 2>err.log
$ cat err.log
aws-cli/1.11.65 Python/2.7.13 Darwin/16.5.0 botocore/1.5.28
$ aws --version > out.log
aws-cli/1.11.65 Python/2.7.13 Darwin/16.5.0 botocore/1.5.28
$ cat out.log
$It would make sense to write the result into stdout if command completed successfully. Other commands likeaws ec2 describe-imagesoraws ec2 describe-instanceswrite the output to the stdout correctly.Checked on CentOS and MacOS.

You won't be able to extract EBS details fromaws_instancesince it's AWS side that provides an EBS volume to the resource.But you can define a EBSdata sourcewith some filter.data "aws_ebs_volume" "ebs_volume" {
most_recent = true
filter {
name = "attachment.instance-id"
values = ["${aws_instance.DCOS-master3.id}"]
}
}
output "ebs_volume_id" {
value = "${data.aws_ebs_volume.ebs_volume.id}"

You don't doanythingdifferently when using an S3 VPC endpoint after you configure it. Nothing in your code changes.When a subnet in a VPC is associated with a route table that is configured for a VPC endpoint, only one thing happens:all of the public IP addresses for S3 in your region are routed to the VPC endpoint instead of following the default route.That's it.Theprefix listpl-xxxxxxxxin your route table represents a list of all the public subnets associated with S3 in your region. The list is automatically maintained by the AWS infrastructure. When an instance sends traffic to S3, it does a DNS lookup to find an IP address for the bucket. When it connects to that IP address, if the route table for the instance's subnet includes an entry for that prefix list using the VPC endpoint for S3, it connects to S3 over the endpoint.All instances in subnets associated with the specified route tables automatically use the endpoint to access the service; subnets that are not associated with the specified route tables do not use the endpoint to access the service.http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/vpc-endpoints.html#vpc-endpoints-routing

Will it's simplest form passing only Bucket, Key and SourceFile attend my goals?The answer isYesit will serve your purpose but if you use Metadata then you can have more control over your object.According to AWS documentation about Object Metadata,There are two kinds of Meta data:System metadata: Metadata such as object creation Date, Last-Modified, Content-Length are system controlled where only Amazon S3 can modify the value.User-defined metadata: You can set/modify optional information as a name-value (key-value) pair when you send a PUT or POST request to create the object and you can grab them in future also.Use Case:If you have your bucket configured as a website, sometimes you might
want to redirect a page request to another page or an external URL. In
this case, a web page is an object in your bucket. Amazon S3 stores
the page redirect value as system metadata whose value you control.
When you create objects, you can configure values of these system
metadata items or update the valuesFor more info about Object Meta Data,http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingMetadata.html#object-metadata

'Key' => $keyname,
'SourceFile' => $filepath
));Considering that my app is going to insert photos and they must stay in S3 until I order to delete it, what are the pros and cons of setting metadata on them, likeContentType,ContentEncodingand others?Will it's simplest form passing onlyBucket,KeyandSourceFileattend my goals?

You need to set your S3 bucket as aStatic Website(it's an option in S3 to set your bucket as such). The domain name will then change to something likehttp://static.my-company.com.s3-website-us-east-1.amazonaws.com., which is what you will want to set the CNAME record to in Route 53.Note that you cannot set a CNAME record to a directory like you are currently doing, it has to be a resolvable domain.

I have a file in my AWS bucket:https://s3.amazonaws.com/static.my-company.com/media/my-file.jpg.Currently I'm accessing that file in myindex.htmlfilewww.my-company.com. I havemy-company.comas a hosted zone in AWS Route 53.But in thatindex.html, I don't want it to be obvious that this asset is in an AWS bucket. I want it to appear as if it is hosted in on my own domain's servers. So instead ofhttps://s3.amazonaws.com/static.my-company.com/media/my-file.jpg, I want it to be addressed ashttps://static.my-company.com/media/my-file.jpg. How can I do that?I tried inserting a CNAME record in Route 53 that would pointstatic.my-company.comtos3.amazonaws.com/static.my-company.com. But that didn't work.

}However, looking at your attempt of using wildcard in place of account id, I wanted to emphasize that following is possible but puts your company at security risk. It violates theprinciple of least privilege.Access to assume any role in any AWS account (INSECURE)"Resource": [
"arn:aws:iam::*"
]Access to assume 'MyRole' in any AWS account (INSECURE)"Resource": [
"arn:aws:iam::*:role/MyRole"
]With this wildcard access, IAM user can assume 'MyRole' (or any role) on behalf of your company in any third-party AWS account.

Which condition can I apply to limit an IAM to only assume roles with a specific name ?This user has a Trusted Relationship on multiple AWS accounts, which all contain a role names "MyRole". So I want a condition like:Assumed RoleARN ~= arn:aws:iam::[0-9]*:role/MyRoleThanks

Waiters have configuration parameters'delay' and 'max_attempts'
like this :waiter = rds_client.get_waiter('db_instance_available')
print( "waiter delay: " + str(waiter.config.delay) )waiter.py on github
|
I started migrating my code to boto 3 and one nice addition I noticed are the waiters.I want to create a snapshot from a db instance and I want to check for it's availability before I resume with my code.My approach is the following:# Notice: Step : Check snapshot availability [1st account - Oregon]
print "--- Check snapshot availability [1st account - Oregon] ---"
new_snap = client1.describe_db_snapshots(DBSnapshotIdentifier=new_snapshot_name)['DBSnapshots'][0]
# print pprint.pprint(new_snap) #debug
waiter = client1.get_waiter('db_snapshot_completed')
print "Manual snapshot is -pending-"
sleep(60)
waiter.wait(
DBSnapshotIdentifier = new_snapshot_name,
IncludeShared = True,
IncludePublic = False
)
print "OK. Manual snapshot is -available-",but the documentation says that it polls the status every 15 seconds for 40 times. That is 10 minutes. Yet, a rather big DB will need more than that .How could I use the waiter to alleviate for that?

The problem is not putting images in version control. The problem is putting
images in version controlalongside your code. If you want to host a
separate repo for images only, knock yourself out, but do not include them in
a repo with actual code.The great aspect of a site like GitHub isit makes software collaboration easier. I can:fork a projectmake changescommitpull requesthttp://hub.github.com#contributorAdding images to a code repo makes software collaboration harder.Anyone who wants to clone your repo is going to have to deal with the extra
size, unless you put the images on a different branch, then they can dogit clone --single-branchImages do not really belong in version control. Version control is great
because you can do line or word diffs for each change, to see how the code
changes over time. You are never going to diff an imageFor code, Git is much better option than AWS. For images, you should be asking
yourself: what does Git do for images better than AWS. The answer is nothing
really other than allowing you to put everything together. It is tempting, but
I would really avoid doing this.

I'm working on a Jekyll project hosted on Github Pages, and wondering what the most advisable way to host images might be.Right now, all the site's images are hosted on AWS, which is fine, but adds a (slight) amount of complexity. Total number of images hangs around 200+, and probably won't go over 500 for the foreseeable future.I'd been advised by peers to NOT host images on Github Pages, but haven't gotten any concrete answers as to why one shouldn't.

Ok, so I found it. Here it is possible to manage all the AWS IoT things:http://docs.aws.amazon.com/iot/latest/apireference/API_Operations.html
|
I am wondering how one creates many "things" in the AWS IoT solution via API without using the AWS web interface since this is not realistic in case I want thousands or millions of things. I guess you could write some script utilizing the "aws" client described here "http://docs.aws.amazon.com/iot/latest/developerguide/thing-registry.html" but thats not optimal if I want to control it from another service.I assumed there would be a RESTish API to do this but it doesn't seem like it if I read the docs:"You use the AWS IoT console or the AWS CLI to interact with the registry."Anyone who created thousands/millions of things - how did you interact with AWS IoT?

FromhereSomething like this should work to allow User1 to only access User1's folder:{
"Version":"2012-10-17",
"Statement": [
{
"Sid": "AllowUserToSeeBucketListInTheConsole",
"Action": ["s3:ListAllMyBuckets", "s3:GetBucketLocation"],
"Effect": "Allow",

},
{

},
{
"Sid": "AllowAllS3ActionsInUserFolder",
"Effect": "Allow",
"Action": ["s3:*"],
"Resource": ["arn:aws:s3:::user1/*"]
}
]
}Apply that as User1's policy, and they should only be able to access theuser1/folder. The"s3:prefix":["","/"]...part can probably be changed, but I'm not familiar enough with the policy language to know how.If you substitute user2 for user1 in User2's policy, User2 should only be able to access theuser2/folder, and so on.

I have two users User1 and User2 that each have an IAM account in AWS. I have an s3 bucket "external_bucket.frommycompany.com". In that bucket is a folder for each user account "User1" and "User2". I want to grant R/W access to User1 to the User1 folder only and R/W access to User2 to the User2 folder only. I don't want them to be able to see each others' folders in the root directory of external_bucket.frommycompany.com. Is there a way to set up their IAM Policies such that this is possible?My goal is to enable our users to connect to the S3 bucket from an S3 browser app like cloudberry so they can upload and download files to their folders only.Any advice on the best design for this is welcome.

In API Gateway, major versions should be represented by separate APIs. You can use the custom domain feature to map base paths to each API (i.e. myapi.com/v1 => API 1, myapi.com/v2 => API 2). You can also make use of the import/export functionality to manage changes between APIs.Using separate accounts per environment is actually a suggested best-practice. I would suggest taking a good look at CloudFormation to manage your workflow - a single CloudFormation template would work well across multiple accounts.

I am having trouble implementing a viable versioning scenario with API Gateway + Lambda. My requirement is to have major versioning at the API level but then minor versioning at the service level.

There might be a better way but I've just tested this one and it works wellNote: If you use EC2 classic you can use theaws ec2 release-address --public-ip <x.x.x.x>command to release elastic IP otherwise you must useaws ec2 release-address --allocation-idEC2-Classicaws ec2 describe-addresses --query 'Addresses[].[PublicIp,AssociationId]' --output text | \
awk '$2 == "None" { print $1 }' | \
xargs -I {} aws ec2 release-address --public-ip {}EC2-VPCaws ec2 describe-addresses --query 'Addresses[].[AllocationId,AssociationId]' --output text | \
awk '$2 == "None" { print $1 }' | \
xargs -I {} aws ec2 release-address --allocation-id {}What those commands are doing:List all ElasticIP information and query only theAssociationIdfield along with either thePublicIporAllocationIdKeep only the records where theAssociationIdfield isNoneand print either thePublicIporAllocationIdvaluePass this value to therelease-addresscommand to actually release it.

Federating with Cognito identity is free, so you will not be charged for the unauthenticated use case you mentioned above. See the last line of Cognito Identity section of the Cognito pricingdoc.If you are using Cognito user pools, which enables you to create your own directory and allows to manage the username and password based login of your user, you will be charged based on MAUs. No matter how many times the same user logs in/opens or closes the app in a given calendar month, it will be counted as a one MAU.
|
AWS Cognito doco states that its pointless to store the ID that will generated for an access request by an Unauthenticated user. Their pricing states that charges are based on Monthly Active users i.e active identities received via credentialsProvider.getIdentityId() call.So I were to implement it in an app or website, and the user either closes the app or website and revisit at a later point that a new ID would be generated and assigned . And that count will be added to the total MAU count?For ex: if the same user opens/closes the app/website 200 times a day.Will it incur 200 MAUs?

};When you give it an event like{

}It will give this output:"callback({\"test\":\"data\"})"So far, so good. Now you come to API Gateway and in Integration Response part you write this$util.parseJson($input.json('$'))Than you will getcallback({"test":"data"})as output when you invoke the API Gateway endpoint.

I have a Python lambda script that shrinks images as they are uploaded to S3. When the uploaded filename contains non-ASCII characters (Hebrew in my case), I cannot get the object (Forbidden as if the file doesn't exist).Here's (some of) my code:s3_client = boto3.client('s3')
def handler(event, context):
for record in event['Records']:
bucket = record['s3']['bucket']['name']
key = record['s3']['object']['key']
s3_client.download_file(bucket, key, "/tmp/somefile")This raisesAn error occurred (403) when calling the HeadObject operation: Forbidden: ClientError. I also see in the log that the key contains characters like%D7%92.Following the web I also tried to unquote the key according to some sources (http://blog.rackspace.com/the-devnull-s3-bucket-hacking-with-aws-lambda-and-python/) like so, with no luck:key = urllib.unquote_plus(record['s3']['object']['key'])Same error, although this time the log states that I'm trying to retrieve a key with characters like this:פ×קס×.Note that this script is verified to work on English keys, and the tests were done on keys with no spaces.

You should not mutate the default service configuration. Instead, each service client provides the following class methods:+ register[ServiceClientName]WithConfiguration:forKey:
+ [ServiceClientName]ForKey:For example, forAWSS3TransferUtility, they are:+ registerS3TransferUtilityWithConfiguration:forKey:
+ S3TransferUtilityForKey:In this way, you can pass a different service configuration for each service client in the runtime. By following this pattern, you can avoid the unintentionally "polluted" default service configuration bugs that can be very difficult to debug.

I've integrated theAWS iOS SDK(v.2.3.6) into my application. It works fine and good, except that I've noticed thatdefaultServiceManagerhas a disclaimer:"You should use this singleton method instead of creating an instance of the service manager".I ordinarily wouldn't have an issue with this, except it'sdefaultServiceConfigurationis immutable:"This property can be set only once, and any subsequent setters are ignored."I have a requirement that a service configuration (ie. identityPoolId + region) be able to change at runtime.What are the possible ways around this? I'd love to be able to just reset the service configuration at any point, but that's unlikely given what the documentation says.

Lambda keeps a worker active for a period of time and will (as you have noticed) remove that worker after a period of time of inactivity. The following is a copy of a set of suggestions posted onour forums:A few suggestions:Keep your Lambda function "warm". If it's invoked infrequently you will incur an overhead "cold start" cost as Lambda needs to allocate
resources to serve your request. See this post for more details.Invoke your Lambda function with resource-based permissions as opposed to role-based. This is to avoid the overhead of API Gateway
needing to make an assumeRole() request to STS. Resource-based
invocation is default if you set it up in the console.If appropriate, consider turning on caching for your API.Is your API doing any transformations of the request or response via mapping templates? This will obviously incur overhead linear with
the complexity of the transformation.A note, #1 should really only be used as alast resortassuming none of the other options work for you.

I've been tinkering with nodejs code in AWS Lambda, called by some API Gateway endpoints. I've noticed that after a certain amount of time passes without any API Gateway calls, the next API Gateway request will time out. I'll get the standard Lambda error message saying the function timed out. However, subsequent HTTP requests to trigger my Lambda work fine.Superficially, it looks like something is going into "idle" mode and needs to be charged up before the API Gateway-Lambda request can work properly. I've considered setting up a wget cron to keep things non-idle, but is there a real fix and how can I better understand what's happening?

Amazon S3 does not have extensive re-writing capabilities.You can specify a default document to read when a directory reference is specified. For example, you can specify that the default document isindex.html. That way, if/is requested, then it will serve up /index.html. But this is a per-bucket setting, so you cannot have different rules for different folders.You could modify your Jekyll configuration to generatesubpages/entry1/index.htmlfromsubpages/entry1.html. This way, your URLs will continue to work.

Looks like theConfigurationEndpoint.Addressis only supported for Memcached clusters, not for Redis. Please seethis relevant discussionin the AWS forums.Also, theAWS Auto Discovery docs(still) state:NoteAuto Discovery is only available for cache clusters running the
Memcached engine. Redis cache clusters are single node clusters, thus
there is no need to identify and track all the nodes in a Redis
cluster.Looks like your 'best' solution is to query the individual endpoint(s) in us, in order to determine the addresses to connect to, usingAWS::CloudFormation::Initas is suggested on the AWS forums thread.UPDATEAs@slimdrivepointed out below, this IS now possible, through theAWS::ElastiCache::CacheCluster. Please read further below for more details.

If the instance is EBS-based, you can do the following:Get acorrectcopy of theauthorized_keysfile ready. Get it off another one of your instances, or reconstruct it from whole cloth, or grab it off a snapshot, or use a new pem file, or whatever.Stop the instance you can't reach (do not terminate it). This step is unavoidable. If you can't stop the instance because it's running something important, you're SOL.Detach the root volume from the stopped instance. It should be something like/dev/sda1. Be sure to give it a name so you can find it in your volume list.Attach it to a different instance at another mount point, say/dev/sdp.Mount the volume into a tmpdir on that instance. Say withmkdir /tmp/myrootvol && mount /dev/xvdp /tmp/myrootvol. Note the device name will vary based on your version of Linux (if you're using Linux at all). Much older versions will use different nomenclature.At this point, you've got a filesystem, a root volume, mounted at/tmp/myrootvol. Fix theauthorized_keysfile, then unmount the device, and detach the volume.Reattach the volume to the original instance at/dev/sda1or whatever device name it was originally attached at.Start that instance back up.There you go. You'll have an accessible EC2 instance. But wow that was a pain wasn't it?

I accidentally overwrote the entries in .ssh/authorized_keys.
Now I am no longer able to connect to my EC2 instance using my .pem file.

Someone who can give a simplified explanation/instructions on this is much appreciated.Unfortunately, there are no active ssh sessions.. :(

You have to download the file to the server where PHP is running first. S3 uploads are only for local files - which is why$_FILES["files"]["tmp_name"]works - its a file that's local to the PHP server.
|
Here is my code, which works for forms upload (via $_FILES) (I'm omitting that part of the code because it is irrelevant):$file = "http://i.imgur.com/QLQjDpT.jpg";
$s3 = S3Client::factory(array(
'region' => $region,
'version' => $version
));
try {
$content_type = "image/" . $ext;
$to_send = array();
$to_send["SourceFile"] = $file;
$to_send["Bucket"] = $bucket;
$to_send["Key"] = $file_path;
$to_send["ACL"] = 'public-read';
$to_send["ContentType"] = $content_type;
// Upload a file.
$result = $s3->putObject($to_send);As I said, this works if file is a$_FILES["files"]["tmp_name"]but fails if $file is a valid image url with Uncaught exception 'Aws\Exception\CouldNotCreateChecksumException' with message'A sha256 checksum could not be calculated for the provided upload body, because it was not seekable. To prevent this error you can either 1) include the ContentMD5 or ContentSHA256 parameters with your request, 2) use a seekable stream for the body, or 3) wrap the non-seekable stream in a GuzzleHttp\Psr7\CachingStream object. You should be careful though and remember that the CachingStream utilizes PHP temp streams. This means that the stream will be temporarily stored on the local disk.'. Does anyone know why this happens? What might be off? Tyvm for your help!

The reason is S3 actually has a flat structure. There are no folders but it just recognizes the forward slashes so groups the ones having the same prefix under same folder. So in your example "/BF/MUSIC" would be just another object, not an empty folder.In Amazon S3, buckets and objects are the primary resources, where
objects are stored in buckets. Amazon S3 has a flat structure with no
hierarchy like you would see in a typical file system. However, for
the sake of organizational simplicity, the Amazon S3 console supports
the folder concept as a means of grouping objects. Amazon S3 does this
by using key name prefixes for objects.Source:AWS Documentation: Working with Folders

TL; DR: There can only be one Worker per Shard. Any additional Workers will sit idle.If you have a Kinesis stream with two shards, and you run an app on a single instance that leverages the KCL, the app will run two workers in separate threads-- one Worker per Shard (per thread).If you run two instances, your app will run a single Worker on each instance in a thread-- two instances, one worker each; one Kinesis stream, two shards.Each worker takes out a lease against a shard in a stream so no other worker of the same app can read the same shard. The Worker stores the lease information in Dynamo DB so other Workers can read it.If you were to run 3 instances in this scenario, one of the instances would sit around waiting for a Worker on one of the other instances to lose its lease. Once one of the other Workers loses its lease, the third Worker could pick up the stream and begin processing.
|
The AWS Kinesis stream documentationmentionsTypically, when you use the KCL, you should ensure that the number of instances does not exceed the number of shardsWhat would be the consequence if the number of instances exceeds the number of shards? I plan on running one worker per Web server (separate thread). So I want to know whether it isrequiredto check and compare the number of shards and running workers when a new web server instance is started. Or can one just start another worker without any side effect if the number of workers exceeds the number of shards.
|
What happens if the number of workers is > number of shards when using KCL with AWS Kinesis streams?

I found the solution. The problem was that in the POST request you need to send your body as a string and not a JSON object and that string needs to be formatted correctie '{"key1": "val1","key2": 22,"key3": 15,"key4": "val4"}'like so:function post() {
$.ajax({
url: "https://myapi.us-east-1.amazonaws.com/myStage/myPath",
type: "POST",
data: '{"key1": "val1","key2": 22,"key3": 15,"key4": "val4"}',
mozSystem: true,
dataType: "text", //set to"json" usually
success: function (result) {
switch (result) {
case true:
processResponse(result);
break;
default:
resultDiv.html(result);
}
},
error: function (xhr, ajaxOptions, thrownError) {
alert('error ' + xhr.status + ' ' + thrownError);
alert(thrownError);
}
});
};

I have a simple POST method connected to a lambda function in myAWS API Gateway.When I perform a test (via the Gateway API console) everything works fine and the test gets the results I am looking for. Its simple - post a JSON, get back a JSON.However, after deploying the API and then sending the same JSON used in the test (via http post), I am getting'Could not parse request body into json'.Does anyone know what I may be doing wrong?
Note: I am not looking to use models, I just want to pass-through the JSON. I believe that when Amazon writes things like 'input passthrough'
they mean that the input can pass through to the lambda function.Here are images of my AWS Gateway API setup:METHOD REQUEST:INTEGRATION REQUEST:METHOD RESPONSE:INTEGRATION RESPONSE:

You need to changeTags[?Key==Name].Value[]toTags[?Key==Name].Value[] | [0]; I think it's becauseTags[?Key==Name].Value[]returns an array which the text output format doesn't know how to put on a single line, piping to[0]extracts the (single) element out for you. So your full query should be :aws ec2 describe-instances --query 'Reservations[].Instances[].[Tags[?Key==`Name`].Value[] | [0], Placement.AvailabilityZone,InstanceType,State.Name]' --output text
|
How do I use AWS CLI to list all instances with name, state, instance size and AZ in the same line?I got close with this:aws ec2 describe-instances --query 'Reservations[].Instances[].[Tags[?Key==`Name`].Value[], Placement.AvailabilityZone,InstanceType,State.Name]' --output textBut that outputs the instance name below the rest. I want to keep them on the same line so I can copy to a spreadsheet.

:secret_access_key => 'your secret-access-key'
},
:url =>':s3_domain_url',
:path => '/:class/:attachment/:id_partition/:style/:filename'
}You can then remove the:urland:pathconfig from your model.

Amazon's permissions model divides API Gateway permissions into two services:Amazon API Gateway- Permissions for clients, currently the only action isexecute-api:invoke.Manage - API Gateway- Admin permissions for configuring the API Gateway, which has CRUD actions fitting theapigateway:*spec.The policy you have applies to the Manage API Gateway service, the simulation should work if you select that.This same separation is visible in the regular IAM policy wizard, where "Manage - API Gateway" sorts to the bottom of the service list where you can't see it.
|
The AWS IAM Policy Docs for AWS (shown here) indicate that the following policy gives full access for a role to hit the API Gateway{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"apigateway:*"
],
"Resource": [
"*"
]
}
]
}When simulating that policy with API Gateway as the target, the policy denies access. This seems like a direct contradiction to the provided documentation.

You can achieve what you want with a custom filter plugin.Create a directory in the root of your playbook calledfilter_pluginsand create a file in there calledmake_rules.pywith the following contents:def make_rules(hosts, ports, proto):
return [{"proto": proto,
"from_port": port,
"to_port": port,
"cidr_ip": host} for host in hosts for port in map(int, ports.split(","))]
class FilterModule(object):
def filters(self):
return {'make_rules': make_rules}Then you can do this:- hosts: localhost
gather_facts: False
vars:
ip_addresses:
- 1.2.3.4/32
- 2.3.4.5/32
tasks:
- ec2_group:
name: security-group-name
description: Security group description
vpc_id: vpc-1234567
region: us-east-1
profile: profile-name
purge_rules: true
rules: {{ ip_addresses | make_rules('123', 'tcp') }}Taken from:https://gist.github.com/viesti/1febe79938c09cc29501
|
I was trying to use Ansible to add IP addresses to an AWS security group.I came up with a task syntax that looks like this:- hosts: localhost
gather_facts: False
vars:
ip_addresses:
- 1.2.3.4/32
- 2.3.4.5/32
tasks:
- ec2_group:
name: security-group-name
description: Security group description
vpc_id: vpc-1234567
region: us-east-1
profile: profile-name
purge_rules: false
rules:
- proto: tcp
from_port: 123
to_port: 123
cidr_ip: "{{ item }}"
with_items: ip_addressesThis does not do exactly what I was looking for as it basically runs theec2_grouptask multiple times instead of just looping over the rules.This also does not work if I set thepurge_rulestotrueas then it will purge all existing rules on each iteration, effectively removing all but the last IP address on the list.I'm wondering if there is something similar towith_itemsthat I can apply to therulesattribute to provide it a list of IP addresses but callingec2_taskonly once?

I believe you're asking the same thing asAmazon Cloudsearch : Filter if existsTo summarize the options from there:Add a new boolean field called 'has_target_date'Set a default target_date (eg 1/1/1970) to mean that it doesn't existThe hack: (range field=target_date [0,})Any of those options should work with the QUERY_GOES_HERE portion of your question.
|
Is there a CloudSearch structured query to return results that do not have a value within a field? For example, I have a field calledtarget_datethat does not always have a value and I want to return all results with no target_date. This field is not zero'd out or set to a default; it doesn't exist at all for items without the date.There is another case too. I need to return all results after atarget_dateAND include any results without an existing date. The structured query I am using istarget_date:['2000-03-03T00:00:00Z',}. The query to find non-existing dates should work with anandoperator, like:(and target_date:['2000-03-03T00:00:00Z',} [QUERY_GOES_HERE])

+50If you're asking this question you have probably taken AWS as far as you can go with the provided code sample.I have found most of the async upload functionality provided by AWS to be more theoretical, or better suited for limited use cases, instead of being production ready for the mainstream- especially end users with all those browsers and operating systems:)I would recommend rethinking the design of your program: create your own C# upload turnstile and keep the AWS SDK upload functions running as a background process (or sysadmin function) so that AWS servers are handling only your server's time.
|
I am currently building an application in C# that makes use of the AWS SDK for uploading files to S3.However, I have some users who are getting the "Request time too skewed" error when the application tries to upload a file.I understand the problem is that the user's clock is out of sync, however, it is difficult to expect a user to change this, so I was wondering, is there any way to get this error not to occur (any .NET functionality to get accurate time with NTP or the alike?)Below the current code I am using to upload files.var _s3Config = new AmazonS3Config { ServiceURL = "https://s3-eu-west-1.amazonaws.com" };
var _awsCredentials = new SessionAWSCredentials(credentials.AccessKeyId, credentials.SecretAccessKey, credentials.SessionToken);
var s3Client = new AmazonS3Client(_awsCredentials, _s3Config);
var putRequest = new PutObjectRequest
{
BucketName = "my.bucket.name",
Key = "/path/to/file.txt",
FilePath = "/path/to/local/file.txt"
};
putRequest.StreamTransferProgress += OnUploadProgress;
var response = await s3Client.PutObjectAsync(putRequest);

As Eric mentioned, currently Lambda doesn't offer a REST endpoint to run the function and return its result, but may in the future.Right now, your best bet would be to use a library likelambdaws, which wraps the function deployment and execution for you and handles returning results via an SQS queue. If you'd like more control by rolling your own solution, the process is straightforward:Create an SQS queueHave your Lambda function write its result to this queueIn your client, poll the queue for a result

I am using the test function from AWS console:console.log('Loading event');
exports.handler = function(event, context) {
console.log('value1 = ' + event.key1);
console.log('value2 = ' + event.key2);
console.log('value3 = ' + event.key3);
context.done(null, 'Hello World'); // SUCCESS with message
};And calling it in nodejs as follows:var params = {
FunctionName: 'MY_FUNCTION_NAME', /* required */
InvokeArgs: JSON.stringify({
"key1": "value1",
"key2": "value2",
"key3": "value3"
})
};
lambda.invokeAsync(params, function(err, data) {
if (err) {
// an error occurred
console.log(err, err.stack);
return cb(err);
}
// successful response
console.log(data);
});and everything works fine://Console Output
{ Status: 202 }But I was expecting to receive the message from context.done(null, 'Message') as well...Any idea how to get the message?

Both approaches can work. Here's why I would pick the Reports API:Reports are more scalable. I believe MWS reports can return an unlimited number of records.ListOrderscan only return a maximum of 100 orders. You can get more usingListOrdersByNextToken, but that brings throttling into the problem and it is not clear whether or not you're just paging by an offset (which could cause lost/duplicate orders) or whether it is a snapshot.You can acknowledge reports and filter on unacknowledged reports. Orders can be acknowledged too, but I don't think there is a way of filtering ListOrders based on acknowledgement status.Reports can be scheduled to auto-generate on an interval, as often as every 15 minutes. This means that it may not be as many calls as you think: really, it's only three every interval: one to list unacknowledged order reports, one to pull the report you want and one to acknowledge it.
|
I'm trying to integrate the orders from Amazon Marketplace into our system. I did that before with Magento and thought this should be easy as that, but somehow I got stuck.I downloaded the Java APIs fromAmazonand started playing around with the examples.So far so good - I was able to get them running.
But playing with theReports APIand theOrders API, I started to wonder which one to use if I only want to get the unshipped orders to put them into our system.1. doing this with the Report API seems very complicated and involves a lot of calls to the MWS. This is documented by Amazonhere.2. using the Orders API seems pretty straightforward. I only have to create aListOrdersRequest, define what type of orders I want to have and finally get them via aListOrderscall.So my question is:What is the reason to choose the Reports API over the Orders API?Seems like Amazon is recommending the Reports API, but I really do not understand why this should be so complicated. Why should I get Reports when I can get the Orders directly?

Is it possible to set the minimum-seller-allowed-price and maximum-seller-allowed-price prices of products via flat file AND submit it as a feed via the MWS API?Sellers will have to specify a min and max price for all items from 15th Jan 2015 onwards viz:"With effect from January 14, 2015, you will not be able to use the Seller Central preferences to select a blanket “opt-out” from all potential low and high-pricing error rules. The aim is to reduce price error risks to sellers and avoid potentially negative buyer experiences. Instead, you will need to set a minimum and maximum allowed selling price for each product in your inventory. If you do not chose pricing limits for each product, Amazon’s default potential pricing error rules will apply to your products...."So, from reading "https://sellercentral-europe.amazon.com/gp/help/201141430" this implies that it can be done via a "Price & Quantity Inventory" file. However, the solution that I'm after needs to be done via the MWS API.For normal price feeds, I'd set the feed type to _POST_PRODUCT_PRICING_DATA_ too.I don't think that you can set the min and max prices via XML as the price feed XSD does not contain a definition for these fields (not that I can find anyway).Sai.

+25As to #1, if you create an AMI (amazon machine image), you can have everything you want pre-installed on a 'hibernating' image that you can use as a basis for the spot image you start:http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-spot-instances-getting-started.htmlFor #2, you can be notified when a spot instance terminates using SNS:http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-autoscaling-notifications.htmlhttp://docs.aws.amazon.com/AutoScaling/latest/DeveloperGuide/ASGettingNotifications.htmlBTW: You can be notified the the instance was terminated, but onlyafterit terminates. You can't get notified that an instance is about to be shutdown and gracefully save the state - you need to engineer your solution to be OK with unexpected shutdowns.No matter how high you bid, there is always a risk that your Spot
Instance will be interrupted. We strongly recommend against bidding
above the On-Demand price or using Spot for applications that cannot
tolerate interruptions.http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-protect-interruptions.html

I have a long batch job that I'd like to run on AWS EC2 Spot Instances, to save money. However, I can't find the answer to two seemingly critical questions:When a new instance is created, I need to upload the code onto it, configure it, and run the code. How does that get done for Spot Instances, which are created automatically and unattatendly?When an instance is stopped, I wouldpreferhaving some type of notification, so that the state could be saved. (This is not critical, as the batch job will run fine if terminated suddenly - but a clean shutdown is preferred).What is the standard way to deploy spot instances? Is there a way to do manual setup, turn it into a spot instance, and then let it hibernate until the spot price is available?

I wouldn't recommend using your home computer as a web server. Here are the steps it takes to get a java web app up and running exposed to the internet.Buy a domain name from a registrarFind a host provider that gives you some sort of linux VM (CentOS, Debian, RHEL, etc). Lowendbox has some cheap ones. AWS is more expensive but you'll get the same thingModify the DNS for wherever you registered to point to the IP address of the VM you just rented.ssh to your VM and install Java, as well as all the dependencies for your application server (Tomcat, JBoss, Netty, etc) via the command lineMost of these servers run at port 8080 by default, so you will need to find a way to reroute requests from 80 to 8080 (do not run your server directly on 80). Best to let Apache run on 80 and forward the requests to 8080 (dependent on the server that you run)Deploy your application

You can, but the nodes in the other regions areread replicas.You can create one or more replicas of a given source [MySQL] DB Instance within an AWS Region or across AWS Regions and serve high-volume application read traffic from multiple copies of your data [...]Multi-AZ Deployments and Read Replicas use different underlying replication technologies suited to their respective purposes. However, you can use them together for reliable, scalable production deployments.Read replicas have limitations, as you might imagine. You can't write to the replicas (obviously), and there's replication lag, which might lead to data loss if the source database goes down (which is where multi-AZ helps you). TheRDS FAQhas some discussion.

I realise that this is an old thread but in case anyone comes across this, as I did, then check out this thread on the AWS forums for Elasticbeanstalkhttps://forums.aws.amazon.com/thread.jspa?messageID=395052#395052It explains how settings set in the.elasticbeanstalk/optionsettings.file are set using the API in such a way that they can't be changed later, unlike those set in the.ebextensions/*.configfiles.Also, in an incredibly annoying move, the optionsettings file will often set some settings in it which you want to set in the .config file however it automatically re-creates the optionsettings file when running eb start and there's very little that seems possible. This makes using the eb command line tools close to impossible to use if you want to change something like the WSGIPath.

You need to ensure that the server is running on 0.0.0.0 if you need it to be reachable by addressinganyIP of the instance.If you have started it on localhost (127.0.0.1), then the behavior is expected. You can stop the server and re-start it to bind to 0.0.0.0:3000. Things should work.

I believe you have two options to handle situations where new EC2 instances are being created automatically for you:Eithercreate a custom AMIfor your EC2 instances, orCustomize your AWS EB environment.Amazon issues a notice about using custom AMI:s:"After you are running on your own custom AMI, you will no longer receive any
automated updates to the operating system, software stack, or the AWS Elastic
Beanstalk host manager."Personally, I've stuck to using configuration files. Takes a bit of tinkering, but once I got it working it operates pretty well.Good luck!

As far I know EB has an "ephemeral filesystem", but I could store the CeoCity binary in S3… but what about MaxMind C libraries? Has anyone configured EB to use MaxMind's api?(My stack is based on Python/Django)

I think a better test would be to avoid the initial costs/latency incurred in starting up the JVM and loading the classes. Something like:public class TestDynamoDBMain {
public static void main(String[] args) {
try {
AWSCredentials credentials = new PropertiesCredentials(new File("aws_credentials.properties"));
AmazonDynamoDBClient client = new AmazonDynamoDBClient(credentials);
DynamoDBMapper mapper = new DynamoDBMapper(client);
// Warm up
for (int i=0; i < 10; i++) {
testrun(mapper, false);
}
// Time it
for (int i=0; i < 10; i++) {
testrun(mapper, true);
}
} catch (Exception e) {
e.printStackTrace();
}
}
private static void testrun(DynamoDBMapper mapper, boolean timed) {
long start = System.nanoTime();
Model model = mapper.load(Model.class, "hashkey1", "rangekey1");
if (timed)
System.out.println(
TimeUnit.NANOSECONDS.toMillis(System.nanoTime() - start)
+ " (ms) to load Model");
}
}Furthermore, you may consider enabling the default metrics of the AWS SDK for Java to see the fine grain time allocation in Amazon CloudWatch. For more details, see:http://java.awsblog.com/post/Tx1O0S3I51OTZWT/Taste-of-JMX-Using-the-AWS-SDK-for-JavaHope this helps.

I've been testing out DynamoDB as a potential option for a scalable and steady throughput database for a site that will be hit pretty frequently and requires a very fast response time (< 50ms). I'm seeing pretty slow responses (both locally and on an EC2 instance) for the following code:public static void main(String[] args) {
try {
AWSCredentials credentials = new PropertiesCredentials(new File("aws_credentials.properties"));
long start = System.currentTimeMillis();
AmazonDynamoDBClient client = new AmazonDynamoDBClient(credentials);
System.out.println((System.currentTimeMillis() - start) + " (ms) to connect");
DynamoDBMapper mapper = new DynamoDBMapper(client);
start = System.currentTimeMillis();
Model model = mapper.load(Model.class, "hashkey1", "rangekey1");
System.out.println((System.currentTimeMillis() - start) + " (ms) to load Model");
} catch (Exception e) {
e.printStackTrace();
}
}The connection to the DB alone takes about800 (ms)on average and the loading using themappertakes an additional200 (ms). According toAmazon's page about DynamoDBwe should expect "Average service-side latencies...typically single-digit milliseconds." I wouldn't expect the full round-trip HTTP request to add that much overhead. Are these expected numbers even on an EC2 instance?

I had the same problem with running a ruby script (ruby script.rb).
I replace ruby by its full path (/sources/ruby-2.0.0-p195/ruby) and it worked.
in you case, replace "aws" by its full path. to find it:

I have a crontab that fires a PHP script that runs the AWS CLI command "aws ec2 create-snapshot".When I run the script via the command line the php script completes successfully with the aws command returning a JSON string to PHP. But when I setup a crontab to run the php script the aws command doesn't return anything.The crontab is running as the same user as when I run the PHP script on the command line myself, so I am a bit stumped?

We have a whenever cookbook in our repo we use that you would be more than welcome to use here:https://github.com/freerunningtech/frt-opsworks-cookbooks. I assume you're familiar with adding custom cookbooks to your opsworks stacks.We generally run it on its own layer that also includes the rails cookbooks required for application deployment (while not the app server):Configure: rails::configureDeploy: deploy::rails wheneverUndeploy: deploy::rails-undeployHowever, we usually also deploy this instance as an application server, meaning we do end up serving requests from the box we're using for whenever as well.There is one "gotcha", in that you must set your path in the env at the top of the schedule.rb like this:env :PATH, ENV['PATH']
|
Does anyone have experience/success using the whenever gem on aws opsworks? Is there a good recipe? Can I put that recipe on a separate layer and associate one instance with that additional layer? Or is there a better way to do it? Thanks!!!EDIT:We ended up doing it a bit differently...Code:Can’t really post the real code, but it’s like this:in deploy/before_migrate.rb:[:schedule].each do |config_name|

begin

config_name => node[:deploy][:APP_NAME][:config_files][config_name]
)

end
rescue => e

raise "Error processing config for #{config_name}: #{e}"
end
endin deploy/after_restart.rb:execute 'start whenever' do

I can't think of any reason why the SDK code would cause your CPU to go so high. My first guess would be some sort of garbage collection issue. When you upload your data, are you passing in a File object to AmazonS3.putObject, or some sort of stream (including FileInputStream)? Streams can be a little tricky to deal with, since they aren't guaranteed to be repeatable and you have to explicitly provide the Content-Length in the ObjectMetadata as part of your upload, otherwise the SDK has to buffer your upload in memory to calculate the total length. That'd be the very first thing I'd recommend checking out.On a side note.. you should check out theTransferManager APIin the SDK. It gives you a nice simple interface to uploading and downloading files to/from Amazon S3, and have several optimizations built in.If that still doesn't turn up a clue, then I'd recommend making a dead simple repro case for this. Write a single class file that simply uploads a random File to the same S3 key, and leave that running for the same duration as your application code. If you're able to reproduce the problem in that simple setup, then we can take a look at the code and help get it debugged, but with all the other variables involved in your full application code, we can't do much more than guess at what could be happening.

I'm currently working on a server app (JEE) and getting some problems to upload files to AWS S3. I'm using the Java SDK (S3client.putObject) to upload these files. When the server starts, everything happens as expected. Files are generated in the server (EC2 instance) and uploaded to S3 in a few seconds. But after some days, the performance degrades a lot. Files that usually took 5 or 6 seconds to be uploaded need now 10 to 30 minutes (yes, minutes). I profiled the app and the culprit here is the section that does the upload using the AWS Java SDK. Strangely the CPU utilization goes near 100% and stays there for minutes. As this is basically an IO operation, I don't understand why it may need so many CPU cyles to run.
Has anyone eve experienced this behavior?
Any tips on where to look?PS: file size goes from 1 to 50 MB.Thanks a lot!Updates:
The EC2 instance that creates the files and uploads them to S3 is m1.large.
I'm using the 1.6.4 AWS SDK version .

You should be able to usecreateVolumeto create the item.

AmazonEC2Client client = new AmazonEC2Client(credentials);
CreateVolumeResult request = new CreateVolumeRequest(java.lang.Integer size,

Most of the services of Amazon Web Services are in a single region. The only exceptions are Route 53 (DNS), IAM, and CloudFront (CDN). The reason is that you want to control the location of your data, mainly for regulatory reasons. Many times your data can't leave the US or Europe or any other region.
It is possible to create high availability for your services within a single region with availability zones. This is how the highly available services as DynamoDB or S3 are giving such functionality, by replicating the data between availability zones, but within a single region.

I had created a simple table in dynamo called userId, I could view it in the AWS console and query it through some java on my local machine. This morning, however, I could no longer see the table in the dynamo dashboard but I could still query it through the java. The dashboard showed no tables at all (I only had one, the missing 'userId'). I then just created a new table using the dashboard, called it userId and populated it. However, now when I run my java to query it, the code is returning the items from the missing 'userId' table, not this new one! Any ideas what is going on?Ok, that's strange. I thought dynamo tables were not specified by region but I noticed once I created this new version of 'userId' it was viewable under the eu-west region but then I could see the different (previously missing!) 'userId' table in the us-east region. They both had the same table name but contained different items. I didn't think this was possible?

DynamoDB Table Missing?

In my opinion, it's an understandable trade-off DynamoDB made. To be highly available and redundant, they need to replicate data. To get super-low latency, they allowed inconsistent reads. I'm not sure of their internal implementation, but I would guess that the higher this 64KB cap is, the longer your inconsistent reads might be out of date with the actual current state of the item. And in a super low-latency system, milliseconds may matter.This pushes the problem of an inconsistent Query returning chunk 1 and 2 (but not 3, yet) to the client-side.As per question comments, if you want to store larger data, I recommend storing in S3 and referring to the S3 location from an attribute on an item in DynamoDB.
|
I had a use case where I wanted to store objects larger than 64kb in Dynamo DB. It looks like this is relatively easy to accomplish if you implement a kind of "paging" functionality, where you partition the objects into smaller chunks and store them as multiple values for the key.This got me thinking however. Why did Amazon not implement this in their SDK? Is it somehow a bad idea to store objects bigger than 64kb? If so, what is the "correct" infrastructure to use?
|
Why does AWS Dynamo SDK do not provide means to store objects larger than 64kb?

The suggested solution from theAWS Developer Forums:It turns out that cron has the "from" address hard-coded in the source (q.v. "do_command.c" in the cron source), so one does not have influence over what cron transmits to sendmail (which in our case is symlinked to "/usr/bin/msmtp").However, due to the magic of Linux, we do have the ability to alter the stream of text that goes into sendmail.The way I worked around this cron limitation was to move the "msmtp" binary to"msmtp.bin" and then create "/usr/bin/msmtp" that was a shell script:#! /bin/bash
sed -e 's/root .Cron Daemon./[email protected]/' | /usr/bin/msmtp.bin "$@"This is also, AFAIK, the only means one has to set the "debug" flag to msmtp when used in a "global" setting (such as cron, or other cases where sendmail is invoked with arguments you don't control).While the script above is rather simplistic, you can also conditionally alter the text by checking the input arguments for the magic "-FCronDaemon" which is also hard coded in the cron binary. I would be stunned if any other program calls sendmail with "-FCronDaemon".
|
I have a crontab that includes a[email protected]. My server uses msmtp to forward the email to Amazon Simple Email Service. My problem is that output from cron commands never arrives in my mailbox. This is what the msmtp log says:Mar 06 14:26:02 host=email-smtp.us-east-1.amazonaws.com tls=on auth=on user=MY.SES.USER[email protected][email protected]smtpstatus=554 smtpmsg='554 Transaction failed: User name is missing: ?Cron Daemon ?.' errormsg='the server did not accept the mail' exitcode=EX_UNAVAILABLEWhat do I need to do in order to make Amazon SES accept the cron emails?

The type of file depends on the file obviously. Have a look at this:http://en.wikipedia.org/wiki/Internet_media_typeIf you know what exactly is your file, then assign one of these to response ( not mandatory though ). You should also add the length of the file to response ( if it is possible, i.e. if it is not a stream ). And if you want it to be downloadable as an attachment, then add Content-Disposition header. So all in all you only need to add this:var filename = "myfile.txt";
res.set({
"Content-Disposition": 'attachment; filename="'+filename+'"',
"Content-Type": "text/plain",
"Content-Length": data.Body.length
});NOTE: I'm using Express 3.x.EDIT: Actually Express is smart enough to count content length for you, so you don't have to addContent-Lengthheader.
|
I am trying to send a file's content to the client in my request, but the only documentation Express has is it's download function which requires a physical file; the file I am trying to send comes from S3, so all I have is the filename and content.How do I go about sending the content of the file and appropriate headers for content type and filename, along with the file's content?For example:files.find({_id: id}, function(e, o) {
client.getObject({Bucket: config.bucket, Key: o.key}, function(error, data) {
res.send(data.Body);
});
});

In my opinion, it is almost always best to store and return the fewest fields possible — preferably just the ID, unless you explicitly need a feature such as highlighting.Storing a lot of data in your index can have a negative impact on your search performance as your index grows. There is no data that loads faster than no data. Plus, looking up objects by their IDs should be a very cheap operation in your primary data store of choice.Most importantly, if your application is using an ORM to interact with its data store, then the sheer utility of reusing all your domain modeling consistently throughout your application would be hard to overstate.Returning values straight from your search engine can be useful. But, short of using the search engine as a primary data store, I would need averycompelling reason to fragment my domain logic by foregoing an ORM.

The AWS SDK for Ruby (aws-sdk gem) supports enumerating region names:require 'aws-sdk'
ec2 = AWS::EC2.new(:access_key_id => '...', :secret_access_key => '...')
ec2.regions.map(&:name)
=> ["eu-west-1", "sa-east-1", "us-east-1", "ap-northeast-1", "us-west-2", "us-west-1", "ap-southeast-1"]You can also use a client interface to the DescribeRegions call:ec2.client.describe_regions
=> { :region_info=>[
{:region_name=>"eu-west-1", :region_endpoint=>"ec2.eu-west-1.amazonaws.com"},
{:region_name=>"sa-east-1", :region_endpoint=>"ec2.sa-east-1.amazonaws.com"},

After more research and posting on the AWS forum I got a solution although not a full understanding of what happened under the hood. Thought I would post this as an answer if that's okay.Turns out there is a bug in the AMI Version 2.0, which of course was the version I was trying to use. (I had switched to 2.0 because I wanted hadoop 0.20 to be the default) The bug in AMI Version 2.0 prevents mounting of instance storage on 32-bit instances, which is what the c1.mediums launch as.By specifying on the CLI tool that the AMI Version should use "latest", the problem was fixed and each c1.medium launched with the appropriate 350GB of storage.For example./elastic-mapreduce --create --name "Job" --ami-version "latest" --other-optionsMore information about using AMIs and "latest" can be foundhere. Currently "latest" is set to AMI 2.0.4. AMI 2.0.5 is the most recent release but looks like it is also still a little buggy.

I'm using Amazon EMR and I'm able to run most jobs fine. I'm running into a problem when I start loading and generating more data within the EMR cluster. The cluster runs out of storage space.Each data node is a c1.medium instance. According to the linkshereandhereeach data node should come with 350GB of instance storage. Through the ElasticMapReduce Slave security group I've been able to verify in my AWS Console that the c1.medium data nodes are running and are instance stores.When I run hadoop dfsadmin -report on the namenode, each data node has about ~10GB of storage. This is further verified by running df -hhadoop@domU-xx-xx-xx-xx-xx:~$ df -h

According tosome past research, the s3cmd GET operation is about 5 times slower than wget. Keep in mind that s3cmd is a utility designed to retrieve files from your S3 filesystem. It doesn't use the HTTP protocol but instead uses the s3 protocol.The only time I can see using the s3cmd utility is for cases where you're retrieving files you cannot otherwise retrieve using standard HTTP GET methods, like when the files on S3 don't have read permissions or you're doing maintenance on your S3 buckets.Based on your question, I'm assuming you're trying to use this utility in a production system; however, it doesn't appear that was the intention or goals of the utility.For more details, check outperformance testing spreadsheet.As far as costs goes, I'm not an expert on Amazon pricing, but I believe they bill based on actual data transferred, so a 1GB file would cost the same regardless of whether you downloaded it quickly or slowly. It's like the question where someone asks you what is heavier, ten pounds of bricks or ten pounds of feathers.

2) Which one is cheaper?

res.end('hello world!\n');
}).listen(3000, '0.0.0.0', function() {
console.log('Server running on port 3000');
});However when I run it and go tohttp://x.x.x.x:3000/the page doesn't load.I tried the answer onthis questionbut that didn't work either. And changing the host to127.0.0.1or the server ip or emitting it doesn't fix it either.I've also followedthis guidethat says to proxy requests with haproxy. But that did not work either.Is there something in the security tab I have to enable/disable?Edit: The problem was I was using the wrong IP. The IP changes when the instance is restarted.

There is no such stuff as folders in Amazon S3. It is a "flat" file system. The closer you can get to folders is adding prefixes likefoo/bar/filename.txtto your file names.
Even though several S3 tools will show you stuff as if they were contained inside folders, this concept does not exist on S3.Please see this related thread:Amazon s3 Folders Problem
|
Below codes can get 1 single file from AWS 3 but, what about a folder?var _key:int=Account.lessons[dl_i].id;
var dest:String = Conf.Dir+_key;
var request:GetObjectRequest = new
GetObjectRequest().WithBucketName(Conf.bucketName).WithKey(_key+"");
var response:GetObjectResponse = client.GetObject(request);
response.WriteResponseStreamToFile(dest);

"Retired" means that a reserved instance purchase is no longer in effect.Usually this would be because the term expired (1 year, 3 years, etc). However, according tothis thread, it looks like it could also mean that there was a problem processing payment.Either way, retired instances are no longer usable.
|
I can see from billing that we purchased 4 reserved EC2 instances in 2 batches of 2 earlier this year.We are currently using 2 EC2 instances.In the list of purchased reserved instances, I can see 2 listed as active, and 2 listed as retired. Can you tell me what "retired" means and if they are still usable?Thanks

There's business risk and technical risk.Business risk is that you might have to move hosts later for some external reason. VPS's, EC2, etc require more upfront investment, but keep you independent. Tools likeChefcan help with the configuration effort.Technical risk is that your application may not be easily implemented on the platform. Since most VPS options allow you to install arbitrary software, they minimize this, again at the cost of more configuration effort on your part. AFAIK, the largest constraint GAE enforces on you is it's difficult to do long running background tasks. (Working without JOINs and other aspects of de-normalized data requires a different way of thinking, but this approach is fairly common in web applications no matter where they run once the SQL database is larger than a single host can support.)If you can live with both these risks, GAE would appear to save you a substantial amount of effort. If you cannot live with these risks, you should tailor your own environment.As an aside, I find S3 to be worth it no matter your environment. It's far simpler than ensuring your local server static file storage is reliably backed up, and you never have to worry about capacity. It's best if you use it for data that is uploaded but rarely overwritten or deleted (think facebook photo albums).

I have my first app, not that big, but it is the first step. (next big one on the way)Now if I want to put it on my own Linode VPS, I have to configuremod_python or mod_wsgi,as well as memcache, Ngix, mySQL or Postgresql, etc. to make it work. If I put it GAE, All I have to do is convert the models to use GAE's API.What I like about GAE is scaling. (if they can really do it)Then I'd only worry about developing my apps and doing SEO work on them instead of worrying about load share/balance, cache, db / IO redundancy, etc.I don't want to do any porting later on. (I have to decide now and stick with it)So, if you have any experience on this, what do you recommend:1- Use VPS(s) for everthing
2- Use VPS(s) plus Amazon S3
3- Use VPS(s) plus Amazon S3 & SimpleDB
4- Use GAEAlso: Would I be able to get away with not having JOIN rights when using the BigTable?Note: I don't have any spatial need now, but for a location table I might need that later on.I'd like to know what do you think!

You should be able to determine the Sales Rank by querying for the SalesRank response group when doing an ItemLookup with the Amazon Associates Web Service.Example query:http://ecs.amazonaws.com/onca/xml?
Service=AWSECommerceService&
AWSAccessKeyId=[AWS Access Key ID]&
Operation=ItemLookup&
ItemId=0976925524&
ResponseGroup=SalesRank&
Version=2008-08-19Response:<Item>
<ASIN>0976925524</ASIN>
<SalesRank>68</SalesRank>
</Item>See the documentation here:http://docs.amazonwebservices.com/AWSECommerceService/2008-08-19/DG/index.html?RG_SalesRank.html

I've seen several products that will track the sales rank of an item on Amazon. Does Amazon have any web-services published that I can use to get the sales rank of a particular item?I've looked through the AWS and didn't see anything of that nature.

How can I track the sales rank of an item on Amazon programmatically?

I've been having the exact same issue trying to find any information regarding how to get a seller's ID through the SP-API.As far as I can see, the only way to programmatically get the seller's ID is during the app authorization process via oauth:https://developer-docs.amazon.com/sp-api/docs/selling-partner-appstore-authorization-workflowIt mentions in Step 4 that the redirect after authorization includesselling_partner_idas a query parameter. That is the seller account's ID.Unfortunately, I cannot find any way to retrieve the seller ID after the fact. There is a Github issue regarding this missing feature but, unsurprisingly from Amazon, has not gotten very far:https://github.com/amzn/selling-partner-api-docs/issues/492

I want to update the listing quantity on amazon through patchlistingItem API but it requiresSellerID, I can't find any endpoint to get sellerId (I have only a refresh token ) of sellers that are authorized with our website.https://developer-docs.amazon.com/sp-api/docs/listings-items-api-v2021-08-01-reference#patchlistingsitemI have tried this endpoint but cant get sellerIdhttps://developer-docs.amazon.com/sp-api/docs/sellers-api-v1-reference

is there any endpoint in amazon sp api to get seller Id?

There isn't a native solution for Step Functions to achieve this yet.
Another workaround would be to use a simple lambda to convert the type.Edit: A native workaround would be to use the intrinsic functionStates.StringToJsone.g."NumberValue.$": "States.StringToJson("$.numberAsString")"

Is there a way in an aws step function to convert a string to a number?I have a query param that is passed from api gateway to the step function. It is a string with a numeric value. I would like to cast the string to a number in the step function state language, but so far no luck.

An option would be to convert the timestamp and then filter with subtracting an hour from the current time.Assuming the value in timestamp is milliseconds since epoch you can usefrom_unixtime:Based on your sample value provided to see how that works:select from_unixtime(1650578683860/1000e0)Which then gives the result:2022-04-21 22:04:43.860Then you can use DATE_ADD and subtract an hour from CURRENT_STAMP, so the where clause would be something like:WHERE from_unixtime("timestamp"/1000e0) >= DATE_ADD('hour', -1, CURRENT_TIMESTAMP)

I have some data rows in AWS Athena table and I am trying to get the data from the last 1 hour. I am using awswrangler, I will post my snippet below. Basically, instead of querying all data and then filtering out only the last 1 hour with Python, I would like to do that in the Athena SQL query so that I get a faster response (and thus execution time of the program). My code is:import awswrangler as wr
import boto3
session=boto3.Session()
df = wr.athena.read_sql_query(f"""SELECT *
FROM data_table""",
database="database",
keep_files = False,
boto3_session = session).sort_values('timestamp')My progress:
I can get the current timestamp with"SELECT CURRENT_TIMESTAMP", but this will return the timestamp in a date format. In order to get the last 1 hour, my idea is to convert 1 hour to milliseconds as well, and subtract it from the milliseconds of current timestamp and apply it as a filter.NOTE!timestampin the table is in milliseconds.

Looking in theUser Guide, you can see:Resource: which secrets they can access. See Secrets Manager resources.The wildcard character (*) has different meaning depending on what you attach the policy to:In a policy attached to a secret, * means the policy applies to this secret.In a policy attached to an identity, * means the policy applies to all resources, including secrets, in the account.So in the case where it is attached to the secret, it effectively has no meaning that differs from*, but it is when you attach it to an identity that it becomes more useful. Then you can give differing identities different action permissions on various secrets.

I am trying to understand resource based policy in IAM.I understand : it is attached to a resource like s3,KMS, secrets manager etc.My question is what is the significanceResourcein a resource based policy.For example a permission policy for AWS secrets manager(https://aws.amazon.com/premiumsupport/knowledge-center/secrets-manager-resource-policy/){
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": "secretsmanager:*",
"Principal": {"AWS": "arn:aws:iam::123456789999:user/Mary"},
"Resource": "*"
}
]
}Here the Resource is * or the resource can be the ARN of the secrets manager. (Is there any other value allowed in this case ? ) For S3 I can think of the root bucket or other prefixes.So my question is what is the use case for Resource here ? Please let me know if I am reading it wrong.Thanks in advance.

If you useboto3s3 slient, you can get a list of folders:import boto3
s3 = boto3.client('s3')
result = s3.list_objects(Bucket=BUCKET_NAME, Delimiter='/')
for prefix in result.get('CommonPrefixes', list()):
print(prefix.get('Prefix', ''))
|
I want to list all of the folders from my S3 bucket. In my s3 bucket I have folders for example : SF_test_01, SF_test_02, SF_test_03 etc. I usedfor my_bucket_object in my_bucket.objects.all():
print(my_bucket_object)but its returning all paths with folder and file names. Is there anyway how to do it? I want only folder names. I can add that I'm using AWS Lambda function and I have imported boto3

I'll rather suggest to put them in thesamconfig.tomlfile, like:[default.deploy.parameters]
stack_name = "your-application"
s3_bucket = "your-s3-for-cloudformation-stuff"
s3_prefix = "your-folder-name"
...
tags = "Name=\"test-stack\" az:zone=\"infra\""That will propagate tags down to all the resources of the stack (including CloudFormation stack itself)
|
I'm trying to add tags to a stack while using SAM deploy, but they're not showing up.
The SAM cli command code can be found below.sam deploy --stack-name test-stack --resolve-image-repos --capabilities CAPABILITY_NAMED_IAM --no-fail-on-empty-changeset --template-file ./.aws-sam/build/template.yaml --resolve-s3 --tags Name=test-stack az:zone=infraTags are not being created in the CloudFormation stack despite giving the —tag parameter to the cli.Can someone tell me how to add stack-level tags to the CloudFormation stack that is deployed using SAM CLI?

In your sample code, when you use:credentials: rds.Credentials.fromGeneratedSecret('myname')CDK will automatically create anAWS Secrets Managersecret and store it there. You can view the password generated byretrieving the secret.If you want to specify your own password, you can useCredentials.fromPassword. The documentation recommends not to have the password directly exposed in your CDK code for security reasons. You can also useCredentials.fromSecretto read the value from a AWS Secrets Manager secret you have created separately.
