This can be a bit difficult since the command line options for Lambda require that you useaws lambda get-policyin order to find out which resources are allowed to perform thelambda:InvokeFunctionaction on a given function. These permissions aren't shown as part of the lambda configuration foraws lambda get-function-configuration. Usebashandjqto get a list of functions and spit out their allowed invokers. Like this:aws lambda list-functions | jq '.Functions[].FunctionName' --raw-output | while read f; do
policy=$( aws lambda get-policy --function-name ${f} | jq '.Policy | fromjson | .Statement[] | select(.Effect=="Allow") | select(.Action=="lambda:InvokeFunction") | .Condition.ArnLike[]' --raw-output )
echo "FUNCTION ${f} CAN BE INVOKED FROM:"
echo ${policy}
doneThis will list the arn of the resources that are allowed to use the actionlambda:InvokeFunctionon the all Lambda functions returned fromlist-functions.

All subnets within a VPC can communicate with each other by default.In fact, the only way to prevent this is by defining Network ACLs that Deny traffic.So, yes, an instance in one private subnet can connect to an instance in another private subnet (in the same VPC). Just use thePrivate IP addressto connect.
|
I have a VPC, inside there is a public subnet and two private subnets. I configured security groups as well as route tables and I can access ES2 instances in the two private subnets from the instance in the public subnet.Now I want to know if I can directly connect to the instances in one private subnet from the instances in the other private subnets. If yes, how.Thanks,
Philip

This is very likely to be a side-effect of your API Gateway endpoint being configured asEdge Optimizedinstead ofRegional, because with an edge-optimized API, there is a hidden CloudFront distribution provisioned automatically... however, the CloudFront distribution associated with your API is not owned by your account, but rather by an account associated with API Gateway.Edge-optimized APIs are endpoints that are accessed through a CloudFront distribution that is created and managed by API Gateway.—Amazon API Gateway Supports Regional API EndpointsThis creates a conflict that prevents the wildcard distribution from being created.Subdomains that mask a wildcard are not allowed to cross AWS account boundaries, because this would potentially allow traffic for a wildcard distribution's matching domains to be hijacked by creating a more specific alternate domain name -- but, as you noted from the documentation, you can do within your own account.Redeploying your API asRegionalinstead ofEdge Optimizedis the likely solution. If you still want the edge optimization behavior, you can create another CloudFront distribution with that specific subdomain for use with the API. This would be allowed, because you would own the distribution. Regional APIs are still globally accessible.

In Api Gateway I've created one custom domain,foo.example.com, which creates a Cloud Front distribution with thatCNAME.I also want to create a wildcard domain,*.example.com, but when attempting to create it, CloudFront throws an error:CNAMEAlreadyExistsException: One or more of the CNAMEs you provided
are already associated with a different resourceAWS in its docs states that:However, you can add a wildcard alternate domain name, such as
*.example.com, that includes (that overlaps with) a non-wildcard alternate domain name, such as www.example.com. Overlapping domain
names can be in the same distribution or in separate distributions as
long as both distributions were created by using the same AWS account.https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/CNAMEs.html#alternate-domain-names-wildcardSo I might have misunderstood this, is it possible to accomplish what I've described?

DMS is adatamigration service. View is a virtual table(represented by sql code/object) and it does not contain any data by itself like a table does.
|
I'm using AWS DMS to migrate data from one Postgres database to another Postgres database. Everything works fine, except one thing: the views are no replicated on my target database.I've read that this cannot be done between heterogenous database (i.e. from Oracle to Postgres) using DMS, but I imagine that this is possible somehow when we're using the same database.Does someone know how to replicate the views using AWS DMS from Postgres to Postgres?

So the problem was with forwarding of cookies, especially theXSRF_TOKENcookie. Cookies aren't forwarded by default through the cloudfront, you have to set up a whitelist to do that.

Alright hello, I have deployed my Laravel app on AWS ELB and I set up Cloudfront distribution for my app. Now I am facing CSRF Token mismatch. I know that this error can be caused by multiple config values that may be wrong. Now I have managed to fix this issue by myself in the past, but it was a long time ago and I don't know what I did and where. So if you have some tips on what could be wrong and where, then definitely send them my way. ThanksEDIT:The exception happens after switching to Cloudfront. My problem is to get it working with Cloudfront.

Here's the overall strategy:Let PyPDF2 handle the decodingPyPDF2 will be much smarter at determining how to decode the file than you will be. PdfFileReader can read from a stream or a path to a file so can read the file from S3 and prepare it as a byte stream. Let PdfFileReader do the hard work.Preparing the byte streamTo prepare the file stream as a byte stream you can use the BytesIO library.Python 2:from BytesIO import BytesIOPython 3:from io import BytesIOFor your code example:from io import BytesIO
import boto3
from PyPDF2 import PdfReader
s3 = boto3.resource("s3")
obj = s3.Object(bucket_name, itemname)
fs = obj.get()["Body"].read()
reader = PdfReader(BytesIO(fs))

I am trying to get a pdf file stored in one of my S3 buckets in AWS, and get some of its metadata like number of pages, and file size. I successfully get the pdf file from the S3 bucket, getting this when calling print(obj)s3.Object(bucket_name='somebucketname', key='somefilename.pdf')When using PyPDF2.PdfFileReader() I try using the raw file, a UTF-8 decoded file, and a ISO-8859-1 decoded file. The ISO-8859-1 decoded file is the only one that doesn't raise an exception, but when trying to pass it into PdfFileReader as a parameter I get an error, and this tracebackTraceback (most recent call last):

fileobj = open(stream, 'rb')
ValueError: embedded null byteAm I using the wrong encoding type to decode this pdf file, or is it something else like the first argument of pdfFileReader has to be a file path? Is there an easier way to access an S3 pdf object's metadata without having to jump through hoops to get there?Python Scriptimport boto3
from PyPDF2 import PdfReader
s3 = boto3.resource('s3')

Operations on ObjectsPre-signed URL is supported for:GETPUTIt is not supported for:LISTCOPYDELETEThe reason you are gettingSignatureDoesNotMatchis the operation is part of the signature. You cannot change the operation from GET to DELETE and expect the signature to match.

Hi I'm generating the s3 presigned "GET" urls to display images using code modified fromhttps://gist.github.com/kelvinmo/d78be66c4f36415a6b80Ideally I should also be able to generate a presigned delete URL, put it in the browser and the image would get deleted.I would like to modify this for the delete operation, there seems to be no info online on how to do this with a presigned url aside from the aws docs which are vague but say it's possible. I haven't managed to find any online tutorials using presigned urls for delete.https://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectDELETE.htmlI tried just changing the Get to Delete in the request as many docs say but this creates an incorrect signature:SignatureDoesNotMatchThe request signature we calculated does not match the signature you provided. Check your key and signing methodIt looks like the s3 is matching the DELETE signature with PUT signature and saying it doesn't match, so how to do a delete?!Any clues or links would be helpful. I'm assuming the current GET script is sending the wrong parameters or something.

There is no Managed MongoDB Service provided by AWS.However, there are managed MongoDB services which provides hosting on AWS (in addition to Azure, GCP etc. MongoDB Atlas is an example.MongoDB Atlas provides managed mongoDB service with options to host on AWS and you may opt to use that. You can choose the region of your preference and then use VPC Peering feature to make the application servers in your existing VPC/Account communicate with the MongoDB Atlas Setup.You can read more about all these athttps://www.mongodb.com/cloud/atlas

If it's not a production instance, you can start with t2.medium instance. If its a production instance, start with m5.large.Attach a new ebs volume of size 10GB and configure mongodb to use this new volume as the data directory. This helps to scale up your storage easily at later point of time.Make sure you format your ebs volume to have xfs file system before installing mongodb which is required for best performance by mongo.Also, later if you feel like increasing the instace size wheb your traffic increases, just use the "instance modify" option to get it done.

We plan to use MongoDB in production for our website which will be hosted (for the start) on a single ec2 instance.
What is the recommandation for a MongoDB, which will have around 25k documents for the start with low traffic? So far i am not used to AWS, therefore a have no comparison to other dedicated hosters.The "storagesize" of the collection in question will be arond 400MB, "totalindexsize" maybe around 20MB

Suggested approach: A scheduled Lambda function that fires every 3 months and performs 4 steps.Start up your instanceUse the EC2 RunCommand API to remotely execute a command on your lightsail instanceMonitor the command until completeShut down the instanceSome prerequisites:Create a Lambda function and grant it permissions with an IAM role to usessm:*,ec2:startinstancesandec2:stopinstances(This will allow your lambda function to communicate to your lightsail instance and also monitor and send commands.Make the lambda function a scheduled function, so you can trigger it every 3 months automaticalleHave SSMAgent installed on your instance likethisGive your instance the appropriate IAM permissions for SSM communications through an instance policy (This will allow the instance to communicate with AWS SSM)"ec2messages:*","ssm:updateinstanceinformation","ssm:listassociations"Now write your lambda function using the AWS SDK and it'll work like a charm.
If you're worried about costs, unless you run one mother of a script, you should fall within the free tier as you get 400 GB-seconds of compute time per month.This means you can run a lambda function with 1GB of memory for 400 seconds every month for free.PS: I mentioned EC2 alot, I'm aware you're using lightsail but as it's just a wrapper for EC2 I imagine the same functionality is available, correct me if I'm wrong.

Yes you need to use filters withdescribe_vpcsAPI.The below code will list all VPC's which matches bothNameTag Value and theCIDRblock:import boto3
client = boto3.client('ec2',region_name='us-east-1')
response = client.describe_vpcs(
Filters=[
{
'Name': 'tag:Name',
'Values': [
'<Enter you VPC name here>',
]
},
{
'Name': 'cidr-block-association.cidr-block',
'Values': [
'10.0.0.0/16', #Enter you cidr block here
]
},
]
)
resp = response['Vpcs']
if resp:
print(resp)
else:
print('No vpcs found')CIDRblock is the primary check for VPC. I would suggest to just use theCIDR Filter aloneinstead of clubbing withNameTag as then you can prevent creating VPC with sameCIDR Blocks.
|
I can create a VPC really quick like this:import boto3 as boto
inst = boto.Session(profile_name='myprofile').resource('ec2')
def createVpc(nid,az='us-west-2'):
'''Create the VPC'''
vpc = inst.create_vpc(CidrBlock = '10.'+str(nid)+'.0.0/16')
vpc.create_tags(
Tags = [ { 'Key': 'Name', 'Value': 'VPC-'+nid }, ]
)
vpc.wait_until_available()
createVpc('111')How can I check a VPC with CidrBlock:10.111.0.0/16or a Name:VPC-111already exists before it gets created? I actually wanna do the same check prior to any AWS resource creation but VPC is a start. Best!EDIT:found thatvpcs.filtercan be used to query a given VPC tags; e.g.:fltr = [{'Name':'tag:Name', 'Values':['VPC-'+str(nid)]}]
list(inst.vpcs.filter(Filters=fltr))which returns a list object like this:[ec2.Vpc(id='vpc-43e56b3b')]. A list with length 0 (zero) is a good indication of a non-existent VPC but was wondering if there is more boto/aws way of detecting that.

I would like to know if it's possible to track the deployment status of CodeDeploy by using CLI.
Currently, I'm using Bamboo to trigger the CodeDeploy deployment by CLI using: aws deploy create-deployment ... My Bamboo plan will show green the moment the deployment is triggered instead of checking if the actual deployment is succeeded. Is there a way to let Bamboo/command line verify if the actual deployment was successfully deployed?
Many thanks!

This will probably be the case of your result data set exceeding the limit 1MB:If the total number of scanned items exceeds the maximum data set size
limit of 1 MB, the scan stops and results are returned to the user as
a LastEvaluatedKey value to continue the scan in a subsequent
operation. The results also include the number of items exceeding the
limit. A scan can result in no table data meeting the filter criteria.Check on the result for theLastEvaluatedKeyfield and use it for the next scan operation passing it asExclusiveStartKey
|
In a DynamoDB table, I have an item with the following scheme:{
id: 427,
type: 'page',
...other_data
}When querying on primary index (id), I get the item returned as expected.With ascanoperation inside AWS DynamoDB web app to get all items with typepage, 188 items including this missing item are returned. However, performing this scan operation inside Lambda with the AWS SDK, only 162 items are returned. Part of the code looks like:const params = {
TableName: <my-table-name>,
FilterExpression: '#type = :type',
ExpressionAttributeNames: { '#type': 'type' },
ExpressionAttributeValues: { ':type': 'page' }
};
dynamodb.scan(params, (error, result) => {
if (error) {
console.log('error', error);
} else {
console.log(result.Items); // 162 items
}
});What is missing here?

AWS support solved the problem. Here's their answer:When Beanstalk is deploying an application, it keeps your application files in a "staging" directory while the EB Extensions and Hook Scripts are being processed. Once the pre-deploy scripts have finished, the application is then moved to the "production" directory. The issue you are having is related to the "manage.py" file not being in the expected location when your "01_collectstatic" command is being executed.The staging location for your environment (Python 3.4, Amazon Linux 2017.03) is "/opt/python/ondeck/app".The EB Extension "commands" section is executedbeforethe staging directory is actually created. To run your script once the staging directory has been created, you should use "container_commands". This section is meant for modifying your application after the application has been extracted, but before it has been deployed to the production directory. It will automatically run your command in your staging directory.Can you please try implementing the container_command section and see if it helps resolve your problem? The syntax will look similar to this (but please test it before deploying to production):container_commands:
01_collectstatic:
command: "source /opt/python/run/venv/bin/activate && python manage.py collectstatic --noinput"
|
I am editing my.ebextensions.configfile to run some initialisation commands before deployment. I thought this commands would be run in the same folder of the extracted .zip containing my app. But that's not the case.manage.pyis in the root directory of my zip and if I do the commands:01_collectstatic:
command: "source /opt/python/run/venv/bin/activate && python manage.py collectstatic --noinput"I get aERROR: [Instance: i-085e84b9d1df851c9] Command failed on instance. Return code: 2 Output: python: can't open file 'manage.py': [Errno 2] No such file or directory.I could docommand: "python /opt/python/current/app/manage.py collectstatic --noinput"but that would run themanage.pythat successfully was deployed previously instead of running the one that is being deployed atm.I tried to check what was the working directory of the commands ran by the.configby doingcommand: "pwd"and it seems that pwd is/opt/elasticbeanstalk/eb_infrawhich doesn't contain my app.So I probably need to change$PYTHONPATHto contain the right path, but I don't know which path is it.In thiscommentthe user added the following to his .config file:option_settings:
aws:elasticbeanstalk:application:environment:
DJANGO_SETTINGS_MODULE: myapp.settings
PYTHONPATH: "./src"Because hismanage.pylives inside the src folder within the root of his zip. In my case I would doPYTHONPATH: "."but it's not working.

You need to use topic() function in AWS IoT SQL query. Like this:SELECT * as data, topic() as topic FROM 'desired/+/topic'In this case, your event will include the original message in 'data' field and the used topic in 'topic' field. You can also use integer number as a parameter inside topic() function, to return only sub-group.More data in oficial documentation:http://docs.aws.amazon.com/iot/latest/developerguide/iot-sql-functions.html#iot-function-topic
|
I've got a lambda function called by an IoT rule and I would like to know the topic name from inside this lambda function.So far i'm only able to retrieve the message data from theeventparameter. Nothing in thecontextparameter neither.I haven't found anything in the documentation...Is it even possible ?

Cognito User Pools does not support SRP authentication from .NET SDK. You will not be able to useAuthFlowType.USER_SRP_AUTHwith theInitiateAuthAPI call.If you want to sign-in using a USERNAME and PASSWORD directly, you can look at theAdmin Authentication flowwhich uses theAdminInitiateAuthAPI and ADMIN_NO_SRP_AUTH flow.

I am writing a console POC to demo AWS cognito authentication - App Pool not federated identity, as our API gateway authentication mechanism (not hosted in AWS). This is being written in C#.I have successfully created a user, confirmed them; but now I need to authenticate to retrieve a JWT that an I can pass around and validate downstream.The following codeusing (var client = new AmazonCognitoIdentityProviderClient())
{
var initAuthRequest = new InitiateAuthRequest();
initAuthRequest.AuthParameters.Add("USERNAME", username);
initAuthRequest.AuthParameters.Add("PASSWORD", password);
initAuthRequest.ClientId = clientId;
initAuthRequest.AuthFlow = AuthFlowType.USER_SRP_AUTH;
var response = client.InitiateAuth(initAuthRequest);
WriteLine("auth ok");
}Yields this exception:An unhandled exception of type
'Amazon.CognitoIdentityProvider.Model.InvalidParameterException'
occurred in AWSSDK.Core.dllAdditional information: Missing required parameter SRP_AI cannot find a way in the dotnet sdk of generating an SRP header, can anyone help?Thanks

It depends. API Gateway is mostly used to give temporary access to Lambda functions in environments that are not secure (i.e. browsers, desktop apps, NOT servers).If your environment is secure, as in it runs on an EC2 instance with an IAM role, or another server with secure stored credentials, then feel free to use the SDK and call the Lambda function correctly.If you need to expose your Lambda function to the entire internet, or to authorised users on the web, or to any user that has the potential to grab the access key and secret during transit, then you will want to stick API Gateway in front.With API Gateway you can secure your Lambda functions with API keys, or through other authorisers such as Amazon Cognito so that users need to sign in before they can use the API endpoint. This way they only gain temporary credentials, rather than permanent ones that shouldn't be available to anyone.

In the security groups, assign incoming access to other security groups by specifying a security group ID instead of IP addresses. In the web console, if you start typing "sg" in the source field it will pop up a list of your security groups to choose from. Using a security group ID as the source allows all resources that belong to that security group to have access.Alternatively, if you just want one rule that allows access to every resource in your VPC you would specify your VPC's IP range.
|
I am setting up EMR clusters on demand, and have a windows EC2 server as a workstation, and a linux EC2 server as a secondary server. All in the same VPC. I would like to avoid having to set security group rules each time an instances comes up with a new IP.How would I simply allow any traffic to flow freely between all servers in the same VPC?Thanks!EDIT- Thanks for the replies, I know this is not good practice in production, but we are dealing with some issues tracking down functionality which we believe is caused by ports, this is just a exploration phase, and this will help us. Thanks!

AWS: How to allow all TCP traffic between all instances in same VPC?
|
The problem was the VPC. Even I had the simple VPC with just an public subnet, the beanstalk cannot talk to the instance and so cannot deploy the ECS task definition and docker containers in the instance.By creating two subnets namely public and private and having an NAT instance in public subnet, which becomes the router for the instances in the private subnet. Making the above setup worked for me and I could deploy the ECS task definition successfully to the EC2 instance in the private subnet.
|
I want to deploy an multi-container application in elastic beanstalk. I get the following error.Error 1: The EC2 instances failed to communicate with AWS Elastic
Beanstalk, either because of configuration problems with the VPC or a
failed EC2 instance. Check your VPC configuration and try launching
the environment again.I have set up the VPC with just the public subnet and the security group that allows all traffic both inbound and outbound. I know this is not encouraged for production level deployment, but I have reduced the complexity to find the cause of the error.So, the load balancer and the EC2 instance are inside the same public subnet that is attached with the internet gateway. They both share the same security group allowing all the traffic.Before the above error, I also get another error statingError 2: No ecs task definition (or empty definition file) found in environmentHaving said, I have bundled myDockerrun.aws.jsonfile with.ebextensionsfolderinside the source bundle which the beanstalk uses for deployment.
After all these errors, drilling down to two questions:I cannot understand whyNo ecs task errorappears, when I have packaged mydockerrun.aws.jsonfile containing containerDefinitions?Since there is no ecs task running, there is nothing running in the instance. Is this why beanstalk and ELB cannot communicate to the instance? (Assuming my public subnet and all traffic security group is not a problem)

First create different profiles. Use cli(this works from 1.3.0, won't work in 1.0.0, not sure which you are using since you mention both):serverless config credentials --provider aws --key 1234 --secret 5678 --profile your-profile-nameThen in yourserverless.ymlfile you can set the profile you want use:provider:
name: aws
runtime: nodejs4.3
stage: dev
profile: your-profile-nameIf you want to automatically deploy to different profiles depending on the stage you define variables and reference them in yourserverless.ymlfile.provider:
name: aws
runtime: nodejs4.3
stage: ${opt:stage, self:custom.defaultStage}
profile: ${self:custom.profiles.${self:provider.stage}}
custom:
defaultStage: dev
profiles:
dev: your-profile-name
prod: another-profile-nameOr you can reference your profile name in any other way. Read about variables in serverless-framework. You can get the name of profile to use from another file, from cli or from the same file(like in the example I gave).More about the variables:https://serverless.com/framework/docs/providers/aws/guide/variables/

An ENI (Elastic Network Interface) isnever detachedwhen an instance is Stopped.Every Amazon EC2 instance has aprimary ENIoneth0. This ENI cannot be detached from the instance.It is also possible to createsecondary ENIsand attach them to instances. These stay attached during a Stop and Start, but you can choose to detach it and then attach it to another instance.I notice that your question is very similar to asample questionfor theAWS Solutions Architect - Associateexam:Which of the following will occur when an EC2 instance in a VPC (Virtual Private Cloud) with an associated Elastic IP is stopped and started? (Choose 2 answers)A. The Elastic IP will be dissociated from the instanceB. All data on instance-store devices will be lostC. All data on EBS (Elastic Block Store) devices will be lostD. The ENI (Elastic Network Interface) is detachedE. The underlying host for the instance is changedIn this case, the question is referring to anElastic IPaddress rather than an ENI. Elastic IP addresses remain attached to an instance during Stop and Start if the instance is in a VPC. Earlier-style instances launched underEC2 Classic, however, do have their Elastic IP address detached when Stopped.

Does ENI gets detached when we stop and start the EC2 instance which is connected to the VPC in AWS?

Is the ENI detached from an Amazon EC2 instance when it is stopped and started?

In my experience there are two approaches you could take here.Create an AMI from an instance that has been fully provisioned by ansible. Then use this AMI in your launch configuration.The other option is to use a stock AMI and have ansible provision each new host that is launched by the autoscaling group using cloud-init.The second approach is lacking in many ways compared to the first approach in my opinion. It can take much longer to scale up when ansible needs to run every time. You also risk something going wrong during the provisioning, preventing the instance from joining the group, causing further delays. You also run the risk of there being drift between instances (depending on what you are having ansible do and if anything external changes between Autoscaling events).If you decide to create a fully provisioned AMI for your ASG you can do it manually from an instance you already have created. However if you expect to want to rebuild the image regularly you may want to look into a tool likepackerto help you create images in an automated way.

update-deploymentis used to update the metadata of an existing deployment. For example, to update the description of a deployment:aws apigateway update-deployment \

If you're now loading a font from a different domain, most browsers will apply a Cross-Origin Resource Sharing limitation - that is to say, most browsers won't load a file from a different domain without a CORS Policy.You can whitelist the font to be loaded by any-domain by first having your webserver that CloudFront is serving from, send the following response header:Access-Control-Allow-Origin: "*"Secondly, you need to go into your CloudFront configuration and whitelist the "Access-Control-Allow-Origin" header to be passed from your webserver, to the end-user.More reading on CORS can be found here:http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/header-caching.htmlhttp://www.html5rocks.com/en/tutorials/cors/

I have two servers (with my app on it) already running.. created from Ubuntu AMI.
While using auto-scaling it starts new instances using an AMI.Can I use auto-scaling to ONLY stop instance (not terminate; so that I don’t need an AMI when starting server in future); and later start instance (old instance which I had stopped) whenever CPU increases above x% !If not auto-scaling; I am ok with any other solution also. I can stop the instance with Cloudwatch, but how do I restart it?

This use case is almost the textbook example for AWS Lambda. If you look atthe AWS Lambda image resize example, all you need to do is remove code that tests for the image type and actually does the resize- it's designed to download, transform, then upload the object to a new S3 bucket.Also, you may be able to do this even more easily (and cheaply) withS3 cross-region replication, but thatrequiresthe buckets be in different regions (thanks @William-Gaul).So, it depends on your precise use case.

TheHttpUtility.UrlEncodemethod encodes spaces as+which is acceptable according to the standards. However, for some reason I don't understand, this causes problems with the Signed URLs and content disposition. The other encoding of space as%20works correctly. So after encoding, replace the+with%20. The working version is:var contentDisposition = HttpUtility.UrlEncode("attachment;filename=My File.txt");
contentDisposition = contentDisposition.Replace("+", "%20");
var key = "example.txt?response-content-disposition="+contentDisposition;
return AmazonCloudFrontUrlSigner.GetCannedSignedURL(

The signed URLs I generate using the .NET AWS SDKAmazonCloudFrontUrlSigner.GetCannedSignedURLmethodwork correctly when the content disposition filename doesn't contain spaces. However, if the filename contains spaces, I get access denied. So, something like the code below will generate a URL that gives access denied.var contentDisposition = HttpUtility.UrlEncode("attachment;filename=My File.txt");
var key = "example.txt?response-content-disposition="+contentDisposition;
return AmazonCloudFrontUrlSigner.GetCannedSignedURL(
AmazonCloudFrontUrlSigner.Protocol.https,

I read thecode of theAmazonCloudFrontUrlSignerclass. I've also tried an number of combinations ofUrlEncodelike not encoding, encoding only the filename portion and even not encoding but replacing with the encoded version after the signed URL is generated. All of those either give access denied or an error that the signature doesn't match the url.

Two common causes of connection failures to a new DB instance are:The DB instance was created using a security group that does not authorize connections from the device or Amazon EC2 instance where the MySQL application or utility is running. If the DB instance was created in a VPC, it must have a VPC security group that authorizes the connections. If the DB instance was created outside of a VPC, it must have a DB security group that authorizes the connections.The DB instance was created using the default port of 3306, and your company has firewall rules blocking connections to that port from devices in your company network. To fix this failure, recreate the instance with a different port.You can use SSL encryption on connections to an Amazon RDS MySQL DB instance.

- name: do some fun stuff on the new instances hereAlternatively if you have consistently tagged all your servers (and with multiple tags if you also have to differentiate between production and development; and you are also using the ec2.py as the dynamic inventory script; and you are running this against all the servers in a second playbook run, then you can easily do something like the following:- hosts: tag_Name_cassandra
tasks:
- name: run your cassandra specific tasks herePersonally I use a mode tag (tag_mode_production vs tag_mode_development) as well in the above and force Ansible to only run on servers of a specific type (in your case Name=cassandra) in a specific mode (development). This looks like the following:- hosts: tag_Name_cassandra:&tag_mode_developmentJust make sure you specify the tag name and value correctly - it is case sensitive...
|
This is probably obvious, but how do you execute an operation against a set of servers in Ansible (this is with the EC2 plugin)?I can create my instances:---
- hosts: 127.0.0.1
connection: local
- name: Launch instances
local_action:
module: ec2
region: us-west-1
group: cassandra
keypair: cassandra
instance_type: t2.micro
image: ami-4b6f650e
count: 1
wait: yes
register: cass_ec2And I can put the instances into a tag:- name: Add tag to instances
local_action: ec2_tag resource={{ item.id }} region=us-west-1 state=present
with_items: cass_ec2.instances
args:
tags:
Name: cassandraNow, let's say I want to run an operation on each server:# This does not work - It runs the command on localhost
- name: TEST - touch file
file: path=/test.txt state=touch
with_items: cass_ec2.instancesHow to run the command against the remote instances just created?

It's a problem of correctly escaping the quotes in fact.Reason is :\"inside a CloudFormation string is escaped as"(double-quote).For example,"hello \"me\""gives you :hello "me"In your line, what you really feed to bash is :echo " accessKeyId:XXXXX" >> /home/ubuntu/myfile.jsonConsidering bash use of quotes, you get the stringaccessKeyId:XXXXXinside your/home/ubuntu/myfile.jsonTo solve your problem, I would recommend using:{"Fn::Join": ["", ["echo '\"accessKeyId\":\"", {"Ref": "AccessKeyId"}, "\"' >> /home/ubuntu/myfile.json"] ] },which is escaped asecho '"accessKeyId":"XXXXX"' >> /home/ubuntu/myfile.json(hard to read : the whole string used by echo is inside single-quotes).I'm not able to try it now, but it should do the trick.

After much research and frustration, I'm not quite getting the output I'm hoping for.The desired output into a file would be for example"accessKeyId":"UIIUHO]SOMEKEY[SHPIUIUHIU"But what I'm getting isaccessKeyId:UIIUHO]SOMEKEY[SHPIUIUHIUBelow is the line in an AWS Cloudformation template{"Fn::Join": ["", ["echo \" accessKeyId:", {"Ref": "AccessKeyId"}, "\" >> /home/ubuntu/myfile.json"] ] },I've tried adding \" with in the echo statement but no quotes are output. Can someone show how to produce the desired output above?

No, there is no method for identifying matching AMIs across different regions.Some background...AnAmazon Machine Image (AMI)contains a disk image that is used to boot an Amazon EC2 instance. It is created by using theCreate Imagecommand on an existing Amazon EC2 instance, and can also be created from an EBS Snapshot (Linux only).Each AMI receives a unique IDin the formami-1234abcd.AMIs exist in only one AWS region.When an AMI is copied between regions, it receives a new AMI ID. This means that the "same" image will appear with a different AMI ID in each region.When an AMI is copied between regions, it will retain its name and description, but this is not necessarily unique, so it cannot be used to definitively match AMIs between regions.AMI creators will often supply a list of matching AMI IDs across regions, for example:Amazon Linux AMI IDs
|
as title, while I create CFN template, I always check EC2 console for AMI id in different regions.these ids belong to the same spec image,
ex: all of them are "ubuntu 12.04 64 bit", but in various regionsis there any quick method to check this messages?thanks a lot!

You can use a site like CloudWatch:http://www.cloudwatch.in/. It measures EC2, SimpleDB, SQS and SNS services latency from your browser.Edit:CloudWatch doesn't contain the new eu-central-1 location, however I submitted a PR to add it. I will update this answer when it gets accepted.Edit 2:PR has been accepted, the list on the site now contains Frankfurt.
|
How can I check which Amazon region is has the lowest latency from my present location? Is there some script that pings servers on all of them several times and calculates the average latency?Preferably a solution that also compares latency to the newly launched Frankfurt (eu-central-1) region.

Thanks for your sample code, Alex Chan. I needed this functionality too, so I decided to write more completeS3FileUploadFieldandS3ImageUploadFieldclasses, based on your code and various other snippets.You can find my code at:https://github.com/Jaza/flask-admin-s3-uploadAlso up on pypi, so you can install with:pip install flask-admin-s3-uploadI've documentated a basic usage example in the readme (can see it on the github project page). Hope this helps, for anyone else who needs S3 file uploads in flask-admin.

I am using Flask-Admin and is very happy with it. However, the sample in Flask-Admin only provides to upload the image to static folder. Is it possible to upload it to S3 directly with Flask-Admin? Thanks.Regards

I have a workflow which takes a file in an S3 bucket and does a lot of processing and further requests based on the file contents. Currently, clients have to trigger the workflow manually after uploading the file. This seems to be a pretty common use case for me, so is there any way to trigger the workflow as soon as the file is uploaded?I imagine there should be an SNS notification in between, but is there any way to send the notification directly to the SWF, without having a service consuming them and starting the workflow?

There is not a way to update the backend authentication via the management console, but you can use the command line interface to do this.The process is documented athttp://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/config-backend-auth.html, in the "Using the Command Line Interface" section.The link above has the necessary details, but conceptually the steps are:Obtain your backend server's public key.Useelb-create-lb-policyto create a newPublicKeyPolicyTypepolicy for that public key.Useelb-create-lb-policyto create a newBackendServerAuthenticationPolicyTypebased on the new public key policy you just created. (You can also include previously existing public key policies if your load balancer has instances that still have old certificates; simply add more--attributearguments for those public key policies. You can see existing policies for the load balancer with theelb-describe-lb-policiescommand.)Useelb-set-lb-policyto tell your load balancer to use your new backend server authentication policy for the desired port.

In my case, using m1.small, I followedthis docto create a custom AMI.I think the reason it kept booting forever is the opsworks-agent files are still there. See step 4 underTo create a custom AMI from an AWS OpsWorks instance, you'd need to stop agent and delete it's files.The complete cycle improved from ~25 minutes down to ~10 minutes. By the ~11th minute, it's on LB health checks stage.Hope that helps.
|
I like AWS OpsWorks but one big drawback I am facing now is boot time: nodes are booting super slowly.In my case, for a t1.micro instance, it takes like 10 minutes before my cookbook can start running (although from EC2 console view, the instance should be ready after about 2 minutes: it can be accessed via SSH after this short period). You can also refer tothis topic.I tried using custom AMI but ran into another problem: the node kept booting forever. But that might be my fault while creating the AMI.Back to the original question, how can I improve this boot time of OpsWorks nodes?

Like @chris said, there is no way to change the key associated with the instance. You will need to launch a new one with the new key assigned to it.BUT If SSH access is what you need, don't bother trying to change or update the key associated with the instance. It has been a while since I stopped assigning keys to instances over allowing OpsWorks manage user access in the permissions section.This gives you great flexibility because you don't need to share keys amongst users or start new instances every time you need to change or set a new SSH key. You can add or remove users any time, and you control who has SSH and/or Sudo access.To start either grant one of your users access to OpsWorks or import IAM users:After access has been granted, ask the user to add their own public key in the "My Settings" > Edit page:If you gave this user access to SSH all you have to do is wait for the recipes to finish running and the user will be able to connect to the instance like this:$ ssh -i ~/.ssh/[your-key-file] [user-name]@[instance-ip-address]Note that any time you make changes to the permissions or settings section, recipes will be run in your instances updating the user access.For more information on how to grant user permissions in OpsWorks see theAWS Documentation

Okay, we were able to figure this out on our own. The problem with my example above is that I'm using a list instead of a set. The value of a multi-value attribute MUST be a set.For example, this works:Item(Table('test'), data={'id': '123', 'content': 'test', 'list': set([1,2,3,4])}).save()
|
After scouring the documentation and various tutorials, I cannot figure out how to set or update an attribute on a dynamo Item that is a multi-valued data type (number or string set). I'm using boto (boto.dynamodb2, to be specific -- not boto.dynamodb).Trying something like this (where 'id' is the hash key):Item(Table('test'), data={'id': '123', 'content': 'test', 'list': [1,2,3,4]}).save()Results in this error:TypeError: Unsupported type "<type 'list'>" for value "[1, 2, 3, 4]"I feel like this must be possible in boto.dynamodb2, but it's odd that I can't find any examples of people doing this. (Everyone is just setting number or string attributes, not number set or string set attributes.)Any insight on this topic and how I might get this to work with boto would be very much appreciated! I'm guessing I'm overlooking something simple. Thanks!

In my php script that PUT files to S3 using AWK SDK for PHP, I had to add in the meta data, as shown below, which did the trick:$response = $s3->create_object('bucketname', 'mountpoint/'.$filename, array(
'body' => $json_data,
'contentType' => 'application/json',
'acl' => AmazonS3::ACL_PUBLIC,
'meta' => array(
'mode' => '33188', // x-amz-meta-mode
)
));The mode "33188" defined the permissions "rw-r--r--" instead of "---------" in S3 bucket (but reflected only in the EC2 mounted folder), which was later inherited by the EC2 mounted drive.Hope this helps someone. Let me know!

Using S3FS and FUSE to mount a S3 bucket to an AWS EC2 instance, I encountered a problem whereby my S3 files are being updated, but the new files doesn't adopt the proper permission.The ACL rights that the new files had were "---------" instead of "rw-r--r--". I've ensured that the bucket is mounted properly by:sudo /usr/bin/s3fs -o allow_other -o default_acl="public-read" [bucketname] [mountpoint]and creating an automount in /etc/fstab:s3fs#[bucketname] [mountpoint] fuse defaults,noatime,allow_other,uid=1000,gid=1000,use_cache=/tmp,default_acl=public-read 0 0and password file in /etc/passwd-s3fs with the right permissions.My setup is Ubuntu 13.04, PHP5, AWS SDK.After 2 days of experimenting, I've found a solution (for php) in the provided answer below.

Given these parameters:An Ubuntu instance running anywhere(any region and any availability zone in that region)Only the AWS PHP SDK2 installed on the instance (no other EC2 Command line tools, etc.)CURL and WGET availableWhat is the most elegant way for an instance script to explicitly determine what Region it is running in?* **Instance ID:** wget -q -O - http://169.254.169.254/latest/meta-data/instance-id
* **Availability Zone:** wget -q -O - http://169.254.169.254/latest/meta-data/placement/availability-zoneThemeta-data does notcurrently provide this information.We are aware that currently, the trailing character can be stripped off the availability zone in order to naively determine the Region, however, there isno guaranteethat Amazon will not change that in the future.The ultimate goal is that our cron jobs and other custom services can figure out who and where they are, so that they can interact with other services and instances appropriately.

I have fixed this issue:You have to make sure that you already have created a bucket with the same name; in this case, the name of the bucket would be 'myBucket'.s3.createBucket({Bucket: 'myBucket'}, function() {
var params = {Bucket: 'myBucket', Key: 'myKey', Body: 'Hello!'};Once you created the bucket, go to properties and see what region it is using - add this into:aws.config.update({
accessKeyId: 'KEY',
secretAccessKey: 'SECRET',
region: 'eu-west-1'
})Now it should work! Best wishes

I'm having some issues with the EC2 bit of Boto (Boto v2.8.0, Python v2.6.7).The first command returns a list of S3 Buckets - all good!

S3FS uses special 'hidden' zero byte files to represent directories, because S3 doesn't really support directories. If you try a mkdir on your mounted s3fs bucket then use the AWS file browser you should see this in action. If your S3 bucket contains a directory structure that was not created by S3FS then S3FS won't recognise that structure. S3FS only works well with buckets that are only ever manipulated using S3FS.After trying to use s3fs for a project I was working on I concluded that it was better to be exposed directly to the limitaions of S3, rather than using something which attempts to hide those limitations.
|
I've been trying to set up Amazon S3 as a backup service for my files. I'd like to use the service by mounting it as a drive on my ubuntu install, and thes3fs projectis supposed to make that possible. But I'm having some trouble with it. I believe I have successfully installed fuse and s3fs. When I mount a drive, I get no errors; however, when I then enter the directory and issue the 'ls' command, nothing happens. If I create a test file with a command like:touch file.testthe file shows up in the aws console. But I am unable to either see the files that are already present in the bucket or navigate into subdirectories using the 'cd' command. I've done a bit of sniffing around in the projects google forum, and I think I have discovered that s3fs cannot see any contents of an s3 bucketunlessthose files or directories have been created using s3fs. Has anyone else encountered this problem? Is this really the way this project has been designed? Is this a bug? Or is there a way around this problem?

I'm relatively new to using AWS and am stuck on what I believe should be a basic task. I'm using the PHP SDK version 2 to retrieve files from one of my buckets to a temp directory on my server. According to thedocumentationI can usegetObjectto do this. Using the following code snippets I am able to retrieve the file but am having trouble saving the actual contents to the temp directory.#1$result = $s3->getObject(array(
"Bucket" => $s3Bucket,
"Key" => $s3Path,
"ResponseContentType" => "image/jpeg",
"SaveAs" => EntityBody::factory(fopen($saveFile, "wb"))
));#2$result = $s3->getObject(array(
"Bucket" => $s3Bucket,
"Key" => $s3Path,
"ResponseContentType" => "image/jpeg",
"SaveAs" => fopen($saveFile, "wb")
));Both of these request are successful in the sense that they return the object but I am still getting a tmp file of 0 bytes. Any insight into this is greatly appriciated.Thanks!

Take a look atGoogle App Engine. One big advantage it provides is unlimited scaling and geo-diversity right out of the box. So you deploy your app and it magically grows and shrinks to accomodate database demand. Re: the database itself, you have two options:Google Cloud SQL, which is a MySQL database engine in the cloud, or theApp Engine Datastore, which is a scalable NoSQL database built into App Engine.If you require MySQL, e.g. because you've got existing code you need to port, then Cloud SQL would be your best bet, but if you have the flexibility to use a NoSQL database the Datastore is extremely simple and very powerful (like App Engine, it automatically scales from day one). You can also use a new feature calledGoogle Cloud Endpoints, to provide a scalable API from your iOS clients to your App Engine app.Another nice feature of the Google Cloud: if you need to do analysis on your data, you can use theApp Engine MapReduce API,Google BigQuery, orFusion Tables.

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened,visit the help center.Closed11 years ago.I'm trying to setup a database for an iOS app I'm building to be used amongst a lot of users. I've been looking into the services that Google Cloud & AWS offers, and I'm having difficulty figuring out both what services I would need to use exactly, and how much each would cost.As of now, I just want somewhere to host the data that will eventually be in MySQL databases that I'm going to use for the app.A quick 101 on how this stuff is supposed to work would be great!

I have a job running using Hadoop 0.20 on 32 spot instances. It has been running for 9 hours with no errors. It has processed 3800 tasks during that time, but I have noticed that just two tasks appear to be stuck and have been running alone for a couple of hours (apparently responding because they don't time out). The tasks don't typically take more than 15 minutes. I don't want to lose all the work that's already been done, because it costs me a lot of money. I would really just like to kill those two tasks and have Hadoop either reassign them or just count them as failed. Until they stop, I cannot get the reduce results from the other 3798 maps!But I can't figure out how to do that. I have considered trying to figure out which instances are running the tasks and then terminate those instances, butI don't know how to figure out which instances are the culpritsI am afraid it will have unintended effects.How do I just kill individual map tasks?

The process will shut down when you logout if it's running in the foreground or if it tries to write to stdout and the terminal it's outputting to no longer exists. Try starting the server withnohup python startTornado.py &The nohup command redirects output to a file, and the & at the end runs the command in the background. Alternatively, you can use the screen utility which allows you to detach a terminal and reattach it in a different ssh session (see the screen man page for details).

I'm using SSH to remotely launch Tornado on Amazon Web Service. It works fine when I launch it by:python startTornado.pyHowever, after my SSH session times out or terminated, the Tornado server is also stopped immediately, so I can't access the webpage anymore. I did quite some search but couldn't find an answer on Google.How can I keep Tornado and the site running after my SSH session terminated?

You can configure the framework bundle to do this:http://symfony.com/doc/2.0/reference/configuration/framework.html#trust-proxy-headersframework:

I'm running a Symfony2 web application on AWS, and am using an Elastic Load Balancer.In a controller method, I need to do the following to get the IP of a user requesting a web page:$request->trustProxyData();
$clientIp = $request->getClientIp(True);Does this present any security risks? I'm not using the client IP for privilege escalation, I'm just logging it.Is there some way to forcetrustProxyData()always, or otherwise reconfigure$request->getClientIp()toDWIM? My app will always be behind a load balancer (except while I do development on my desktop).Related:http://fabien.potencier.org/article/51/create-your-own-framework-on-top-of-the-symfony2-components-part-2(but it doesn't say if there's some global config so I don't have to calltrustProxyData()everywhere).

Amazon provides a way to do this directly using the S3 api.You can use theprefixoption when calling listing S3 objects to only return objects that begin with the prefix. eg using the AWS SDK for PHP:// Instantiate the class
$s3 = new AmazonS3();
$response = $s3->list_objects('my-bucket', array(
'prefix' => '000001-'
));
// Success?
var_dump($response->isOK());
var_dump(count($response->body->Contents))You might also find thedelimiteroption useful - you could use that to get a list of all the unique 6 digit hashes.

Assume 200,000 images in a flat Amazon S3 bucket.The bucket looks something like this:000000-1.jpg
000000-2.jpg

000000-4.jpg
000001-1.jpg
000001-2.jpg
000002-1.jpg
...
ZZZZZZ-9.jpg
ZZZZZZ-10.jpg(a 6 digit hash followed by a count, followed by the extension)If I need all files matching000001-*.jpg, what's the most efficient way to get that?In PHP I'd userglob($path,'{000001-*.jpg}',GLOB_BRACE)to get an array of matches, but I don't think that works remotely.I can get a list of all files in the bucket, then find matches in the array, but that seems like an expensive request.What do you recommend?

UpdateAs alreadypointed outby frisky (+1), AWS has meanwhile releasedDynamoDB Local for Desktop Development- please seeDynamoDB Localfor details, in particular sectionDifferences Between DynamoDB Local and DynamoDB.As of recently, this initial offering is also fully integrated in theAWS Toolkit for Eclipseand theAWS Toolkit for Visual Studio, see the following introductory blog posts:DynamoDB Local Test Tool Integration for EclipseAmazon DynamoDB Local Integration with AWS Toolkit for Visual StudioOriginal AnswerYou neither need nor can install anything local - please see the first paragraph of theAmazon DynamoDBproduct page for details, e.g:Amazon DynamoDB is afully managed NoSQL database servicethat
provides fast and predictable
performance with seamless scalability.
[...] customers can launch
a new Amazon DynamoDB database table, scale up or down their request
capacity for the table without downtime or performance degradation [...].
Amazon DynamoDB enables customers tooffload the administrative
burdens of operating and scaling distributed databasesto AWS, so they
don’t have to worry about hardware provisioning, setup and
configuration, replication, software patching, or cluster scaling.[emphasis mine]Please note that you will likely install one of the AWS SDKs (e.g.the AWS SDK for Javaor theAWS SDK for .NET) on your local development system though, if you are planning to work with DynamoDB, they offer various otherDeveloper Toolsas well.

Since I'm not familiar with cloud services yet, I must ask.If I'll use DynamoDB from AWS, would it needed to be installed on local? Or is everything handled on the server-side?

Can Amazon DynamoDB be used without local database?

Yeah, the config file format and the service constructors changed slightly in version 1.5. They mentioned this as a backwards-incompatible change in the release notes.http://aws.amazon.com/releasenotes/PHP/3719565440874916

I can't speak to IMDB's specific implementation, but I have implemented a similar solution on Amazon EC2 and S3 in the past. Here is an overview of my implementation:All master (full-sized) images stored on S3, but NOT publicly accessible.All image src urls point to an EC2 web server.Smaller (thumbnail) versions of images also stored on S3 with a naming convention that identifies their size AND aspect ration:"myimage1_s200.jpg" is a square version of "myimage1.jpg" that has been resized as a 200x200 square."myimage1_h100.jpg" has been resized to a maximum height of 100 (with a variable width that conforms to the original aspect ratio).When the EC2 server receives a request for a specific image size: it checks to see if that size already exists, and if so it returns the existing image to the requester.When the EC2 server receives a request for an image size that DOES NOT exist: it retrieves a copy of the next larger size version of the same image and resizes it and returns the new image to the requester, AND ALSO saves a copy to S3 for future use.Performance Notes:Pointing image src's directly to previously resized images on S3 is a lot faster if you know they exist!Resizing the next larger version of the image vs always going back to the original is a LOT faster under load!
|
I've been researching CDNs and image thumbnail generation and I was impressed with how IMDb does its image manipulation. Here's an example of a thumbnail version:http://ia.media-imdb.com/images/M/MV5BMTc0MzU5ODQ5OF5BMl5BanBnXkFtZTYwODIwODk1._V1._SY98_CR1,0,67,98_.jpgAnd here's a tweaked version that plays with size and cropping:http://ia.media-imdb.com/images/M/MV5BMTc0MzU5ODQ5OF5BMl5BanBnXkFtZTYwODIwODk1._V1._SY400_CR10,40,213,314_.jpgIt seems pretty straight forward where everything from '.V1._...' on is used to determine how to manipulate the image. This is all done impressibly fast and I decided to find an existing solution that mimics this functionality.I was able to find plenty of solutions in image re-sizing and I did find the Google App Engine's page on Transforming Images in Java. However, I don't think Amazon's IMDb is using Google to serve its images and since all my images are on Amazon's S3, I don't think I can use that solution.After four hours of online searching, I decided to ask the intelligent crowd here.Further context: I am building a web application on Amazon's Elastic Beanstalk and I'm thinking of having a separate server (perhaps another Beanstalk) to handle the images...similar to what IMDb is doing.Thanks in advance for your insight.

The AMI represents the launchable machine configuration - it does NOT actually contain any of the machine's data, just references to it. An AMI can get its disk image either from S3 or (in your case) an EBS snapshot.The EBS Volume is associated with arunninginstance. It's basically a read-write disk image. When you terminate the instance, the volume will automatically be destroyed (this may take a few minutes, note).The snapshot is a frozen image of the EBS volume at the point in time when you created the AMI. Snapshots can be associated with AMIs, but not all snapshots are part of an AMI - you can create them manually too.More information on EBS-backed AMIs can be found inthe user's guide.It is important to have a good grasp on these concepts, so I would recommend giving the entire users guide a good read-over before going any further.If you want to delete all data associated with an AMI, you will have to use theDescribeImageAttributeAPI call on the AMI's blockDeviceMapping attribute to find the snapshot ID; then delete the AMI and snapshot, in that order.
|
I usedCreateImageRequestto take a snapshot of a running EC2 machine. When I log into the EC2 console I see the following:AMI - An image that I can launchVolume - I believe that this is the disk image?Snapshot - Another entry related to the snapshot?Can anyone explain the difference in usage of each of these? For example, is there any way to create a 'snapshot' without also having an associated 'AMI', and in that case how do I launch an EBS-backed copy of this snapshot?Finally, is there a simple API to delete an AMI and all associated data (snapshot, volume and AMI). It turns out that our scripts only store the AMI identifier, and not the rest of the data, and so it seems that that's only enough information to just Deregister an image.

It depends on how long you need to run your instance. A small linux instance will cost 8.5 cents per hour. If you spend a week at Pycon and have your instance running the entire week, it would cost $14.28 for the week. You probably won't need it while you are asleep, so you can turn it off when you are done each day. If you only need it for an hour it will cost you 8.5 cents.Here's more details on the pricing if you need a bigger server or you need a windows server instead:http://aws.amazon.com/ec2/#pricing
|
I'm about to go to Pycon, and while I have my hosting at Webfaction one of the tutorials (JKM) asks for students to have AWS instances. I've been trying to figure out what some minimum charge examples might look like? I'll have a lamp server with Django and a requisite amount of storage but next to no traffic.Anyone have some guidance/advice? My Google searches and look here did not turn up much useful info.

As an experiment I want to work a bit with AWS. How much might I expect to pay?
|
In addition, there'sCloud42, but while all of these tools, along with Amazon's new official Java API interface are quite nice, none of them (except Rightscale, which is awesome, but very incompatible with what I'm doing, sadly) have any sort of functionality remotely close to properly managing an application launch on the cloud.I suspect thatNimbusandOpenNebulaare actually tools closer to what I was asking about - proper automated system management, rather than just access for manual machine management, however I have not had a proper chance to investigate either of these.For my purposes we developed our own in house tool using theTypicalibrary and several other tools, that allowed us to give machines abstract names and launch, configure, and issue commands to them via their names rather than instance id's or private dns's. Might be released open source, but that's not my decision unfortunately. I'll update this if it is.
|
As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references, or expertise, but this question will likely solicit debate, arguments, polling, or extended discussion. If you feel that this question can be improved and possibly reopened,visit the help centerfor guidance.Closed10 years ago.I'm looking to manage a system (or preferably multiple systems) of machines on EC2, and at present the only way I can see doing that in a reasonable way is to extend theTypicalibrary and build a control panel that launches, configures, and checks in on machines for me.I don't expect there to be any prefabricated solutions to exactly my problem out there, but I'm wondering if there are any good tools for managing EC2 instances out there? Preferably in Java, but it'll more than likely be easier to learn a new language than to implement a seriously powerful control panel.And yes, I know about Elasticfox - it's a wonderful tool, but not nearly powerful enough for what I'm looking for.

Update:EC2 now supports "tags" for categorising instances.http://docs.amazonwebservices.com/AWSEC2/latest/UserGuide/index.html?Using_Tags.htmlI've always used security groups for categorising. I don't see anything wrong with using them!Groups not only allow categorising, they also allow different firewall rules. You can also have more than one group per instance, e.g. "production", "database"Reference:http://docs.amazonwebservices.com/AWSEC2/2008-12-01/DeveloperGuide/index.html?ApiReference-SOAP-RunInstances.html
|
Is there a way to distinguish between sets ofEC2instances?My use case is that I have a bunch of web tier machines and a bunch of search tier machines; currently the only way to track what each instance is doing is in a roll-your-own asset directory, like LDAP or a database.Ideally, I'd like to be able to determine theroleof a machine from the metadata available from the AWS APIs.Currently, the only approach I've come up with is to have different machine roles in different security groups (even if it's not strictly required). Is there a better way?

The bug report for this issue ishereThe underlying cause is that the AWS cli shipped a breaking change in a minor version release. You can see thishereI'm assuming here you're using thepulumi-ekspackage in order to provision an EKS cluster greater thanv1.22. The EKS package uses a resource provider to configure some EKS resources like theaws-authconfig map, and this isn't the same transient kubeconfig you're referring to in~/.kube/configIn order to fix this, you need to do the following:Ensure youraws-cliversion is greater than1.24.0or2.7.0Ensure you've updated yourpulumi-ekspackage in your language SDK package manager to greater than0.40.0. This will mean also updated the provider in your existing stack.Ensure you have the version ofkubectlinstalled locally that matches your cluster version that has been provisioned

I get the following error message whenever I run a pulumi command. I verified and my kubeconfig file isapiVersion: v1I updatedclient.authentication.k8s.io/v1alpha1toclient.authentication.k8s.io/v1beta1and still have the issue, what could be the reason for this error message?Kubeconfig user entry is using deprecated API version client.authentication.k8s.io/v1alpha1.

If your app creates a connection pool of 100, that's the number of database connections it will try to open. It must be lower than your MySQL connection limit.Typically connection pools openallthe connections for the pool, so they are ready when a client calls the http API. The connections might normally be running no SQL queries, if there are not many clients using the API at a given moment. The database connections are nevertheless connected.Sort of like when yousshto a remote linux server but you just sit there at a shell prompt for a while before running any command. You're still connected.You asked if adb.t2.microinstance was not recommended for production. Yes, I would agree with that. It's tempting to use the smallest instance possible to save money, but adb.t2.microis too small for anything but light testing, in my opinion.In fact, I would not useanyt2instance for production, regardless of size. Thet2type uses "burstable" performance. This means it can provide only brief periods of good performance. Once the instance depletes its performance credits, they recharge slowly, and while they recharge, the performance of that instance is very low. This is okay for testing, but not for production, if you expect to provide consistent performance at any time.

I have anRDS instancehosting a mySQL database. Instance size isdb.t2.microI also have anExpressJSbackend connecting to the mySQLRDS instancevia a connection pool:Additionally i have a mobile app, the client, feeding off theExpressJSAPI.The issue i'm facing is, either via the mobile app or via Postman, there are times where i get a 'Too many connections' error and therefore several requests fail:On theRDS instance. On current activity i sometimes get 65 connections, showing it's reaching the limit. What i need clarity on is:When 200 mobile app instances connect to the API, to theRDS instance, does it register as 200 connections or 1 connection fromExpressJS?Is it normal to be reaching the RDS instance 65 connection limit?Is this just a matter of me usingdb.t2.microinstance size which is not recommended for prod? Will upgrading the instance size resolve this issue?Is there something i'm doing wrong with my requests?Thank you and your feedback is appreciated.

I think you have to take into account that other users may haveAllowin their policies, so the approach here should be to deny access to any users not being the user you want it to be. There is a detailed explanation in the AWS docs [1], but for the sake of brevity, I think the terraform code should look like the following:data "aws_iam_policy_document" "vulnerability-scans" {
statement {
sid = "AllExceptUser"
effect = "Deny"
principals {
type = "AWS"
identifiers = ["*"]
}
actions = [

]
condition {
test = "StringNotLike"
variable = "aws:userId"
values = [
aws_iam_user.circleci.arn
]
}
}
}Even though the reference URL says it is for an IAM role, the same applies for a user. TheStringNotLikecondition operator has more detailed explanation in [2].[1]https://aws.amazon.com/blogs/security/how-to-restrict-amazon-s3-bucket-access-to-a-specific-iam-role/[2]https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_condition_operators.html#Conditions_String

After a lot of frustration and waiting I solved this by:Deleting the hosted zone associated with the domain.Creating a new hosted zone for the domain. Route 53 auto-generates an NS record with 4 pre-filled name server addressesGoing to Domains > Registered Domains > (domain) > Add or edit name servers. Deleting the four name servers there and replacing them with the four that Route 53 gave me in step 2 (without the periods at the end).Within a few min the domain started pointing to the IP I specified and was picked up by a bunch of DNS servers as measured byhttps://dnschecker.org/Hope this helps someone, someday

I registered a domain name on AWS Route 53, then deleted the generated hosted zone that they automatically generated for the domain and replaced it with this one:The values in the NS record match the name servers of the registered domainI haven't modified these settings for almost 72 hours, and the registered domain name still doesn't point to the IP I specified. Any idea why? It all looks correct to me.

Yes, you canspecify sensitive datato be automatically fetched and injected to your container.You do this usingsecretsparameter of your Task Definition:Amazon ECS enables you toinjectsensitive data into your containers by storing your sensitive data in eitherAWS Secrets Managersecrets or AWS Systems Manager Parameter Store parameters and then referencing them in your container definition.

We have a node application running in ECS and have local credentials in the .env file but we don't want to load credentials from the .env file due to security. Rather, we want those to be injected by AWS into the container environment. We don't want to use AWS SDK to fetch secrets in a node application. Is there any way to inject all secrets into the container environment?

The Route53 record provides you the option to choose the target Load Balancer to get pointed to.

I had the same issue and I figured out the reason it was happening. When you mention yourDSNin theAmazon Athena (Beta), the next thing it will ask is your login (which has two options).Do not take the 2nd option. Pick the first option where the all setting are pulled from your DSN settings, which you did to setup your datasource.Now if you once did it wrong, It won't ask you again the same things to fix it. Create a new powerbi file and do the steps.

Short answerYes, but don't do it. There are other solutions.Explanation why you shouldn't do itYou can use a lambda in between your containers and API gw but using a lambda as a 'middleware' is an antipattern, you will have to pay double by making your lambda wait on your microservices response.Other solutionsIf you want to handle authentication or check headers and cookies you should use a lambda authorizer.For your use-case you can make use of an application loadbalancer. That can do path redirects to different target groups.https://aws.amazon.com/premiumsupport/knowledge-center/elb-achieve-path-based-routing-alb/It might make sense in having a library that is shared by the different microservices that does the early response or request checking.Not sure what is your real goal and use case but if you elaborate more on what you'd like to achieve, I might can help.

However before to do proxy it would be nice to have lambda which may check requests and make a decision if allowed to make proxy or it's better to make a response imidiatly, so, in another word, I would like to have AWS lambda as middleware. Is it possible to do?

No, there is no way to set one initially, your process is the one the officialaws docsalso recommend:When you create an account, AWS Organizations initially assigns a long (64 characters), complex, randomly generated password to the root user. You can't retrieve this initial password. To access the account as the root user for the first time, you must go through the process for password recovery. For more information, seeAccessing a member account as the root user.It may however not be necessary to login as root anyway sinceAWS Organizations automatically creates an AWS Identity and Access Management (IAM) role in the member account. This role enables IAM users in the management account who assume the role to exercise full administrative control over the member account.And generally setting / configuring passwords in terraform is risky because the password would show up in the state files and in the version control system you hopefully check your terraform files into.

I have a Terraform script that allows me to create new AWS accounts inside organizations usingaws_organization_accountresource. I do not have any problem when creating that new account but I am wondering what is the initial password to logging as a root user into the new account? Is there a way to set one? I currently need to click on "I forgot my password" if I want to logging as a root user with my email.main.tfresource "aws_organizations_account" "this" {
name = "user1"
email = "[email protected]"
parent_id = module.organizations.sandbox_organizational_unit_id
}After that I am going into the AWS logging page, log as a root user with[email protected]and click on"I forgot my password"since I don't know the inital password

As mentioned inAWS SDK v3 docs Docs- Only HTTP API and CLI will get the base64 data. Other mediums will getUint8Arrayas response.So, we need some extra data conversion to achieve encryption and decryption using SDK.const { KMSClient, EncryptCommand, DecryptCommand } = require('@aws-sdk/client-kms');
const client = new KMSClient({ region: AWS_REGION });
// Encrypt
// Convert Uint8Array data to base64
const input = {
KeyId: kmsKey,
Plaintext: Buffer.from(JSON.stringify(credentials)),
};
const command = new EncryptCommand(input);
const encryptedBlob = await client.send(command);
const buff = Buffer.from(encryptedBlob.CiphertextBlob);
const encryptedBase64data = buff.toString('base64');
// Decrypt
// Convert Base64 data to Uint8Array
// Uint8Array(response) convert to string.
const command = new DecryptCommand({
CiphertextBlob: Uint8Array.from(atob(item.credentials), (v) => v.charCodeAt(0)),
});
const decryptedBinaryData = await client.send(command);
const decryptedData = String.fromCharCode.apply(null, new Uint16Array(decryptedBinaryData.Plaintext));

I am using@aws-sdk/client-kmsto encrypt the data. I was getting the base64 string as a response. Now I am gettingUint8Array.const encryptedBlob = await kms.encrypt({
KeyId: kmsKey,
Plaintext: Buffer.from(JSON.stringify('data to encrypt')),
});The encrypted plaintext. When you use the HTTP API or the AWS CLI, the value is Base64-encoded. Otherwise, it is not Base64-encoded.Mentioned in AWS docsIs there any way to get base64 as response in nodeJs.

As you can to see, your SO readsnvme1n1as name of device (not/dev/sdd).So, you could apply anuser_datawith the cloud-init instructions for your EC2 instance:resource "aws_instance" "your-instance" {
..
user_data = file("user_data/ebs-mount.sh")
..
}whereuser_data/ebs-mount.shhas the next content (considering that EBS disk have xfs format):#cloud-config
hostname: your-instance
runcmd:
- sudo mkdir /custom -p
- sudo echo '/dev/nvme1n1 /custom xfs defaults 0 0' >> /etc/fstab
- sudo mount -a
output : { all : '| tee -a /var/log/cloud-init-output.log' }

Could anyone advise on how I can auto-mount an EBS volume created using Terraform and make it available on/custom?resource "aws_instance" "ec201" {
...
ebs_block_device {
device_name = "/dev/sdd"
volume_type = "gp2"
volume_size = 10
delete_on_termination = true
encrypted = true
}
...Is it possible to auto-mount it?I've read these pages:https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-using-volumes.htmlAutomatically mount an EBS volume upon starting an Amazon EC2 Linux instanceWhen I do a:> lsblk

...
nvme1n1 259:0 0 10G 0 disk
nvme0n1 259:1 0 250G 0 disk
└─nvme0n1p1 259:2 0 250G 0 part /I have a 10GB partition that is not mounted. Would it be possible to auto-mount it using terraform?

"create ec2 instance from snapshot"Your almost there. The option is called "Create image". So:Go to your snapshot.Right click and choose "Create image" (assume the volume is bootable and it works).Fill out the info required.Image (aka AMI) will be created based on your snapshot and the info you will provide.Launch an instance from the AMI.More details inCreate a Linux AMI from a snapshot.

Is it not possible to create an EC2 instance from a snapshot in AWS?I tried to create volume, but then i was stuck starting an EC2 instance with that volume. Should that not be an easy process? I don't even know, if this way is correct. I am just guessing.What steps are necessary to create a EC2 instance only from the snapshot?
