There is a simple fix. Just edit filewp-config.phpand write this code inside it.First try this:define('FS_METHOD', 'direct');Note: Do not add this to the end of the file, but just below the database information on the top of the file.define('FTP_USER', 'username'); // Your FTP username
define('FTP_PASS', 'password'); // Your FTP password
define('FTP_HOST', 'ftp.example.org:21'); // Your FTP URL:Your FTP portAlso please readthis blog post.

If you setup a key pair for your instance on creation, then there is no password for the userubuntunor is password based login enabled. You must login using your key pair.To execute commands that require elevated permissions, usesudoin front of your command. The actual command to restart apache2 depends on which Linux distribution and version you are using.sudo systemctl restart apache2orsudo service apache2 restart

You can disable and enable Lambda triggers by using following approaches withUpdate Event Source Mapping, based on how you are going to do it.Using AWS CLI: You can use AWS CLIupdate-event-source-mappingcommand with--enabled | --no-enabledparameters.Using AWS SDK (E.g NodeJS): You can use AWS SDKupdateEventSourceMappingmethod withEnabled: true || falseattribute.Using AWS REST API: You can use AWS REST APIUpdateEventSourceMappingwith"Enabled": booleanattributes.Note: You need to grant relevant permission for each of the approach to execute using IAM Roles/Users or temporarily access credentials.

Is there a way for us to disable & enable the Lambda trigger programmatically (e.g. for scheduled maintains purposes)?

I was running into a symlinks issue deploying a node Elastic Beanstalk app. Looks like symlinks is now supported for artifacts.Check out the docsartifacts:
enable-symlinks: yesAdding this to thebuildspec.ymlfile solved my issue

I have some symlinks in my github repo.When I have a Codebuild project that clones directly from github, symlinks are preserved.I switched so that Codepipeline listens for changes in mydevbranch in github, and passes the artifacts to codebuild.Since making this switch, Codebuild can't see the symlinks anymore.Is this by design, or am I perhaps missing something in how my codepipeline is configured?

Most likely you want to get the attributeDNSNamefor the LoadBalancer whose reference isRestELB. So you will need something withFn::GetAttlike (untested)"ApiRecordSet" : {
"Type" : "AWS::Route53::RecordSet",
"Properties" : {
"AliasTarget" :{
"DNSName" : { "Fn::GetAtt" : [ "RestELB", "DNSName" ]},
"EvaluateTargetHealth" : "Boolean",
"HostedZoneId" : "String"
},
"HostedZoneName" : "example.net.",
"Comment" : "A records for my frontends.",
"Name" : "api.example.net.",
"Type" : "A"
}
}
|
What I trying to connect is Loadbalancer DNS name to to Route53.
Lets look on example.
Here is Loadbabancer from template in Resource:"RestELB" : {
"Type" : "AWS::ElasticLoadBalancing::LoadBalancer",
"DependsOn": "AttachGateway",
"Properties": {
"LoadBalancerName": {"Fn::Join": ["",["Rest-ELB-", {"Ref": "VPC"}]]},
"CrossZone" : "true",
"Subnets": [{ "Ref": "PublicSubnet1" },{ "Ref": "PublicSubnet2" }],
"Listeners" : [
{"LoadBalancerPort" : "80", "InstancePort" : "80","Protocol" : "HTTP"},
{"LoadBalancerPort" : "6060", "InstancePort" : "6060","Protocol" : "HTTP"}
],
}
},And Here is Route53:"ApiRecordSet" : {
"Type" : "AWS::Route53::RecordSet",
"Properties" : {
"AliasTarget" :{
"DNSName" : [
{"Fn::Join": ["", [{"ElasticLoadBalancer": "DNSName"},"."]]}
],
"EvaluateTargetHealth" : "Boolean",
"HostedZoneId" : "String"
},
"HostedZoneName" : "example.net.",
"Comment" : "A records for my frontends.",
"Name" : "api.example.net.",
"Type" : "A",
"TTL" : "900",
}
}Just to put {"ElasticLoadBalancer": "DNSName"} didn't work. Can someone to suggest or give me correct way to add this?Thanks!

There is an account setting to enable IAM user access in addition to the permissions on individual accounts. On thebilling home page,
scroll down and look forIAM User Access to Billing Information. It might look like this:You need to edit and update this to allow IAM user access:

I have an IAM user with Administrator permissions.{
"Version": "2012-10-17",
"Statement": [

}but when I try to access "/billing" page AWS saysYou are not authorized to perform this operation.
You are currently signed in as an IAM user that does not have permissions to the requested page.I also tried to generate a specific policies like{
"Version": "2012-10-17",
"Statement": [

"Effect": "Allow",
"Action": [
"aws-portal:ViewBilling"
],
"Resource": [
"*"
]
}
]
}But it doesn't change anything. I still can't access the billing info.When I go to policy simulation page it says that permission is allowed for the user.I've seen the AWS guide and tried to follow it.http://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/billing-permissions-ref.htmlIs there something I'm missing? What could it be?

I think, all the Aws functions can return a Promise out of the box, then you can just put the call intotry/catch:let triesCounter = 0;
while(triesCounter < 2){
console.log(`try #${triesCounter}`)
try {
await kinesis.putRecord(params).promise();
break; // 'return' would work here as well
} catch (err) {
console.log(err);
}
triesCounter ++;
}

I want my function to execute X(=3) times until success.In my situation I'm runningkinesis.putRecord(from AWS API), and if it fails - I want to run it again until it succeeds, but not more than 3 tries.I'm new to NodeJS, and the code I wrote smells bad.const putRecordsPromise = function(params){
return new Promise((resolve, reject) => {
kinesis.putRecord(params, function (err, data) {
resolve(err)
});
})
}
async function waterfall(params){
try{
let triesCounter = 0;
while(triesCounter < 2){
console.log(`try #${triesCounter}`)
let recordsAnswer = await putRecordsPromise(params)
if(!recordsAnswer){
console.log("success")
break;
}
triesCounter += 1;
}
// continue ...
} catch(err){
console.error(err)
}
}
waterfall(params)I promise the err result. Afterwards, If the err is empty, then all good. otherwise, continue running the same command.I'm sure there is a smarter way to do this. Any help would be appreciated.

Is it correct to not run manual VACUUM with auto_vacuum enabled ?You generally do not need manual vacuum of any kind. If autovacuum is not keeping up, make it run more often and faster. See the autovacuum documentation.How can I monitor the progress and performance of auto_vacuum ?Watch for growth of table bloat. There is, unfortunately, nopg_stat_autovacuumor similar. You can see autovacuum working inpg_stat_activitybut only instant-to-instant. Detailed analysis requires trawling through log files with autovacuum logging enabled.How do I know it is not stuck in the same place as the manual VACUUM ?Checkpg_stat_activity. You don't know it's in the same place, and you can't even really tell if it's progressing or not, but you can see if it's running or not.Lots of improvement could be made to admin/monitoring of vacuum, as you can see. We lack people who have the time, willingness and knowledge required to do it, though. Everyone wants to add new shiny features instead.Do I still need run ANALYZE on a regular basis ?No.Is there a way to enable automatic ANALYZE, similar to auto_vacuum ?Autovacuum runs analyze (or rather VACUUM ANALYZE) when required.

We run PostgreSQL 9.3 on the AWS RDS platform. Every night at 1am we've been running a globalVACUUM ANALYZEjob.Yesterday we observed severe degradation in performance and as it turned out we had 5VACUUM ANALYZEprocesses stuck for the past 5 days. Over the same period of time the disk utilization went up by 45 gigabytes.I killed it withpg_terminate_backendbut that didn't have much impact. The processes looked dead but performance was still severely degraded. Since we are using AWS RDS, we've performed a reboot with failover and performance drastically improved right away.This morning I checked and found thatVACUUM ANALYZEwas stuck again for 5 hours. I killed it, but I suspect it is still there somewhere.Upon further investigation I confirmed thatauto_vacuumis correctly enabled, which means we do not need to run manualVACUUMbut we may need to runANALYZEon some or all of the tables.In my research I found this article:http://rhaas.blogspot.com/2011/03/troubleshooting-stuck-vacuums.htmlandhttp://wiki.postgresql.org/wiki/Introduction_to_VACUUM,_ANALYZE,_EXPLAIN,_and_COUNT.In the end, I have the following questions:Is it correct to not run manual VACUUM with auto_vacuum enabled ?How can I monitor the progress and performance of auto_vacuum ? How do I know it is not stuck in the same place as the manual VACUUM ?Do I still need run ANALYZE on a regular basis ?Is there a way to enable automatic ANALYZE, similar to auto_vacuum ?

Of course there will be latency when communicating between separate machines. If they are both in the same availability zone it will be extremely low, typically what you'd expect for two servers on the same LAN.If they are in different availability zones in the same region, expect a latency on the order of 2-3ms (per information provided at the 2012 AWS re:Invent conference). That's still quite low.Using a VPC will not affect latency. That does not give you different physical connections between instances, just virtual isolation.Finally, consider using Amazon's RDB (Relational Database Service) instead of a dedicated EC2 instance for your MySql database. The cost is about the same, and Amazon takes care of the housekeeping.

I am planning to run a web-application and expecting a traffic of around 100 to 200 users.Currently I have set up single Small instance on Amazon. This instance consist of everything – the Webserver(Apache) , the Database Server(MySQL) and the IMAP server( Dovcot). I am thinking of moving out my database server out of this instance and create a separate instance for it. Now my question is –Do I get latency while communication between my webserver and Database server( Both hosted on separate instances on Amazon )If yes, what is the standard way to overcome this ? ( or Do I need to set up a Virtual Private Cloud ?)

SQS queues do not belong to a specific VPC. There is no networking involved when creating/configuring a queue.Access to SQS queues is entirely managed with IAM permissions.With ECS, you will have to configure your task execution role properly. As an example, a policy like the following allows to send, receive and delete messages from a specific queue:{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"sqs:DeleteMessage",
"sqs:ReceiveMessage",
"sqs:SendMessage"
],
"Resource": "arn:aws:sqs:<region>:<account>:<queue name>"
}
]
}See alsoAuthentication and Access Control for Amazon SQS.

I have a ECS cluster inside the VPC. ECS have to read from a SQS. So, do I need to create SQS in the same VPC for that to communicate? Also, if say, I wanted to communicate outside VPC, how can I do that?

This is more of a philosophical question:For a simple video application, which AWS services is the the best to choose, S3 or Elemental MediaStore?andAnd at which point will one be better to an other.The question is mostly in regards to performance, as I am aware different possibilities in the sdk's.BackgroundI am making a video website for my company, which will be used for simple instructional videos (screen recordings of how to do stuff in different applications). The videos er mp4 videos made vide iMovie and are around 30s to 1min.In my website, I see no performance differences for the videos. Would I see a difference if the videos was 4k 1 hour long?I like using MediaStore simply because it seems more appropriate for videos, but is there any difference?

It happens often when your Bot Build version differs from the current Bot version. It should work if you refresh the page and choose the "Latest" from the versions tag.

So I have recently gotten on board with AWS Lambda and I've been working on a bot since yesterday afternoon but now all of a sudden, this is happening. I whenever I go to build the bot or save the intent, I just keep getting the message 'The checksum value doesn't match for the resource named 'isRecyclableGarden'.'isRecyclableGarden is one of the intents I am using within my code. I can't share the code as it's work code and I am fairly new to this. Any help on how I can work out how to validate the check sum again would be helpful as I cant actually edit or progress with this code!Pictured is the problem I am having.

You can see this error if the EC2 instance does not have the correct IAM role. Create an IAM role with the policy "AmazonEC2RoleforAWSCodeDeploy". You can't add an IAM role to an existing instance, so you'll have to launch a fresh one.Also make sure you've installed the CodeDeploy agent for the correct region, e.g. forus-east-1:apt-get -y install awscli ruby2.0
aws s3 cp s3://aws-codedeploy-us-east-1/latest/install . --region us-east-1

Now I have ec2 instance with elastic ip and I am running a site from there.
I can access that site by IP/SITE_NAME from local browsers of current machines also. SO it runs on ec2 as well as on current machine.
Now I want to link that site to my su bdomain.
So how can I do that?

I'm running a Rails 4.2 app on Elastic Beanstalk, and need to set log permissions and create the /tmp/uploads folder (plus permissions) after deploy.I was running two ebextensions scripts to do this, but on some occasions they would fail because the folder /var/app/current/ didn't yet exist.I'm presuming this is because the permissions and/or folders should be created on /app/ondeck/ first so that EB can copy the contents over to /var/app/current/, but I'm interested to see if there's a recommended and more foolproof approach to doing this?For reference, my two ebextension scripts were:commands:
01_set_log_permissions:
command: "chmod 755 /var/app/current/log/*"andcommands:
01_create_uploads_folder:
command: "mkdir -p /var/app/current/tmp/uploads/"
02_set_folder_permission:
command: "chmod 755 /var/app/current/tmp/uploads/"Thanks,
Dan

Elastic Beanstalk: what's the best way to create folders & set permissions after deploy?

The question is at very high level but however will attempt to answer that.AWS is all about providing computing infra structure in on demand basis. EC2 and RDS are the 2 different service offerings from AWS.EC2 : Elastic Compute Cloud - On demand Servers either Linux / Windows.You are provided with a Instance to which you can RD / SSHYou are free to install web server / mail server / db server / app serverThe instance health is AWS's responsibility and everything inside the instance your responsibilityRDS : Relational Database ServiceYou are provided with a deployed DB server and you can create the db instanceYou can't do a RD / telnet to connect to the RDS's physical server but you can connect to the RDS instance via clients like SSMS, MySQL workbench etc. or via JDBC / ODBC DB APIsYou can connect to the RDS instance from any internet enabled client system / application ( provided appropriate firewall rules have been enabled )By extension to the previous point, you can connect to the RDS from your app running in EC2.PS:You can install a database server in EC2 and use it / configure as you wish; but remember doing that you will hold the responsibility of the DB's uptime and health as it becomes an app running in the EC2.In the RDS, AWS will take care ( manage ) the DB instance health and you just need to concentrate on your data, schema, tables etc.
|
It seems i do not fully understand the difference between EC2 and RDS.
Are both of them separate, or is EC2 like a container for RDS.
And also if I want to access RDS, will it go through EC2??

You need to useSecret. You can use any of the staticfrommethods to get the secret. From there you can use thesecretValueFromJsonmethod to get the value.Example (secret for Postgres db):import * as secretsmanager from '@aws-cdk/aws-secretsmanager';
const dbSecret = secretsmanager.Secret.fromSecretNameV2(this, 'db-secret', 'db-secret-name');
const dbUser = dbSecret.secretValueFromJson('username').toString();
const dbPass = dbSecret.secretValueFromJson('password').toString();
const dbName = dbSecret.secretValueFromJson('dbname').toString();

I am having some trouble getting a specific Secrets Manager Secret key value to pass it to my lambda through CDK.After some time I finally realized that mySecretValueis only resolved when I actually deploy this to lambda, and not while running local through SAM CLI.
By doingcdk.SecretValue.secretsManager(secretId).toString()I get something like"{\"apiKey\":\"sdfsdf-sdfsdf-sddsf\"}", but I want to rather have the apiKey directly.
Unfortunately, in my CDK code, I cannotJSON:parse(...secretsManager(..).toString())as this will only be resolved once deployed. Before, the value is simply:{{resolve:secretsmanager:apiKey:SecretString:::}}(which seems to be a Token:https://docs.aws.amazon.com/cdk/latest/guide/tokens.html)So I guess I would need some way to tell CDK how to use the rendered value, maybe by passing a callback that transforms the rendered result - is that possible?
Are there any other tools I can use in my CDK setup that allow me to receive a specific key from a secret so that I can pass it to lambda directly?I hope the problem is understandable. Thanks in advance for your help.

Convert Glue's DynamicFrame into Spark's DataFrame to add year/month/day columns and repartition. Reducing partitions to one will ensure that only one file will be written into a folder, but it may slow down job performance.Here is python code:from pyspark.sql.functions import col,year,month,dayofmonth,to_date,from_unixtime
...
df = dynamicFrameSrc.toDF()
repartitioned_with_new_columns_df = df
.withColumn(“date_col”, to_date(from_unixtime(col(“unix_time_col”))))
.withColumn(“year”, year(col(“date_col”)))
.withColumn(“month”, month(col(“date_col”)))
.withColumn(“day”, dayofmonth(col(“date_col”)))
.drop(col(“date_col”))
.repartition(1)
dyf = DynamicFrame.fromDF(repartitioned_with_new_columns_df, glueContext, "enriched")
datasink = glueContext.write_dynamic_frame.from_options(
frame = dyf,
connection_type = "s3",
connection_options = {
"path": "s3://yourbucket/data”,
"partitionKeys": [“year”, “month”, “day”]
},
format = “parquet”,
transformation_ctx = "datasink"
)Note that thefrom pyspark.qsl.functions import colcan give a reference error, this shouldn't be a problem as explainedhere.

The current set-up:S3 location with json files. All files stored in the same location (no day/month/year structure).Glue Crawler reads the data in a catalog tableGlue ETL job transforms and stores the data into parquet tables in s3Glue Crawler reads from s3 parquet tables and stores into a new table that gets queried by AthenaWhat I want to achieve is the parquet tables to be partitioned by day (1) and the parquet tables for 1 day to be in the same file (2). Currently there is a parquet table for each json file.How would I go about it?One thing to mention, there is a datetime column in the data, but it's a unix epoch timestamp. I would probably need to convert that to a 'year/month/day' format, otherwise I'm assuming it will create a partition for each file again.Thanks a lot for your help!!

The message "RESOURCE:ENI" indicates that it's a problem with allocating an elastic network interface.Per thedocs, at2.mediumshould be able to allocate 3 ENIs. So, assuming that ECS assigns a distinct ENI to each container, that would be the reason that you can't assign more than three containers to an instance.But you're indicating that you're actually limited to 2 containers per instance. Which makes me wonder if you're somehow exceeding thelimit of ENIs per region. That shouldn't happen unless ENIs are being detached and not removed (which could possibly happen if your IAM permissions aren't correct). I recommend looking at the ENI page in the AWS Console to make sure that you don't have a lot of unattached ENIs.

I have 10 service/task definitions each of which requires 512 memory and 10 cpu (from container definition).
I have three t2.medium instances each of which has 4GB memory.
So it should be no problem to launch up to 24 task instances.However those three instances run maximum only 7 services (3/2/2).
For the services that are not running in "events" tab there are following errors:service integrityCheck was unable to place a task because no container instance met all of its requirements. The closest matching container-instance 3e2dbe6a-7a07-46f2-846b-ccccb9adaeee encountered error "RESOURCE:ENI".I tried updating AMI on ec2 instances to latest ecs-optimized but it did not help. It seems that one ec2/container instance can't start more than 3 tasks? Strange thing is that it worked fine like 1 month ago (all 10 services were running) and those errors appeared ~20-26 days ago.Any idea?Each service uses awsvpc network mode and awslog log driver.Here are my network interfaces listed:

You can't stop a DB instance that is in a Multi-AZ deployment.http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_StopInstance.htmlModify the instance so that it is no longer Multi-AZ. After this modification is complete, you should be able to stop it. You can switch it back to being Multi-AZ after it is restarted.

I spun up two RDS instances in the same VPC. Both are postgresql.While the m4.xlarge one has multi-AZ enabled and is encrypted. The t2.micro has either. That is the only difference between the two instances. It is strange that t2.micro instance can be stopped but m4.xlarge can't. The "stop" option is grayed out for m4.xlarge.Why can't I stop this one? Does it have to do with the multi-AZ thing?

OK, so I got it working...First I switched from zsh to bash shell via the terminal command:exec bashThen I ran:pip --versionJust to confirm that pip and Python where both in fact installed and working.From here I ran:brew install awscliThis was the critical missing ingredient that I did not have on my first run through.At the end of the install process Amazon prints to screen a list of "Caveats" for completing installation.According to the Caveats I took the following two steps...First, added the following to ~/.bashrc to enable bash completion:complete -C aws_completer awsThen added the following to ~/.zshrc to enable zsh completion:source /usr/local/share/zsh/site-functions/_awsNow I am able to run the command "aws" via either shell.
|
I followed all the instructions provided by Amazon for installing AWS CLI found here:http://docs.aws.amazon.com/cli/latest/userguide/cli-install-macos.htmlMy machine is running the Zsh Shell. So in step three I edited .zshrc instead of .bash_profile.The error message I am receiving iszsh: command not found: awsHere is how the .zshrc file looks now.export PATH="$HOME/.bin:$PATH"
export PATH="/usr/local/bin:$PATH"
export PATH=~/.local/bin:$PATH
eval "$(hub alias -s)"
export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scriptingI believe that the export PATH=~/.local/bin:$PATH might be redundant given the line above it that was already in place.

Yes. You can useJMESPathsyntax to filter the results ofaws autoscaling describe-auto-scaling-groupscommand down to only those groups matching some tag's key/value pair. This uses the--queryparameter, which is available for filtering on most AWS CLI commands.Example to query by a single tag:The example below filters results based on a tag where Key = 'Environment' and Value = 'Dev'.aws autoscaling describe-auto-scaling-groups --query "AutoScalingGroups[? Tags[? (Key=='Environment') && Value=='Dev']]".AutoScalingGroupNameExample to query by multiple tags:The example below filters results based on tags where Key = 'Environment' and Value = 'Dev', and Key = 'Name' and Value = 'MyValue'. This uses a pipe to query for the second tag on the resulting autoscaling groups of the query for the first tag.aws autoscaling describe-auto-scaling-groups --query "AutoScalingGroups[? Tags[? (Key=='Environment') && Value=='Dev']] | [? Tags[? Key=='Name' && Value =='MyValue']]".AutoScalingGroupNameFurther ReadingAWS Documentation - aws autoscaling describe-auto-scaling-groupsAWS Documentation - Controlling Command Output from the AWS Command Line Interface

I had the same issue. Turns out that when you enable CodeCommit the CLI looks for a remote called "codecommit-origin" and if you don't have a git remote with thatspecificname it will throw that error.Posting this for anyone else who stumbles upon the same issue.

The documentation is a little confusing, but you need to construct a filter name that includes thetag:prefix and your tag name. Here's a working example:var AWS = require('aws-sdk');
var ec2 = new AWS.EC2({
region: 'eu-west-1'
});
var params = {
Filters: [
{
Name: 'tag:Project',
Values: ['foo']
}
]
};
ec2.describeInstances(params, function (err, data) {
if (err) return console.error(err.message);
console.log(data);
});This returns all instances that have the tagProjectset to the valuefoo.

I am trying to use the describeInstances function in amazon ec2 to get details about my instance
using my tag id. In the documentation it mentions use the filter,tag:key=value - The key/value combination of a tag assigned to the
resource, where tag:key is the tag's key.I tried it in the following way:var params1 = {
Filters : [
{
Tags : [ {
Key : key_name,
Value : key_value
} ]
}
]
};
ec2.describeInstances(params1, function(data, err) {
}), but I get an error: Unexpected Token at Tags :

Manuel,as mentioned, the return info is inside the Payload element in the returned json. Payload is a boto3 object type that you need to access it's contents through it's read() method.The code I used to get the python dictionary that I return from my lambda functions is this:payload = json.loads(response['Payload'].read())
statusCode = payload.get('statusCode')
message = payload.get('message')
results = payload.get('results')

Im currently writing a python script that interacts with some AWS lambda functions. In one of the functions, my response contains a list which I need in my script.Problem is that when I use theinvoke()function, the response is a json which contains request information.response = aws_lambdaClient.invoke(FunctionName = 'functionName', Payload = payload)The function that im using has this as a returnreturn {'names': aList, 'status': 'Success!'}If I print out the response, I get this:{'ResponseMetadata': {'RequestId': 'xxxxxxxxx', 'HTTPStatusCode': 200, 'HTTPHeaders': {'date': 'Thu, 07 Nov 2019 14:28:25 GMT', 'content-type': 'application/json', 'content-length': '51', 'connection': 'keep-alive', 'x-amzn-requestid': 'xxxxxxxxxx', 'x-amzn-remapped-content-length': '0', 'x-amz-executed-version': '$LATEST', 'x-amzn-trace-id': 'root=xxxxxxxxx;sampled=0'}, 'RetryAttempts': 0}, 'StatusCode': 200, 'ExecutedVersion': '$LATEST', 'Payload': <botocore.response.StreamingBody object at 0x0000023D15716048>}And id like to get{'names': aList, 'status': 'Success!'}Any idea on how can I achieve this? Or should I find another way of getting the data (Maybe putting the list i need in an s3 bucket and then getting it from there).

If you are using API Gateway HTTP APIs (not sure if this is relevant for the REST APIs):Lets say I have an endpoint at/POST products. I had to addanother endpointat/OPTIONS productsand integrate it with a simple Lambda function that just returns the HTTP 200 OK (or HTTP 204 No Content), and the"Access-Control-Allow-Origin": "*"header (or even better, specify the URL of your origin/client).This is because browsers issue a preflight/OPTIONSrequest to the same endpoint, before issuing the actual request (seemore), for all HTTP requests exceptGETandPOSTwith certain MIME types (source).

Your AWS credentials on your local machine can't be seen by theawscliprogram on your EC2 instance. If you want to run the S3 copy command on the EC2 instance, you have two options:1) Runaws configureon the EC2 instance and define the credentials on that machine (not recommended)or2) Create anIAM rolewith the required permissions to copy the files (for example, with the AmazonS3ReadOnlyAccess policy) andattach the role to your EC2 instance

Network Access Control Lists (ACLs) mimic traditional firewallsimplemented on hardware routers. Such routers are used to separate subnets and allow the creation of separate zones, such as aDMZ. They purely filter based upon the content of the packet. That is their job.Security Groupsare an added capability in AWS that provides firewall-like capabilitiesat the resource level. (To be accurate, they are attached to Elastic Network Interfaces, ENIs). They arestateful, meaning that they allow return traffic to flow.In general, the recommendation is to leave NACLs at their default settings (allow all traffic IN & OUT). They should only be changed if there is a specific need to block certain types of traffic at the subnet level.Security Groups are the ideal way to control stateful traffic going in and out of a VPC-attached resource. They are THE way to create stateful firewalls. There is no other such capability provided by a VPC. If you wanted something different, you could route traffic through an Amazon EC2 instance acting as a NAT and then you would have full control over how it behaves.
|
From what I read, stateless firewalls are used more for packet filtering. Why is AWS NACL stateless?NACLs force too big a range of ports to be opened for the ephemeral ports.Is there a way to create stateful firewalls on AWS other than Security Groups? Security Groups feel too granular and may get omitted by mistake.

You are using the CMK to encrypt/decrypt your data which is not what you should be using it for. The CMK is limited to encrypting up to 4k data because it is meant to create and encrypt/decrypt the data key. Once you’ve created this data key you then use it to encrypt your data without the use of AWS KMS. You could use OpenSSL with the data key and this process is not dependent on KMS. Keep in mind that you have to handle the data key very carefully and best practice is once you've used it to encrypt data, you must encrypt that data key using KMS then store that encrypted key (as metadata) along with the encrypted data. The process of decrypting the data will start with you using KMS to decrypt the data key then using OpenSSL for example to use the decrypted data key as the key to decrypt your data(XML Payload).
|
I am trying to encrypt a large XML payload using AWS KMS Encryption SDK. I came across thislinkwhich states that there is a limit on bytes of data that can be encryptedYou can encrypt up to 4 kilobytes (4096 bytes) of arbitrary data such
as an RSA key, a database password, or other sensitive information.Does KMS not support encryption of data that is more than 4 KB? Is there a workaround to handle data of size more than 4 KB?

The body of viewer requests and origin responses is not available to Lambda@Edge functions -- only the headers.While it isn't entirely clear what you are trying to do once you get access to the data in the body, if that's something you need, then here's the AWS workaround:Look into API Gateway, which does have access to the request body. You can deploy an API Gateway Regional Endpoint and add that endpoint as a second origin to your CloudFront distribution. You can then use Lambda@Edge in an Origin Request trigger to divert those requests to the alternate origin (your new "API," which can generate the response you want, based on thePOSTrequest you receive).

I have a static website hosted on AWS Cloudfront.
On a route I need to accept the POST method because is the redirect of the OAuth server so I decided to develop a [email protected] idea is to register the lambda on the 'Viewer Request' and intercept the POST method, reading the body and copy the values on the headers in order to make them readable from my static website (I know I can access the Referrer header with javascript).I set up the Lambda and I can intercept the POST letting all the other methods pass through.The problem is that I cannot find a way to read the body of the POST request, I googled it with no result.Any advice on I can do it? Is there any parameter I have to configure on Cloudfront side?

If you wish to use aspecific VPC and subnet, just insert their values:{
"Resources": {
"MyServer": {
"Type": "AWS::EC2::Instance",
"Properties": {
"InstanceType": "t2.micro",
"SubnetId": "subnet-abc123",
"ImageId": "ami-abcd1234"
}
}
}A subnet always belongs to a VPC, so specifying the subnet will automatically select the matching VPC.

So your load balancer is doing the SSL termination and always communicating with your server via HTTP. This means you have to check the 'x-forwarded-proto' header to determine if the original request is over HTTPS.There are several other ways to configure SSL on AWS, including termination on the web server, but SSL termination on the ELB is the generally preferred method on AWS. You just have to be aware that in this configuration the request between the ELB and the web server isn't actually over SSL so you have to check the header accordingly.

Im trying to redirect HTTP requests to my site to HTTPS. Its been extraordinarily hard. My code is:var express = require('express');
var app = express();
app.use(function(req, res, next) {
console.log('req.protocol is ', req.protocol);
console.log('req.secure is ', req.secure);
if (req.url !== '/health' && !req.secure) {
console.log('redirecting .........');
return res.redirect('https://www.example.net/catch');
}
next();
});
app.get('/catch', function(req, res) {
res.send('Hello World!');
});
app.get('/', function(req, res) {
res.send('Hello World!');
});
app.get('/health', function(req, res) {
res.send('Hello World!');
});
app.listen(8080, function() {
console.log('Example app listening on port 8080!');
});The load Balancer health check goes to '/health'. Every other request that isnt a health check, and is HTTP (rather than HTTPS) should be caught and redirected to https. However, I end up in an infinite loop as req.protocol always returns 'http' for http or https requests. req.secure therefore is false every time and I end up in a loop. Any ideas why this is?

AWS Transit Gatewaynow provides an option to do what you wish, although you will want to consider the costs involved -- there are hourly and data charges. There is a reference architecture published in which multiple VPCs share a NAT gateway without allowing traffic between the VPCs:https://aws.amazon.com/blogs/networking-and-content-delivery/creating-a-single-internet-exit-point-from-multiple-vpcs-using-aws-transit-gateway/
|
I have one VPC where i configuredNAT Gateway. Another VPC(s) do not have any "public subnet" nor IGW. I would like to share single NAT Gateway among many VPCs.
I tried to configure Routing table but it does not allow to specify NAT Gateway from different VPC.
As posible solution, I installed http/s proxy in VPC with IGW and configured proxy settings on every instance in different VPC. It worked, but I would like useNAT Gatewaydue to easier management.
Is it possible to make this kind of configuration at AWS?
There are few VPCs and I do not want to add NAT Gateway to each VPC.Zdenko

I have hosted a server app on AWS and RDS for relational DB. Though I opted for free account, RDS is being charged at $0.0025 per hour amounting to $18 a month.I read some documentation but still not able to figure this out. Is this the way it is or is there a way to get free RDS account for testing purpose?Thanks

The blog post you linked is still basically valid, here's what exactly you need to do:First put SDK into subfolder inside libraries folder (for ex. aws-sdk-for-php). This is the file awslib.php in libraries folder:class Awslib {
function Awslib()
{
require_once('aws-sdk-for-php/sdk.class.php');
}
}And then just use whatever AWS service you wish in the controller, let's say it's SQS:$this->load->library('awslib');
$sqs = new AmazonSQS();
$response = $sqs->list_queues();
var_dump($response->isOK());Don't forget to set your credentials and rename the sample config file.

Is there already a handy CI 2 library for AWS SDK 1.5.x? If not, what would be the steps to make it into one?I found a 3 year old posting about integrating Tarzan (the pre-pre-cursor to AWS SDK) to CI 1 here:http://blog.myonepage.com/integrating-tarzan-amazon-web-services-php-to. I am wondering if these instructions still hold? One difference I noticed was that the way AWS SDK 1.5.3 declares its Access Identifiers has changed and I am not quite sure how to proceed to inform CI about this.Thanks!

Here is another solution. Since folders technically do not exist in S3 and merely a UI feature, "folders" in S3 are ultimately called prefixes.You can trigger an EventBridge Notification on an S3 folder with the following event pattern:{
"source": ["aws.s3"],
"detail-type": ["Object Created"],
"detail": {
"bucket": {
"name": ["<bucket-name>"]
},
"object": {
"key": [{
"prefix": "<prefix/folder-name>"
}]
}
}
}

Trust policies define which principal entities (accounts, users, roles, and federated users) can assume the role. Every IAM role requires a trust policy.You have to specify a trust policy when creating a role through the CLI. Identity-based policies (managed/inline) can be attached to a role afterwards by usingattach-role-policyorput-role-policycommands.The following trust policy lets Lambda service assume this role. You have to provide this file as input to the command usingassume-role-policy-documentoption.trust-policy.json{

tmpfs 15G 0 15G 0% /dev/shmI surprised not only by how little was available/how much space was used,(I am on the/dev/xvda1instance) but also surprised to see 2 alternative filesystems.To investigate what was taking so much space, I randu -hin~and saw the list of all directories on the server. Their reported size in aggregate should not be even close to 7 gb...which is why I ask "what is taking up all that space??"The biggest directory by far was the~directory containing 165MB all other were 30MB and below. My mental math added it up to WAY less than 7gb. (if I understand du -h correctly, all directories within ~ ought to be included within 165MB...so I am very confused how 7 gb could be full)Anyone know what's going on here, or how I can clean up the space?

If you just confirm the suggested value by hitting enter, it will remain unchanged.orChange just theaws_secret_access_keyby typing$ aws configure set aws_secret_access_key <secret_key>orYou can edit the AWS credentials directly by editing the AWS credentials file on your hard drive. Theaws_access_key_idand theaws_secret_access_keyare stored in the~/.aws/credentialsfile by default. You can use any editor to edit them, such as vim, emacs, or nano, e.g.$ nano ~/.aws/credentialsAdditionally, you can have credentials for many different AWS accounts in the same credentials file by using profiles. As a result, if you have onedevelopmentaccount and oneproductionaccount, the content of the file may look like[development]
aws_access_key_id = <key id of dev account>
aws_secret_access_key = <secret access key of dev account>
[production]
aws_access_key_id = <key id of prod account>
aws_secret_access_key = <secret access key of prod account>(naturally, you need to replace<key id of dev account>,<secret access key of dev account>, etc with the actual IAM credentials for each account respectively)Ref:AWS CLI Configuration Variable

I'm trying to run a Lambda function from a console application. The idea is for it to run a quick fire & forget lambda function without waiting for lambda function to return. My code doesn't appear to be executing the lambda function at all though. I know the function works because I can run with the test. When I run the below code I just get a task cancelled exception.var jsonSerializer = new JsonSerializer();
var lambdaConfig = new AmazonLambdaConfig() { RegionEndpoint = RegionEndpoint.USEast2 };
var lambdaClient = new AmazonLambdaClient(lambdaConfig);
using (var memoryStream = new MemoryStream())
{
jsonSerializer.Serialize(myData, memoryStream);
var lambdaRequest = new InvokeRequest
{
FunctionName = "MyFunction",
InvocationType = "Event",
PayloadStream = memoryStream
};
var result = Task.Run(async () => { return await lambdaClient.InvokeAsync(lambdaRequest); }).Result;Does anyone have some insight into what I'm doing wrong?Thanks!

What can I do by creating custom CloudWatch metrics?
I couldn't get the idea behind creating custom metrics in CloudWatch after I read the docs.I’ve created a new metric:mon-put-data --metric-name MyMetric --namespace "MyService" --value 2 --timestamp 2011-03-14T12:00:00.000ZWhat can I get from this metric?
I couldn't understand the custom metrics.

Elastic load balancing and Elastic IP are both region specific, I would assume that auto scaling is region specific and only between the availability zones in that region. The white paper on building fault tolerant applications doesn't explicitly state that you could auto-scale across regions butit does say that you can across zones."Auto Scaling can work across multiple Availability Zones in an AWS Region, making it easier to automate increasing and
decreasing of capacity."I would believe if they supported multi-region, they would explicitly say so.Thinking about this further, I'm not so sure it's even a good idea to auto-scale across regions. Auto-scale is more geared for a specific tier of your application.For example, if a region was to go down, you would not want some of your web servers to use services across a slow link to another region (potentially) across the country.Instead you would want route 53 to route the traffic to an autonomous stack running it's own auto-scaled layers in a separate region.see this hosting charteverything from ELB down is region specific.ShareFolloweditedOct 17, 2012 at 0:52answeredOct 16, 2012 at 3:25John MoralesJohn Morales31644 silver badges77 bronze badges11Dear John, you were perfect until the paragraph before the last, you thought Route 53 but said S3 (simple storage service).–Alessandro OliveiraOct 16, 2012 at 10:42Add a comment|

I hope you can provide a quick response to my question.Is it possible to create auto scaling group which spans across regions ? Consider this scenario - Lets say all the availability zones in west are unavailabe. Can we configure auto scaling so that if the instance in US.West are down, create an instance in east zone ?I dont think it is possible, because we need to specify the region for AWS_AUTO_SCALING_URL while using Command line scripts, which restricts the creation of launch configs, auto scaling group within that region only.So we can only hope all the AZ's in that region are not down or move to VPC is that right ?

I wrote a script that might help with what you need, detailshere, sourcehere.But first of all, and really, this is the most important thing, you need to consider what defines a 'user'. Whilst it might seem obvious in descriptive terms, in technical terms you need to start to talk about requests per second.Now that bug bear is out of the way, to run load tests against Amazon using ELBs there's a couple of things you might want to know about.At this sort of load you'll very likely need to ask Amazon to 'pre-warm' things. Last time I looked into this I found that an ELB is essentially a software load balancer running on a simple instance. Like all things, these instances have a throughput limit and tend to max out at around (very vague) 40 requests a second. They will autoscale but the algorithm for this is not suited to load testing so pre warming is Amazon spinning up X ELBs beforehand where X is based on the information you provide to them in your request (see my first point around requests per second, not users).ELBs can cache DNS which in load testing can cause issues. If your test tool is java based (like JMeter) use: -Dsun.net.inetaddr.ttl=0Whatever solution you opt for, be very aware that your test itself can become the bottleneck, you should check for this first before blaming the application you're testing.ShareFollowansweredAug 1, 2012 at 21:16Oliver LloydOliver Lloyd4,95477 gold badges3636 silver badges5555 bronze badgesAdd a comment|

I have a PHP application which I have running on Amazon's Web Services. It's a relatively simple PHP script which basically does a simple write to an SQL database. This Database is an Xtra Large RDS instance. The PHP is running on a large EC2 instance behind a load balancer.What I would like to do is to stress test my script to simulate about 800 users all connected at the same time (yes, that truely is the estimate).I have heard about Siege, but I wasn't sure how to go about using it to test my application. If I try running it from my connection at home, I'm not sure that my PC / ADSL is even fast enough to create enough traffic to simulate 800 users attacking the EC2s (thus the RDS) all at once.Is it advisable to start another EC2 instance in another zone to simply "Siege" my application? Or perhaps running 2 EC2 instances, both sieging with 400 users each!?One hope that this would test the load balancing, the RDS and the EC2s thoroughly.Does anyone have experience with this kind of high-concurrent-user testing?Andy

I figured it out.Apparently, you cannot access elasticache clusters from outside AWS by default. In order to do this, you need to create a VPN through AWS and connect to that in order to reach your desired cluster.The steps to do this are outlined in this AWS tutorialhere, but in more simple terms all I did was the following:Create and import a certificate of authority using the AWS Certificate Manager. You will use this certificate to authorize your VPN connection.Create a VPN Client Endpoint and attach the key and certificate generated in the previous step with it.Associate the VPC being used on your elasticache cluster with the VPN endpoint.Authorize all traffic on your VPN for all users.Add a route to the route table of your VPN endpoint to allow access from anywhere (0.0.0.0/0).Download VPN client configuration file locally and connect to the VPN using "openvpn" (you may need to brew install this) with your certificate and key created in the first step.This worked for me and I'm glad I figured it out. Now I can connect to my Redis cluster from my local machine using "redis-cli"!ShareFollowansweredOct 16, 2021 at 6:43Aaron MednickAaron Mednick58033 gold badges88 silver badges1818 bronze badgesAdd a comment|

I recently created a Redis cluster on AWS elasticache and am having trouble connecting via redis-cli from my local machine. Every time I run the command:redis-cli -h <redis_cluster_domain> -p 6379the connection is never established and eventually exits due to timeout.Eventually, I figured it's blocking due to a setting on the security group, so I edited the inbound rules to allow all traffic from my IP address. Even after doing this I still cannot connect to the cluster. Any ideas why this might be?

],
'Instances': [

...Notice that the response is:A dictionaryWhereReservationsis alistcontaining:Instances, which is alistTherefore, the code really needs to loop through all Reservations and instances.At the moment, your code is looping through the Reservations (incorrectly calling them instances), and is then only retrieving the first ([0]) instance from that Reservation.You'll probably want some code like this:for reservation in response['Reservations']:
for instance in reservation['Instances']:

Elastic Load Balancer is a distributed system. It does not have a single public IP address. Instead, when you create an ELB, you are given a DNS name such as ExampleDomainELB-67854125.us-east-1.elb.amazonaws.com.
Amazon gives a facility to set up a DNS CNAME entry pointing for e.g. www.exampledomain.com to the ELB-supplied DNS name.Also, ELB is directing to one of your instances. Hence, creating a static IP address for ELB will not be feasible.So as a solution if you need to set your 'A' record from your domain pointing to your ELB in Route53 :Select 'Yes' for Alias.Set Alias target as your Load Balancer DNS.Second way is similar by selecting the CNAME in Route53 and pointing the Alias Target to your ELB.This should help.ShareFollowansweredApr 4, 2019 at 16:32Aress SupportAress Support1,38566 silver badges1313 bronze badgesAdd a comment|

As was commented on yourrelated question, you really need to involve your network personnel to identify the correct solution.With--no-verify-ssl, the traffic should still beencryptedbut itis notsecure.With this option, you are explicitly disabling the mechanism designed to prevent misuse or forgery of an SSL certificate, and doing so makes it impossible for aws-cli to determine with reasonable confidence that the peer system with which it is communicating is indeed Amazon S3, not an impostor server, and not a man-in-the-middle observer/attack/exploit.A need (or perceived need) to disable this validation is a sign of a defect in the system that needs to be resolved, such as by adding your enterprise CA to your local system trust store (assuming that's the issue -- it's the only marginally legitimate explanation that comes to mind, and if that is the actual problem, then I would argue that your organization is manipulating TLS in an improper way).This workaround should be avoided.ShareFollowansweredFeb 14, 2019 at 15:58Michael - sqlbotMichael - sqlbot174k2727 gold badges367367 silver badges440440 bronze badgesAdd a comment|

I also found this to be counter-intuitive and confusing at first. However, thisisactually the expected (and documented) behavior.When you attach a Cognito event to a function as a trigger,Serverlesswill create a user pool for you, without even being asked.Source:This will create a Cognito User Pool with the specified name.So in your case, one user pool is being created by thecognitoUserPoolevent, and the other is being created by yourResourcessection. The one created byResourcesis correct (has the custom password policy), and the one created by the lambda trigger has default configuration. The fix is described under the"Overriding a generated User Pool"heading.You prefix the User Pool key in the Resources section withCognitoUserPool, which will cause both your trigger and your resource to refer to the same User Pool in the generated CloudFormation template.In your case, this means simply changing this:resources:
Resources:
MyUserPool:
Type: "AWS::Cognito::UserPool"to this:resources:

An Amazon CloudWatch custom metric is only created when data is stored against the custom metric.

I had already created 7 other metrics based on some log files I send to CloudWatch with no problems.Some time ago we had a problem with MongoDB connection, and I identified that through logs, so I'd like to create a Metric, so that I can create an Alarm based on it. I did create the Metric, but (of course) there are no data being fed into that Metic, because no more "MongoError" messages exists.But does that also mean that I can't even access the Metric to create the Alarm? Because this is what is happening right now. The Metric cannot be seen anywhere, only in the "Filters" section of the Logs, which won't allow me to create Alarms or create graphics or anything.I have already posted this on AWS forums but that usually doesn't help.

IfTimestampis the partition key and not the sort key. Then, you have two problems:In aQueryoperation, you cannot perform a comparison test (<, >, BETWEEN, ...) on the partition key. The condition must perform an equality test (=) on a single partition key value and,optionally, one of several comparison tests on a single sort key value. For example:KeyConditionExpression: 'HashKey = :hkey and RangeKey > :rkey'You have a syntax error in yourKeyConditionExpression,obviously. Keep in mind thatTimestampis areserved wordin DynamoDB. So, you'll have to useExpressionAttributeNamesfor that:(Assuming you have anIdpartition key andTimestampsort key)var params = {
TableName: "Table2",
KeyConditionExpression: "Id = :id AND #DocTimestamp BETWEEN :start AND :end",

I've got a map variable that identifies existing s3 buckets:resource "aws_s3_bucket" "bucket" {
for_each = var.s3_replication
bucket = each.value.source
#other configuration
}
variable "s3_replication" {
description = "Map of buckets to replicate"
type = map
default = {
logs = {
source = "logs_bucket",
destination = "central_logs_bucket"
},
security = {
source = "cloudtrail_bucket",
destination = "central_security_bucket"
}
}
}Since these buckets already exist, I am trying to import them and then apply the a configuration to them to update the resources. Unfortunately, I am not able to figure out how to do a terraform import on these. I've tried:terraform import aws_s3_bucket.bucket["logs"] logs_bucket
terraform import aws_s3_bucket.bucket[logs] logs_bucket
terraform import aws_s3_bucket.bucket[0] logs_bucket
terraform import aws_s3_bucket.bucket[0].source logs_bucket
terraform import aws_s3_bucket.bucket[0[source]] logs_bucketAll failing with a different error. Any idea on how to import existing resources listed on a map?

Based on the comments.The issue was caused because the CloudFront distribution in question did not have Alternate Domain Name set witch matches the record in Route53. Fromdocs:The distributionmust include an alternate domain name that matches the domain namethat you want to use for your URLs instead of the domain name that CloudFront assigned to your distribution.ShareFollowansweredAug 30, 2020 at 11:12MarcinMarcin227k1414 gold badges267267 silver badges322322 bronze badgesAdd a comment|

I'm creating an A record in my Route 53 hosted zone for a subdomain. When I select "Alias to Cloudfront distribution", only US East zone shows in the list, containing an undesired distribution:However I want to point to another distribution which is not showing in the list. Any idea why it's not showing? The distribution is ready and can be accessed using the cloudfront URL, pointing to a static s3 hosting bucket. I created it using amplify cli hosting, s3+cloudfront option if it matters.Thanks for any help.

You can run it in a loop over the results oflist-buckets.For example:for bucket_name in $(aws s3api list-buckets --query "Buckets[].Name" --output text); do
echo ${bucket_name}
encryption_info=$(aws s3api get-bucket-encryption \
--bucket ${bucket_name} 2>/dev/null)
if [[ $? != 0 ]]; then
echo " - no-encryption"
else
echo " - ${encryption_info}"
fi
doneIf bucket has no encryptionget-bucket-encryptionreturns error, so I assume above that any error means that there is no encryption.ShareFollowansweredAug 28, 2020 at 23:26MarcinMarcin227k1414 gold badges267267 silver badges322322 bronze badges1thx, just what i needed!

My account has a few hundred buckets, I need to be able to show the encryption status for all of these. I'd like to be able to do this via the CLI, I see there is a command 'get-bucket-encryption' operation but I can't figure out how to run this against all buckets rather than just a specific bucket.

I am using AWS with (Basic support plan). I want to know which version of Spark and Hadoop (HDFS) is getting used in AWS glue jobs. So that I can setup the same environment in my local machine for development.Or if i get to know version of Spark then corresponding which version of Hadoop is used by AWS glue jobs or vice-versa.As I am using Basic Support plan. So, I can't raise case to support center.
Any idea where I can check in AWS glue jobs... Spark and Hadoop version?Any kind of help and suggestion is appreciated. Thanks!

Unfortunately, it seems that the library has been updated since the accepted answer was written and the solution no longer is the same. After some trial and error, this appears to be the more current method of handling the signing (usinghttps://pkg.go.dev/github.com/aws/aws-sdk-go-v2):import (
"context"
"net/http"
"time"
"github.com/aws/aws-sdk-go-v2/config"
"github.com/aws/aws-sdk-go-v2/aws/signer/v4"
)
func main() {
// Context is not being used in this example.
cfg, err := config.LoadDefaultConfig(context.TODO())
if err != nil {
// Handle error.
}
credentials, err := cfg.Credentials.Retrieve(context.TODO())
if err != nil {
// Handle error.
}
// The signer requires a payload hash. This hash is for an empty payload.
hash := "e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855"
req, _ := http.NewRequest(http.MethodGet, "api-gw-url", nil)
signer := v4.NewSigner()
err = signer.SignHTTP(context.TODO(), credentials, req, hash, "execute-api", cfg.Region, time.Now())
if err != nil {
// Handle error.
}
// Use `req`

Hello StackOverflow AWS Gophers,I'm implementinga CLI with the excellentcobra/viper packages from spf13. We have an Athena database fronted by an API Gateway endpoint, which authenticates with IAM.That is, in order to interact with its endpoints by using Postman, I have to defineAWS Signatureas Authorization method, define the corresponding AWS id/secret and then in the Headers there will beX-Amz-Security-Tokenand others. Nothing unusual, works as expected.Since I'm new to Go, I was a bit shocked to see that there are no examples to do this simple HTTP GET request with theaws-sdk-goitself... I'm trying to use the shared credentials provider (~/.aws/credentials), as demonstrated for the S3 clientGo code snippets from re:Invent 2015:req := request.New(nil)How can I accomplish this seemingly easy feat in 2019 without having to resort to self-cookednet/httpand therefore having to manually read~/.aws/credentialsor worse, go withos.Getenvand other ugly hacks?Any Go code samples interactingas clientwould be super helpful. No Golang Lambda/server examples, please, there's plenty of those out there.

A better solution was to omit "Unit" altogether, which allowed AWS to choose the appropriate unit, not only in scale but in category.ShareFollowansweredFeb 11, 2019 at 19:34StevenSteven9241010 silver badges1919 bronze badges1This worked for me in my situation as well.

Using the JS AWS SDK and passing the following parameters:{

"EndTime": 1549321515,
"MetricDataQueries": [
{
"Id": "m1",

"Value": "i-[redacted]"
}
]
},
"Period": 300,
"Stat": "Average",
"Unit": "Gigabytes"
}
}
]
}This is the output:[
{
"Id": "m1",
"Label": "NetworkOut",
"Timestamps": [],
"Values": [],
"StatusCode": "Complete",
"Messages": []
}
]The query closely matches the sample request found athttps://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_GetMetricData.html#API_GetMetricData_ExamplesI am sure that the instance is a valid instance that has definitely had NetworkOut traffic during that date range.What reason could account for the lack of elements inValuesarray?

Why is GetMetricData returning an empty set of values?

UPDATE:For AWSMobileClient ~> 2.12.0, you can fetch user attributes as follows.AWSMobileClient.default().getUserAttributes { (attributes, error) in
if(error != nil){
print("ERROR: \(error)")
}else{
if let attributesDict = attributes{
print(attributesDict["email"])
print(attributesDict["given_name"])

It looks like AWS has recently released a feature to launch an instance with encrypted volume based on non-encrypted AMI.Launch encrypted EBS backed EC2 instances from unencrypted AMIs in a single stepFrom the CloudFormation perspective, you need to overwrite AMI block device configuration. So for example, you can write like this:BlockDeviceMappings:
- DeviceName: "/dev/xvda"
Ebs:
VolumeSize: '8'
Encrypted: 'true'This will start an instance with encrypted root EBS from non-encrypted AMI with a default KMS keyShareFollowansweredMay 28, 2019 at 13:19dhavrykdhavryk12111 silver badge55 bronze badgesAdd a comment|

Working on cloud formation script which will create simple ec2 instance. here i want to encrypt a root volume at the time of launch. its possible to create a separate EBS, encrypt it and attach it as boot volume. but i couldn't find a way to encrypt it while launching. any way to do this?Thanks In Advance

While the answer of Nate is correct, this would lead to a lot of code duplication. A better solution in my opinion would be to work with a list and loop over it.Create a variable (variable.tf file) that contains a list of possible folders:variable "s3_folders" {
type = "list"
description = "The list of S3 folders to create"
default = ["folder1", "folder2", "folder3"]
}Then alter the piece of code you already have:resource "aws_s3_bucket_object" "folders" {
count = "${length(var.s3_folders)}"
bucket = "${aws_s3_bucket.b.id}"
acl = "private"
key = "${var.s3_folders[count.index]}/"
source = "/dev/null"

A VPC range of10.0.0.0/16means that all addresses starting with10.0.x.xare part of the VPC.When you create the subnet, you want it to be aportionof the VPC. People typically assign an address like10.0.1.0/24-- the /24 means that the subnet has every IP address starting with10.0.1.x.The error you received is because you tried to make a /16 subnet within a /16 VPC. This will work (as it did in your 2nd try), but you can then only have one subnet.Bottom line:Use/24, or at least something smaller than/16(which in CIDR actually means a bigger number!).ShareFollowansweredJan 8, 2018 at 1:16John RotensteinJohn Rotenstein254k2626 gold badges408408 silver badges497497 bronze badges1Thanks mate, your answer was very helpful :)–VinoJan 8, 2018 at 1:18Add a comment|

I am trying to create a VPC with multiple subnets in AWS. I am pretty sure I am get the concepts of CIDR to mask networks and available hosts.Unfortunately, whenever I am trying to design the VPC I am getting errors. This is my VPC design:VPC: 10.0.0.0/16Public subnet 1: 10.0.1.0/16Error:Must be a valid CIDR block. Did you mean 10.0.0.0/16?Then I assign my Public subnet as 10.0.0.0/16 due to the error.Then I proceed to create my private network as 10.0.1.0/16 - I get an error:CIDR block 10.0.1.0/16 overlaps with pre-existing CIDR block 10.0.0.0/16What am I doing wrong? I just want to create two private network and one public network.
