Issues solved. No need to archive deps when using cdk. Original issue was psycopg2 build not being compatible with the lambda env.
Installed dependancies herelayers/python/lib/python3.7/site-packages/
Layer
const layer = new LayerVersion(this, 'FunctionLayer',{
code: Code.fromAsset(path.join(__dirname, '../../../layers')),
compatibleRuntimes: [Runtime.PYTHON_3_7]
});basic bash script to install deps for python runtime version
rm -rf .venv
rm -rf ../layers/python/lib/python3.7/site-packages
mkdir -p ../layers/python/lib/python3.7/site-packages
pipenv install
cp -a .venv/lib/python3.7/site-packages/. ../layers/python/lib/python3.7/site-packages/
rm -rf .venv(.venv needs to be removed from functions dir or will cause cdk stack deployment to fail)
I'm trying to do something that might be against cdk design
I have aws sam apps creating their own resources
And in my cdk I want to discover those resources somehow (specifically, lambda functions, ddb tables, apigs etc)
So I can created some cw alarms for them
hi guys :) i did some research but didnt find anything in the docs. my question is if ResultSelector (in stepfunctions, task) is also able to return only a value instead a key/value pair. to show an example:
"ResultSelector": {
"Payload.$": "$.Payload"
}this generates always a new object with property "Payload" but i would actualy like to have all children from "$.Payload" into a new object (without declaring all children-key one by one)

I want to integrate greedy path variable to a route in Apigatwayv2, someone knows how to?
Like is show here: https://docs.aws.amazon.com/apigateway/latest/developerguide/http-api-develop-routes.html
Hello - is it possible to have a resource wait for a specific status / condition of another resource before deploying?
For instance the code below fails:
export class GameliftBuildStack extends cdk.Stack {
public readonly build: gamelift.CfnBuild
public readonly fleet: gamelift.CfnFleet
constructor(scope: cdk.App, id: string, props: BuildProps) {
super(scope, id, props)
this.build = new gamelift.CfnBuild(this, `build`, {
name: 'abuild',
version: '1.0'
operatingSystem: 'AMAZON_LINUX_2'
})
this.fleet = new gamelift.CfnFleet(this, `fleet`, {
name,
buildId: build.ref,
ec2InstanceType: 'c5.large'
})
}
}Because the build takes some indefinite period of time to move into READY status. Error message:
CREATE_FAILED | AWS::GameLift::Fleet | fleet (fleet) Invalid Build status 'INITIALIZED' for build-id build-fc47d982-0ee8-4fd5-b15b-d798652ec5be. Must be : READY (Service: AmazonGameLift; Status Code: 400; Error Code: InvalidRequestException; Request ID: 1090b109-6a30-47be-89dd-32fd1000fde9; Proxy: null)Does this need to be run as a 1-2 step process or can we add some sort of conditional wait step ie if build.status === 'READY' else wait?

Does anyone know if it is possible to use CDK to attach a CloudWatch metric to an existing resource (one which was already provisioned manually in AWS). I want to define a bunch of metrics and alarms for resources which already exist.
I can imagine running a separate SDK script on the account to attach the metrics to the resources, after running the CDK deploy. However if possible I would rather keep this all in CDK, to avoid having to write a bunch of resource lookups in SDK and then deploy across accounts.
As an example this code runs fine:
`let testMetric = new cloudwatch.Metric({
metricName: "CPU Test",
namespace: "Example namespace",
period: cdk.Duration.minutes(1) // duration of one minute.
});
let instance = new ec2.Instance(this, "Example", {
instanceType: new ec2.InstanceType("t2.micro"),
machineImage: ec2.MachineImage.latestAmazonLinux(),
vpc: new ec2.Vpc(this, "vpc")
});
testMetric.attachTo(instance); `However, when I attempt to attempt to replace instance with the result of a from... call (such as fromFargateServiceAttributes, which returns an IBaseService, it fails because an IBaseService is not a Construct

I<someClass> vs. <someClass>. Often if you cast the I<someClass> to <someClass> it'll fix your problem. Sometimes it won't, but most of the time it works. Example: const ddbArn = StackValueShare.getOtherStackOutput(this, mangledStackName + userDbStackSuffix, 'userDevicesTableArn');
const userTable = dynamodb.Table.fromTableArn(this, 'importedUserTable', ddbArn.toString()) as dynamodb.Table;fromXXX issues. In fact I am now creating some Constructs that do it for you. You'll note in the code example that I have a naming convention for stack exports, because stack exports are in a global namespace. You can see a working example that exports/imports a VPC at https://github.com/pszabop/cdk-vpc-export-import
Hey folks, I was playing around with the python cdk library for EC2 image builder. I'm working off an example provided by a tutorial from the AWS youtube channel (code src: https://github.com/kreuzhofer/CDKImagebuilderWindowsPipeline/blob/master/cdk/cdk/cdk_stack.py).
In building my stack, when I define pieces like the Infrastructure or Distribution Configuration, I follow the example and give it a name field like so https://github.com/kreuzhofer/CDKImagebuilderWindowsPipeline/blob/master/cdk/cdk/cdk_stack.py#L52.
When I try to synth my stack; however, it errors out saying
TypeError: __init__() got an unexpected keyword argument 'name'When I remove it, it synthesizes fine but when I deploy, the Cfn run complains at the resource and fails because
Model validation failed (#: required key [Name] not found)looking at the docs, it seems like the name isn't an inputtable parameter, and CDK or the resulting CFN does nothing to automatically generate anything in its stead. Wondering if anybody's had this experience before either with the image builder library specifically or with any other cdk service library?
Thanks!

Good day!
Will someone be so kind to explain why 'cfn-init.ts' removes duplicate command keys:
https://github.com/aws/aws-cdk/blob/0d7ca63edb11a80440732d6327d0fe3ed685a993/packages/%40aws-cdk/aws-ec2/lib/cfn-init.ts#L278
This makes it hard to run docker container with multiple mounts.
In the following example the second occurrence of '--mount' is skipped
ec2.InitCommand.argvCommand([
'docker', 'run', '-d',
'--mount', 'type=bind,source=/tmp/1,target=/tmp/1',
'--mount', 'type=bind,source=/tmp/2,target=/tmp/2',
'my-registry/my-image:0.0.1'
]);
You must provide a role to allow Amazon Cognito to send SMS messages and it gives me a role that it wants me to assign to the group but I want to create/assign that role in my CDK template.

This is sorta working for me. My lambda's log events are sent to a kinesis firehose stream to a S3 bucket.
new logs.SubscriptionFilter(this, 'SubscriptionFilter', {
logGroup: this.lambdaFn.logGroup,
destination: new FirehoseDestination(deliveryStream),
filterPattern: logs.FilterPattern.literal('appMonitoring'),
})But the file in the S3 bucket seems to contain encrypted data:
1f8b 0800 0000 0000 0000 e597 df6f e336

No idea why it's happening. I'm using only server side generated key.
