QUESTION

Cloudformation Elasticbeanstalk specify target group for shared load balancer

Asked 2021-May-01 at 14:34

I have two Cloudformation templates

one which creates a VPC, ALB and any other shared resources etc.
one which creates an elastic beanstalk environment and relevant listener rules to direct traffic to this environment using the imported shared load balancer (call this template Environment)

The problem I'm facing is the Environment template creates a AWS::ElasticBeanstalk::Environment which subsequently creates a new CFN stack which contains things such as the ASG, and Target Group (or process as it is known to elastic beanstalk). These resources are not outputs of the AWS owned CFN template used to create the environment.

When setting

I don't have access as far as I can tell to the ARN of the target group created by the elastic beanstalk environment resource

That's true. The way to overcome this is through custom resource. In fact I developed fully working, very similar resource for one of my previous answers, thus you can have a look at it and adopt to your templates. The resource returns ARN of the EB load balancer, but you could modify it to get the ARN of EB's target group instead.

QUESTION

Pass variable from NodeJS runtime back into CloudFormation

Asked 2020-Dec-21 at 08:56

I have a CF template that uses a Serverless function in Javascript to instantiate an AWS Connect instance as there is no actual CF resource for Connect. I use environment variables to pass in values from CF into the inline Javascript. Now I need the reverse: to extract some of those values back out of JS and pass them back to other parts of the CF template. So, the question is, how do I pass a variable from Javascript to CloudFormation? I suspect I'll need to use something like the Systems Manager Parameter store but perhaps there's an easier way? Specifically I need the value "serviceRole" in the below snippet available to pass to other CF resources:

When sending the "SUCCESS" response to CloudFormation, you can use the Data field of the response object to pass the Service Role as a key-value pair. This way, all resources that are created after the Custom Resource can access this information using Fn::GetAtt. From the docs:

After getting a SUCCESS response, AWS CloudFormation proceeds with the stack operation. If a FAILED response or no response is returned, the operation fails. Any output data from the custom resource is stored in the pre-signed URL location. The template developer can retrieve that data by using the Fn::GetAtt function.

How to download a file from a url using AWS lambda with node.js code

Asked 2020-Jul-18 at 10:20

I am having a hard time to write code for my lambda function. This function has to download files into /tmp directory but instead of doing that it creates files with 0 size. The output looks like that:

You have to wait for the Writable Stream to fire the 'finish' event.

What is happening there is that the process terminates almost immediately because it never waits for the request.pipe(file) to be actually executed.

One strategy to do that involves 2 extra steps:

use async/awaits in loops (aka ECMAScript 2018 Asynchronous Iteration), something like:
