QUESTION
I started using CloudFormation Modules in my templates as a way to promote reuse and company best practices. I created a couple of modules as a proof-of-concept, which appeared in the CloudFormation Registry in AWS Console as expected.
The problem I'm having is that I would like to delete these test modules and build the real ones. I can't seem to find a way to do this, or even any documentation stating that it's not possible and why not. Is this possible, if so how?
The steps I ran to create/register the module are described here:

QUESTION
I am trying to define an AWS Batch Compute Environment with type 'FARGATE' from the Python AWS CDK, but it doesn't seem to be available. This is what I have so far:
...ANSWER
Answered 2021-Jun-07 at 05:17ComputeEnvironment
is Level 2 construct (high level) and as you pointed out it does not support Fargate. But if you go to Level 1 construct CfnComputeEnvironment you can do this.
The reason is that it directly maps to CloudFormation's AWS::Batch::ComputeEnvironment which you linked in your question.
QUESTION
There is a similar question but it does not use AWS::ApiGatewayV2::Stage
, and I need the AutoDeploy
that only the V2 seems to provide.
How do I enable CloudWatch logs and log full message data (as per the image) using CloudFormation in an AWS API Gateway?
I can't find anything at the documentation for the Stage https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-apigatewayv2-stage.html#cfn-apigatewayv2-stage-deploymentid
I am using an autodeployed stage. I am able to create the log groups, the IAM role to write logs in CloudWatch, but I can't enable the logging itself.

You can't. Execution logs are not supported by HTTP API (i.e. ApiGatewayV2) as explained by AWS here:
HTTP APIs currently support access logging only, and logging setup is different for these APIs. For more information, see Configuring logging for an HTTP API.

QUESTION
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
...ANSWER
Answered 2021-Apr-30 at 01:10I 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.

I am using AWS CloudFormation (YAML-based) to deploy an IAM role. This role should both be allowed to deploy other CloudFormation resources and to have the root of the AWS account it gets deployed into as a trusted entity.

QUESTION
I changed the status code for the health check from 200 to 302. After which the Target group turned to a healthy state. I wasn't able to get the healthy state with the 200 code. But when I try to access the DNS of the ALB. It times out and haven't been able to figure out why?
The ecs drupal instances logs provide these outputs "GET / HTTP/1.1" 302 573 "-" "ELB-HealthChecker/2.0" drupal
Any help would be much appreciated
...ANSWER
Answered 2021-Apr-25 at 11:07Based on the comments.
The template is fine. The ALB does not work because it is placed in private subnets along with ECS service. Assuming that private subnets are correctly setup to work with NAT gateway and access the internet, the following should be made:
- Place ALB in public subnets - it must be there, as otherwise it will no be accessible from the internet.
Also double check all the route tables for NAT, public subnets, internet gateway.

I have this template code that I'm trying to implement to my ElasticBeanStalk app but it's referencing to my default vpc and I can't find how I can reference my own VPC not the default one. This is my YAML code: (I just need to know how to reference my VpcID)
I tried to add some lines that I found in aws resources but they're not working: (each one in alone I did not use them together)

QUESTION
I am trying to create an ECS blue/green deployment setup by CloudFormation. I came across this documentation which mentions that ECS blue/green deployments can be be handled by CloudFormation without needing to explicitly create the CodeDeploy application and deployment groups.
Reference:
https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/blue-green.html
https://docs.aws.amazon.com/codedeploy/latest/userguide/deployments-create-ecs-cfn.html
It mentions that blue/green deployments are triggered only if one of the following resources needs to be re-created:
- AWS::ECS::TaskDefinition
- AWS::ECS::TaskSet
My question is that, if my docker image does not change (as it always have the version "latest"), the task definition suppose will not change, then how can I trigger the CloudFormation ECS blue/green deployments?
...ANSWER
Answered 2021-Apr-11 at 07:58The desired behavior currently cannot be achieved with ECS blue/green deployment setup by CloudFormation, since we cannot trigger a task definition change without updating the docker image tag.
An alternative would be using an explicit CodeDeploy application to handle the ECS blue/green deployment.
In the CodePipeline build phase, it can optionally update the docker image tag and create an "imageDetail.json" which specifies the image URI. In the deploy phase, CodeDeploy will update the taskdef.json with the image URI, thus creating a new task definition. This will in turn update the appspec.yaml with the updated task definition. This will then trigger the ECS blue/green deployment using the updated task definition and docker image.
I have put the relevant sample CloudFormation templates on GitHub for refernece. Most of the infrastructure creation can be streamlined with CloudFormation, except for the creation for CodeDeploy deployment groups. CloudFormation has not supported the creation of blue/green deployment groups yet, thus we have to create it with CLI.
