CloudFormation: stack is stuck, CloudTrail events shows repeating DeleteNetworkInterface event

Question

I am deploying a stack with CDK. It gets stuck in CREATE_IN_PROGRESS . CloudTrail logs show repeating events in logs:

DeleteNetworkInterface CreateLogStream

What should I look at next to continue debugging? Is there a known reason for this to happen?

Answer 1

I also saw the exact same issue with the deployment of a CDK-based ECS/Fargate Deployment

In my instance, I was able to diagnose the issue by following the content from the AWS support article https://aws.amazon.com/premiumsupport/knowledge-center/cloudformation-stack-stuck-progress/

What specifically diagnosed and then resolved it for me:-

• I updated my ECS service to set the desired task count of the ECS Service to 0. At that point the Cloud Formation stack did complete successfully.
• From that, it became obvious that the actual issue was related to the creation of the initial task for my ECS Service. I was able to diagnose that by reviewing the output in Deployment and Events Tab of the ECS Service in the AWS Management Console . In my case, the task creation was failing because of an issue with accessing the associated ECR repository. Obviously there could be other reasons but they should show-up there.
