Getting error while creating ekscluster with the same name

Question

I have created ekscluster with a name called "prod". I worked on this "prod" cluster after that i have deleted it. I have deleted all its associated vpc, interfaces, security groups everything. But if i try to create the ekscluster with the same name "prod" am getting this below error. Can you please help me on this issue?

Answer 1

There are two things to consider here.

1. The delete command does not wait for all the resources to actually be gone. You should add the --wait flag in order to let it finish. It usually it takes around 10-15 mins.

2. If that is still not enough you should make sure that you delete the CloudFormation object. It would look something like this (adjust the naming):

   #delete cluster: -delete cloudformation stack aws cloudformation list-stacks --query StackSummaries[].StackName aws cloudformation delete-stack --stack-name worker-node-stack aws eks delete-cluster --name EKStestcluster

Please let me know if that helped.

Answer 2

I was struggling with this error while Running EKS via Terraform - I'll share my solution hopefully it will save other some valuable time.

I tried to follow the references below but same result.

Also I tried to setup different timeouts for delete and create - still didn't help.

Finally I was able to resolve this when I changed the create_before_destroy value inside the lifecycle block to false:

  lifecycle {
    create_before_destroy = false
  }

(*) Notice - pods are still running on cluster during the update.
