@maniappan Could you provide more details? Do you mean the existing instances? Or worker nodes? Have you deleted worker node group before you remove EKS cluster?

[Jeffwan]

Sorry for late response. I just come back from vacation.

I followed the uninstall instructions. There was some exception in the process, so wen ahead and removed the worker nodes and eks clusters. However the worker nodes were constantly spun up even after terminating.. whole sequence of shutdown process may have to be verified.

removed the worker nodes

How do you remove the nodes? from EC2? for Cloud Formation?

were constantly spun up

Sounds like the instances are still controlled by ASG? Have you deleted ASG?

[maniappan]

Deleted ec2, eks clusters and asg. Asg deletion was not happening due some circular dependendency.

Eksctl will delete worker node group cloud formation template first and then eks cluster cloud formation. EC2 instances will be delete along with ASG deletion.

If you delete ec2 separately, new instance will be created because ASG has to maintain at desired count.

Thanks, will it be possible to have the manual steps documented?.
