Unexpected behaviour of AWS ASG, AWS Launch Template within AWS EKS

I've created AWS EKS cluster, with managed node group(s), as well I've created an AWS ASG (Auto Scaling Group) and AWS Launch Template. But when I'm attaching an AWS Launch Template to managed EKS node groups, it is creating a duplicate of existing (created) AWS Launch Template

--

MANAGED AWS EC2 LT

Those Launch Templates:

DEV/MANAGED/EKS-WORKERS-SM/LATEST/TEMPLATE/EU-CENTRAL-1X

and

eks-XXXXXXXX-XXXXXXXX-XXXXXXXX

are identical, and I don't understand why EKS is creating for duplicates

--

As well same stuff is happening with AWS ASG (Auto Scaling Group), is there any way to fix this problem?

Technologies which used:

  • Terraform
    • Launch Template resource
    • Auto Scaling Group resource
    • EKS resource
    • EKS node group resource
terraform amazon-web-services amazon-ec2

It seems, you're running both resources. When you want to manage the Nodes only by your self, you don't need to have EKS node group resource, instead you need to use Launch Template resource with Auto Scaling Group resource, and with proper tagging
