Propagate Tags AWS EKS

Question

I'm using Terraform to deploy my infrastructure, and i would like to know if there is a way to propagate my EKS tags to any resources that it create (EC2, SG, ELB, EBS...)?

for the the moment i use this in Terraform to tag all my resources:

default_tags {
    tags = {
      Environment = "Prod"
      Project     = "my project"
    }

But all the resources created by EKS, or by the node groups are not tagged with those. Someone know how to manage this?

Thanks a lot for your help.

Answer 1

You can create a map variable called tags and refer to that variable in any resource you want to add those tags in.

variable "global_tags" {
  description = "A mapping of tags to assign to multiple aws resources"
  default     = {}
}
global_tags = {
    Terraform_Managed = "true"
    Environment = "prod"
}
