remote-state-setup

main.tf - You need to run this file once in order to create a bucket and a table for future use for a remote Terraform state.

root dir

• terraform.tf - Used to tell Terraform to use the bucket and table we created as a backend for the state file.
• main.tf - Defines the name of the cluster and region, selects 2 availability zones and creates 2 private subnets and 2 public ones. Also enabled nat gateway, marks public subnets for loab balancer and sets up an internal lb in the private subnets.
• eks-al2023.tf - Defines a cluster with t2.medium machines with al2023 image, with public access to the api, the current user becomes an admin of the cluster and we also define a shut down grace period (taken from the example).

non trivial stuff:

• cluster_endpoint_public_access = true was needed
• "kubernetes.io/cluster/eks-michaels" = "shared" public subnet tag was needed for lb to work
