v0.12.5

What's Changed

• Fix index on wrong level of module by @thepoppingone in #58

Tested to upgrade Essential submodule without state migration, the helm chart would error out due to the change in the IRSA role and its SA. Will need to delete pods manually to reload the SA role ARN.

Full Changelog: v0.12.3...v0.12.4

v0.12.3

What's Changed

• Karpenter submodule by @thepoppingone in #52
• Cluster Autoscaler is part of Essentials submodule but Karpenter exists as its own submodule

State Migration (Optional but recommended)

• As autoscaler resources on EKS Essentials submodule are now optionally created, but created by default, when anyone upgdares to v0.12.3 the state is changed from helm_release.cluster_autoscaler to helm_release.cluster_autoscaler[0], module.cluster_autoscaler_irsa_role is also changed module.cluster_autoscaler_irsa_role[0].
• If you do not do the migration, the resources will be recreated, which might cause some errors but on re apply it should go away (untested)

Additional fields if using Karpenter submodule

• As Karpenter submodule uses fargate-profile submodule to deploy Karpenter in Fargate, it requires fargate roles arns to be added to the aws-auth for pods to start properly

You have to add this in the locals section when installing EKS main module

autoscaling_mode                                 = "karpenter"
  aws_auth_fargate_profile_pod_execution_role_arns = local.autoscaling_mode == "karpenter" ? concat(values(module.karpenter.fargate_profile_pod_execution_role_arn)) : []
  additional_role_mapping = local.autoscaling_mode == "karpenter" ? [
    {
      rolearn = module.eks.worker_iam_role_arn
      groups = [
        "system:bootstrappers",
        "system:nodes",
      ]
      username = "system:node:{{EC2PrivateDNSName}}"
    }
  ] : []

And update the role_mapping attribute to the following:

role_mapping = concat([
    for role in local.eks_master_roles :
    {
      rolearn  = role.arn
      groups   = ["system:masters"]
      username = role.user
    }
  ], local.additional_role_mapping)

And aws_auth_fargate_profile_pod_execution_role_arns, note the values() should contain the fargate_profile arns map if there are any fargate-profiles used in the existing cluster

aws_auth_fargate_profile_pod_execution_role_arns = concat(values({}), local.aws_auth_fargate_profile_pod_execution_role_arns)

Karpenter Submodule

Lastly, to install Karpenter submodule.

module "karpenter" {
  source  = "SPHTech-Platform/eks/aws//modules/karpenter"
  version = "~> 0.12.0"

  source = "git::https://github.com/SPHTech-Platform/terraform-aws-eks.git//modules/karpenter?ref=karpenter"

  karpenter_chart_version = "v0.27.5"

  cluster_name        = local.cluster_name
  cluster_endpoint    = data.aws_eks_cluster.this.endpoint
  oidc_provider_arn   = module.eks.oidc_provider_arn
  worker_iam_role_arn = module.eks.worker_iam_role_arn

  autoscaling_mode = local.autoscaling_mode
  
 # Required for Fargate profile
  subnet_ids = local.app_subnets

 # Add the provisioners and nodetemplates after CRDs are installed
  # karpenter_provisioners  = local.karpenter_provisioners
  # karpenter_nodetemplates = local.karpenter_nodetemplates

}
