To be use with gitops-bridge project, see example here

Usage

locals {
  name                   = "ex-${replace(basename(path.cwd), "_", "-")}"
  environment            = "dev"
  cluster_version        = "1.27"
  gitops_addons_url      = "https://github.com/gitops-bridge-dev/gitops-bridge-argocd-control-plane-template"
  gitops_addons_basepath = ""
  gitops_addons_path     = "bootstrap/control-plane/addons"
  gitops_addons_revision = "HEAD"

  oss_addons = {
    enable_argo_workflows = true
    enable_foo                                   = true # you can add any addon here, make sure to update the gitops repo with the corresponding application set
  }
  addons = merge(local.oss_addons, { kubernetes_version = local.cluster_version })

  addons_metadata = merge(
    {
      addons_repo_url      = local.gitops_addons_url
      addons_repo_basepath = local.gitops_addons_basepath
      addons_repo_path     = local.gitops_addons_path
      addons_repo_revision = local.gitops_addons_revision
    }
  )

  argocd_apps = {
    addons = file("${path.module}/bootstrap/addons.yaml")
