Description

Resources must not use the default namespace. This rule flags Kubernetes resources that either lack metadata or metadata.namespace, or have metadata.namespace set to default. It applies to resource kinds: kubernetes_ingress, kubernetes_config_map, kubernetes_secret, kubernetes_service, kubernetes_cron_job, kubernetes_service_account, kubernetes_role, kubernetes_role_binding, kubernetes_pod, kubernetes_deployment, kubernetes_daemonset, kubernetes_job, kubernetes_stateful_set, kubernetes_replication_controller.

Compliant Code Examples

resource "kubernetes_pod" "test3" {
  metadata {
    name = "terraform-example"
    namespace = "terraform-namespace"
  }
}

resource "kubernetes_cron_job" "test4" {
  metadata {
    name = "terraform-example"
    namespace = "terraform-namespace"
  }
}

Non-Compliant Code Examples

resource "kubernetes_pod" "test" {
  metadata {
    name = "terraform-example"
    namespace = "default"
  }
}

resource "kubernetes_cron_job" "test2" {
  metadata {
    name = "terraform-example"
  }
}
