Delete stateful workloads

This document explains how to delete existing stateful workloads running in a Google Distributed Cloud (GDC) air-gapped Kubernetes cluster. It's important to remove workloads that are no longer in use to maintain the health and performance of your Kubernetes cluster.

This document is for developers within the application operator group who are responsible for managing application workloads for their organization. For more information, see Audiences for GDC air-gapped documentation.

Before you begin

To complete the tasks in this document, you must request the necessary permissions and prepare your environment.

Request IAM roles

You must have specific roles to get the permissions you need to delete stateful workloads. The roles you require depend on whether you are working within an organization-scoped shared cluster or project-scoped standard cluster. For more information, see Kubernetes cluster configurations.

Shared cluster roles

To create, delete, edit, or view stateful workloads in a shared cluster, ask your Project IAM Admin to grant you the Namespace Admin (namespace-admin) role. This role is bound to your project namespace.

Standard cluster roles

To create, delete, edit, or view stateful workloads in a standard cluster, ask your Project IAM Admin to grant you the Cluster Developer (cluster-developer) role. This role is bound to your project namespace.

Prepare your environment

To run commands against a Kubernetes cluster using the API, make sure you have the following resources:

  • Locate the Kubernetes cluster name, or ask a member of the platform administrator group what the cluster name is.

  • Sign in and generate the kubeconfig file for the Kubernetes cluster.

  • Use the kubeconfig path of the Kubernetes cluster to replace KUBERNETES_CLUSTER_KUBECONFIG in these instructions.

Delete a StatefulSet resource

Delete a StatefulSet resource if you no longer have a use for its associated stateful container workloads.

  1. To delete a StatefulSet resource, run:

    kubectl --kubeconfig KUBERNETES_CLUSTER_KUBECONFIG \
    -n NAMESPACE \
    delete statefulset STATEFULSET_NAME

    Replace the following:

    • KUBERNETES_CLUSTER_KUBECONFIG: the kubeconfig file for the cluster.

    • NAMESPACE: the namespace of the container workload. For shared clusters, this must be a project namespace. For standard clusters, it can be any namespace.

    • STATEFULSET_NAME: the name of the StatefulSet object to delete.

    When deleting a StatefulSet resource, all of its pods are also deleted. If you prefer to only delete the StatefulSet resource and not its pods, include the --cascade=orphan parameter.

  2. Delete the associated service:

    kubectl --kubeconfig KUBERNETES_CLUSTER_KUBECONFIG \
    delete service SERVICE_NAME

    Replace the following variables:

    • KUBERNETES_CLUSTER_KUBECONFIG: the kubeconfig file for the cluster.

    • SERVICE_NAME: the name of the Service object to delete.
