Uninstall Portworx from a Kubernetes cluster using the Operator

If you're using the Portworx Operator, you can uninstall Portworx by adding a delete strategy to your StorageCluster object, then deleting it. When uninstalling, you may choose to either keep the the data on your drives, or wipe them completely:

  • Uninstall: will remove the Kubernetes objects, Portworx systemctl service, /etc/pwx and /opt/pwx directories, and all traces of Portworx on the nodes. The drives will not be formatted and none the Portworx Metadata in the KVDB will be deleted. You may need to Uninstall Portworx if you installed Portworx in the wrong namespace.
  • Uninstall and wipe: will remove all of the resources listed in the "Uninstall" procedure, and also removes (formats) all data from your disks permanently, including the Portworx metadata. You may want to perform an uninstall and wipe when you decommission a cluster.

Prerequisites

  • You must already be running Portworx through the Operator, this method will not work for other Portworx deployments

Uninstall Portworx

  1. Enter the kubectl get command to display the name of your Portworx storage cluster and specify your namespace:

    kubectl get -n kube-system storagecluster <storagecluster-name>
  2. Enter the kubectl edit command to modify your storage cluster and specify your namespace:

    kubectl edit -n kube-system storagecluster <storagecluster-name>
  3. Modify your StorageCluster object, adding the deleteStrategy field with either the Uninstall or UninstallAndWipe type:

  • Uninstall Portworx only:

    apiVersion: core.libopenstorage.org/v1
    kind: StorageCluster
    metadata:
    name: portworx
    namespace: kube-system
    spec:
    deleteStrategy:
    type: Uninstall
  • Uninstall Portworx and wipe all drives:

    note

    Wipe operations remove all data from your disks permanently including the Portworx metadata, use caution when applying the DeleteStrategy spec.

    apiVersion: core.libopenstorage.org/v1
    kind: StorageCluster
    metadata:
    name: portworx
    namespace: kube-system
    spec:
    deleteStrategy:
    type: UninstallAndWipe
  1. Enter the kubectl delete command, specifying the name of your StorageCluster object and specify your namespace:

    kubectl delete StorageCluster <your-storagecluster-name> -n kube-system
    note

    This operation can take several minutes to complete.

  2. Delete the operator:

    kubectl delete deployment -n <namespace> portworx-operator
