Chapter 7. Uninstalling CodeReady Workspaces

There is no dedicated function in the deploy.sh script to uninstall CodeReady Workspaces.

However, you can delete a custom resource, which deletes all the associated objects.

Note that in all the commands in this section, <OpenShift-project-name> is an OpenShift project with deployed CodeReady Workspaces (workspaces is the OpenShift project by default).

Procedure

  1. To delete CodeReady Workspaces and its components: 

    $ oc delete checluster/codeready -n=<OpenShift-project-name>
$ oc delete namespace -n=<OpenShift-project-name>
    Copy to Clipboard Toggle word wrap

    Use selectors to delete particular deployments and associated objects.

  2. To remove all CodeReady Workspaces server-related objects: 

    $ oc delete all -l=app=che -n=<OpenShift-project-name>
    Copy to Clipboard Toggle word wrap

  3. To remove all Keycloak-related objects: 

    $ oc delete all -l=app=keycloak -n=<OpenShift-project-name>
    Copy to Clipboard Toggle word wrap

  4. To remove all PostgreSQL-related objects: 

    $ oc delete all -l=app=postgres -n=<OpenShift-project-name>
    Copy to Clipboard Toggle word wrap

    PVCs, service accounts, and role bindings should be deleted separately because the oc delete all command does not delete them.

  5. To delete CodeReady Workspaces server PVC, ServiceAccount, and RoleBinding: 

    $ oc delete sa -l=app=che -n=<OpenShift-project-name>
$ oc delete rolebinding -l=app=che -n=<OpenShift-project-name>
$ oc delete pvc -l=app=che -n=<OpenShift-project-name>
    Copy to Clipboard Toggle word wrap

  6. To delete Keycloak and PostgreSQL PVCs: 

    $ oc delete pvc -l=app=keycloak -n=<OpenShift-project-name>
$ oc delete pvc -l=app=postgres -n=<OpenShift-project-name>
    Copy to Clipboard Toggle word wrap
