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>

    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>

  3. To remove all Keycloak-related objects: 

    $ oc delete all -l=app=keycloak -n=<OpenShift-project-name>

  4. To remove all PostgreSQL-related objects: 

    $ oc delete all -l=app=postgres -n=<OpenShift-project-name>

    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>

  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>
