= Removing the {devworkspace-op}
|
|
|
|
To completely uninstall the web terminal, you must also remove the {devworkspace-op} and custom resources used by the Operator.
|
|
|
|
[IMPORTANT]
|
|
====
|
|
The {devworkspace-op} is a standalone Operator and may be required as a dependency for other Operators installed in the cluster. Follow the steps below only if you are sure that the {devworkspace-op} is no longer needed.
|
|
====
|
|
|
|
.Prerequisites
|
|
|
|
* You have access to an {product-title} cluster with cluster administrator permissions.
|
|
* You have installed the `oc` CLI.
|
|
|
|
// Hide step 2, cannot delete resource "customresourcedefinitions" in ROSA/OSD
|
|
// Hide step 4, cannot delete resource "mutatingwebhookconfigurations" in ROSA/OSD, do not delete deployment/devworkspace-webhook-server, see NOTE
|

.Procedure
|
|
|
|
. Remove the `DevWorkspace` custom resources used by the Operator, along with any related Kubernetes objects:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc delete devworkspaces.workspace.devfile.io --all-namespaces --all --wait
|
|
----
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc delete devworkspaceroutings.controller.devfile.io --all-namespaces --all --wait
|
|
----
|
|
+
|
|
[WARNING]
|
|
====
|
|
If this step is not complete, finalizers make it difficult to fully uninstall the Operator.

|
|
. Remove the CRDs used by the Operator:
|
|
+
|
|
[WARNING]
|
|
====
|
|
The DevWorkspace Operator provides custom resource definitions (CRDs) that use conversion webhooks. Failing to remove these CRDs can cause issues in the cluster.
|
|
====
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc delete customresourcedefinitions.apiextensions.k8s.io devworkspaceroutings.controller.devfile.io
|
|
----
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc delete customresourcedefinitions.apiextensions.k8s.io devworkspaces.workspace.devfile.io
|
|
----
|

[source,terminal]
|

$ oc delete customresourcedefinitions.apiextensions.k8s.io devworkspacetemplates.workspace.devfile.io
|
|
----
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc delete customresourcedefinitions.apiextensions.k8s.io devworkspaceoperatorconfigs.controller.devfile.io
|
|
----
|
|
|
|
. Verify that all involved custom resource definitions are removed. The following command should not display any output:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc get customresourcedefinitions.apiextensions.k8s.io | grep "devfile.io"
|
|
----
|
|
|
|
. Remove the `devworkspace-webhook-server` deployment, mutating, and validating webhooks:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc delete deployment/devworkspace-webhook-server -n openshift-operators
|
|
----
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc delete mutatingwebhookconfigurations controller.devfile.io
|
|
----
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc delete validatingwebhookconfigurations controller.devfile.io
|
|
----
|
|
+
|
|
[NOTE]
|
|
====
|
|
If you remove the `devworkspace-webhook-server` deployment without removing the mutating and validating webhooks, you can not use `oc exec` commands to run commands in a container in the cluster. After you remove the webhooks you can use the `oc exec` commands again.

. Remove any remaining services, secrets, and config maps. Depending on the installation, some resources included in the following commands may not exist in the cluster.

|
.. Scroll the filter list or type a keyword into the *Filter by name* box to find the {devworkspace-op}.
|
|
.. Click the Options menu {kebab} for the Operator, and then select *Uninstall Operator*.
|
|
.. In the *Uninstall Operator* confirmation dialog box, click *Uninstall* to remove the Operator, Operator deployments, and pods from the cluster. The Operator stops running and no longer receives updates.
