= Uninstalling the Kubernetes NMState Operator
|
|
|
|
You can use the {olm-first} to uninstall the Kubernetes NMState Operator, but by design {olm} does not delete any associated custom resource definitions (CRDs), custom resources (CRs), or API Services.
|
|
|
|
Before you uninstall the Kubernetes NMState Operator from the `Subcription` resource used by {olm}, identify what Kubernetes NMState Operator resources to delete. This identification ensures that you can delete resources without impacting your running cluster.
|
|
|
|
If you need to reinstall the Kubernetes NMState Operator, see "Installing the Kubernetes NMState Operator by using the CLI" or "Installing the Kubernetes NMState Operator by using the web console".
|
|
|
|
.Prerequisites
|
|
|
|
* You have installed the {oc-first}.
|
|
* You have installed the `jq` CLI tool.
|
|
* You are logged in as a user with `cluster-admin` privileges.
|
|
|
|
.Procedure
|
|
|
|
. Unsubscribe the Kubernetes NMState Operator from the `Subcription` resource by running the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc delete --namespace openshift-nmstate subscription kubernetes-nmstate-operator
|
|
----
|
|
|
|
. Find the `ClusterServiceVersion` (CSV) resource that associates with the Kubernetes NMState Operator:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc get --namespace openshift-nmstate clusterserviceversion
|
|
----
|
|
+
|
|
.Example output that lists a CSV resource
|
|
[source,terminal]
|
|
----
|
|
NAME DISPLAY VERSION REPLACES PHASE
|
|
kubernetes-nmstate-operator.v4.21.0 Kubernetes NMState Operator 4.21.0 Succeeded
|
|
----
|
|
|
|
. Delete the CSV resource. After you delete the file, {olm} deletes certain resources, such as `RBAC`, that it created for the Operator.
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc delete --namespace openshift-nmstate clusterserviceversion kubernetes-nmstate-operator.v4.21.0
|
|
----
|
|
|
|
. Delete the `nmstate` CR and any associated `Deployment` resources by running the following commands:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc -n openshift-nmstate delete nmstate nmstate
|
|
----
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc delete --all deployments --namespace=openshift-nmstate
|
|
----
|
|
|
|
. After you deleted the `nmstate` CR, remove the `nmstate-console-plugin` console plugin name from the `console.operator.openshift.io/cluster` CR.
|
|
+
|
|
.. Store the position of the `nmstate-console-plugin` entry that exists among the list of enable plugins by running the following command. The following command uses the `jq` CLI tool to store the index of the entry in an environment variable named `INDEX`:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
INDEX=$(oc get console.operator.openshift.io cluster -o json | jq -r '.spec.plugins | to_entries[] | select(.value == "nmstate-console-plugin") | .key')
|
|
----
|
|
+
|
|
.. Remove the `nmstate-console-plugin` entry from the `console.operator.openshift.io/cluster` CR by running the following patch command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc patch console.operator.openshift.io cluster --type=json -p "[{\"op\": \"remove\", \"path\": \"/spec/plugins/$INDEX\"}]" <1>
|
|
----
|
|
<1> `INDEX` is an auxiliary variable. You can specify a different name for this variable.
|
|
|
|
. Delete all the custom resource definitions (CRDs), such as `nmstates.nmstate.io`, by running the following commands:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc delete crd nmstates.nmstate.io
|
|
----
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc delete crd nodenetworkconfigurationenactments.nmstate.io
|
|
----
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc delete crd nodenetworkstates.nmstate.io
|
|
----
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc delete crd nodenetworkconfigurationpolicies.nmstate.io
|
|
----
|
|
|
|
. Delete the namespace:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc delete namespace openshift-nmstate
|
|
