= Removing an additional network attachment definition
|
|
|
|
As a cluster administrator, you can remove an additional network from your
|
|
{product-title} cluster. The additional network is not removed from any pods it
|
|
is attached to.
|
|
|
|
.Prerequisites
|
|
|
|
* Install the OpenShift CLI (`oc`).
|
|
* Log in as a user with `cluster-admin` privileges.
|
|
|
|
.Procedure
|
|
|
|
To remove an additional network from your cluster, complete the following steps:
|
|
|
|
. Edit the Cluster Network Operator (CNO) in your default text editor by running
|
|
the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc edit networks.operator.openshift.io cluster
|
|
----
|
|
|
|
. Modify the CR by removing the configuration from the `additionalNetworks`
|
|
collection for the network attachment definition you are removing.
|
|
+
|
|
[source,yaml]
|
|
----
|
|
apiVersion: operator.openshift.io/v1
|
|
kind: Network
|
|
metadata:
|
|
name: cluster
|
|
spec:
|
|
additionalNetworks: [] <1>
|
|
----
|
|
<1> If you are removing the configuration mapping for the only additional
|
|
network attachment definition in the `additionalNetworks` collection, you must
|
|
specify an empty collection.
|
|
|
|
. Save your changes and quit the text editor to commit your changes.
|
|
|
|
. Optional: Confirm that the additional network CR was deleted by running the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc get network-attachment-definition --all-namespaces
