= Modifying an additional network attachment definition
|
|
|
|
As a cluster administrator, you can make changes to an existing additional
|
|
network. Any existing pods attached to the additional network will not be updated.
|
|
|
|
.Prerequisites
|
|
|
|
* You have configured an additional network for your cluster.
|
|
* Install the OpenShift CLI (`oc`).
|
|
* Log in as a user with `cluster-admin` privileges.
|
|
|
|
.Procedure
|
|
|
|
To edit an additional network for your cluster, complete the following steps:
|
|
|
|
. Run the following command to edit the Cluster Network Operator (CNO) CR in
|
|
your default text editor:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc edit networks.operator.openshift.io cluster
|
|
----
|
|
|
|
. In the `additionalNetworks` collection, update the additional network with
|
|
your changes.
|
|
|
|
. Save your changes and quit the text editor to commit your changes.
|
|
|
|
. Optional: Confirm that the CNO updated the `NetworkAttachmentDefinition` object by running the following command. Replace `<network-name>` with the name of the additional network to display. There might be a delay before the CNO updates the `NetworkAttachmentDefinition` object to reflect your changes.
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc get network-attachment-definitions <network-name> -o yaml
|
|
----
|
|
+
|
|
For example, the following console output displays a `NetworkAttachmentDefinition` object that is named `net1`:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc get network-attachment-definitions net1 -o go-template='{{printf "%s\n" .spec.config}}'
