10.9. Editing an additional network
As a cluster administrator you can modify the configuration for an existing additional network.
10.9.1. 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-adminprivileges.
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:
$ oc edit networks.operator.openshift.io cluster
-
In the
additionalNetworkscollection, 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
NetworkAttachmentDefinitionobject 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 theNetworkAttachmentDefinitionobject to reflect your changes.$ oc get network-attachment-definitions <network-name> -o yaml
For example, the following console output displays a
NetworkAttachmentDefinitionobject that is namednet1:$ oc get network-attachment-definitions net1 -o go-template='{{printf "%s\n" .spec.config}}' { "cniVersion": "0.3.1", "type": "macvlan", "master": "ens5", "mode": "bridge", "ipam": {"type":"static","routes":[{"dst":"0.0.0.0/0","gw":"10.128.2.1"}],"addresses":[{"address":"10.128.2.100/23","gateway":"10.128.2.1"}],"dns":{"nameservers":["172.30.0.10"],"domain":"us-west-2.compute.internal","search":["us-west-2.compute.internal"]}} }
