= Creating an interface on nodes
|
|
|
|
Create an interface on nodes in the cluster by applying a `NodeNetworkConfigurationPolicy` manifest to the cluster. The manifest details the requested configuration for the interface.
|
|
|
|
By default, the manifest applies to all nodes in the cluster. To add the interface to specific nodes, add the `spec: nodeSelector` parameter and the appropriate `<key>:<value>` for your node selector.
|
|
|
|
.Procedure
|
|
|
|
. Create the `NodeNetworkConfigurationPolicy` manifest. The following example configures a Linux bridge on all worker nodes:

[source,yaml]

<2> Optional. If you do not include the `nodeSelector`, the Policy applies to all nodes in the cluster.
|
|
<3> This example uses the `node-role.kubernetes.io/worker: ""` node selector to select all worker nodes in the cluster.
|
|
<4> Optional. Human-readable description for the interface.
|
|
|
|
. Create the Policy:

|
|
$ oc apply -f <br1-eth1-policy.yaml> <1>
