= Removing an interface from nodes
|
|
|
|
Remove an interface from nodes by editing the `NodeNetworkConfigurationPolicy` object and set
|
|
the `state` of the interface to `absent`.
|
|
|
|
[NOTE]
|
|
====
|
|
Deleting the node network policy that added an interface does not change the configuration of the policy on the node.
|
|
Although a `NodeNetworkConfigurationPolicy` is an object in the cluster, it only represents the requested configuration. +
|
|
Similarly, removing an interface does not delete the policy.
|
|
====
|
|
|
|
.Procedure
|
|
|
|
. Update the `NodeNetworkConfigurationPolicy` manifest used to create the interface. The following example removes a Linux bridge:
|
|
+
|
|
[source,yaml]
|
|
----
|
|
apiVersion: nmstate.io/v1alpha1
|
|
kind: NodeNetworkConfigurationPolicy
|
|
metadata:
|
|
name: <br1-eth1-policy> <1>
|
|
spec:
|
|
nodeSelector: <2>
|
|
node-role.kubernetes.io/worker: "" <3>
|
|
desiredState:
|
|
interfaces:
|
|
- name: br1
|
|
type: linux-bridge
|
|
state: absent <4>
|
|
----
|
|
<1> Name of the policy.
|
|
<2> Optional: If you do not include the `nodeSelector` parameter, 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> Changing the state to `absent` removes the interface.
|
|
|
|
. Update the policy on the node and remove the interface:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc apply -f <br1-eth1-policy.yaml> <1>
|
|
----
|
|
<1> File name of the policy manifest.
