= Installing the Multus CNI plugin on a running node
|
|
|
|
[role="_abstract"]
|
|
If you want to attach additional networks to a pod for high-performance network configurations, you can install the {microshift-short} Multus RPM package. After installation, a host restart is required to re-create all the pods with the Multus annotation.
|
|
|
|
[IMPORTANT]
|
|
====
|
|
Uninstalling the Multus CNI plugin is not supported.
|
|

|
|
.Prerequisites
|
|
|
|
* You have root access to the host.
|
|
|
|
.Procedure
|
|
|
|
. Install the Multus RPM package by running the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ sudo dnf install microshift-multus
|

|

|
|
[TIP]
|
|
====
|
|
If you create your custom resources (CRs) for additional networks now, you can complete your installation and apply configurations with one restart.
|
|
====
|
|
|
|
. To apply the package manifest to an active node, restart the host by running the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ sudo systemctl restart
|
|
----
|
|
|
|
.Verification
|
|
|
|
* After restarting, ensure that the Multus CNI plugin components are created by running the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc get pod -A | grep multus
|
|
----
|

|
|
. Deploy your applications that use the created CRs. |
