= Creating an OVN-Kubernetes configuration file
|
|
|
|
{microshift-short} uses built-in default OVN-Kubernetes values if an OVN-Kubernetes configuration file is not created. You can write an OVN-Kubernetes configuration file to `/etc/microshift/ovn.yaml`. An example file is provided for your configuration.
|
|
|
|
.Procedure
|
|
|
|
. To create your `ovn.yaml` file, run the following command:
|
|
+
|
|
[source, yaml]
|
|
----
|
|
$ sudo cp /etc/microshift/ovn.yaml.default /etc/microshift/ovn.yaml
|
|
----
|
|
|
|
. To list the contents of the configuration file you created, run the following command:
|
|
+
|
|
[source, yaml]
|
|
----
|
|
$ cat /etc/microshift/ovn.yaml
|
|

|
|
[source,yaml]
|
|
----
|
|
mtu: 1400
|
|
