Script to create a RHCOS custom image containing a NetworkManager rpm from
a copr repository.
In order to have a custom RHCOS image, we cannot modify the image itself but
we can add a custom layered image that includes all RHCOS functionality and
adds additional functionality to it.
Requirements:
- A quay.io registry where you have push access.
- You must have your pull-secret in the same directory where the script is
being run. You can download your pull-secret from:
https://console.redhat.com/openshift/install/pull-secret
In order to install this on nodes from a cluster that already exists it must
be done using MachineConfig operator. In essence the following YAML file
must be created.
```
apiVersion: machineconfiguration.openshift.io/v1
kind: MachineConfig
metadata:
labels:
machineconfiguration.openshift.io/role: <role>
name: os-layer-custom-nm
spec:
osImageURL: <registry>
```
Please, notice that the role and registry need to be set to your needs.
Then, it can be applied by:
$ oc create -f <yaml file>
Finally, the machines will be ready once the field UPDATED has the True value
in the output of this command.
$ oc get mcp
