machine-config-operator doesn't work on single node cluster #10

Thanks for your nice tutorial!

The machine-config-operator doesn't seem to work on a single node cluster. Do you know if there is a settings available to let the machine-config-operator work on a single node cluster?

Hi! Here is explanation in MCO docs about your problem.

https://github.com/openshift/machine-config-operator/blob/master/docs/SingleNodeOpenShift.md

When MCO is changing configuration of Red Hat CoreOS, machine-config-daemon need to apply this new configuration. But machine-config-controller does not issue the command to change, cause there is a condition exist in machine-config-pool "no more than one missing master". I talked with developers, and they says this problem is fixed already in OpenShift 4.8 version.

Thanks for the update!

I'll test it with ODK / OpenShift 4.8 when it becomes available...
