When you copy the config.yaml from defaults and do not configure ingress, the microshift will fail to start with error:

Jun 13 20:43:24 node-0 microshift[8824]: ??? E0613 20:43:24.440185    8824 run.go:74] "command failed" err="invalid configuration: error validating ingress.listenAddress: interface  not present in the host"

- copy the config.yaml from default, do not fill in "ingress.listenAddress.

1.
2.
3.

- improvement should be that when config.yaml.defaults will be created, the listenAddress will be propagated from the current host
- put this in the docs as requirement or set the microshift to ignore that value and take default interface (based on default route) as listenAddress
