Okd: Ability to use a image mirror is broken in Beta 6

Created on 1 Jul 2020 · 5Comments · Source: openshift/okd

If we use a image mirror on Beta 6, the bootstrap does not complete.

The bootstrap node is up and running, but the machine-config-server pod on the bootstrap node continuously throws the following error:

I0630 18:45:36.895271       1 api.go:111] Pool master requested by address:"10.0.0.10:46408" User-Agent:"Ignition/2.3.0"

All files, directories and links must specify a unique `path`.

This results in a HTTP 500 error on the machine config server.

I think we either need to remove the duplicate entry for the registries.conf or add overwrite: true to the ignition config.
