OpenShift compatibility #1

Open rarkins opened 3 years ago

rarkins commented 3 years ago

I think our images have previously aimed at v3 OpenShift compatibility but may not be v4 compatible. In particular we set USER 1000 but may rely on hardcoded /home/x. For some of our tools we rely on them finding config in their home directory.

I found a discussion prior to v4 which gives some hope that we might still be able to put them in /home/x and it works despite random UIDs: https://github.com/openshift/origin/issues/23369#issuecomment-511387505

If as that comment indicates we can set HOME=/home/x and ensure it's writable by group 0 then it could be enough for tools to find their "home directory config" regardless of what UID they run as.

Another question remains though: is it forbidden to set USER 1000 in our images for OpenShift compatibility as seemed to be recommended in OpenShift v3, or we just need to be aware of its limitations.
