Description Adam Mariš 2016-02-10 12:30:23 UTC

It was reported that during docker-build, if 'USER root' is set and 'USER default' is not appended afterward in the Dockerfile, a user gets root in the running pod after deployment.

Spoke with Brenton to confirm this is NOTABUG, misunderstanding of how Docker/builds works.

Comment 2 Jeremy Choi 2016-02-10 23:37:48 UTC

I don't think this can be closed as 'NOTABUG'. At least Openshift Enterprise is preventing this issue, ending up having a non-root user instead. Any reason why Origin cannot do the same thing as Enterprise?
