Description Standa Laznicka 2019-05-09 11:12:02 UTC

Description of problem:
In 4.1, the commands `oc adm policy add/remove-scc-*` are broken if applied on an SCC from the default SCC set - they have a very short-lived effect since the platform-provided SCCs are handled by the cluster version operator (CVO).

The aforementioned commands work by changing the Users/Groups fields of a specific SCC. If the SCC is one of the platform-provided, CVO will eventually stomp on the change and will revert it to platform-default

Version-Release number of selected component (if applicable):
4.1

How reproducible:
100%

Steps to Reproduce:
1. oc adm policy add-scc-to-user privileged milan
2. wait a bit

Actual results:
User "milan" won't eventually be able to set up pods that would require the "privileged" SCC .

Expected results:
User "milan" can create privileged pods unless removed from the "privileged" SCC by some other user.

Additional info:

WORKAROUND:
===========
It is possible to create a cluster role that would allow the user "use" the "privileged" SCC. The process of creating the cluster role and role bindings to it is described in the official documentation: https://docs.openshift.com/container-platform/4.1/authentication/managing-security-context-constraints.html#role-based-access-to-ssc-configuring-internal-oauth

Sally, sync with Standa what needs to be done and let this ship in 4.4.

Comment 5 Sally 2020-02-27 19:00:56 UTC

I've confirmed with latest version `Cluster version is 4.5.0-0.ci-2020-02-27-004716` that this is no longer an issue.  I am able to:
$ oc adm policy add-scc-to-user privileged testuser, then create a privileged pod.  

Also, I confirmed I can:
$ oc adm policy remove-scc-from-user privileged testuser, then am no longer able to create the privileged pod.

Confirmed with latest oc client, the issue has fixed:
