Run xcache as user instead of root#84
Conversation
Even in containers, it's best practice to execute code as a user rather than as root whenever possible. In addition, some multi-tenant Kubernetes systems (Red Hat OpenShift / OKD) have a default security policy that executes containers with an ephemeral UID with GID 0. This change (along with substituting go-crond for crond in the base software image) should enable running as any user with GID 0.

Wouldn't this break multiuser? I will ask around if that's an issue. |

What's this for? Does OKD not like groups?

By default, OKD runs containers with an ephemeral UID and GID 0.

looks like a leftover from testing?

never mind, just saw your line about go-crond.

I don't want to get it working on OKD only to break it on vanilla Kubernetes. I created a new branch, |
