I have nearly the exact question as this solved thread, except with an additional wrinkle.
How to fix docker: Got permission denied issue
I am attempting to use docker commands without sudo, on RHEL 7. However, I am in an enterprise setting, where group memberships are managed centrally. If I add any user to the docker group, they will be removed overnight. And since the privileges of the docker group are basically the same as root, the administrators will not permit any users to retain the docker group.
I can request temporary elevated rights, to sudo as root. What can I do, other than adding users to the docker group, that will allow me to continue to use docker when my temporary rights expire?
