Thanks for the PR @mtunique! I actually ran into this today and have a fix
[in a
branch](https://github.com/patricklucas/flink/tree/FLINK-6330_improve_docker_docs)
that I will hopefully open a PR for tomorrow.
I had exactly your change, but tweaked it slightly to tolerate being called
from sudo.
You could either just wait for me to merge that change, or continue with
this PR, but please implement the change as I did in the branch I linked above.
