How do I write to a volume container as non-root in docker?

Question

How do I mount a volume writable by a non-root container user? I am ok with either the volume being owned by the non-root user or permissions being set to 777.

Dockerfil

Answer 1

That is not yet supported, and is studied in issue 2259.
That affect other images like docker-java.

Basically, you have to chown and copy (with the right user) your data in the volume, which is not very convenient.
