Yes. Mostly
There seems to be a way of mounting an image as data image of another
container and then from this other container modifying the original
one.
See "Using the Dockerfile for provisioning" in
http://oliverguenther.de/2015/05/docker-containers-for-development/
but I am not yet sure what exactly happens.
I think Roland Huss may be able to enlighten us a bit on this.

I think you can do all that -- see
https://goldmann.pl/blog/2014/07/23/customizing-the-configuration-of-the-wildfly-docker-image/#_summary

You have probably seen that I mount /opt/hawkular from inside the
container to /tmp/opt/hawkular on the host.
If we would move the config into /opt/hawkular, it would be writable
and even modifiable from outside of the container (of course it would
still need a restart in the current state).
