Improve documentation #3
Description
Dockerhub documentation is slim and does not result in a working container.
Recent versions fail due to missing XML config as described in #1.
Older versions fail due to access privilege issues unless -u root is passed in docker run command, but this is not documented anywhere. Documentation should indicate what user privileges are required to run the container and which user(s) can be expected to have those privileges.
From 6.4.3 without -u root:
(13)Permission denied: AH00091: apache2: could not open error log file /var/log/apache2/error.log.
AH00015: Unable to open logs
Action '-D FOREGROUND' failed.
