It's not working as expected yet. I am adding the following as environment variable:
APACHE_RUN_USER: #1021
And the error is:
chown: invalid spec: '1021':

@quartje - there was an error in my logic when chowing. Fixed in the last commit. Can you please pull, rebuild and try again?

It works. However, restarting a container fails:

AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 172.17.0.3. Set the 'ServerName' directive globally to suppress this message

@quartje - added a fix to take care of this, only add the user if it does not exist. Please pull and retest.

It works!
Lets merge :)
