entrypoint.sh www-data UID/GID issue?

[Mist-Hunter]

Fresh install, docker-compose (yaml below). In the 'web' container, I never see: "The user ${APACHE_RUN_USER} does not exist, creating..." from entrypoint.sh and get the following inside the container:

root@3221c76738f7:/var/www/html# id -u www-data
33
root@3221c76738f7:/var/www/html# id -g www-data
33
root@3221c76738f7:/var/www/html# echo $APACHE_RUN_USER_ID
1000
root@3221c76738f7:/var/www/html# echo $APACHE_RUN_GROUP_ID
1000
root@3221c76738f7:/var/www/html# apachectl -t -D DUMP_RUN_CFG
AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 172.18.0.3. Set the 'ServerName' directive globally to suppress this message
ServerRoot: "/etc/apache2"
Main DocumentRoot: "/var/www/html"

Define: DUMP_RUN_CFG
User: name="www-data" id=33
Group: name="www-data" id=33

I might easily just be confused, and all this expected. But the entrypoint.sh seems to indicate that id -u www-data should equal $APACHE_RUN_USER_ID.

Is it possible that the default apache user is created earlier in the dockerfile and that the following are needed?:

usermod -u $APACHE_RUN_USER_ID www-data
groupmod -g $APACHE_RUN_GROUP_ID www-data

Sorry if I'm way off track here. Thanks for the software. For my needs, I can't find anything else like it. This is probably unrelated, but I'm having issues with random images not loading until I hit the refresh button. Said images are accessed via a CIFs share mounted in the Docker host. I know this is not normal and maybe not supported, but I was double checking permissions when finding all this (which may be nothing).
