add ability to run as non root user

For some reason this does not work for me. Can you specify which host OS you're using and whether the 100 user already exists on the host?

The host OS is Ubuntu 22.04. Both user and group IDs were already taken on my host OS, after the script is run my folders look like below. The uid maps to the user '_apt' and the gid maps to 'systemd-journal', but I don't think this matters in the container. Additionally the folders have a 775 mask.

ll | grep -E 'cache|config|records'
drwxrwxr-x 2 _apt    systemd-journal 4.0K Dec  1 14:37 cache/
drwxrwxr-x 2 _apt    systemd-journal 4.0K Nov 30 14:15 config/
drwxrwxr-x 2 _apt    systemd-journal 4.0K Nov 30 00:15 records/

When I execute this on my system, I get the errors:

dns-prod-1  | 01-Dec-2023 16:40:23.493 the working directory is not writable
dns-prod-1  | 01-Dec-2023 16:40:23.501 loading configuration: permission denied
dns-prod-1  | 01-Dec-2023 16:40:23.501 exiting (due to fatal error)

I don't know why that occurs, doesn't matter if I set the compose folder to rw.

Just updated the shell script to set a 775 mask on the folders. See if that works

Did mask 775 allow the container to access those directories?
