Description

uid 1337 is hardcoded for sail user in Dockerfiles:

sail/runtimes/8.4/Dockerfile

Line 62 in 20f2fb8

RUN useradd -ms /bin/bash --no-user-group -g $WWWGROUP -u 1337 sail

So $WWWGROUP can be specified but $WWWUSER can not be specified. This is problematic with some configuations of userns_mode.

It gives error when trying to apply the patch in start-container:

if [ ! -z "$WWWUSER" ]; then
    usermod -u $WWWUSER sail
fi

usermod: UID '1000' already exists

Which lefts sail user with uid 1337 and not 1000

Steps To Reproduce

1. Write WWWUSER: 1000 inside docker-compose.override.yml
2. sail build --no-cache
3. usermod -u $WWWUSER sail patch fails in start-container
4. Created user sail has uid 1337
