add an entrypoint.sh script ot inject user/group id dynamically in Docker instance

Issue

I had problem running docker based Aider with different various error, as a last remedy rewrite userid to my differnet non 1000 one.
RUN useradd -m -u XXXXX -s /bin/bash appuser

As a longterm solution would be to add an entry script which would update appuser ids at runtime , smtnhg like this:

#!/bin/bash
set -e

USER_NAME="appuser"
DEFAULT_UID=1000
DEFAULT_GID=1000

# Update appuser's UID and GID if APP_UID and APP_GID are provided
if [ -n "$APP_UID" ] && [ -n "$APP_GID" ]; then
    echo "Updating $USER_NAME UID/GID to: $APP_UID:$APP_GID"

    # Update group ID
    groupmod -g "$APP_GID" "$USER_NAME"

    # Update user ID
    usermod -u "$APP_UID" -g "$APP_GID" "$USER_NAME"

    # Update ownership of relevant directories
    chown -R $APP_UID:$APP_GID /home/$USER_NAME /app /venv
fi

# Execute the container's command
exec "$@"

Update Dockerfile:

# Copy the entrypoint script and make it executable
COPY entrypoint.sh /entrypoint.sh
RUN chmod +x /entrypoint.sh

# In the final image stage, set the entrypoint script while keeping appuser as default
USER appuser
ENTRYPOINT ["/entrypoint.sh", "/venv/bin/aider"]

run the image:

docker run -e APP_UID=$(id -u) -e APP_GID=$(id -g) myimage
