Unknown command or add-on

Bug Report

I'm running Docker on:

• Windows 11 as a Docker host
• git with core.autocrlf = true (checkout Windows style)

I'm not sure if it's global problem or only mine.

Actual behavior

After building the Dockerfile and running the container, I encountered a problem. The container starts with the error:

Unknown command or add-on! not recognized For help, use /usr/bin/supervisord -h

This was because the Ubuntu shell has a problem with Windows-style line endings in scripts.

Expected behavior

Running without any error

Fix 1:

• force checkout with unix-style line endings even on Windows by using .gitattributes

Fix 2:

• change line ending style after coping startup.sh from host to docker image

I will create PR with Fix 1 for a moment.
