```

since we are using path from `/tmp` folder as a mount point, it is causing issue while restarting.

Look for the 'chimney script' that manages the Portainer container, likely in a shell script within the repository. Identify the mount configuration for '/tmp/portainer_password' and understand the directory vs. file mount issue. Check Docker or container runtime documentation for correct volume mount syntax and adjust the script accordingly. Test the change by running the script to ensure the container restarts without the error.
