Container fails to start with file mounting errors.

Container fails to start with “not a directory” errors. Files being mounted as directories instead of files. Configuration files not being read correctly.

Source files are directories instead of regular files when mounting in Docker.

Steps:

1. Check file type: `ls -la ~/server/irc/`
2. Remove incorrectly created directories: `sudo rm -rf ~/server/irc/config.yml` (if it's a directory)
3. Copy correct file: `cp correct/path/config.yml ~/server/irc/config.yml`
4. Verify file is regular file: `file ~/server/irc/config.yml`
5. Restart container: `docker compose up -d service-name`

Always verify file types before mounting. Use `file` command to check if a path is a file or directory.
