Set environment variable:

: The container user (www-data) cannot write to the mounted host directory.

: A web file manager is a double-edged sword. It provides incredible convenience, but if misconfigured or left unsecured, it can expose your entire server. Always follow the principle of least privilege—only mount the directories you absolutely need, always use HTTPS, and monitor access logs.
