Running the archivebox manage createsuperuser command interactively is no longer the only way to create a user, you can now also use the environment variables ADMIN_USERNAME + ADMIN_PASSWORD to setup the admin user automatically on first run as of v0.7.2.

We also support LDAP for authentication, or custom headers for authentication (when using a reverse proxy that handles auth) using REVERSE_PROXY_USER_HEADER + REVERSE_PROXY_WHITELIST. I'm not sure how Cloudron handles auth, but maybe these are helpful to ya'll.

Thanks for your efforts packaging ArchiveBox for Cloudron! I've linked to Cloudron from our README as well btw: https://github.com/ArchiveBox/ArchiveBox/tree/dev#-other-options
