Running occ commands

Starting with 11.0.0-rc1, the image supports running any occ command with full initialization (database, config, etc.) but without starting Apache, by using the occ subcommand in docker-compose.yml:

command: ["/usr/bin/owncloud", "occ", "<occ-command>", "<args...>"]

Example — start the Windows Network Drive SMB listener:

command: ["/usr/bin/owncloud", "occ", "wnd:listen", "myhost", "myshare", "myuser", "--password-file=/run/secrets/wnd_password"]

Environment variables

This image defines no environment variables of its own. Configuration is done through the variables inherited from the base images linked under Inherited environments above.
