 Mattermost Omnibus packages the free, unlicensed Mattermost Enterprise version of Mattermost, a PostgreSQL database, and when required, NGINX as the application proxy. A custom CLI (``mmomni``) and ansible recipes link the components together and configures them. Mattermost Omnibus is only supported on Ubuntu distributions.
