7 Common Docker Compose Settings, Explained

This video is sponsored by Omen. Omen Sentry continuously monitors coolant health in liquid-cooled data centers, tracking pH, alkalinity, glycol concentration, and more, and feeds that data into your building management system so problems don’t go unnoticed between lab samples.

For the last several years, we've been talking about Docker and pretty much everything around it, but we never really stopped to explain the pieces that show up in almost every compose file. In this video, I take a step back and walk through seven of them using a single Jellyfin compose file: volumes vs bind mounts, PUID and PGID, read-only mounts, network modes, restart policies, resource limits, and privileged vs devices and cap_add.

We start with a bare-bones file and add one piece at a time until we end up with something I'd actually want running on my server.
