Running Podman in production for years now, and I don't miss the Docker daemon one bit.

I just published a deep dive on managing OCI containers the Unix way: daemonless, rootless, and natively integrated with systemd via Quadlets.

I cover:
- Real secrets management
- Auto-updates via systemd timers
- The Docker compatibility layer

This is the guide I wish I had when making the switch.

Podman in Production: Quadlets, Secrets, Auto-Updates, and Docker Compatibility

An opinionated production-ops guide to Podman on Linux servers - why I prefer it over Docker, how Quadlets replace Compose files, and practical patterns from real deployments including secrets mana...

@Larvitz nice!

I am halfway with podman; still have compose files launched from systemd units that I write myself - they are all basically identical except the home directory setting 🙂

I deliberately use compose start only, not run. I do not want restarts to be messing about pulling new images when I dont expect it!

Is there an equivalent to quadlets for alternative init tools? I would not want to lock myself into systemd right now 😁 seriousky looking at BSD.

@Slash909uk I doin't know of any alternatives. Quadlets are transniently transformed into systemd units by a generator. That's all very systemd specific.

FreeBSD's Podman port ships with rc.d service scripts already. You enable them with:

sysrc podman_enable=YES
service podman start
sysrc podman_service_enable=YES
service podman_service start

Then, containers started with --restart=always will be automatically restarted after a host reboot. Podman's internal restart logic handles this, with the podman service acting as the supervisor. This is the closest equivalent to what quadlets do on Linux.

@Larvitz thanks, good to know there is BSD support already 👍
