podman-compose VS mariadb-podman-socket-activation

Podman (via podman-compose),

Source code for the feature is here if you care to inspect it:

https://github.com/containers/podman-compose/blob/bce40c2db3...

Admittedly, I'm still on podman 4.3.1, but I dont' see any reason why this would stop working in later versions of podman.

Can someone link me to what Compose means in this context? Google takes me to https://github.com/containers/podman-compose but I just wanna make sure that's what they are talking about.

🛑 Docker Desktop is free for personal use but requires a paid subscription for enterprises. A free open source alternative is Podman and Podman Compose which uses the same core syntax as the Docker tools and can be used as a near drop-in replacement.

I’m dumb. When I wrote the article it was late. Docker-Compose really was a game changer.

Yea Podman compose exists. I’ll add a section about docker compose to it in an update.

From googling this error I've come across a few different threads but I haven't gained any success. Firstly I found this github thread which doesn't reference my error but still seems related. I followed the "sudo podman-compose systemd --action create-unit" and "podman-compose systemd -a register -f myfile.yml" minus the -f flag as it wouldnt run with that. This indeed created a [email protected] file, but its created in the /etc/systemd/user directory rather than /etc/systemd/system which raises an issue as I'm having to run these two containers as root. I try registering the podman-compose@torrent but I'm told the service doesnt exist. Running it as user I'm told it failed to connect to bus: no medium found. So I basically reached a dead end there.

Have a look at Podman Compose

You can also use podman-compose for the orchestration https://github.com/containers/podman-compose

In addition to that Podman supports socket activation that passes the socket to the container. Interestingly, this opens up the possibility to run a network server (e.g. a web server) with --network=none (i.e.podman run --network=none ...) in case the server process is happy with only communicating over the TCP socket it was passed. This increases security. Some references: https://github.com/containers/podman/discussions/13390 https://github.com/eriksjolund/mariadb-podman-socket-activation

Support for socket activation

Podman will pass on the socket-activated socket to the container.

I wrote a small example demo for setting up socket activation with systemd, Podman, and a MariaDB container:
