It's my homeassistant setup. I run mosquitto, zigbee2mqtt, and homeassistant in it (everything they connect to is on the network, so no need to do USB access mumbo jumbo). I don't "manage" it; I have a yaml file (generated from running containers with "podman kube generate") in a directory along with volumes those containers need, and a file in /etc/containers/systemd pointing to that yaml file. That's it.
And once all peripherals are seen and run correctly, I don't "manage" it as long as it works.
