What is the killer feature that will make me want to switch from Docker Compose to Podman Quadlets?
replies(7):
1. Podman is simpler than Docker. There is no long-running daemon. Rootless is default.
2. Quadlets can be managed as systemd services, giving me the same tools to manage and view logs for system daemons and containers.
Quadlets have been especially nice for bundling up an AI app I wrote as a cloud-init file, making it easy to deploy the hardware, software and models as one artifact.
Making systemd a necessary dependency to run > 1 container kinda negates many of the the nice advantages that podman has of not requiring root.
podman compose doesnt require root and would serve as a substitute but it's a very neglected piece of software.
You can complain that you don't liken systemd's design or that it does too much (very overplayed complaint, but ok).
But that's an orthogonal point to the initial complaint you've made that it's somehow bad that this requires systemd to run.
That complain is moot, since you'd be running systemd anyway, with or without those containers. And it's double moot, because you can run > 1 containers (with podman) without root too.
(It's also wrong that systemd was added container compose capabilities - podman is what translates things to systemd "speak")
It's not at all orthogonal. Making the "default" way to run > 1 containers together require the init process is fucking stupid.
Similar to how requiring ROOT to run containers was a stupid design decision made by docker.
This decision to make quadlets the "default podman orchestrator" and to double down on it relegates podman from being "a better docker" to just "docker just with different design mistakes".
>That complain is moot, since you'd be running systemd anyway
false. systemd is not the only pid 1 in existence (much as it likes to pretend it is). when you run a container inside a container there also isn't a systemd.
>And it's double moot, because you can run > 1 containers (with podman) without root too.
except there is NO good orchestration system for doing that. podman compose is a steaming pile of shit. quadlets requires systemd which requires root. docker compose requires a root service. you can run podman compose inside a container but not quadlets.
might as well just use docker at this rate.
>That complain is moot
Your comment comprehensively missed my point 3 times. It's triple moot. It would have been better left unmade.
