We've completely transitioned from docker to podman where I work. The only pain point was podman compose being immature compared to docker compose, but turns out you can run docker compose with podman using the podman socket easily.
I gave podman compose a fresh try just the other day and was happy to see that it "just worked".
I'm personally pissed about aardvark-dns, which provides DNS for podman. The version that is still in Debian Stable sets a TTL of 24h on A record responses. This caused my entire service network to be disrupted whenever a pod restarted. The default behavior for similar resolvers is to set a TTL of 0. It's like people who maintain it take it as an opportunity to rewrite existing solutions in Rust and implement all the bugs they can. Sometimes feels like someone just thought it would be a fun summer break project to implement DNS or network security.
I think you wrote it back ways: transitioned from docker to podman?
Yeah podman should use quadlets, not compose, but still works just fine with docker compose and the podman socket!
Oops. Thanks for the correction.
I hadn't heard of quadlets. I'll have to give them a look.
