EDIT: For some context, I recently gave podman another go. I have a few services on my homelab server set up in docker containers, so I tried migrating to podman.
After the second major bug (open issue on github) I encountered looked like it would require completely dropping using compose files to work around, I gave up and went back to docker.
I like the idea of podman, but it’s just not stable. I’ll try again in a year or so.
As a bonus, docker’s CLI is significantly nicer.
How does podman handle docker compose tasks?
Through a hacky Python script (podman-compose), but apparently it works. But IMHO there’s no reason not to just rewrite compose files as quadlets. I think it’s so neat that they work pretty much just like normal systemd units, it makes it feel a lot more logical especially if you’re used to pre-container workflows.
One problem with Podman is that there isn’t a lot of newbie-proof documentation, tutorials etc. partially because it’s not as popular as Docker and partially because it’s developed by Red Hat and they want you to get a RHEL license to access learning resources and support. But if you’re good with man pages, this shouldn’t be much of a problem, it’s easy enough to figure out what to do.
I prefer compose for development instead of quadlets. Actually I prefer compose either way although I use quadlets on my server.
With quadlets all projects files are in the same location and you need separate files for each container, volume, network, etc.
They don’t just work pretty much like systemd units; they are generated into systemd units
Couldn’t someone like you type up a short list with tips and tricks and post it where the newbies can find it?
I would recommend using the docker-compose cli pointed at a podman socket over podman-compose. I don’t think anyone has been recommending podman-compose for quite a while now.
Interesting.
I used to do it the way you’re recommending (before I had podman compose), but I got tired of installing docker compose, and haven’t suffered enough for just using Podman compose, lately.
I do think more things are more likely to work the way you’re saying. Compose doesn’t seem to be standardized yet? And the original dev was probably using Docker compose - for any randomly selected project.
But when I can get away with podman compose, I do, as I recall it being much easier to setup.
Probably as good as it can, you shouldn’t use docker compose with podman anyway, there are two alternatives (quadlets - they describe everything as a systemd units and kube yaml - they use standard k8s yaml files including pods, deployments, secrets, etc.), both arguably better than compose.
I’ve always had issue with
podman-compose. So I setup a podman socket and use it with docker compose.Haha. Yes. This meme would be more fair to call “podman compose” out as “we have Docker compose at home”.
I’m not a fan of the compose pattern anyway. So it doesn’t usually bother me.
There’s
podman-composeavailable through your package manager or pypi.That’s one thing - installing and trying out Podman compose takes less time than remembering where to get Docker compose from.
I always at least try it first, because it’s not expensive to try.
Surprisingly well?
It’s rare when I have to look up special instructions for podman. Once þe setup is ironed out commands are mostly interchangeable.
Þe podman team have done a great job.
Can you stop using thorn? It’s quite a problem for some people, it makes reading very hard for them
