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.
Any chance for an official flatpak? The current one on Flathub is outdated and requires lots of permissions because they couldn’t figure out xdg portals.
