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.


Docker is foss. Docker desktop and docker sbx are not.
Are you sure about that? I see Copyright at the bottom (maybe the name) and is free only for personal tier, everything else costs money. Maybe some of the containers are open source per https://www.docker.com/products/trusted-content/open-source/ but I don’t see where it says anywhere that the actual software that is docker is OSS let alone FOSS.
The core of Docker is called Moby, which is open source on GitHub. So are docker-cli and compose
Ah, explains the whale!
It’s FOSS, but not Libre, and more close to open-core than to open source.
It can’t be FOSS but not Libre, the Free in FOSS means Libre. And it also can’t be FOSS but not opensource, of course.
No, Free means “Gratis”, or “Free as in Free Beer”, Libre means “Free as in Freedom”. That’s why FLOSS is recommended to be used instead FOSS, because the latter can be prone to confusion.
The version that is installable from the repositories of Linux distros is all open source. Docker itself, the container engine and runtime are all open source. Nobody cares about stuff like docker desktop or docker sbx, not only are they not critical to the software itself, they aren’t that useful or valuable.
I don’t mean Docker Desktop, I mean docker-cli and moby.
Just because something has a FOSS license and is open-sourced in some code forge doesn’t mean that it effectively respects some (or even all) of the four freedoms.
It’s licensed Apache 2.0, which has been acknowledged as FOSS by the EFF.
Yeah, but I can use the license on my software but not respect that license at all… That’s what I mean. A license itself is nothing if the actions of the developer aren’t corresponding to it.
The version you get from Debian does respect all four freedoms.
