We have had to replace RHEL systems with Ubuntu to keep some of our applications running as they fail on Podman. A major problem is also that podman-compose is far from feature parity with docker-compose.

I replaced Centos8 with Amazon Linux 2 ("amazon linux extras" provides a working docker installation) for exactly the same reason. I like the idea of podman and buildah and I wish them well, but for the time being I can't afford to debug the missing pieces and subtle failures.

I use Docker Swarm (technically "Swarm Mode") in production, and I'm really happy with it - it's so easy to configure and operate, but I am worried that it will no longer be maintained at some point.

If for no other reason that, they don't do Windows containers :) I know of quite a few corps using Windows containers in prod. now, take up may have been slow, but it's happening.

Also Docker for Windows/Mac have an easier install/setup process than manually setting up VMs and installing tools on them.

Maybe not, but considering how much they gave, I think we should want them to live on, and do what we can to help them. Do we really want to live in a world where a startup company makes as big an impact on the way we develop and deploy software as Docker did, only to have all possible business taken from it by bigger players?

There have been lots of great technologies that haven’t directly made their creators rich, but their good legacy usually/eventually catches up with them.

I think that's the just-world fallacy. [1] It's up to us to reward good work. So I guess I should go get a paid Docker Hub account.

I don't think the poster you're replying to was invoking a just world fallacy, however. I read it as saying that developers who build solid systems that people like tend to thrive, even if their business fails.

That appears to be true, and not because of karma, because top-tier developers are in very high demand. Demonstrating that you're one of those isn't the same thing as running a successful business.

Yes, you read it correctly, running privileged docker-in-docker containers with podman to spawn docker containers in dind containers. The good thing is that networking was handled flawlessly. And there were no conflicts between docker and podman

Moby is docker effectively. Your link describes how to install docker on Fedora.
