I have always been somewhat skeptical of Docker, for example due to how horribly it has always worked on Windows. My first real exposure to containers was when getting into Red Hat certifications and being introduced to Podman, and with the benefit of hindsight I don't really understand the benefit of Docker today when comparing the two. Podman seems just as easy, more restricted and more in line with what some might call "Unix philosophy".
Of course when it comes to distributed environments I'm sure Kubernetes still reigns supreme, but for relatively simple container setups I don't think there's a need to even run Docker anymore on Linux.
Obviously, I'm still not well versed in containers so this might all be overlooking something.
Docker has with no doubt much better UX. It just works and it’s very easy to use. For podman is seems you need a bit more knowing what you are doing. You need to know iptables. With Docker your database container is reachable in the Internet automatically. Not possible to lock it down with iptables rules. (Could be a disadvantage too.)
