Confused about Podman (sh.itjust.works)

Before I dabbled a bit with Docker. I wanted to dabble a bit with Podman because it seemed quite interesting. I reinstalled Pi OS Lite on my Pi 3B+ and installed Podman. Then I figured out what to run and started digging through the documentation. Apparently Docker containers work quite similar and even Docker compose can be used. Then I came across the auto update function and stumbled upon quadlets to use auto update and got confused. Then I tried reading up on Podman rootless and rootful and networking stuff and really got lost.

I want to run the following services:

Heimdall
Adguard Home
Jellyfin
Vaultwarden
Nextcloud

I am not sure a Pi is even powerful enough to run these things but I am even more unsure about how to set things up. Do I use quadlets? Do I run containers? How do I do the networking so I can reach the containers (maybe even outside my home)?

Can someone point me in the right direction? I can't seem to find the needed information.

For those who are out of the loop, why is podman shit? It is rootless and crazy fast.

It isn't. It's architecture changes pretty significantly with each version, which is annoying when you need it to be stable. It's also dominated by Redhat, which is a legit concern since they'll likely start paywalling capabilities eventually.

I have never seen any of those things. Podman is fast and rootless with almost no overhead. It has good compatibility with docker as well.

Also it would make zero sense to paywall podman as Kubernetes exists. Anyway RHEL is payed anyway.

Just cause you've never seen them doesn't make it not true.

Try using quadlet and a .container file on current Debian stable. It doesn't work. Architecture changed, quadlet is now recommended.

Try setting device permissions in the container after updating to Debian testing. Also doesn't work the same way. Architecture changed.

Redhat hasn't ruined it yet, but Ansible should provide a pretty good idea of the potential trajectory.
