interesting! So I should be able to throw my docker-compose yamls directly at Podman and be good to go?

just curious; why would you like to use podman over docker? I have a lot of docker containers running, wondering if I should switch to podman.

If you are just looking for a way to SSH into your machines from outside your network, you can setup a more recent VPN or Wireguard yourself. If you have a Raspberry Pi lying around, using PIVPN makes things super easy. You can have both OpenVPN as well as Wireguard running if you want, using the same script. If that is the only thing you like to do, then there is no need to reverse proxy your servers and expose them. Just having a VPN or Wireguard connection should be enough to access your servers when outside of your network. It is recommended to have a fixed IP btw, to find your VPN/Wireguard server easily.

Also, you can leave all your servers locally (and not exposing them) when you can reliably setup a VPN/Wireguard connection. That is the most secure I guess.

This also looks similar to Tailscale (https://tailscale.com/). I have not used this but saw it popping up in youtube recently.

Hosting an email server is pretty sure a magnet for half the Chinese IP range… So I would refrain from hosting that myself.

Not sure if it answers your question, but I use Portainer to check the different docker containers I am running. It does not allow me to check the ‘docker-runtime’ logs themselves though, only the logfiles of each of the running containers. It also allows easy term connection if you want, although I usually do that directly form the terminal itself.
