Just like the other commentor said, there are also another container management sowftare called komodo that you can also make it to notify you of new updates

I host my public game server “ports” over a vps, you can just simply rent a cheap/fast vps that is close to your home and configure wireguard to expose the game server ports, Amp cubecode will launch a similar thing to expose on a vps, if you dont mind paying i really recommend that
