Another tip, please be very careful when exposing ports to the public. With docker you’re already mitigating your attack surfaces but an open port allows anyone to make a connection and there are lots of bots out there looking for open ports and vulnerabilities. A good alternative would be to setup wireguard and instead then connect through that or if you like simplicity check out Tailscale.
Unencrypted HTTP can mean that anyone can see your traffic as it passes through their network. Your ISP will see that traffic. If you’re streaming pirated music and you’re in a country that cares about those things, might not go very well. From a security stand point though, you still wouldn’t want to trust the authentication on the open port. A vulnerability may exist that you don’t know about. It’s always better to keep them closed and add another layer or two between your home computer and the public.
Tailscale let’s you tunnel into your home network without opening any ports, and it encrypts the traffic. Much safer way of doing it.
