Docker Container/Service with Same Port: Best Practices?
I am very new to using docker. I have been used to using dedicated VM's and hosting the applications within the servers OS.
When hosting multiple applications/services that require the same port, is it best practice to spin up a whole new docker server or how should I go about the conflicts?
Ie. Hosting multiple web applications that utilize 443.
Thank you!

Yes, it'd work just fine because each container listens on port 8000 of their own IP address, not the docker server's IP address. Caddy/Traefik just redirects traffic to that port.
Okay, thanks! Maybe I'll try it in the future.
I've just posted a little example. I'd recommend doing it this way. No more thinking about what port is allready exposed etc
