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!

    That wouldn’t work if multiple containers use the same port (eg. 8000), right?

    Without a docker network, I can just map 8001:8000 and don’t have that issue.

      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.
