Stupid Question - Routing subdomains to various services on a single host. - eviltoast

Edit

Damn, Lemmy is so awesome!

Thanks so much everybody for the quick amazing replies! I will look into the suggested reverse proxy options and get something set up.

Thanks again for all of the insight!

End edit

Let’s say I have multiple services and applications running on my server.

In this case, I’m using docker and have layer 2 docker network to give each container a dedicated IP.

Internally, I can navigate to the local IP to utilize or access them.

How would I go about accessing each service through the internet using different subdomains? Right now all subdomains and the primary domain route directly to my external IP and seem to all resolve to the same service /application.

I imagine this would have to be done with some sort of routing rules but would love some insight! I have a UniFi Dream Router.

    Im using traefik as reverse proxy for everything, docker container or not.

    Bonus: If you own a domain name, you can get https certificates without opening http ports to the outside via dns challenges. You can even get certs for wildcard domains like *.example.com

      Do you know of a good reference for using Traefik with non-docker uses? I’ve struggled to figure that one out lol

        What you need is a so called File Provider. The linked blog post seems to summarize this pretty good, at least better than the original docs.

        You define your path as a “router” and the ip traefik should point to as “service”. Optionally, you can define all kinds of “middlewares”. Example:

        # As YAML Configuration File
http:
  routers:
    router1:
      service: myService      <-- Edit: this should be service1, so it uses your defined service below
      middlewares:
        - "foo-add-prefix"
      rule: "Host(`example.com`)"

  middlewares:
    foo-add-prefix:
      addPrefix:
        prefix: "/foo"

  services:
    service1:
      loadBalancer:
        servers:
          - url: "http://127.0.0.1:80"
