Same host different paths on docker containers

Traefik Traefik v3 (latest)

Issue:
Hello, I have a Docker Compose file for frontend1. I want to configure it to handle all paths except those starting with sitemap or rss. However, for the frontend2 container, I only want it to respond to requests directed at the sitemap and rss paths.

Regex Patterns:

(www\.)?(foobar.com\/(?!(sitemap?.+|rss?.+)).+) - Handles all paths except sitemap and rss.
(www\.)?(foobar.com\/((sitemap?.+|rss?.+))) - Handles only sitemap paths.

Question:
I'm looking for advice on how to implement these regex patterns effectively within my Docker Compose configuration. Specifically, how can I ensure that frontend1 handles all paths except sitemap and rss, while frontend2 responds only to requests directed at the sitemap and rss paths?

Docker Compose Configuration:

frontend1:
  image: docker.io/foxsnow/next-frontend:test
  command: >
    sh -c "npm run feb && npm run fen"

  environment:
    - NEXT_PUBLIC_SERVER_URL=$NEXT_PUBLIC_SERVER_URL
    - NEXT_PUBLIC_SITE_URL=$NEXT_PUBLIC_SITE_URL

  networks:
    - supabase
    - bridge

  labels:
    - traefik.enable=true
    - "traefik.http.routers.frontendsite.rule=Host(`foobar.com`) || Host(`www.foobar.com`)"
    - traefik.http.routers.frontendsite.entrypoints=websecure
    - traefik.http.routers.frontendsite.tls=true
    - traefik.http.routers.frontendsite.tls.certresolver=myresolver
    - traefik.http.routers.frontendsite.service=frontendsite
    - traefik.http.services.frontendsite.loadbalancer.server.port=3001
    - traefik.http.routers.frontendsite.middlewares=mywwwredirect
    - traefik.docker.network=supabase

  restart: always

frontend2:
  image: docker.io/foxsnow/next-frontend:test
  command: >
    sh -c "npm run feb && npm run fens"

  environment:
    - NEXT_PUBLIC_SERVER_URL=$NEXT_PUBLIC_SERVER_URL
    - NEXT_PUBLIC_SITE_URL=$NEXT_PUBLIC_SITE_URL

  networks:
    - supabase
    - bridge

  labels:
    - traefik.enable=true
    - traefik.http.services.frontendsite.loadbalancer.server.port=3001
    - traefik.docker.network=supabase

  restart: always

Thanks:
Thank you in advance for any assistance or insights you can provide!

Simple router rule:

.rule=Host(`example.com`) && ( PathPrefix(`/sitemap`) || PathPrefix(`/rss`) )

You only need this for the one matching. The rule is longer, therefore has higher priority, will be matched first.

Hello, @bluepuma77

Like that same router ?

frontend1:

  labels:
    - traefik.enable=true
    - "traefik.http.routers.frontendsite.rule=Host(`foobar.com`) && ( PathPrefix(`/sitemap`) || PathPrefix(`/rss`) )"
    - traefik.http.routers.frontendsite.entrypoints=websecure
    - traefik.http.routers.frontendsite.tls=true

Longer rule for the one for sitemap/rss.

Note hat using sh in command will result in signals not being passed to the script running AFAIK. So if you run multiple instances and want a rolling update with graceful shutdown, this won’t work.

You need separate services with separate router names. Sitemap gets the longer rule as you had it in the compose file.

You can centralize http-to-https redirect and TLS on entrypoints, see simple Traedik example.

This example its not showing what I want.
Can you edit my compose file and show me what you realy want to show Sir ?

Hello @bluepuma77,
When I made like that sir
- "traefik.http.routers.testsite.rule=Host(test.foobar.com) && !Path(/{sitemapath:(sitemap?.+|rss?.+)})"
I still can go to test.foobar.com/sitemap.xml
how is still happen ?
Thank you Sir.

I explained how it should be done.

Why do you use Path and think you can place a Regex inside? Please read the v3 docs.

Documentation style needs to change. When I look in google path regex it not seem Sir.
