Support local reverse proxy urls

[uvulpos]

I gave shannon the internal url to request (it's http://web.nextreleaseplease.com/login, there is a local dns record in /etc/hosts to 127.0.0.1) but the docker container of course does not have access to this url. How can I set a custom dns record, to reroute it to docker.internal for local testing?

services:
  reverse-proxy:
    image: "traefik:v3.6.12"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
    ports:
      - "80:80"
      - "443:443"
      - "8080:8080"
    command:
      - "--api.insecure=true"
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.web-secure.address=:443"
    networks:
      intranet:
        aliases:
          - web.nextreleaseplease.com

  frontend:
    image: node:25.9.0
    container_name: web-ui
    restart: unless-stopped
    ports:
      - 5173:5173
    environment:
      - FRONTEND_ENVIRONMENT_NAME="development"
    volumes:
      - ./services/frontend:/app
    depends_on:
      reverse-proxy:
        condition: service_started
    networks:
      - intranet
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.frontend.rule=(Host(`web.nextreleaseplease.com`)&&PathPrefix(`/`))"
      - "traefik.http.routers.frontend.priority=1"
      - "traefik.http.routers.frontend.service=frontend"
      - "traefik.http.services.frontend.loadbalancer.server.port=5173"
      - "traefik.http.routers.frontend.entrypoints=web,web-secure"
    command: ["sh", "-c", "cd /app && npm install && npm run dev"]

why this approach? Because then I can have everything without cors issues and I can also route depending services like grafana to it
