Traefik dashboard on another port and with authentication

Here is an example for Traefik dashbord on port 9090 and with basic auth middleware.

To generate password:

echo $(htpasswd -nb user password) | sed -e s/\\$/\\$\\$/g

For services routers it’s important to set entryPoints with correct port: "traefik.http.routers.ui.entryPoints=web".

version: '3.3'
services:
  ui:
    image: "ui:v1.0.0"
    restart: always
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.ui.entryPoints=web"
      - "traefik.http.routers.ui.rule=Host(`${HOST_NAME}`)"
      - "traefik.http.services.ui.loadbalancer.server.port=8080"
      - "traefik.http.services.ui.loadbalancer.server.scheme=http"
  traefik:
    image: "traefik:v2.1.7"
    restart: always
    command:
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.dashboard.address=:8080"
      - "--api=true"
      - "--api.dashboard=true"
      - "--accesslog=true"
    ports:
      - "80:80"
      - "9090:8080"
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.dashboard.entryPoints=dashboard"
      - "traefik.http.routers.dashboard.rule=Host(`${HOST_NAME}`)"
      - "traefik.http.routers.dashboard.service=api@internal"
      - "traefik.http.routers.dashboard.middlewares=dashboard-auth@docker"
      - "traefik.http.middlewares.dashboard-auth.basicauth.users=user:$$apr1$$31lOQwG4$$VD15Ln4o5f5GgixYie9tW0"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
