Here is a minimal example for **exposing Promehteus with auth**. No swarm, no TLS:

> **docker-compose.yaml**
>
> ```yaml
> version: "3.3"
> 
> services:
> 
> traefik:
> image: "traefik:v2.0.4"
> container_name: "traefik"
> ports:
> - "80:80"
> - "8080:8080"
> volumes:
> - "/var/run/docker.sock:/var/run/docker.sock:ro"
> - "./traefik.toml:/traefik.toml"
> labels:
> - "traefik.enable=true"       
> - "traefik.http.routers.metrics.entrypoints=http"
> - "traefik.http.routers.metrics.rule=Path(`/metrics`)"
> - "traefik.http.routers.metrics.service=metrics"
> - "traefik.http.routers.metrics.middlewares=auth"
> - "traefik.http.middlewares.auth.basicauth.users=test:$$apr1$$H6uskkkW$$IgXLP6ewTrSuBkTrqE8wj/,test2:$$apr1$$d9hr9HBB$$4HxwgUir3HP4EsggP/QNo0"     
> - "traefik.http.services.metrics.loadbalancer.server.port=5443"
> 
> ```

> **traefik.toml**
>
> ```auto
> [entryPoints.http]
> address = ":80"
> [entryPoints.metrics]
> address = ":5443"
> 
> [api]
> insecure = true
> 
> [log]
> level = "debug"
> 
> [accessLog]
> 
> [metrics.prometheus]
> addEntryPointsLabels = true
> addServicesLabels = true
> entryPoint = "metrics"
> 
> [providers.docker]
> exposedByDefault = false
> 
> ```

Here you expose `/metrics` on 5443, then you create a service to point to that port, a router to point to that service, and then you can access it at `http://yourhost/metrics`. You will have provide credentials such as `test:test`.

Hope this helps.
