How to expose dashboard to a domain on http

Traefik Traefik v2
1

Here is my trial. It doesn't work. I cannot access the dashboard by http://traefik.local.
Could anyone give me some help? Thanks a lot.

  • docker-compose.yml
version: Compose specification

services:
    traefik:
        image: traefik:2.9
        ports:
            - "80:80"
            - "8080:8080"
        volumes:
            - "./traefik.toml:/etc/traefik/traefik.toml"
            - "/var/run/docker.sock:/var/run/docker.sock:ro"
  • traefik.toml
[log]
level = "INFO"

[api]
dashboard = true
insecure = true

[providers.docker]
exposedByDefault = false

[entryPoints]
[entryPoints.web]
address = ":80"

[http.routers]
[http.routers.dashboard]
rule = "Host(`traefik.local`)"
service = "dashboard@internal"

[http.routers.api]
rule = "Host(`traefik.local`) && PathPrefix(`/api`)"
service = "api@internal"

I don’t think there is dashboard@internal, it’s all api@internal.

Also routers and services need to go into dynamic configuration, which is loaded by a provider like file or docker.

See dashboard routing in the docs:

# Dynamic Configuration
labels:
  - "traefik.http.routers.dashboard.rule=Host(`traefik.example.com`) && (PathPrefix(`/api`) || PathPrefix(`/dashboard`))"
  - "traefik.http.routers.dashboard.service=api@internal"
  - "traefik.http.routers.dashboard.middlewares=auth"
  - "traefik.http.middlewares.auth.basicauth.users=test:$$apr1$$H6uskkkW$$IgXLP6ewTrSuBkTrqE8wj/,test2:$$apr1$$d9hr9HBB$$4HxwgUir3HP4EsggP/QNo0"

See simple example of Traefik docker-compose.yml.

Hi, @bluepuma77
I directly run your simple example of Traefik, I still cannot access http://traefik.example.com
I also tried:

Here is my latest traefik.yml. It still doesn't work.

### Static Configuration
log:
    level: INFO
api:
    insecure: true
entryPoints:
    web:
        address: :80
providers:
    docker:
        exposedByDefault: false
    file:
        # location in traefik container
        filename: /etc/traefik/traefik.yml
---
### Dynamic Configuration
http:
    routers:
        dashboard:
            rule: Host(`traefik.local`) && (PathPrefix(`/api`) || PathPrefix(`/dashboard`))
            service: api@internal
            priority: 1000
            entryPoints:
                - web

api.insecure:true will automatically run Dashboad on :8080.

Use

api:
  # Dashboad
  dashboard: true

And note:

The trailing slash / in /dashboard/ is mandatory

Not work. >_<. I am using the Windows, could this be the cause of the problem?

I had the same problem before, but was finally able to solve it.

First of all, you need to add the network in Docker if you add it externally like I did (it's so you can add other services there as well and Traefik will recognize them).

docker-compose.yml

version: '3'

services:
  reverse-proxy:
    image: traefik
    container_name: "traefik"
    ports:
      - "80:80"
      - "8080:8080"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./traefik:/etc/traefik
    labels:
      - traefik.http.routers.traefik.rule=Host(`traefik.local`)
      - traefik.http.routers.traefik.service=traefik@docker
      - traefik.http.services.traefik.loadbalancer.server.port=8080
#      - traefik.http.routers.traefik.tls.certresolver=lets-encrypt
    networks:
      - proxy
      - default

networks:
  proxy:
    external: true
  default:
    driver: bridge

traefik.yml

providers:
  docker:
    watch: true
    network: proxy
ping:
  manualRouting: true

log:
  filePath: "/etc/traefik/logs/log-file.log"
  level: "ERROR"
accessLog:
  filePath: "/etc/traefik/logs/access.log"

api:
  dashboard: true
  insecure: true

## Static configuration
entryPoints:
  web:
    address: ":80"

Have you set up traefik.local in your hosts file or DSL routers DNS? What happens when you ping traefik.local?

What happens when you access http://traefik.local/dashboard/ ?

Enable Traefik debug log and access log.

Using your case, Still NOT. >.<

I don't config /etc/hosts:

ping: traefik.local: Name or service not known

I hope access traefik dashboard http://127.0.0.1:8080 by http://traefik.local.
If without additional DNS service, Can this be achieved with traefik alone?

TODO:

  • Port Mapping: 8080->80
  • DNS: 127.0.0.1->traefik.local

I found this sample, it can access http://whoami.docker.localhost on the Browser.

version: '3'

services:
    reverse-proxy:
        # The official v2 Traefik docker image
        image: traefik:v2.9
        container_name: reverse_proxy
        # Enables the web UI and tells Traefik to listen to docker
        command: --api.insecure=true --providers.docker
        ports:
            # The HTTP port
            - "80:80"
            # The Web UI (enabled by --api.insecure=true)
            - "8080:8080"
        volumes:
            # So that Traefik can listen to the Docker events
            - /var/run/docker.sock:/var/run/docker.sock
            # ...
    whoami:
        # A container that exposes an API to show its IP address
        image: traefik/whoami
        container_name: reverse_whoami
        labels:
            - "traefik.http.routers.whoami.rule=Host(`whoami.docker.localhost`)"

traefik is not a DNS server. So configuring the /etc/hosts or other DNS server(e.g. adguardhome, dnsmasq) is needed.
Here is my final config:

  • config /etc/hosts 
127.0.0.1 traefik.m.local
  • docker-compose.yml
version: Compose specification

services:
    traefik:
        image: traefik:2.9
        ports:
            - "80:80"
            - "8080:8080"
        volumes:
            # /traefik.yml and /etc/traefik/traefik.yml are both available.
            - "./traefik.yml:/etc/traefik/traefik.yml"
            # dynamic-conf dir is self-defined
            - "./dynamic-conf:/etc/traefik/dynamic-conf"
            - "/var/run/docker.sock:/var/run/docker.sock:ro"
        networks:
            - traefik-net

networks:
    traefik-net:
        name: traefik-net
        ipam:
            config:
                -   subnet: 172.16.238.0/24
