Traefik with docker

Traefik不仅仅能作为 ingress 实现 运行在 kubernetes 上，同时也可以直接在 docker上使用

创建网络

docker network create proxy

traefik.yml

api:
  dashboard: true

entryPoints:
  web:
    address: :80
  websecure:
    address: :443

pilot:
  dashboard: false

providers:
  docker:
    endpoint: "unix:///var/run/docker.sock"
    exposedByDefault: false

docker-compose.yml

version: '3.7'

services:
  traefik:
    image: traefik:v2.4
    container_name: traefik
    restart: always
    security_opt:
      - no-new-privileges:true
    ports:
      - 80:80
      - 443:443
    volumes:
      - ./traefik.yml:/traefik.yml:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro
    networks:
      - proxy
    labels:
      - "traefik.enable=true"
      - "traefik.docker.network=proxy"
      - "traefik.http.routers.traefik-secure.entrypoints=web"
      - "traefik.http.routers.traefik-secure.rule=Host(`traefik.lizhe.com`)"
      #- "traefik.http.routers.traefik-secure.middlewares=user-auth@file"
      - "traefik.http.routers.traefik-secure.service=api@internal"

networks:
  proxy:
    external: true

设置好 dns，就可以通过设置的 domain 访问了

然后我们来给它添加一个 nginx

docker-compose.yml

version: '3.7'

services:
  nginx:
    image: nginx
    container_name: nginx
    restart: always
    networks:
      - proxy
      - default
    restart: always
    labels:
      - "traefik.enable=true"
      - "traefik.docker.network=proxy"
      - "traefik.http.routers.nginx-web.entrypoints=web"
      - "traefik.http.routers.nginx-web.rule=Host(`nginx.lizhe.com`)"
      - "traefik.http.routers.nginx-web.service=nginx-web"
      - "traefik.http.services.nginx-web.loadbalancer.server.port=80"

networks:
  proxy:
    external: true

up 之后就多出了一个 nginx
