docker-compose - Traefik v2.1.4 - 如何创建静态路由并重定向到特定主机和端口

Question

我是 Traefik v2.1.4 的初学者。我在 docker 容器中使用。我正在尝试设置静态路由。我找到了一些使用 toml 配置文件的示例。

[providers]
[providers.file]
[http]
    [http.routers]
        [http.routers.netdata]
            rule = "Host(`netdata.my-domain.com`)"
            service = "netdata"
            entrypoint=["http"]

    [http.services]
          [http.services.netdata.loadbalancer]
            [[http.services.netdata.loadbalancer.servers]]
              url = "https://192.168.0.2:19999"

按照这个例子，我想将它转换为我的 docker-compose 的 docker 标签。

我的 docker-compose 文件:

version: "3.7"
services:

  traefik:
    image: traefik:v2.1.4
    container_name: traefik
    restart: always
    command:
      - "--log.level=DEBUG"
      - "--api.insecure=false"
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.websecure.address=:443"
      - "--certificatesresolvers.letsresolver.acme.tlschallenge=true"
      - "--certificatesresolvers.letsresolver.acme.email=my-email@domain.com"
      - "--certificatesresolvers.letsresolver.acme.storage=/letsencrypt/acme.json"
    labels:
      - "traefik.enable=true"
      # middleware redirect
      - "traefik.http.middlewares.redirect-to-https.redirectscheme.scheme=https"
      # global redirect to https
      - "traefik.http.routers.redirs.rule=hostregexp(`{host:.+}`)"
      - "traefik.http.routers.redirs.entrypoints=web"
      - "traefik.http.routers.redirs.middlewares=redirect-to-https" 
      # dashboard
      - "traefik.http.routers.traefik.rule=Host(`traefik.my-domain.com`)"
      - "traefik.http.routers.traefik.service=api@internal"
      - "traefik.http.routers.traefik.middlewares=admin"
      - "traefik.http.routers.traefik.tls.certresolver=letsresolver"
      - "traefik.http.routers.traefik.entrypoints=websecure"
      - "traefik.http.middlewares.admin.basicauth.users=user:hash-passwordXXX"

    ports:
      - "80:80"
      - "443:443"
      - "8080:8080"
    volumes:
      - "./letsencrypt:/letsencrypt"
      - "/var/run/docker.sock:/var/run/docker.sock:ro"


 networks:
    default:
        external:
            name: network

可以到 一起使用 2 个提供程序:file和 docker .
您的 docker-compose.yml :

services:  traefik:    image: traefik:2.2.1    command: traefik --configFile=/etc/traefik/traefik.yml    ports:      - "80:80"      - "8080:8080"    volumes:      - ./traefik.yml:/etc/traefik/traefik.yml      - ./routes.yml:/etc/traefik/routes.yml      - /var/run/docker.sock:/var/run/docker.sock   # your services go here ...

Your traefik.yml:

api:
  dashboard: true
  insecure: true

entryPoints:
  web:
    address: :80

providers:
  docker: {}

  file:
    filename: /etc/traefik/routes.yml
    watch: true

您的 routes.yml :

http:
  routers:
    hello:
      rule: PathPrefix(`/hello`)
      service: hello@docker
      rule: PathPrefix(`/world`)"
      service: world@docker

这些只是示例，当然不要直接在生产环境中使用它们。
