Question

首先，如果我没有使用正确的条款来提出这个问题，我很抱歉，但我还没达到这个术语。

我在docker容器中运行traefik并使用PathPrefix选项提供某些服务，例如，www.myserver.com / wordpress重定向到运行wordpress的docker容器。

但是如何让它重定向到Docker容器外？具体来说，我如何让www.myserver.com重定向到我的机器中的端口8080以提供我在主机操作系统中运行的服务（而不是在docker容器中）？

这是我的traefik.toml：

logLevel = "DEBUG"
defaultEntryPoints = ["http", "https"]

[entryPoints]
    [entryPoints.http]
        address = ":80"
        compress = false
        [entryPoints.http.redirect]
            entryPoint = "https"
    [entryPoints.https]
        address = ":443"
        [entryPoints.https.tls]

[acme]
email = "mymail@mail.com"
storage = "acme.json"
entryPoint = "https"
onHostRule = true
#onDemand = true
[[acme.domains]]
    main = "www.myserver.com"

[web]
address = ":8888"

[docker]
endpoint = "unix:///var/run/docker.sock"
domain = "www.myserver.com"
watch = true
exposedbydefault = false

我的docker-compose.yml用于traefik容器：

version: "2"

services:
  traefik:
    image: traefik
    network_mode: "host"
    ports:
      - "80:80"
      - "443:443"
      - "8888:8888"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ${SERVER_DIR}/AppData/traefik:/etc/traefik/
      - ${PWD}/acme.json:/acme.json
      - ${PWD}/traefik.toml:/etc/traefik/traefik.toml
      - ${PWD}/servers.toml:/etc/traefik/servers.toml
    restart: never

Answer 1

我已经摆弄并找到了答案。

在traefik.toml添加：

################################################################
# File configuration backend
################################################################
# Enable file configuration backend
# Optional
[file]
        filename = "servers.toml"

# Enable watch file changes
        watch = true

在docker-compose.yml中将volumes:更改为：

volumes:
  - /var/run/docker.sock:/var/run/docker.sock
  - ${SERVER_DIR}/AppData/traefik:/etc/traefik/
  - ${PWD}/acme.json:/acme.json
  - ${PWD}/traefik.toml:/etc/traefik/traefik.toml
  - ${PWD}/servers.toml:/servers.toml

添加文件servers.toml：

loglevel = "ERROR"

[backends]
[backends.nasweb]
        [backends.nasweb.servers.nasweb]
            url = "http://192.168.1.11:8080"

[frontends]
        [frontends.domain]
                backend = "nasweb"
        [frontends.domain.routes.domain]
                rule = "Host:www.myserver.com"

Answer 2

使用新的Traefik（v.2），您需要结合使用标签和外部文件，您可以在下面的工作示例中找到

。

在docker compose中，您需要添加命令以定义外部文件并启用提供程序

  - "--providers.file=true"
  - "--providers.file.filename=/etc/traefik/rules.toml"

进入文件（rules.toml）并路由到外部服务（请注意语法，请使用char定义主机（`））

示例：

Docker-compose：

  traefik:
    image: "traefik:v2.0.0"
    container_name: "traefik"
    restart: always
    command:
      - "--api.insecure=true"
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.websecure.address=:443"
      - "--certificatesresolvers.myhttpchallenge.acme.httpchallenge=true"
      - "--certificatesresolvers.myhttpchallenge.acme.httpchallenge.entrypoint=web"
      - "--certificatesresolvers.myhttpchallenge.acme.email=xx@xx.com"
      - "--providers.file=true"
      - "--providers.file.filename=/etc/traefik/rules.toml"
      - "--providers.docker=true"
      - "--providers.file.watch=true"
    ports:
      - "80:80"
      - "8080:8080"
      - "443:443"
    networks:
      - proxy
    environment:
      - CF_API_EMAIL="xx"
      - CF_API_KEY="xx"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
      - "./traefik/rules.toml:/etc/traefik/rules.toml"

Rules.toml

  [http.routers]
   # Define a connection between requests and services
     [http.routers.nasweb]
        rule = "Host(`nas.xxxx.com`)"
        entrypoints = ["websecure"]
        service = "nas"
     [http.routers.nasweb.tls]
        certResolver = "myhttpchallenge"


 [http.services]
        # Define how to reach an existing service on our infrastructure
        [http.services.nas.loadBalancer]
           [[http.services.nas.loadBalancer.servers]]
             url = "http://192.168.0.165:80"
