Redirect 如何让traefik从docker内部重定向到特定的非docker端口

首先，如果我没有使用正确的术语来问这个问题，我很抱歉，但我不符合现有的术语

我让traefik在docker容器中运行，并使用PathPrefix选项提供一些服务，例如，www.myserver.com/wordpress重定向到运行wordpress的docker容器

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

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

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"

traefik容器的my

docker compose.yml

：

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

我已经找到了答案

在

traefik.toml

中添加：

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

# Enable watch file changes
        watch = true

在

docker compose.yml中

将

卷：

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 = "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

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"

对于新的Traefik（v.2），您需要结合使用标签和外部文件，您可以在下面找到我的工作示例

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

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

在您的文件（rules.toml）中，输入到外部服务的路由（注意语法，使用char定义主机（`））

例如：

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"

规则.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"
