如何将traefik配置为单个域和多个路径的反向代理

问题描述 投票：4回答：1

我正在配置Traefik作为我的开发环境中的反向代理。我目前在不同的端口和不同的PATH上运行应用程序。

我的环境：

Traefik正在运行主机（192.168.0.10）。在端口80,443和8080（traefik仪表板）上收听。

我的应用程序在不同的主机上运行（192.168.0.11）。

Web应用程序：192.168.0.11:8200/web1后端：192.168.0.11：8210 / api1其他Web应用程序：192.168.0.11：8300 / web2其他后端：192.168.0.11：8310 / api2

我想通过Traefik + LetsEncrypt（acme）将所有这些应用程序重定向到同一个子域（dev.domain.com）。

例如：

当我访问dev.domain.com/web1时，我想将所有访问权重定向到192.168.0.11:8200/web1

当我访问dev.domain.com/api1时，我想将所有访问权重定向到192.168.0.11:8210/api1

等等..

以下是我正在使用的设置，Traefik版本等。

traefil.toml

debug = true
logLevel = "DEBUG"
InsecureSkipVerify = false
defaultEntryPoints = ["https", "http"]

[api]
  entryPoint = "traefik"
  dashboard = true
  address = ":8080"

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

[file]
  directory = "/etc/traefik/rules.d"
  watch = true

[acme]
email = "[email protected]"
storage="/etc/traefik/acme/acme.json"
entryPoint = "https"
acmeLogging=true 
onDemand = true
[acme.dnsChallenge]
  provider = "godaddy"
  delayBeforeCheck = 0
[[acme.domains]]
   main = "domain.com"
[[acme.domains]]
   main = "*.domain.com"

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

rules.d目录有多个.toml文件。

web1.toml

    SSLRedirect = true
  [frontends.api-frontend.routes.frontend_api-frontend1]
    rule = "Host:dev.domain.com;PathPrefixStrip:/api1"

acme目录已开启！证书创建没有错误！

泊坞窗，compose.yml

version: "2.1"

services:
  traefik:
    hostname: traefik
    image: traefik:latest
    container_name: traefik
    restart: always
    domainname: ${DOMAINNAME}
    networks:
      - default
      - traefik_proxy
    ports:
      - "80:80"
      - "443:443"
      - "8080:8080"
    environment:
      - GODADDY_API_KEY=${GODADDY_API_KEY}
      - GODADDY_API_SECRET=${GODADDY_API_SECRET}
    labels:
      - "traefik.enable=true"
      - "traefik.backend=traefik"
      - "traefik.frontend.rule=Host:traefik.${DOMAINNAME}"  
      - "traefik.port=8080"
      - "traefik.docker.network=traefik_proxy"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /opt/traefik:/etc/traefik
      - /opt/traefik/shared:/shared

  helloworld:
    image: matheuscarino/simple-nodejs-app:latest
    container_name: helloworld
    restart: always
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      - FOO=BAR
    networks:
      - traefik_proxy
    labels:
      - "traefik.enable=true"
      - "traefik.backend=helloworld"
      - "traefik.frontend.rule=Host:helloworld.${DOMAINNAME}"  
      - "traefik.port=3000"

networks:
  traefik_proxy:
    external:
      name: traefik_proxy
  default:
    driver: bridge

当我需要通过Docker（通过标签）将请求重定向到主机上运行的应用程序时，Traefik工作正常。我的helloworld.domain.com应用程序有效！

当我仅重定向一个应用程序时，Traefik工作正常。从我在同一个子域中配置第二个应用程序的那一刻起，traefik就会在重定向中通过PATH丢失。

我在互联网上搜索了像我这样的用例，但我没有找到人们使用Traefik将应用程序重定向到Docker Engine，Kubernetes等之外。

您需要在前端“AddPrefix：/ myprefix”中添加此参数，并删除后端URL中的路径，如下所示：（url =“http://192.168.0.11:8200/myprefix”）to（url =“http：// 192.168.0.11:8200）

如果您的URL中有PATH，则只需将此“路径”移动到前端配置中的“AddPrefix”参数即可。

所有其他配置都OK！
