traefik配置

概述

Entrypoints -> 入口
HTTP Router -> 路由规则
Service -> 可以理解为部署在docker中的容器、这里也可以是在配置文件中自定义的service
TLS -> https

toml配置文件

traefik支持通过toml配置文件手动配置https、自定义Router、Service;

traefik.toml

# 全局配置
[global]
  checkNewVersion = false
  sendAnonymousUsage = false
# 入口
[entryPoints]
  # http 
  [entryPoints.web]
    address = ":80"
  # https "websecure"这个名字是自己定义的  
  [entryPoints.websecure]
    address = ":443"
  #  traefik web ui 
  [entryPoints.traefik]
    address = ":8080" 
# 免费Let's Encrypt 证书（注意：必须域名解析到的主机中才有效，traefik会把秘钥写入acme.json中）
[certificatesResolvers.bxtlschallenge.acme]
  # 自己的邮箱地址
  email = "xxxx@xx.com"
  # 秘钥写入地址，根据自己文件映射来配置
  storage = "/letsencrypt/acme.json"
  [certificatesResolvers.bxtlschallenge.acme.httpChallenge]
  entryPoint = "web"

# 自定义Router、Services（貌似必须定义在外部文件里面，坑了好久）
[providers.file]
  directory = "/etc/traefik/conf"
# traefik 需要开启的功能
[api]
  insecure = true
  dashboard = true
[ping]
[providers.docker]
  endpoint = "unix:///var/run/docker.sock"
  exposedByDefault = true
# 传输配置
[serversTransport]
  # 如果后端需要代理https自定义证书，可以使用这种方式就可以跳过验证，不然会报x509证书错误
  insecureSkipVerify = true

file.toml

[http]
  # 自定义 routers
  [http.routers]
    # http 方式
    [http.routers.routers-cnblogs]
      entryPoints = ["web"]
      rule = "Host(`cnblogs.fanxp.com`)"
      service = "cnblogs"
    # https 方式
    [http.routers.routers-cnblogs1]
      entryPoints = ["websecure"]
      rule = "Host(`cnblogs.fanxp.com`)"
      service = "cnblogs"
      [http.routers.routers-cnblogs1.tls]
        certResolver = "bxtlschallenge"
  # 自定义 services
  [http.services]
    [http.services.cnblogs]
      # 可以设置多个url traefik 根据算法做负载均衡
      [http.services.cnblogs.loadBalancer]
        [[http.services.cnblogs.loadBalancer.servers]]
          url = "https://www.cnblogs.com/fanxp/"
        [[http.services.cnblogs.loadBalancer.servers]]
          url = "https://github.com/fanxiaoping/grpc-test"
