Traefik 2.0 tcp 路由试用

对于tcp 的路由是基于sni (需要tls)但是可以通过统配(*) 解决不试用tls的,当然也可以让Traefik 自动生成tls 证书
以下是测试http 以及mysql 的tcp 路由配置(demo 很简单,就是一个proxy)

环境准备

  • docker-compose文件
 
version: '3'
services:
  database:
    image: mysql:5.7.16
    labels:
      - "traefik.tcp.routers.mysql.rule=HostSNI(`*`)"
      - "traefik.tcp.routers.mysql.entrypoints=mysql-default"
    command: --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
    environment:
      MYSQL_ROOT_PASSWORD: dalongrong
      MYSQL_DATABASE: gogs
      MYSQL_USER: gogs
      MYSQL_PASSWORD: dalongrong
      TZ: Asia/Shanghai
  database2:
    image: mysql:5.7.16
    labels:
      - "traefik.tcp.routers.mysql2.rule=HostSNI(`*`)"
      - "traefik.tcp.routers.mysql2.entrypoints=mysql-default2"
    command: --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
    environment:
      MYSQL_ROOT_PASSWORD: dalongrong
      MYSQL_DATABASE: app
      MYSQL_USER: app
      MYSQL_PASSWORD: dalongrong
      TZ: Asia/Shanghai
  nginx:
    image: nginx
    labels:
      - "traefik.http.routers.nginx.rule=Host(`dalong.web.localhost`)"
      - "traefik.http.routers.nginx.entrypoints=web"
  reverse-proxy:
    image: traefik:v2.0
    build: ./
    entrypoint: traefik --configfile /traefik.toml
    ports:
      - "80:80"
      - "8090:8080"
      - "3306:3306"
      - "3307:3307"
      - "443:443"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
  • traefik 配置
[global]
  checkNewVersion = false
  sendAnonymousUsage = false
[entryPoints]
  [entryPoints.web]
    address = ":80"
  [entryPoints.mysql-default]
    address = ":3306"   
  [entryPoints.mysql-default2]
    address = ":3307"   
  [entryPoints.web-nginx]
    address = ":443" 
  [entryPoints.traefik]
    address = ":8080" 
[log]
  level = "DEBUG"
[api]
  insecure = true
  dashboard = true
[ping]
[providers.docker]
  endpoint = "unix:///var/run/docker.sock"
  exposedByDefault = true
[metrics]
  [metrics.prometheus]
  • dockerfile
FROM traefik:v2.0
COPY traefik.toml /traefik.toml
  • 说明
    tcp 路由配置需要sni,对于没有tls 证书的我们可以使用* 配置,比如mysql的
 
    labels:
      - "traefik.tcp.routers.mysql2.rule=HostSNI(`*`)"
      - "traefik.tcp.routers.mysql2.entrypoints=mysql-default2"

启动 &&测试

  • 启动
docker-compose  build  
docker-compose up -d
  • 效果

  • http 测试
    配置hosts 文件
    访问效果

 

 

  • tcp 路由测试
    直接使用端口+ ip 方式
    database1
    mysql -uroot -pdalongrong -h127.0.0.1
    效果:

 

 


database2
mysql -uroot -P3307 -pdalongrong -h127.0.0.1

 

 

  • prometheus metrics

 

 

说明

以上是一个简单的测试,主要是 需要sni 支持,但是sni 需要tls,实际我们的连接也需要少有改动,可能四层用haproxy 会更方便点,对于简单,同时数量不多的
四层处理还是挺不错的
