Traefik 与 Consul Catalog¶

启用 consul catalog 提供者

providers:
  consulCatalog: {}

[providers.consulCatalog]

--providers.consulcatalog=true

为服务附加标签（向 Consul 注册服务时）

consul services register -name=my-service -tag="traefik.http.routers.my-service.rule=Host(`example.com`)"

或者使用服务定义文件：

{
  "service": {
    "name": "my-service",
    "tags": [
      "traefik.http.routers.my-service.rule=Host(`example.com`)"
    ]
  }
}

将发往 http://example.com 的请求转发至 http://<private IP of container>:12345：

{
  "service": {
    "name": "my-service",
    "tags": [
      "traefik.http.routers.my-service.rule=Host(`example.com`)",
      "traefik.http.routers.my-service.service=my-service",
      "traefik.http.services.my-service.loadbalancer.server.port=12345"
    ]
  }
}

要将请求转发到同一容器的多个端口，需要使用路由器上的 service 参数引用服务负载均衡器的端口定义。

在此示例中，发往 http://example-a.com 的请求会转发至 http://<private IP of container>:8000，同时，发往 http://example-b.com 的请求会转发至 http://<private IP of container>:9000：

{
  "service": {
    "name": "my-service",
    "tags": [
      "traefik.http.routers.www-router.rule=Host(`example-a.com`)",
      "traefik.http.routers.www-router.service=www-service",
      "traefik.http.services.www-service.loadbalancer.server.port=8000",
      "traefik.http.routers.admin-router.rule=Host(`example-b.com`)",
      "traefik.http.routers.admin-router.service=admin-service",
      "traefik.http.services.admin-service.loadbalancer.server.port=9000"
    ]
  }
}
