traefik为什么要在前端规则中添加“ docker”部分？

Question

我以docker-compose开始一些docker容器，并期望traefik根据容器的名称和域自动创建Host规则。这就是我过去一直拥有的。

通过traefik.toml在domain = "example.com"中设置了域，并且规则模板保留为默认值。

问题在于主机规则的名称中包含.docker.元素部分：

{
  "docker":{
    "backends":{
      "backend-traefik-docker":{
        "servers":{
          "server-docker-traefik-1-b8a648f1d4e2b692fb0a888a6a920124":{
            "url":"http://172.22.0.4:80",
            "weight":1
          }
        },
        "loadBalancer":{
          "method":"wrr"
        }
      },
      "backend-web-docker":{
        "servers":{
          "server-docker-web-1-5d8b13ed7d68cab587a76ca7083edea3":{
            "url":"http://172.22.0.3:80",
            "weight":1
          }
        },
        "loadBalancer":{
          "method":"wrr"
        }
      },
      "backend-whoami-docker":{
        "servers":{
          "server-docker-whoami-1-b63b00b9e018119bfbb2dee19bcc8f9e":{
            "url":"http://172.22.0.2:80",
            "weight":1
          }
        },
        "loadBalancer":{
          "method":"wrr"
        }
      }
    },
    "frontends":{
      "frontend-Host-nginx-docker-localhost-1":{
        "entryPoints":[
          "http"
        ],
        "backend":"backend-web-docker",
        "routes":{
          "route-frontend-Host-nginx-docker-localhost-1":{
            "rule":"Host:nginx.docker.localhost"
          }
        },
        "passHostHeader":true,
        "priority":0,
        "basicAuth":null
      },
      "frontend-Host-traefik-docker-example-com-2":{
        "entryPoints":[
          "http"
        ],
        "backend":"backend-traefik-docker",
        "routes":{
          "route-frontend-Host-traefik-docker-example-com-2":{
            "rule":"Host:traefik.docker.example.com"
          }
        },
        "passHostHeader":true,
        "priority":0,
        "basicAuth":null
      },
      "frontend-Host-whoami-docker-example-com-0":{
        "entryPoints":[
          "http"
        ],
        "backend":"backend-whoami-docker",
        "routes":{
          "route-frontend-Host-whoami-docker-example-com-0":{
            "rule":"Host:whoami.docker.example.com"
          }
        },
        "passHostHeader":true,
        "priority":0,
        "basicAuth":null
      }
    }
  }
}

例如，Host:whoami.docker.example.com实际上应该是Host:whoami.example.com（没有.docker.来自某个地方）。

配置文件非常混合（我在defaultRule中尝试使用traefik.toml和不使用# cat docker-compose.yaml version: '3' services: traefik: image: traefik ports: - "80:80" - "8082:8080" volumes: - $PWD/traefik/traefik.toml:/etc/traefik/traefik.toml whoami: image: containous/whoami web: image: nginx # cat traefik/traefik.toml debug = true [entryPoints] [entryPoints.http] address = ":80" [docker] endpoint = "tcp://192.168.10.2:2375" domain = "example.com" defaultRule = "Host(`{{ normalize .Name }}`)" watch = true exposedByDefault = true usebindportip = true swarmMode = false swarmModeRefreshSeconds = 15 network = "web" [api] dashboard = true ）：

注意：我知道我可以在service（即docker-compose.yaml）的'traefik.frontend.rule=Host:thecontainername.example.com'定义中添加一个declare @outgoings_weight table(space_type varchar(max), w numeric(2,1)); declare @rental_weight table(space_type varchar(max), space_quality varchar(max), campuse_cost varchar(max), w numeric(2,1)); ，但我想设置默认行为。
