与systemd traefik没有看到容器码头

Question

我想启动traefik槽systemd，但我没有与systemd vs手动启动相同的结果。

下面是当我traefik手动启动的例子：

$ traefik --web \ 
    --docker \ 
    --docker.domain=docker 


$ docker ps -q 
164f73add870 


$ # check traefik api 
$ http http://localhost:8080/api/providers 
http http://localhost:8080/api/providers 
HTTP/1.1 200 OK 
Content-Length: 377

{ 
    "docker": { 
     "backends": { 
      "backend-rancher": { 
       "loadBalancer": { 
        "method": "wrr" 
       }, 
       "servers": { 
        "server-rancher": { 
         "url": "http://172.17.0.2:8080", 
         "weight": 0 
        } 
       } 
      } 
     }, 
     "frontends": { 
      "frontend-Host-rancher-docker": { 
       "backend": "backend-rancher", 
       "basicAuth": [], 
       "entryPoints": [ 
        "http" 
       ], 
       "passHostHeader": true, 
       "priority": 0, 
       "routes": { 
        "route-frontend-Host-rancher-docker": { 
         "rule": "Host:rancher.docker" 
        } 
       } 
      } 
     } 
    } 
} 

当我使用systemd：

$ sudo systemctl status traefik 
● traefik.service - Traefik reverse proxy 
    Loaded: loaded (/usr/lib/systemd/system/traefik.service; enabled; vendor preset: disabled)

$ docker ps -q

任何想法，为什么我看不到我的集装箱码头工人？
