我正在尝试在nginx.service上启动一个文件nginx.service中的服务：
[Unit] Description=nginx [Service] User=core TimeoutStartSec=0 EnvironmentFile=/etc/environment ExecStartPre=-/usr/bin/docker stop nginx ExecStartPre=-/usr/bin/docker rm nginx ExecStart=/usr/bin/docker run --rm --name nginx -v /home/core/nginx/conf:/etc/nginx/conf:ro -p 80:80 nginx:latest # ExecStop=-/usr/bin/docker stop nginx ExecStopPost=-/usr/bin/docker rm nginx Restart=always RestartSec=10s [X-Fleet]
当我使用fleetctl start nginx.service ，它显示没有错误，但是当我尝试访问该站点时，
Aug 24 15:00:09 core-01 docker[2839]: 172.17.8.1 - - [24/Aug/2016:15:00:09 +0000] "GET / HTTP/1.1" 403 571 "-" "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.116 Safari/537.36" "-" Aug 24 15:00:09 core-01 docker[2839]: 2016/08/24 15:00:09 [error] 5#5: *1 directory index of "/usr/share/nginx/html/" is forbidden, client: 172.17.8.1, server: localhost, request: "GET / HTTP/1.1", host: "172.17.8.101" Aug 24 15:00:09 core-01 docker[2839]: 2016/08/24 15:00:09 [error] 5#5: *1 open() "/usr/share/nginx/html/favicon.ico" failed (2: No such file or directory), client: 172.17.8.1, server: localhost, request: "GET /favicon.ico HTTP/1.1", host: "172.17.8.101", referrer: "http://172.17.8.101/" Aug 24 15:00:09 core-01 docker[2839]: 172.17.8.1 - - [24/Aug/2016:15:00:09 +0000] "GET /favicon.ico HTTP/1.1" 404 571 "http://172.17.8.101/" "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.116 Safari/537.36" "-"
但是，如果我从船队文件启动docker命令：
/usr/bin/docker run --rm --name nginx -v /home/core/nginx/conf:/etc/nginx/conf:ro -p 80:80 nginx:latest
它正常运行并显示正确的页面。
我做错了什么，如何解决？
