admin@ubuntu:/mnt/data/web$ sudo docker exec web-server -i -t /bin/bash
rpc error: code = 13 desc = invalid header field value "oci runtime error: exec failed: container_linux.go:247: starting container process caused \"exec: \\\"-i\\\": executable file not found in $PATH\"\n"

顺便，我还有个问题，我的dockerfile文件内容如下

FROM ubuntu:latest
RUN apt-get -qq update
RUN apt-get install -qqy nginx php-fpm php-mcrypt
RUN rm -rf /var/lib/apt/lists/*
EXPOSE 80 443
CMD ["/etc/init.d/nginx", "start"]                               

我build好之后，运行之后容器会退出，然后我start:

admin@ubuntu:/mnt/data/web$ sudo docker start -a -i web-server
cat: /etc/nginx/nginx.conf: No such file or directory
 * Starting nginx nginx
   ...fail!

就这样。这是怎么回事？
我run的命令如下:

sudo docker run --name web-server --link db-mysql:mysql -v /mnt/data/web/htdocs -v /mnt/data/web/nginx.conf.d:/etc/nginx -p 80:80 -p 443:443 -d nginx-php:latest

我都在公司在虚拟机里面都试过了一边，回家跑到我的vps上去搞，就是搞不成，气死我。。。。。
