docker创建nginx容器，为什么不能共享nginx.conf文件？

Question

通过命令执行

sudo docker run --name nginx -d -p 80:80 -v $PWD/nginx/conf:/etc/nginx
nginx

容器创建成功，但是无法启动.

通过日志可以看见
`
2017/05/24 12:13:34 [emerg] 1#1: open() "/etc/nginx/nginx.conf" failed (2: No such file or directory)
nginx: [emerg] open() "/etc/nginx/nginx.conf" failed (2: No such file or directory)
`

如果我共享的是/etc/nginx/conf.d目录是没问题的。请问这是为什么，是权限的问题吗？

哇，哥们，你直接把nginx给干掉啦。nginx的很多文件都在/etc/nginx下，别这么挂载，直接挂载一个文件就行了

$sudo docker run --name nginx -d -p 80:80 -v $PWD/nginx/nginx.conf:/etc/nginx/nginx.conf:ro nginx

下面是我用docker-compose编排得例子

services:
  nginx:
    build: ./dockerfiles/nginx/
    container_name: nginx-server
    ports:
      - "80:80"
    links:
      - "php-fpm"
      - "webpack-dev-front"
    volumes:
#网站目录
      - ./app:/var/www/html
      - ./dockerfiles/nginx/conf.d:/etc/nginx/conf.d:ro
      - ./dockerfiles/nginx/nginx.conf:/etc/nginx/nginx.conf:ro
#日志文件
      - ./logs/nginx:/var/log/nginx
