linux - docker建立nginx容器，為什麼不能共享nginx.conf檔案？

Question

透過指令執行

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

#容器建立成功，但是無法啟動.

透過日誌可以看見
`
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目錄是沒問題的。請問這是為什麼，是權限的問題嗎？

哇，哥們，你直接把nginx給幹掉啦。 nginx的許多檔案都在/etc/nginx下，別這麼掛載，直接掛載一個檔案就行了

$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編排到例子

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
