Docker安裝Nginx掛載數據卷

1. 首先啟動一個Nginx容器

docker run --name my-nginx -p 8080:8080 -d nginx

2. 進入容器

docker exec -it my-nginx bash

3. 查看Nginx的html、配置和日志目錄

• /etc/nginx：配置文件的目錄
• /usr/share/nginx/html：html目錄
• /var/log/nginx：日志目錄

root@33aab93c60f7:/# find / -name nginx
/etc/default/nginx
/etc/init.d/nginx
/etc/logrotate.d/nginx
/etc/nginx
find: '/proc/1/map_files': Operation not permitted
find: '/proc/31/map_files': Operation not permitted
find: '/proc/32/map_files': Operation not permitted
find: '/proc/38/map_files': Operation not permitted
/usr/lib/nginx
/usr/sbin/nginx
/usr/share/doc/nginx
/usr/share/nginx
/var/cache/nginx
/var/log/nginx

4. exit退出容器，在/opt下創建nginx目錄用來存放html、配置和日志目錄

mkdir /opt/nginx

5. 拷貝容器中nginx的配置目錄到/opt/nginx，並改名為conf

docker cp my-nginx:/etc/nginx /opt/nginx

mv /opt/nginx/nginx /opt/nginx/conf

6. 刪除容器

docker rm -f my-nginx

7. 啟動nginx容器並掛載目錄

docker run -p 80:80 --name nginx \
	-v /opt/nginx/conf:/etc/nginx \
	-v /opt/nginx/html:/usr/share/nginx/html \
	-v /opt/nginx/log:/var/log/nginx \
	-d nginx
