創建測試檔案

			
# mkdir -p /www/netkiller.cn/www.netkiller.cn
# echo Helloworld > /www/netkiller.cn/www.netkiller.cn/index.html
# cat /www/netkiller.cn/www.netkiller.cn/index.html
Helloworld
# exit
exit
			
		

			
# docker volume inspect WebVolume1

容器一

			
# docker run -ti --name=Container1 -v DataVolume1:/opt/data ubuntu
			
		

容器二

			
# docker run -ti --name=Container2 --volumes-from Container1 ubuntu
			
		

進入容器一中查看數據

			
# docker start -ai Container1
			
		

容器三，掛在只讀卷

			
# docker run -ti --name=Container3 --volumes-from Container2:ro ubuntu
			
		

刪除上面三個測試容易和卷

			
# docker rm Container1 Container2 Container3
# docker volume rm DataVolume1
			
		

			
# docker run -it --name mycentos1 -v /www:/tmp/test docker.io/centos:7 /bin/bash
# docker run -d -v ~/logs:/var/log/nginx -p 80:80 -i nginx			
			
		

/etc/redis/redis.conf:/etc/redis/redis.conf:ro 表示只讀權限
