• 基于本地文件系统的Volume。可以在执行Docker create或者Docker run时候,通过-V参数将主机的目录作为容器的数据卷,这部分功能便是基于本地文件系统的Volume管理。

  • 基于Plugin的Volume,支持第三方的存储方案


  • 受管理的datae Volume,由docker后台自动创建

  • 绑定挂载的Volume,具体挂载位置可以由用户来指定位置

Data Volume



Data Volume的语法
        docker run -v 自定义的名称:/保存在真机硬盘的位置
docker run -d -v mysql:/var/lib/mysql --name my_mysql -e MYSQL_ALLOW_EMPTY_PASSWORD=true mysql

2.查看docker volume

docker volume ls


docker exec -it my_mysql /bin/bash  #进入容器并且创建新的终端
root@5208bb137409:/#mysql -e "create database cc;"      #创建数据库
root@5208bb137409:/#mysql -e "create table cc.ff(id int,name char(10),age int(5));"     #创建表
docker stop my_mysql
docker rm my_mysql


docker run -d -v mysql:/var/lib/mysql --name mysql_2 -e MYSQL_ALLOW_EMPTY_PASSWORD=true mysql       #创建新的数据库名字为mysql_2指定docker volume的地址
docker exec -it mysql_2 /bin/bash       #进入mysql_2的容器
mysql -e "show databases;"      #存在证明我们的持久化成功

Bind Mouting


        docker run -v 容器中的目录:/宿主机的目录    #容器里面的目录和我们的宿主机的目录同步


mkdir /nginx
cd /nginx;echo "hello word">index.html
docker run -d -p 80:80 -v $(pwd):/usr/share/nginx/html --name web   创建Nginx的容器,端口映射,将当前的目录传递给我们的docker
        Hello word      #成功访问并映射到容器中
