Docker学习笔记 05数据挂载 docker

容器数据卷指定路径挂载

-v 宿主机目录:容器目录

docker run -it -v 宿主机目录:容器目录 centos /bin/bash#查看挂载信息 docker inspect 容器ID"Mounts": [ { "Type": "bind", "Source": "宿主机目录", "Destination": "容器目录", ... } ]

匿名挂载

-v 容器目录

docker run -d -P --name test1 -v /testnginx-P 随机开放端口#查看所有volume信息 docker volume lsDRIVERVOLUME NAME localccae06dda8374c37d25321b266e1d77eb786594f1aa9dfb861eb6097114d78da#查看具体挂载 docker volume inspect ccae06dda8374c37d25321b266e1d77eb786594f1aa9dfb861eb6097114d78da[ { "CreatedAt": "2021-08-01T20:09:40+08:00", "Driver": "local", "Labels": null, "Mountpoint": "/var/lib/docker/volumes/ccae06dda8374c37d25321b266e1d77eb786594f1aa9dfb861eb6097114d78da/_data", "Name": "ccae06dda8374c37d25321b266e1d77eb786594f1aa9dfb861eb6097114d78da", "Options": null, "Scope": "local" } ]

具名挂载
具名挂载可以方便的找到我们的卷，使用较多

-v 卷名:容器目录

docker run -d -P --name test2 -v test-name:/testnginx #查看所有volume信息 docker volume lsDRIVERVOLUME NAME localtest-name#查看具体挂载 docker volume inspect test-name[ { "CreatedAt": "2021-08-01T20:12:29+08:00", "Driver": "local", "Labels": null, "Mountpoint": "/var/lib/docker/volumes/test-name/_data", "Name": "test-name", "Options": null, "Scope": "local" } ]

docker默认挂载目录:/var/lib/docker/volumes/...
拓展
-v 通过容器内路径:ro/rw 改变读写权限

ro readonly#只读（容器内无法修改，只能通过宿主机操作） rw readwrite #可读可写（默认）

Mysql数据挂载官方文档：https://hub.docker.com/_/mysql

#获取镜像 docker pull mysql:5.7#数据挂载 docker run -d -p 3310:3306 \ -v /home/mysql/conf:/etc/mysql/conf.d \ -v /home/mysql/data:/var/lib/mysql \ -e MYSQL_ROOT_PASSWORD=密码 \ --name 容器名称 \ mysql:5.7
