匿名/具名挂载

一、

1.匿名挂载

[root@localhost ~]# docker run  -d -P --name nginx01 -v /etc/nginx nginx
Unable to find image 'nginx:latest' locally

2.查看

[root@localhost ~]# docker volume ls
DRIVER    VOLUME NAME

二、 

1.具名挂载

-v 容器内路径！

[root@localhost ~]# docker run  -d -P  --name nginx101 -v  juming-nginx:/etc/nginx  nginx

2.查看所有volume信息

[root@localhost ~]# docker volume ls

DRIVER    VOLUME NAME

local     juming_nginx

3.查看这个卷

[root@localhost ~]# docker volume inspect juming_nginx 
[
    {
        "CreatedAt": "2024-05-29T18:39:54+08:00",
        "Driver": "local",
        "Labels": null,
        "Mountpoint": "/var/lib/docker/volumes/juming_nginx/_data",
        "Name": "juming_nginx",
        "Options": null,
        "Scope": "local"
    }
]

所有的docker容器内的卷，没有指定目录的情况下都是在  /var/lib/docker/volumes/juming_nginx/_data 

具名挂载方便查找，大多数使用具名挂载。

-v 容器内路径        #匿名挂载

-v 卷名：容器内路径        #具名挂载

-v  /宿主机路径：：容器内路径    #指定路径挂载

#通过-v 容器内路径：ro rw改变读写权限

#一旦设置权限，容器对我们挂载内容就有限制！

docker run  -d -P --name nginx101 -v juming_nginx:/etc/nginx：ro nginx
