示例

 

创建数据卷：docker volume create my_volume

[root@centos docker]# docker volume create my_volume
my_volume

 

查看数据卷信息

[root@centos docker]# docker volume inspect my_volume
[
    {
        "CreatedAt": "2020-08-23T10:29:12+08:00",
        "Driver": "local",
        "Labels": {},
        "Mountpoint": "/var/lib/docker/volumes/my_volume/_data",
        "Name": "my_volume",
        "Options": {},
        "Scope": "local"
    }
]

宿主机目录：/var/lib/docker/volumes/my_volume/_data

 

 

创建服务时，添加数据卷

[root@centos docker]# docker service create --mount type=volume,source=my_volume,target=/test --name redis redis

overall progress: 1 out of 1 tasks 
1/1: running   [==================================================>] 
verify: Service converged 

 

服务创建后，添加数据卷

[root@centos docker]# docker service update --mount-add type=volume,source=add_volume,target=/test2 redis
redis
overall progress: 1 out of 1 tasks 
1/1: running   [==================================================>] 
verify: Service converged 

 

服务创建后，删除数据卷

[root@centos docker]# docker service update --mount-rm /test2 redis
redis
overall progress: 1 out of 1 tasks 
1/1: running   [==================================================>] 
verify: Service converged
