docker 容器卷

创建各种卷

[root@docker ~]# docker volume create mqy-vo101

mqy-vo101

[root@docker ~]# docker inspect mqy-vo101

[

{

"CreatedAt": "2022-04-27T16:12:45+08:00",

"Driver": "local",

"Labels": {},

"Mountpoint": "/var/lib/docker/volumes/mqy-vo101/_data",

"Name": "mqy-vo101",

"Options": {},

"Scope": "local"

}

]

[root@docker ~]# docker volume create --driver local \

--opt type=tmpfs

--opt device=tmpfs

--opt o=size=100m,uid=1000

mqy-vo

mqy-vo

[root@docker ~]# docker inspect mqy-vo

[

{

"CreatedAt": "2022-04-27T16:14:18+08:00",

"Driver": "local",

[root@docker ~]# docker volume create --label city=wuhan mqy-vo3

mqy-vo3

[root@docker ~]# docker inspect mqy-vo3

[

{

"CreatedAt": "2022-04-27T16:14:56+08:00",

"Driver": "local",

"Labels": {

"city": "wuhan"

},

"Mountpoint": "/var/lib/docker/volumes/mqy-vo3/_data",

"Options": {},

    "Scope": "local"
}

]

显示卷

[root@docker ~]# docker volume ls

没有被使用的卷

[root@localhost volumes]# docker volume ls -f dangling=true

驱动为local的卷

[root@localhost volumes]# docker volume ls -f driver=local

根据label元数据筛选

[root@localhost volumes]# docker volume ls --filter label=city

根据名称筛选

[root@localhost volumes]# docker volume ls -f name=03

只打印卷名

[root@localhost volumes]# docker volume ls -q

内容过滤输出

[root@localhost volumes]# docker volume ls --format "{{.Name}}: {{.Driver}}"

[root@localhost volumes]# docker volume ls --format "{{.Name}}: {{.Mountpoint}}: {{.Labels}}"

查看卷详情

[root@docker ~]# docker volume inspect --help

-f, --format string Format the output using the given Go template

[root@docker ~]#

创建一个卷并查看信息

[root@docker ~]# docker volume create --driver local \

--opt type=tmpfs

--opt device=tmpfs

--opt o=size=100m,uid=1000

--label city=wuhan

--label type=tmpfs

test-vo1

test-vo1

[root@docker ~]# docker volume inspect test-vo1

[

{

"CreatedAt": "2022-04-27T16:42:21+08:00",

}

]

[root@docker ~]#

找到这个卷并查看挂载点

[root@docker ~]# docker volume inspect --format '{{ .Mountpoint}}' test-vo1

/var/lib/docker/volumes/test-vo1/_data

找到这个卷的元数据

[root@docker ~]# docker volume inspect --format '{{ .Options }}' test-vo1

map[device:tmpfs o:size=100m,uid=1000 type:tmpfs]

简略元数据

[root@hqs ~]# docker volume inspect --format '{{ .Options.o }}' test-vol

size=100m,uid=1000

元数据地址

[root@hqs ~]# docker volume inspect --format '{{ .Labels.city }}' test-vol
