-f格式的docker inspect
命令非常冗长。因为它是JSON，所以可以通过管道将其传输到python或nodejs，并提取所需的内容

通过检查容器，查看JSON输出并比较几个字段，可以获得关于哪些卷被专门烘焙到容器中的信息。运行docker inspect myContainer
时，Volumes
和VolumesRW
字段为您提供容器中装入的所有卷的信息，包括使用VOLUME
指令装入docker文件的卷，并在命令行上使用docker run-v
命令。但是，通过检查docker inspect
JSON输出中的HostConfig.Binds
字段，可以使用docker run-v
命令隔离容器中装入的卷。为了澄清这一点，此HostConfig.Binds
字段告诉您哪些卷是专门安装在带有-v
选项的docker run
命令中的。因此，如果您将此字段与Volumes
字段交叉引用，您将能够使用Dockerfile中的VOLUME
指令确定哪些卷已烘焙到容器中
grep可以实现以下功能：
$ docker inspect myContainer | grep -C2 Binds
...
"HostConfig": {
"Binds": [
"/var/docker/docker-registry/config:/registry"
],
而且
$ docker inspect myContainer | grep -C3 -e "Volumes\":"
...
"Volumes": {
"/data": "/var/lib/docker...",
"/config": "/var/lib/docker...",
"/registry": "/var/docker/docker-registry/config"
在我的示例中，您可以看到我已经使用我的docker run
命令中的-v
选项将/var/docker/docker registry/config
作为/registry
装入容器，并且我已经使用docker文件中的VOLUME
指令装入/data
和/config
卷。容器不需要运行以获取此信息，但需要至少运行一次，才能填充docker inspect
命令的HostConfig
JSON输出。使用docker 1.10，您现在有了用于数据卷容器的新命令。
（对于常规集装箱，请参见下一节docker 1.8+：
使用docker 1.8.1（2015年8月），docker inspect-f'{.Volumes}}'集装箱ID将为空
您现在需要检查装载
，这是装载路径的列表，如：
"Mounts": [
{
"Name": "7ced22ebb63b78823f71cf33f9a7e1915abe4595fcd4f067084f7c4e8cc1afa2",
"Source": "/mnt/sda1/var/lib/docker/volumes/7ced22ebb63b78823f71cf33f9a7e1915abe4595fcd4f067084f7c4e8cc1afa2/_data",
"Destination": "/home/git/repositories",
"Driver": "local",
"Mode": "",
"RW": true
}
],
如果您想要第一次装载的路径（例如），那将是（使用索引0）：
作为评论：
把整件事都打印出来：
或者，通过使用
对于Docker 1.8，我使用：
$ docker inspect -f "{{ .Config.Volumes }}" 957d2dd1d4e8
map[/xmount/dvol.01:{}]
$
显示容器使用的卷的名称和装入点目标：
docker container inspect \
-f '{{ range .Mounts }}{{ .Name }}:{{ .Destination }} {{ end }}' \
CONTAINER_ID_OR_NAME
这与Docker 1.13兼容。以下是一行命令，用于获取正在运行的容器的卷信息：
for contId in `docker ps -q`; do echo "Container Name: " `docker ps -f "id=$contId" | awk '{print $NF}' | grep -v NAMES`; echo "Container Volume: " `docker inspect -f '{{.Config.Volumes}}' $contId`; docker inspect -f '{{ json .Mounts }}' $contId | jq '.[]'; printf "\n"; done
输出为：
root@ubuntu:/var/lib# for contId in `docker ps -q`; do echo "Container Name: " `docker ps -f "id=$contId" | awk '{print $NF}' | grep -v NAMES`; echo "Container Volume: " `docker inspect -f '{{.Config.Volumes}}' $contId`; docker inspect -f '{{ json .Mounts }}' $contId | jq '.[]'; printf "\n"; done

这是我的版本，用于查找docker compose的装入点。
正在使用此选项备份卷
# for Id in $(docker-compose -f ~/ida/ida.yml ps -q); do docker inspect -f '{{ (index .Mounts 0).Source }}' $Id; done
/data/volumes/ida_odoo-db-data/_data
/data/volumes/ida_odoo-web-data/_data
这是以前解决方案的组合 docker compose用户的有用变体：
docker-compose ps -q | xargs docker container inspect \
-f '{{ range .Mounts }}{{ .Name }}:{{ .Destination }} {{ end }}'
这将非常整洁地输出可解析的卷信息。来自我的wordpress docker compose的示例：
ubuntu@core $ docker-compose ps -q | xargs docker container inspect -f '{{ range .Mounts }}{{ .Name }}:{{ .Destination }} {{ end }}'
core_wpdb:/var/lib/mysql
core_wpcode:/code core_wphtml:/var/www/html
输出为每个容器包含一行，列出了使用的卷（和装入点）。更改{.Name}:{{.Destination}}部分以输出所需的信息
如果您只需要一个简单的卷列表，每行一个
$ docker-compose ps -q | xargs docker container inspect \
-f '{{ range .Mounts }}{{ .Name }} {{ end }}' \
| xargs -n 1 echo
core_wpdb
core_wpcode
core_wphtml
非常适合生成要备份的卷列表。我使用此技术以及备份docker compose中所有容器使用的所有卷。Volumerize的文档不会调用它，但是您不需要在持久容器中使用它，也不需要使用内置的工具来启动和停止服务。我更喜欢将备份和服务控制等关键操作留给实际用户（docker外部）。我的备份由实际（非docker）用户帐户触发，使用docker compose stop停止服务，备份所有正在使用的卷，最后使用docker compose start重新启动 如果要列出所有容器名称以及附加到每个容器的相关卷，可以尝试以下操作：
docker ps -q | xargs docker container inspect -f '{{ .Name }} {{ .HostConfig.Binds }}'
示例输出：
/opt_rundeck_1[/opt/var/lib/mysql:/var/lib/mysql:rw
/var/lib/rundeck/var/storage:/var/lib/rundeck/var/storage:rw
/opt/var/rundeck/.ssh:/var/lib/rundeck/.ssh:rw

/opt_rundeck_1-容器名称
[…]-连接到conatiner的卷如果使用pwsh（powershell core），可以尝试
(docker ps --format='{{json .}}' | ConvertFrom-Json).Mounts
您还可以看到容器名称和装载，如下所示
docker ps --format='{{json .}}' | ConvertFrom-Json | select Names,Mounts
当输出转换为json时，您可以获得它的任何属性。我实际上在谷歌上搜索了这个，并找到了我自己的答案：）我的

-f '{{ range .Mounts }}{{ .Name }} {{ end }}' \
