本文介绍了在Docker容器中如何列出卷？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
注意：我使用的是Docker 1.3版本.2在Red Hat 7上。
示例
postgres Docker注册表的官方图像为 / var / lib / postgresql / data 中的容器配置了一个卷。
在 postgres / var / lib / postgresql / data c $ c> container？
解决方案
使用 docker ps 容器ID。
然后 docker inspect -f'{{.Volumes}}'containerid
示例：
终端1
$ docker run -it -v / tmp：/ tmp ubuntu：14.04 / bin / bash
终端2
$ docker ps
CONTAINER ID IMAGE COMM并创建状态端口名称
ddb7b55902cc ubuntu：14.04/ bin / bash大约一分钟前Up大约一分钟distracted_banach
$ docker inspect -f{{.Volumes}}ddb7
地图[/ tmp：/ tmp]
输出
map [/ tmp：/ tmp]
显然是由于使用 Go 语言来实现docker命令工具。
docker检查命令，而没有 -f格式是相当冗长的。由于它是JSON，您可以将其管线到python或nodejs并提取所需的任何东西。

docker history< image name> 将显示层图片。不幸的是，码头历史记录似乎被格式化和缺乏选择所选择的选项所困扰。
您可以通过--no-trunc标志来选择简洁和详细的格式。

When using docker images from registries, I often need to see the volumes created by the image's containers.
Note: I'm using docker version 1.3.2 on Red Hat 7.
Example
The postgres official image from the Docker Registry has a volume configured for containers at /var/lib/postgresql/data.
What's the most succinct command to show the volume at /var/lib/postgresql/data in a postgres container?
解决方案
Use docker ps to get the container id.
Then docker inspect -f '{{ .Volumes }}' containerid
Example:
terminal 1
$ docker run -it -v /tmp:/tmp ubuntu:14.04 /bin/bash
terminal 2
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
ddb7b55902cc ubuntu:14.04 "/bin/bash" About a minute ago Up About a minute distracted_banach
$ docker inspect -f "{{ .Volumes }}" ddb7
map[/tmp:/tmp]
The output
map[/tmp:/tmp]
is, apparently, due to the use of the Go language to implement the docker command tools.
The docker inspect command without the -f format is quite verbose. Since it is JSON you could pipe it to python or nodejs and extract whatever you needed.

docker history <image name> will show the layers baked into an image. Unfortunately, docker history seems hobbled by its formatting and lack of options to choose what is displayed.
You can choose terse and verbose formats, via the --no-trunc flag.
