如何查看哪个容器正在使用或正在使用哪个Docker卷 [英] How to see which docker volume is or was being used by which container

问题描述

我可以列出所有具有 docker ps（-a）的容器，我可以列出所有具有 docker volume ls ，当我检查量时，可以看到名称，驱动程序和 mountpoint ，但不是使用它的容器。

I can list all containers with docker ps (-a), I can list all volumes with docker volumes ls, when I inspect a volume, I can see the name, driver and mountpoint, but not the container(s) it is being used by.

当我使用 docker inspect< container> ，例如，我可以看到Mount数据：

When I use docker inspect <container>, I can see the Mount data like this for example:

"Mounts": [
    {
        "Name": "centos_db_symfony",
        "Source": "/var/lib/docker/volumes/centos_db_symfony/_data",
        "Destination": "/var/lib/mysql",
        "Driver": "local",
        "Mode": "rw",
        "RW": true,
        "Propagation": "rprivate"
    },

所以从理论上讲，我可以编写一个脚本来循环遍历所有容器，以按名称匹配特定的卷。但是我通过 docker-compose 运行了一些容器，并且没有将名称绑定（例如现在可以在v2中使用）到某些卷，因此它们在sha256中显示为sha256 docker volume ls 列表，像这样：

so in theory, I could write a script that loops through all containers to match a specific volume by name. But I ran some containers through docker-compose, and didn't bind a name (like now is possible in v2) to some volumes, so they show up like a sha256 in the docker volume ls list, like this:

DRIVER              VOLUME NAME
local               34009871ded5936bae81197247746b708c3ec9e9b9832b702c09736a90...etc
local               centos_data
local               centos_db_symfony

在这种情况下，在我在 docker-compose 和 34009871ded5 （示例） > centos_db_symfony 之后。

In this case 34009871ded5 (example) was created before I named the volume in docker-compose and centos_db_symfony after.

当 docker-compose.yml 时卷信息会像在这种情况下那样进行命名，并更新 docker inspect< container> 中的信息，是永远丢失的历史记录还是我能找出哪个容器使用了多少卷？如果是这样，是否还可以还原这样的旧卷？

When docker-compose.yml volume information is updated like in this case making the volume named and the information in docker inspect <container> is updated, is the history forever lost or can I find out which container a volume was used by? If so, is it also possible to restore an old volume like this?

docker-compose version 1.6.0, build d99cad6
Docker version 1.10.2, build c3959b1

推荐答案

从 Docker v1.11 ，您可以按 volume s过滤 ps ！不幸的是，这在以前的版本中不可用。

As of Docker v1.11 you can filter ps by volumes! Unfortunately this is not available in previous versions.

使用方法如下：

docker ps -f "volume=/var/lib/mysql" 

或

docker ps -f "volume=centos_db_symfony"
