docker命名卷存储在哪里？ [英] Where docker named volumes are stored?

问题描述

我有这个 docker-compose.yml 文件

version: '3'

volumes:
  jenkins_home:

services:

  registry:
     image: registry:2
     ports:
       - "5000:5000"

  jenkins:
    image: jenkins/jenkins
    ports:
      - "9090:8080"
    volumes:
      - jenkins_home:/var/jenkins_home

，有一个名为 jenkins_home 的卷，现在我想知道，数据真正保留在哪里？

As you can see, there is a named volume called jenkins_home, now I wonder, where does the data get really persisted?

运行 docker inspect infra_jenkins 我明白了：

 ...
 "Mounts": [
    {
      "Type": "volume",
      "Source": "infra_jenkins_home",
      "Target": "/var/jenkins_home",
      "VolumeOptions": {
      "Labels": {
      "com.docker.stack.namespace": "infra"
              }
          }
      }
],
...

我正在使用 docker stack deploy 命令，群集由三个VirtualBox实例组成。

I am running those services on a local docker swarm cluster using docker stack deploy command, the cluster is composed of three VirtualBox instances.
