这个问题已经在这里有了答案：            >            Docker: where is docker volume located for this compose file                                    1个
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

如您所见,有一个名为jenkins_home的命名卷,现在我想知道,数据真正保留在哪里？

运行docker inspect infra_jenkins我得到了这个：

 ...
 "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命令在本地docker swarm群集上运行这些服务,该群集由三个VirtualBox实例组成.
