Docker Volume：Docker Volume无法在Amazon Linux上正确安装

我目前正在尝试使用ansible将docker注册表部署到Amazon ec2.我的食谱中的任务看起来像这样：

- name: run docker registry container
  docker:
    image: registry
    name: docker-registry
    state: reloaded
    env:
      SETTINGS_FLAVOR: local
      STORAGE_PATH: /opt/docker-registry
      SEARCH_BACKEND: sqlalchemy
    volumes:
    - "/data/docker-registry-server/opt/docker-registry:/opt/docker-registry"
    ports:
    - "5000:5000"

如您所见,注册表部署为docker中的容器.
这在某种程度上起作用.容器正确启动,但卷未正确安装.我通过运行检查了这个：

docker exec -t -i docker-registry touch /opt/docker-registry/touch.me

这将在应安装卷的文件夹中的容器中创建一个新文件.所以这个文件应该出现在/ data / docker-registry-server / opt / docker-registry中的主机上,但它不会.

运行docker inspect docker-registry时我得到了这个结果：

]

这看起来像容器本身知道它应该使用一个卷. Volumes条目列出了正确的路径.所以这很可能是一个码头工人,而不是一个安塞问题.

我正在使用docker 1.5.0,构建a8a31ed / 1.5.0

在这一点上,我确信在如何使用卷方面很可能存在一个愚蠢的错误. (很可能是我的错……)

谁能告诉我哪里出错了？

最佳答案

既然你说通过移动你正在安装的文件夹它可以工作,我会检查一些事情：

>确保您正在装载的目录实际存在于主机上.
>确保您运行ansible playbook的用户具有访问您尝试安装的文件夹的正确权限.
