数据卷的内容，这句话怎么理解呢

Question

When you create a volume, it is stored within a directory on the Docker host. When you mount the volume into a container, this directory is what is mounted into the container. This is similar to the way that bind mounts work, except that volumes are managed by Docker and are isolated from the core functionality of the host machine.

特别是最后一句 except that volumes are managed by Docker and are isolated from the core functionality of the host machine.

这个 core functionality 是什么呢~

数据卷可以由docker管理，宿主机的程序不能直接使用数据卷

  嗯 也只能这么理解了 不能直接使用应该也只是因为数据目录太深了 不好找 而不是不能修改吧~

  可以修改，但是需要有root权限
