90~97行的Mounts节点描述了当前容器挂载的”卷”信息。
最后指出一点：目前docker仅支持在run(创建)容器时使用-v创建卷，对于一个已经start的容器，如果想动态添加卷，是十分困难的。虽然国外有牛人，实现了在容器启动后动态添加卷，但过程十分曲折，而且并不能能用，有兴趣的可以参考下面的文章
http://jpetazzo.github.io/2015/01/13/docker-mount-dynamic-volumes/
3.2 列出所有卷
docker volume ls3.3 删除卷
docker volume rm 卷名称注：删除一个容器时，默认不会删除容器关联的卷，所以随着时间的推移，host上可能会存在大量的”僵尸”卷，占用硬盘空间。建议每次docker rm 容器时，加上参数-v，这样删除容器时会一并将对应的卷删除，但是这样也会有一个副作用，如果多个容器同时关联到同一个卷，可能会影响到其它容器。所以在使用卷的时候要规划清楚，最好一个容器只对应一个卷。
