对于个人开发者来说，在一定情况下很好用。但是对于构建管理项目或者提供构建流程管理的Devops项目而言却是个灾难–本地存储结构不能对用户开放，它们也不能干扰用户本身的构建流程。所幸的是，Moby umbrella的开发团队注意到了这一点，他们希望通过重构存储管理和容器快照来解决一部分问题，于是BuildKit诞生了。

巨坑！
Centos7默认xfs文件系统与docker默认overlay2存储驱动不匹配，会导致容器内文件无法删除等问题

再次遇到这个问题，终于还是发扬刨根问题的精神，经过一上午的百度，google,bing
终于找到根本原因。
这里记录一下，为了帮助后面的人，同时也提醒自己。
问题原因与docker无关，在于linux内核版本。
测试有问题的内核版本是Red Hat 4.8.3-9—对应的发行版是CentOS7.2
