Ｄug/[docker start]:修复docker daem

上班的时间一直玩k8s，今天休息想在家玩一玩，掏出我的老古董，ubuntu 14，恩～，

systemctl status docker.service

恩～，毕竟２年前的东西，出问题合理，分析一下问题。

ExecStart=/usr/bin/docker daemon -H fd:// (code=exited, status=1/FAILURE)

/usr/bin/docker daemon的启动程序有问题，恩～

{

    "storage-driver": "devicemapper",

    "storage-opts": [

        "dm.thinpooldev=/dev/mapper/docker-thinpool",

        "dm.use_deferred_removal=true",

        "dm.use_deferred_deletion=true"

    ]

}

参看ubuntu给的example
http://manpages.ubuntu.com/manpages/xenial/man8/docker-daemon.8.html

修改所有不必要的配置
  {

                      "storage-driver"
                      :

                      "devicemapper"

  }
~     

systemctl restart docker
success

对比一下２个json file,想起最近遇到的问题，做产品，和这些配置文件一样
都是特征的提取与叠加，简单是不是最好的呢
