在按照docker官网的安装步骤安装好后，运行hello-world结果出现：
:~$ sudo docker run hello-worldUnable to find image ’hello-world:latest’ locallydocker: Error response from daemon: Get https://registry-1.docker.io/v2/: write tcp 10.11.66.20:49182->50.17.62.194:443: write: connection reset by peer.See ’docker run --help’.:~$ sudo docker login -u'gaoxi1993' -p'xxx'Error response from daemon: Get https://registry-1.docker.io/v2/: Get https://auth.docker.io/token?account=gaoxi1993&client_id=docker&offline_token=true&service=registry.docker.io: read tcp 10.11.66.20:48290->50.17.62.194:443: read: connection reset by peer

2017年03月12日19:52补充换到家里的网络重启电脑后，第一次会出现

貌似是网络环境问题，真是见鬼了，目前已正常使用。
问题解答
回答1：国内的网络原因你懂的。可以使用一些国内的docker镜像，比如daocloud，时速云，灵雀云等，他们都提供了镜像加速
回答2：docker在使用的时候,很多命令需要调用/var/run/docker.sock但是docker.sock需要较高的权限.解决方法:1.docker.sock权限授予用户2.切换到root(ubuntu 使用 sudo su 切换)
回答3：同样的docker版本，已加入docker用户组，也是遇到这个问题。同样的命令，一会儿报：
Error response from daemon: Get https://registry-1.docker.io/... read tcp 192.168.1.170:49652->50.17.62.194:443: read: connection reset by peer
再过一会运行又是正常的，不知道网络哪里出问题了
2017-03-26改为使用中科大的源了，速度还比较快https://lug.ustc.edu.cn/wiki/...
