Docker环境准备

基础环境

Centos7+git

确认git忽略ssl证书校验

su
echo 'export GIT_SSL_NO_VERIFY=true' >>/etc/bashrc

添加第三方源

sudo yum install epel-release

升级系统

升级的Centos7.2

sudo yum update
sudo yum upgrade

docker环境

安装docker并设置为开机自动启动

sudo chkconfig docker on

利用国内的daocloud.io为docker加速，见相关文档https://www.daocloud.io/mirror#accelerator-doc

curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://db9bd5cd.m.daocloud.io

在daocloud.io上创建本身的帐号，将主机资源加入到daocloud.io中集中管理

su
curl -sSL https://get.daocloud.io/daomonit/install.sh | sh -s e66d49d38c29b6015c7378c08ed8f3ec193c0931
