前言
Docker出生时就知道，开始感觉和虚拟机技术差不多，也参加过一、二次线下的研讨会，一直想在WINDOWS中使用，安装过1，2次都没有成功。
最近2周才在WINDOWS2016中看了一下，也费尽九牛二虎之力才整成功地从阿里云上PULL了nanoserver.
最近2天遇到Ubuntu18.04发布，成功在docker中运行了tomcat 。

Docker 在Ubuntu 18.04中
配置阿里云docker镜像加速器
使用阿里云加速，下载速度快，有1MB多：
https://dev.aliyun.com/search.html
使用加速器将会提升您在国内获取Docker官方镜像的速度！
您的专属加速器地址 https://?????.mirror.aliyuncs.com
如何配置镜像加速器
- 针对Docker客户端版本大于1.10.0的用户
您可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器：
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://????????.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
PULL了17个镜像image，速度非常快
