docker machine 使用教程

之前，Docker的安装流程非常复杂，用户需要登录到相应的主机上，根据官方的安装和配置指南来安装Docker，并且不同的操作系统的安装步骤也是不一样的。而有了Machine后，不管是在笔记本、虚拟机还是公有云实例上，用户仅仅需要一个命令....当然那你需要先安装Machine。感觉这玩意对开发很有用因为开发的电脑系统五花八门，生产环境一般都是运维部署的统一操作系统安装docker环境用脚本就行了

准备环境：

VirtualBox  Git Bash（windows）  翻墙(你懂得)

安装 Docker Machine

macOS:

$ curl -L https://github.com/docker/machine/releases/download/v0.13.0/docker-machine-`uname -s`-`uname -m` >/usr/local/bin/docker-machine && 
  chmod +x /usr/local/bin/docker-machine

Linux:

$ curl -L https://github.com/docker/machine/releases/download/v0.13.0/docker-machine-`uname -s`-`uname -m` >/tmp/docker-machine &&
chmod +x /tmp/docker-machine &&
sudo cp /tmp/docker-machine /usr/local/bin/docker-machine

Windows with Git BASH:

$ if [[ ! -d "$HOME/bin" ]]; then mkdir -p "$HOME/bin"; fi && 
curl -L https://github.com/docker/machine/releases/download/v0.13.0/docker-machine-Windows-x86_64.exe > "$HOME/bin/docker-machine.exe" && 
chmod +x "$HOME/bin/docker-machine.exe"

 $ docker-machine ls

  To see how to connect Docker to this machine, run: docker-machine env default

 $ docker-machine ls
