windows安装docker

docker不支持在windows上运行，必须借助docker-machine。docker提供了toolbox用于在windows和mac平台安装docker。
工具箱包括：

• docker machine
• Docker Engine
• Kitematic
• docker命令行运行环境
• Oracle VM VirtualBox

安装之前需要检查BIOS中虚拟化的设置是否已打开，参考此页面

1. 下载安装文件
   https://www.docker.com/toolbox

2. 双击安装文件进行安装

3. 运行docker run hello-world

   运行时出现下面的问题

   Post http://127.0.0.1:2375/v1.20/containers/create: dial tcp 127.0.0.1:2375: ConnectEx tcp: No connection could be made because the target machine actively refused it..
       * Are you trying to connect to a TLS-enabled daemon without TLS?
       * Is your docker daemon up and running?
   

   如下解决：

   docker-machine regenerate-certs default
   docker-machine restart default
   

   显示环境变量：

       $ docker-machine env default --shell sh
           export DOCKER_TLS_VERIFY="1"
           export DOCKER_HOST="tcp://192.168.99.100:2376"
           export DOCKER_CERT_PATH="C:\Users\apex\.docker\machine\machines\default"
           export DOCKER_MACHINE_NAME="default"
           # Run this command to configure your shell:
           # eval "$(E:\04_Program Files\docker_toolbox\Docker Toolbox\docker-machine.exe env default)"
   

   设置环境变量：

   eval "$(docker-machine env default --shell sh)"
   

   再次运行：

   $ docker run hello-world
   Unable to find image 'hello-world:latest' locally

   Hello from Docker.
   This message shows that your installation appears to be working correctly.
   
   To generate this message, Docker took the following steps:
    1. The Docker client contacted the Docker daemon.
    2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    3. The Docker daemon created a new container from that image which runs the
       executable that produces the output you are currently reading.
    4. The Docker daemon streamed that output to the Docker client, which sent it
       to your terminal.
   
   To try something more ambitious, you can run an Ubuntu container with:
    $ docker run -it ubuntu bash
   
   Share images, automate workflows, and more with a free Docker Hub account:

   配置加速器：

   docker-machine ssh default
   sudo sed -i "s|EXTRA_ARGS='|EXTRA_ARGS='--registry-mirror=http://efa65984.m.daocloud.io |g" /var/lib/boot2docker/profile
   exit
   docker-machine restart default
   

备忘：
docker用户的密码是tcuser
可用于winscp传输文件
