使用DockerToolbox在MacOSX上安装Docker

这里利用 Docker Toolbox 来安装 Docker

注意：新版 Docker 版本为了支持 Docker 机不再支持 Boot2Docker 命令行

安装VirtualBox

首先需要安装[VirtualBox]虚拟机软件

地址是：https://www.virtualbox.org/

Step 1: Check your version 检测系统版本

OSX版本必须大于等于10.8 "Snow Leopard" 才可以安装 Docker Toolbox

Version: 10.11.2 (15C50)

Step 2: Install Docker Toolbox

点击 Docker Toolbox 下载链接，进行下载，由于AWS被墙，下载可能要麻烦一些了。

https://www.docker.com/toolbox

Step 3: Verify your installation

（1）Open the Launchpad and locate the Docker Quickstart Terminal icon.
（2）Click the icon to launch a Docker Quickstart Terminal window.
（3）Click your mouse in the terminal window to make it active.
（4）Type the docker run hello-world command and press RETURN.

新创建一个Docker虚拟机

查看所有的Docker虚拟机
$ docker-machine ls

创建一个新的Docker虚拟机，命名为wangdev
$ docker-machine create --driver virtualbox wangdev

$ docker-machine create --driver virtualbox wangdev
Running pre-create checks...
Creating machine...
(wangdev) Copying /Users/wangdev/.docker/machine/cache/boot2docker.iso to /Users/wangdev/.docker/machine/machines/wangdev/boot2docker.iso...
(wangdev) Creating VirtualBox VM...
(wangdev) Creating SSH key...
(wangdev) Starting the VM...
(wangdev) Waiting for an IP...
Waiting for machine to be running, this may take a few minutes...

Copying certs to the remote machine...

Checking connection to Docker...
Docker is up and running!
To see how to connect Docker to this machine, run: docker-machine env wangdev

根据创建成功后的提示，执行： docker-machine env wtest

$ docker-machine env wtest
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.99.102:2376"
export DOCKER_CERT_PATH="/Users/WangTom/.docker/machine/machines/wtest"
export DOCKER_MACHINE_NAME="wtest"
# Run this command to configure your shell:
# eval $(docker-machine env wtest)

再根据提示执行： eval $(docker-machine env wtest)

查看docker虚拟机列表：docker-machine ls

$ docker-machine ls
NAME ACTIVE URL STATE URL SWARM DOCKER ERRORS
default - virtualbox Running tcp://192.168.99.101:2376 v1.9.1

wangdev * virtualbox Running tcp://192.168.99.102:2376 v1.9.1

可以看到 wangdev 在ACTIVE列变成了 星号 ，表示 wangdev 现在是激活状态。

执行 hello-world 容器看看效果：docker run hello-world

$ docker run hello-world
