boot2docerk start命令来启动
shengli-mac$ boot2docker start
Waiting for VM and Docker daemon to start...

Writing /Users/shengli/.boot2docker/certs/boot2docker-vm/cert.pem
Writing /Users/shengli/.boot2docker/certs/boot2docker-vm/key.pem
To connect the Docker client to the Docker daemon, please set:
export DOCKER_HOST=tcp://192.168.59.103:2376
export DOCKER_CERT_PATH=/Users/shengli/.boot2docker/certs/boot2docker-vm
export DOCKER_TLS_VERIFY=1 Ps:这里HOST为192.168.59.103,这个就是以后要访问的虚拟机的地址。

Boot2Docker version 1.3.2, build master : 495c19a - Mon Nov 24 20:40:58 UTC 2014
Docker version 1.3.2, build 39fa2fa 四、第一个和第二个Docker程序
对于第一个,相信大家都很了解,Docker版的HelloWorld。这个正好来验证是否安装成功。1. Docker HelloWorld
运行 docker run hello-world,docker会在本地查找镜像是否存在(肯定不存在了,刚装的= =), 然后docker会去远程Docker registry server去下载这个镜像。下载后运行这个镜像。这个镜像程序,会输出一句 Hello from Docker. 如果看到这句话,说明你的Docker已经正确安装了。shengli-mac$ docker run hello-world
Unable to find image 'hello-world' locally
hello-world:latest: The image you are pulling has been verified
511136ea3c5a: Pull complete
7fa0dcdc88de: Pull complete
ef872312fe1b: Pull complete
Status: Downloaded newer image for hello-world:latest
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.
(Assuming it was not already locally available.)
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

http://docs.docker.com/userguide/2、Docker Nginx
这里会演示下载一个Nginx Server的镜像,然后可以通过本机访问Docker的容器端口,从而访问到部署在Docker中的Nginx。
docker run --rm -i -t -p 80:80 nginxshengli-mac$ docker run --rm -i -t -p 80:80 nginx
Unable to find image 'nginx' locally

Status: Downloaded newer image for nginx:latest
运行后,该命令会listen监听访问,如果成功访问,则会看到nginx的log:
192.168.59.3 - - [07/Dec/2014:02:24:06 +0000] "GET / HTTP/1.1" 200 612 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.71 Safari/537.36" "-"

192.168.59.3 - - [07/Dec/2014:02:24:06 +0000] "GET /favicon.ico HTTP/1.1" 404 570 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.71 Safari/537.36" "-"
将nginx镜像运行在Docker的80端口,那么你访问DOCKER_HOST:80将会看到nginx的欢迎页面。
如果你忘记了dock的host,可以使用:boot2docker ipshengli-mac$ boot2docker ip
The VM's Host only interface IP address is: 192.168.59.103五、总结
本文讲解了,如何在Mac OSX安装和部署Docker,没有特别难的步骤,VM启动也是后台进程,很轻量级。
