Mac OS X Yosemite 10.10.5使用Toolbox安装Docker

之前在文章《 Mac OS X Yosemite 10.10.1安装Docker》中介绍了如何使用Boot2Docker在Mac上安装Docker，时隔变迁，现在Boot2Docker已经被官方废弃，取而代之的是Toolbox。

关于boot2docker的说明：

This project (the boot2docker OS X Installer) is officially deprecated in favor of the new Docker Toolbox.

关于Toolbox的说明：

The Docker Toolbox is an installer to quickly and easily install and setup a Docker environment on your computer.
Available for both Windows and Mac, the Toolbox installs Docker Client, Machine, Compose (Mac only) and Kitematic.

Note: 目前Toolbox仅支持Windows和Mac版本。

下面根据官方Toolbox的安装说明，体验新工具带来了哪些新的功能。

Mac OS X users use Docker Toolbox to install Docker software. Docker Toolbox includes the following Docker tools:

• Docker CLI client for running Docker Engine to create images and containers
• Docker Machine so you can run Docker Engine commands from Mac OS X terminals
• Docker Compose for running the docker-compose command
• Kitematic, the Docker GUI
• the Docker QuickStart shell preconfigured for a Docker command-line environment
• Oracle VM VirtualBox

Because the Docker Engine daemon uses Linux-specific kernel features, you can’t run Docker Engine natively in OS X. Instead, you must use the Docker Machine command, docker-machine, to create and attach to a small Linux VM on your machine. This VM hosts Docker Engine for you on your Mac.

1 前提要求

Your Mac must be running OS X 10.8 “Mountain Lion” or newer to run Docker software.

2 下载Toolbox

下载 Docker Toolbox，174MB。

By default, the standard Docker Toolbox installation:

• installs binaries for the Docker tools in /usr/local/bin
• makes these binaries available to all users
• updates any existing Virtual Box installation

下载完成后开始安装：
PS: 在开始安装Toolbox前，需要使用命令boot2docker stop先退出VM服务，如果事先运行了boot2docker的话。

在安装向导中可以看到，会安装哪些工具，以及这些工具安装后的路径。总共需要占用465.9MB的磁盘空间：

在安装过程中，会提示选择一个工具来启动Docker：
* Docker Quickstart Terminal
* Kitematic (Beta) - Visual Management for Docker

我们选择第一个。（这里也可以不选择，直接继续完成安装，在安装完成后再启动）

假如上面选择了第一个，然后会激活一个终端，并显示如下内容：

docker is configured to use the default machine with IP 192.168.99.100
For help getting started, check out the docs at https://docs.docker.com

上面内容总结一句话：

The terminal does a number of things to set up Docker Quickstart Terminal for you.

查看安装目录下的文件变化：

同时在应用程序中多了两个应用图标：

然后根据上面的提示完成启动Docker daemon：

gerryyang@mba:bin$docker run hello-world
docker: Cannot connect to the Docker daemon. Is the docker daemon running on this host?.
See 'docker run --help'.
gerryyang@mba:bin$/usr/local/bin/docker-machine env default
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.99.100:2376"
export DOCKER_CERT_PATH="/Users/gerryyang/.docker/machine/machines/default"
export DOCKER_MACHINE_NAME="default"
# Run this command to configure your shell: 
# eval $(/usr/local/bin/docker-machine env default)

最后，就可以下载镜像和运行容器了：

补充说明：
之前在Mac上使用brew安装的Docker，可以使用下面命令将其删除。

$brew uninstall docker
Uninstalling /usr/local/Cellar/docker/1.4.1... (9 files, 7.0M)
