我发现可以通过brew / cask获得Docker Toolbox

# Install Homebrew
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
# Install Cask
brew install caskroom/cask/brew-cask
# Install docker toolbox
brew cask install docker-toolbox

安装Docker Toolbox后，您可以使用Docker Machine入门指南设置Docker环境。

# create the docker machine
docker-machine create --driver "virtualbox" myBoxName

# start the docker machine
docker-machine start myBoxName

# this command allows the docker commands to be used in the terminal
eval "$(docker-machine env myBoxName)"

# at this point can run any "docker" or "docker-compose" commands you want
docker-compose up

在此过程结束时，添加eval "$(docker-machine env myBoxName)"到您的，.bash_profile否则在打开新的外壳程序或终端时会出现以下错误。

"Cannot connect to the Docker daemon. Is the docker daemon running on this host?"

如果在打开终端后启动docker容器，则可以eval "$(docker-machine env myBoxName)"手动运行，也可以重新加载bash配置文件（source ~/.bash_profile）。
