Mac 安装Docker

brew search docker

首先查找Docker相关安装包

$ brew search docker

==> Formulae
docker                            docker-compose-completion         docker-ls                         docker-machine-driver-vmware      docker-machine-parallels          docker2aci
docker-clean                      docker-credential-helper          docker-machine                    docker-machine-driver-vultr       docker-slim                       dockerize
docker-completion                 docker-credential-helper-ecr      docker-machine-completion         docker-machine-driver-xhyve       docker-squash                     lazydocker
docker-compose                    docker-gen                        docker-machine-driver-hyperkit    docker-machine-nfs                docker-swarm
==> Casks
docker                                                              docker-toolbox                                                      homebrew/cask-versions/docker-edge

brew info docker

可以观察到有两个Docker安装包，分别查看下两个包的具体详情

$ brew info docker

docker: stable 19.03.7 (bottled)
Pack, ship and run any application as a lightweight container
https://www.docker.com/
Not installed
From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/docker.rb

$ brew cask info docker

Docker.app (App)

从详情下可以看出，cask下的是桌面版"Docker Desktop"，然后就可以开始安装桌面版了

brew cask install docker

$ brew cask install docker

🍺 docker was successfully installed!

安装完成后，可以在启动台里找到Docker.app，打开后顶部菜单栏也会出现docker logo，至此Mac下的Docker就安装成功了，就可以enjoy it了，具体配置可根据自己需要进行设置。
