MacOS Docker Installation

Install using Homebrew

We can use Homebrew to install Docker on macOS.

Homebrew's Cask already supports Docker for Mac, so you can easily use Homebrew Cask to install:

$　brew　install　--cask　--appdir=/Applications　docker
==>　Creating　Caskroom　at　/usr/local/Caskroom
==>　We'll　set　permissions　properly　so　we　won't　need　sudo　in　the　future
Password:　　　　　　　　　　#　Enter　macOS　password
==>　Satisfying　dependencies
==>　Downloading　https://download.docker.com/mac/stable/21090/Docker.dmg
########################################################################　100.0%
==>　Verifying　checksum　for　Cask　docker
==>　Installing　Cask　docker
==>　Moving　App　'Docker.app'　to　'/Applications/Docker.app'.
🍺　　docker　was　successfully　installed!

After loading the Docker app, click Next. You may be prompted for your macOS login password, just enter it. After that, a Docker running prompt window will pop up, and there will also be a small whale icon in the status bar (()).

Manual download and installation

If you need to download manually, please click the following link to download Stable or Edge version of Docker for Mac.

Like other software on macOS, the installation is also very simple, double-click the downloaded .dmg file, then drag the whale icon to the Application folder.

Find the Docker icon in the app and click to run. You may be prompted for the macOS login password, just enter it.

Clicking the whale icon in the top status bar will pop up the operation menu.

Clicking the icon for the first time may display the installation successful interface, click "Got it!" to close this window.

After starting the terminal, you can check the Docker version installed with the command.

$ docker　--version
Docker version　17.09.1-ce, build　19e2cf6

Image Acceleration

Due to domestic network issues, the subsequent pulling of Docker images is very slow, and we can configure an accelerator to solve this problem. I use the NetEase mirror address: http://hub-mirror.c.163.com.

Click the Docker for mac application icon in the taskbar -> Preferences... -> Daemon -> Registry mirrors. Fill in the accelerator address in the list. After the modification is complete, click the Apply & Restart button, Docker will restart and apply the configured image address.

After that, we can use the 'docker info' command to check if the configuration is successful.

$ docker info
