# MacOS Docker Installation ## Installing via Homebrew On macOS, we can use Homebrew to install Docker. Homebrew's Cask already supports Docker for Mac, making it very convenient to install using Homebrew Cask: $ 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 to enter your macOS login password. After that, a Docker running notification window will appear, and a small whale icon will be visible in the status bar ((#)). * * * ## Manual Download and Installation If you need to download manually, please click the following link to download (https://docs.docker.com/docker-for-mac/install/). !(#) Like other macOS software, the installation is very simple. Double-click the downloaded .dmg file, then drag the whale icon to the Application folder. !(#) Find the Docker icon in your applications and click to run it. You may be prompted to enter your macOS login password. !(#) Clicking the whale icon in the top status bar will bring up the operations menu. !(#) !(#) The first time you click the icon, you may see this installation success screen. Click "Got it!" to close this window. !(#) After starting the terminal, you can check the installed Docker version with the command. $ docker --version Docker version 17.09.1-ce, build 19e2cf6 ## Image Acceleration Due to domestic network issues, pulling Docker images later can be very slow. We may need to configure an accelerator to solve this. I am using NetEase's 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 making the changes, click the Apply & Restart button, and Docker will restart and apply the configured mirror address. !(#) After that, we can use `docker info` to check if the configuration was successful. $ docker info ...Registry Mirrors: http://hub-mirror.c.163.comLive Restore Enabled: false
