Find the Docker icon from the application and click Run. You may be asked for your macOS login password, enter it.

Click the whale icon in the top status bar to pop up the operation menu.

#When you click the icon for the first time, you may see the installation success interface. Click "Got it!" to close this window.

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

$ docker --version

Image acceleration

In view of domestic network problems, subsequent pulling of Docker images is very slow. We may need to configure an accelerator to solve the problem. I am using the NetEase image address. : http://hub-mirror.c.163.com.

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

Afterwards we can check whether the configuration is successful through docker info.

$ docker info
...
Registry Mirrors:
 http://hub-mirror.c.163.com
