最近几年来，地理信息系统无论是在理论上还是应用上都处在一个飞速发展的阶段。 GIS被应用于多个领域的建模和决策支持，如城市管理、区划、环境整治等等，地理信息成为信息时代重要的组成部分之一； “数字地球”概念的提出，更进一步推动了作为其技术支撑的GIS的发展。 与此同时，一些学者致力于相关的理论研究，如空间感知、空间数据误差、空间关系的形式化等等。 这恰好说明了地理信息系统作为应用技术和学科的两个方面，并且这两个方面构成了相互促进的发展过程。
2.7.1. Install using Homebrew ¶
MacOS We can use Homebrew to install Docker.
Homebrew’s Cask already supports Docker for Mac, so it’s easy 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: # 输入 macOS 密码 ==> 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 Docker app, click Next, you may be asked for your macOS login password, you can enter it. After that, a prompt window for Docker to run will pop up, and there will also be a little whale icon on the status bar ( 
).
2.7.2. Download and install manually ¶
If you need to download manually, please click the link below to download Install Docker Desktop on Mac .
Like other macOS software, installation is easy, double-click the downloaded .dmg file, and then drag the whale icon to the Application folder.
Find the Docker icon in the application and click run. You may ask for the login password of macOS and enter it.
Clicking the whale icon in the top status bar will bring up the action menu.
The first time you click on the icon, you may see the successful installation interface, click “Got it!” You can close this window.
After starting the terminal, you can check the installed version of Docker with the command.
$ docker --version Docker version 17.09.1-ce, build 19e2cf6 2.7.3. Mirror acceleration ¶
In view of the domestic network problems, it is very slow to pull the Docker image later. We can configure an accelerator to solve it. I use NetEase’s image address: http://hub-mirror.c.163.com .
Click the Docker for mac App icon-> Perferences… in the taskbar After the modification is completed, click the Apply & Restart button, and Docker will restart and apply the configured image address.
We can then use docker info to see if the configuration is successful.
$ docker info ... Registry Mirrors: http://hub-mirror.c.163.com Live Restore Enabled: false
