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。
Docker Engine-Community supports the following Ubuntu versions:
Xenial 16.04 (LTS)
Bionic 18.04 (LTS)
Cosmic 18.10
Disco 19.04
Other newer versions…
Docker Engine-Community supports the x86x64 (or amd64) armhf,arm64,s390x (IBM Z) and ppc64le (IBM’s Power) architectures. The installation commands are as follows: You can also use the domestic daocloud one-click installation command: Older versions of Docker are called docker,docker.io or docker-engine. If installed, uninstall them: Currently known as the Docker Engine-Community package docker-ce. There are two ways to install Docker Engine-Community. Before installing Docker Engine-Community on the new host for the first time, you need to set up the Docker repository. You can then install and update Docker from the repository. Update the apt package index. Install the apt dependency package, which is used to obtain the repository through HTTPS: Add the official GPG key for Docker: 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88 verifies that you now have a key with a fingerprint by searching for the last 8 characters of the fingerprint. Use the following instructions to set up the stable version repository Update the apt package index. Install the latest version of Docker Engine-Community and containerd, or go to the next step to install a specific version: To install a specific version of Docker Engine-Community, list the available versions in the repository, and then select an installation. List the versions available in your warehouse: Install a specific version using the version string in the second column, for example, 5 0~ubuntu-xenial 18.09.1 version 3-version. To test whether Docker is installed successfully, enter the following instructions and print out the following information for successful installation: Docker in get.docker.com And test.docker.com Convenient scripts are provided on the for quick installation of edge versions and test versions of Docker Engine-Community. The source code for the script is in the docker-install repository. It is not recommended to use these scripts in a production environment, and you should be aware of the potential risks before using them: The script needs to run root or have sudo privileges. Therefore, you should carefully review and review the script before running it. These scripts try to detect Linux distributions and versions and configure the package management system for you. In addition, the script does not allow you to customize any installation parameters. From the perspective of Docker or the guidelines and standards of your own organization, this can lead to unsupported configurations. These scripts install all dependencies and recommendations of the package manager without confirmation. This may install a large number of packages, depending on the current configuration of the host. The script does not provide the option to specify which version of Docker to install, but instead installs the latest version released in the edge channel. If you have used other mechanisms to install Docker on the host, do not use convenient scripts. This example uses the get.docker.com The script on the install the latest version of Docker Engine-Community on Linux. To install the latest test version, use test.docker.com instead. In each of the following commands, replace each occurrence of get with test. If you want to use Docker as a non-root user, you should consider adding users to the docker group in a manner similar to the following: Delete the installation package: Delete images, containers, configuration files, etc.: 2.3.1. Use the official installation script to install automatically ¶
curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
curl -sSL https://get.daocloud.io/docker | sh
2.3.2. Manual installation ¶
Uninstall the old version ¶
$ sudo apt-get remove docker docker-engine docker.io containerd runc
Use the Docker repository for installation ¶

This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (amd64) 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID: https://hub.docker.com/ For more examples and ideas, visit: https://docs.docker.com/get-started/
