Docker 的旧版本被称为 docker，docker.io 或 docker-engine 。如果已安装，请卸载它们：
$ sudo apt-get remove docker docker-engine docker.io containerd runc
当前称为 Docker Engine-Community 软件包 docker-ce 。
安装 Docker Engine-Community，以下介绍两种方式。
在新主机上首次安装 Docker Engine-Community 之前，需要设置 Docker 仓库。之后，您可以从仓库安装和更新 Docker 。
更新 apt 包索引
$ sudo apt-get update
安装 apt 依赖包，用于通过HTTPS来获取仓库:
$ sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common
添加 Docker 的官方 GPG 密钥：
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88 通过搜索指纹的后8个字符，验证您现在是否拥有带有指纹的密钥
$ sudo apt-key fingerprint 0EBFCD88 pub rsa4096 2017-02-22 [SCEA] 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88 uid [ unknown] Docker Release (CE deb) <docker@docker.com> sub rsa4096 2017-02-22 [S]
使用以下指令设置稳定版仓库
$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
更新 apt 包索引。
$ sudo apt-get update
安装最新版本的 Docker Engine-Community 和 containerd ，或者转到下一步安装特定版本：
$ sudo apt-get install docker-ce docker-ce-cli containerd.io
要安装特定版本的 Docker Engine-Community，请在仓库中列出可用版本，然后选择一种安装。列出您的仓库中可用的版本：
$ apt-cache madison docker-ce docker-ce | 5:18.09.1~3-0~ubuntu-xenial | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages docker-ce | 5:18.09.0~3-0~ubuntu-xenial | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages docker-ce | 18.06.1~ce~3-0~ubuntu | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages docker-ce | 18.06.0~ce~3-0~ubuntu | https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages ...
使用第二列中的版本字符串安装特定版本，例如 5:18.09.1~3-0~ubuntu-xenial。
$ sudo apt-get install docker-ce=<VERSION_STRING> docker-ce-cli=<VERSION_STRING> containerd.io
测试 Docker 是否安装成功，输入以下指令，打印出以下信息则安装成功:
$ sudo docker run hello-world Unable to find image ‘hello-world:latest‘ locally latest: Pulling from library/hello-world 1b930d010525: Pull complete Digest: sha256:c3b4ada4687bbaa170745b3e4dd8ac3f194ca95b2d0518b417fb47e5879d9b5f Status: Downloaded newer image for hello-world:latest Hello from Docker! 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/
对于使用 systemd 的系统，请在 /etc/docker/daemon.json 中写入如下内容（如果文件不存在请新建该文件）
{ "registry-mirrors": [ "http://hub-mirror.c.163.com" ] }
重新启动服务生效
sudo systemctl daemon-reload
sudo systemctl restart docker
$ docker info ...... Registry Mirrors: http://hub-mirror.c.163.com Live Restore Enabled: false
