安装

  卸载旧版本(如未安装过直接跳过此步骤）

sudo apt-get remove docker docker-engine docker.io containerd runc

  设置仓库

• 更新软件源

 sudo apt-get update

• 安装依赖包

sudo apt-get install \\
    ca-certificates \\
    curl \\
    gnupg \\
    lsb-release

• 添加 Docker 的官方 GPG 密钥：返回OK证明成功

 curl -fsSL https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu/gpg | sudo apt-key add -

• 设置稳定版仓库

sudo add-apt-repository \\
   "deb [arch=amd64] https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu/ \\
  $(lsb_release -cs) \\
  stable"

   安装 Docker Engine-Community 

• 更新软件源

 sudo apt-get update

• 安装最新版本的 Docker Engine-Community 和 containerd

sudo apt-get install docker-ce docker-ce-cli containerd.io

• 验证安装是否成功： sudo docker run hello-world

执行：sudo docker run hello-world

返回如下内容说明安装成功！

Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
2db29710123e: Pull complete 
Digest: sha256:2498fce14358aa50ead0cc6c19990fc6ff866ce72aeb5546e1d59caac3d0d60f
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

卸载

• 删除docker及其安装时自动安装的所有包

sudo apt-get autoremove docker docker-ce docker-engine  docker.io  containerd runc

• 查看docker其他没有卸载软件

dpkg -l | grep docker
dpkg -l |grep ^rc|awk 'print $2' |sudo xargs dpkg -P 

• 卸载没有删除的docker相关插件(根据上一个命令返回的值)

sudo apt-get autoremove docker-ce-*  #后面要删除的是根据上个命令返回的值

• 删除docker的相关配置&目录

 sudo rm -rf /etc/systemd/system/docker.service.d
 sudo rm -rf /var/lib/docker

•  验证删除是否成功，找不docker命令说明卸载docker成功

docker --version

其他

• 自动安装：curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
