卸载旧版本 Docker
sudo apt-get remove docker docker-engine docker.io containerd runc
配置软件源
更新软件源并安装依赖包
sudo apt-get update
sudo apt-get install \
apt-transport-https \
ca-certificates \
curl \
gnupg-agent \
software-properties-common
添加 Docker 官方软件包密钥
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
验证密钥是否安装成功
toor@toor:~/Desktop$ 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]
添加软件源
查询当前系统所基于的 Debian 版本,得到以下回显
toor@toor:~/Desktop$ cat /proc/version
Linux version 5.8.0-63-generic (buildd@lgw01-amd64-035) (gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0, GNU ld (GNU Binutils for Ubuntu) 2.34)
通过查询得知 Debian 9 对应的代号为 stretch ,之后执行以下命令写入 docker 软件源
echo 'deb https://download.docker.com/linux/debian stretch stable' | sudo tee -a /etc/apt/sources.list.d/docker.list
正常写入回显
toor@toor:~/Desktop$ echo 'deb https://download.docker.com/linux/debian stretch stable' | sudo tee -a /etc/apt/sources.list.d/docker.list
[sudo] password for toor:
deb https://download.docker.com/linux/debian stretch stable
安装 Docker
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io -y
安装之后可以配置一下 Docker 镜像加速
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["http://hub-mirror.c.163.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
配置好后执行以下命令进行测试
sudo docker run hello-world
得到以下回显显示为正常
toor@toor:~/Desktop$ sudo docker run hello-world
[sudo] password for toor:
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world

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

卸载软件
sudo apt-get purge docker-ce docker-ce-cli containerd.io
删除镜像、容器、自定义配置等文件
sudo rm -rf /var/lib/docker
安装 Docker-Compose
sudo curl -L "https://github.com/docker/compose/releases/download/1.25.5/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose -v
回显版本号则安装成功
