如何在Debian操作系统上安装Doker

本章教程，主要介绍如何在Debian 11 系统上安装Docker。主要使用一键安装Docker脚本和一键卸载脚本来完成。

一、安装Docker

当然，你也可以用下面这个在线脚本进行安装。

curl -sSL https://file.ewbang.com/docker/debian/install_docker.sh -o install_docker.sh && bash install_docker.sh

二、卸载Docker

#!/bin/bash# 停止 Docker 服务
echo "Stopping Docker service..."
sudo systemctl stop docker# 卸载 Docker 相关软件包
echo "Removing Docker packages..."
sudo apt-get purge -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin# 删除 Docker 数据
echo "Deleting Docker data..."
sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd# 删除 Docker 配置文件
echo "Deleting Docker configuration..."
sudo rm -rf /etc/docker# 自动清理不需要的软件包
echo "Cleaning up..."
sudo apt-get autoremove -y
sudo apt-get updateecho "Docker uninstalled successfully."

同样，下面也提供在线脚本。

curl -sSL https://file.ewbang.com/docker/debian/uninstall_docker.sh -o uninstall_docker.sh && bash uninstall_docker.sh
