debian安装Docker Engine

1. debian默认不带sudo,所以先安装sudo,并且debian默认启动的是非root账户

   su - root
   

   apt install sudo

2. 卸载乱七八糟的

   for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do sudo apt-get remove $pkg; done
   

    

3. 更新apt包索引并安装包以允许apt通过 HTTPS 使用存储库

   sudo apt-get update
   sudo apt-get install ca-certificates curl gnupg
   

4. 添加 Docker 的官方 GPG 密钥：

   sudo install -m 0755 -d /etc/apt/keyrings
   curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
   sudo chmod a+r /etc/apt/keyrings/docker.gpg
   

5. 设置存储库

   echo \
     "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian \
     "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
     sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
   

6. 安装 Docker 引擎

   sudo apt-get update
   sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
   

    

7. 验证下

sudo docker run hello-world
