Docker安装

官方参考文档：Install Docker Engine on Debian

设置存储库

1. 下载所需工具：

sudo apt update && sudo apt install ca-certificates curl gnupg lsb-release -y

2. 添加 Docker 官方密钥

sudo mkdir -p /etc/apt/keyrings && cd /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

3. 添加Docker存储库

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

4. 设置Docker密钥权限

sudo chmod a+r /etc/apt/keyrings/docker.gpg

安装 Docker 引擎

1. 更新Docker软件包索引

sudo apt-get update

2. 安装Docker最新软件包

sudo apt install docker-ce docker-ce-cli containerd.io docker-compose-plugin -y

3. Docker验证

sudo docker info		#查看Docker详细信息
sudo docker compose version	#查看Docker commpose版本

#输出信息
#sudo docker info
