Debian安装Docker

卸载冲突的软件包

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

更新系统并安装依赖

apt update
apt install -y ca-certificates curl gnupg

添加 Docker 的官方 GPG 密钥

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

添加阿里云 Docker CE 源

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

安装 Docker

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

验证安装

docker run hello-world

（可选）配置 Docker 镜像加速器
