debian国内安装docker

先升级apt和安装依赖包

apt update
apt upgrade
apt install curl vim wget gnupg dpkg apt-transport-https lsb-release ca-certificates

添加存储库的GPG密钥（阿里云）

curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

添加docker的apt源（阿里云）

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

更新apt后就可以安装docker

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

添加国内hub镜像，在/etc/docker/daemon.json文件中（没有就新建）添加下面国内镜像地址

{"registry-mirrors": ["https://do.nark.eu.org","https://dc.j8.work","https://docker.m.daocloud.io","https://dockerproxy.com","https://docker.mirrors.ustc.edu.cn","https://docker.nju.edu.cn"]
}
