1、安装必要的依赖包
apt-get update
apt-get install -y apt-transport-https ca-certificates curl gnupg lsb-release
2、创建目录并正确添加Docker的GPG密钥
mkdir -p /etc/apt/keyrings
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/debian/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
3、设置正确的文件权限
chmod a+r /etc/apt/keyrings/docker.gpg
4、设置Docker仓库
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
5、更新apt包索引
apt-get update
6、准备Docker数据目录
创建Docker数据目录
mkdir -p /data/docker
创建Docker配置目录
mkdir -p /etc/docker
配置Docker数据目录和加速
cat > /etc/docker/daemon.json <<EOF
{
"data-root": "/data/docker"
"registry-mirrors" : [
"https://docker-cf.registry.cyou",
"https://dockercf.jsdelivr.fyi",
"https://docker.jsdelivr.fyi",
"https://dockertest.jsdelivr.fyi",
"https://mirror.iscas.ac.cn",
"http://mirrors.ustc.edu.cn/",
"https://mirrors.tuna.tsinghua.edu.cn/",
"http://mirrors.sohu.com/"
],
"insecure-registries" : [
"registry.docker-cn.com",
"docker.mirrors.ustc.edu.cn"
],
"debug": true,
"experimental": false
}
EOF
7、安装Docker
apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
8、确保服务正常启动
systemctl enable docker
systemctl start docker
9、验证安装结果和数据目录
docker --version
docker info | grep "Docker Root Dir"
