1.更新aptget

sudo apt-get update

sudo apt-get install \
    ca-certificates \
    curl \
    gnupg \
    lsb-release

3.添加密钥

curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

4.安装docker引擎

sudo apt-get install docker-ce docker-ce-cli containerd.io

5.设置阿里云镜像加速

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://nskp0wed.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

6。让Docker容器随宿主机的启动而自动启动

 sudo systemctl start docker
 sudo systemctl enable docker.service

运行sudo docker ps ,看见如下图就成功了
