一. 安装Docker
第一步：更新系统软件包索引
sudo apt update第二步：安装必要依赖包
sudo apt install apt-transport-https ca-certificates curl gnupg lsb-release software-properties-common第三步：添加Docker官方GPG密钥
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg第四步：添加Docker的APT源
echo \
"deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null第五步：更新软件包列表并安装Docker
sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io docker-compose-plugin
二. K8S
考虑网络问题，这里通过阿里云的Kubernetes软件源安装，可以这样做：
首先，导入阿里云的apt-key：
curl -s https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | sudo apt-key add -接着，添加阿里云的Kubernetes APT源到系统中：
cat <<EOF | sudo tee /etc/apt/sources.list.d/kubernetes.list
deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main
EOF最后，更新软件包列表并安装Kubernetes组件：
sudo apt update
sudo apt install -y kubelet kubeadm kubectl
