Kubernetes Cluster Creator

Construct Cluster by Infrastructure as Code (IaC).

前置准备

1. 安装 go-task

   参考：go-task官方安装指南

2. 安装 ansible

   pip3 install ansible

   注意根据安装指南将执行路径加入环境变量，使得命令行可以直接识别 ansible 命令，如： export Path=$Path:/home/ubuntu/.local/bin。

3. 安装 kubernetes 库

   pip3 install kubernetes

4. 安装helm

   参考：Helm 官方安装指南 Ubuntu 可使用 snap 安装：

   sudo snap install helm --classic

5. 安装 kubectl

   参考：Kubectl 官方安装指南 Ubuntu 可使用 snap 安装：

   sudo snap install kubectl --classic

6. 安装 vela-cli

   参考：KubeVela官方文档

   curl -fsSl https://kubevela.io/script/install.sh | bash
