The use time of this test is 2023/7/20, basically the latest version or the latest stable version.

       Front

        Helm is a package management tool for Kubernetes that simplifies the deployment and management of Kubernetes applications. Helm uses a packaging format called a "chart" to organize and describe a set of related Kubernetes resources.

        The structure of a chart is roughly as follows, and the notes annotate the role of the file (the test should have Chart.yaml, values.yaml (no dynamic assignment or even need), and the templates directory):

my-chart/
│
├── Chart.yaml        # Chart 的基本信息，如名称、版本、描述等，该文件必需
├── values.yaml       # Chart 的默认配置值，安装 Chart 时可提供一个自定义values.yaml 文件或--set参数覆盖这些默认值。
├── templates/        # k8s资源模板文件，这些模板文件用 Go 模板语言编写，可根据 values.yaml 中配置值动态生成最后k8s资源。
│   ├── deployment.yaml
│   ├── service.yaml
│   ├── ingress.yaml
│   └── ...
│
├── charts/           # 依赖的其他 Helm chart（可选），可用Helm依赖管理功能自动下载和安装依赖的chart。
├── .helmignore       # Helm 忽略文件列表（可选），类似于 .gitignore用于指定打包 Chart 时需忽略的文件和目录
└── README.md         # Chart 的说明文档（可选），通常包括安装方法、配置选项等

sudo lsof -i :80 -i :443  # 查看端口80和443是否被占用
