K8S案例解析

helm的官方网站： https://helm.sh/zh/

helm是一个包管理器，用于Kubernetes，它可以将Helm Chart安装到Kubernetes集群中。Helm Chart是一个可重复使用的软件包，包含所有必需的资源定义，如Deployment、Service、Ingress、Secret、ConfigMap等。

helm相对k8s来说就像 apt 对Ubuntu yum对CentOS一样。

安装直接看官方文档

这里把命令补全的方式： https://helm.sh/zh/docs/helm/helm_completion/

针对bash 环境

https://helm.sh/zh/docs/helm/helm_completion_bash/ 贴出来

为当前会话提供命令补全

source <(helm completion bash)

为每个新的会话加载命令补全 （其他系统看文档）

Linux： helm completion bash | sudo tee /etc/bash_completion.d/helm
