What is Helm?
- The package manager for kubernetes, Helm is the best way to find, share, and use software built for kubernetes.
Helm helps you manage Kubernetes applications — Helm Charts helps you define, install, and upgrade even the most complex Kubernetes application.
Charts are easy to create, version, share, and publish — so start using Helm and stop the copy-and-paste madness.
The latest version of Helm is maintained by the CNCF - in collaboration with Microsoft, Google, Bitnami and the Helm contributor community.
Why use Helm?
kubernetes发布一个生产级别的微服务应用需要包含的内容；当环境中的微服务越来越多，单纯通过手工的方式去管理将会非常混乱和负载。这时候Helm就应该登场了。
