Helm is a tool that makes it easier to install and manage applications on Kubernetes. If Kubernetes is the system where your apps run, Helm is the package manager that helps you find, install, and update those apps without manually writing or tweaking all the underlying configuration files. Think of it like Homebrew or apt, but for Kubernetes. At a high level, the tool has two parts. The client piece runs on your laptop or in your automated deployment pipeline. A second piece, called Tiller, runs inside your Kubernetes cluster and handles the actual work of installing and managing the apps. You use the client to tell Tiller what to do, and Tiller executes those instructions in your cluster. The packages Helm manages are called "charts." A chart is just a bundle of pre-configured files that describe how a piece of software should run on Kubernetes. You can download charts from remote repositories, much like you download apps from an app store, or you can create your own charts to share applications you have built. This makes it possible to create reproducible installations, so the same app deploys the same way every time. This project would be useful for teams running software on Kubernetes who want a reliable way to manage their deployments. For example, if your team needs to install a database, a monitoring tool, or your own application across different environments like testing and production, you could package it as a chart and use Helm to deploy it consistently each time. It also helps track different versions of what you have installed, so you can upgrade or roll back when needed. One notable design choice is the two-part architecture with a server component running inside the cluster. This means Tiller has direct access to manage things in your Kubernetes environment, which enables the release-tracking and rollback features, but it also requires running an additional service inside your infrastructure.
