Helm charts are essentially packages of pre-configured Kubernetes resources that help you define, install, and upgrade Kubernetes applications.

Helm charts act as templates or blueprints for Kubernetes applications. They contain all the necessary resource definitions (like Deployments, Services, ConfigMaps) organized in a specific structure, along with default values that can be customized during deployment. This templating system allows you to deploy complex applications with a single command while maintaining consistency across different environments.

To help you understand the concept better, think of Helm charts as being similar to package managers in other ecosystems (like Composer for PHP or npm for Node.js). Just as you would use a package.json file to define your Node.js application dependencies, a Helm chart defines all the Kubernetes resources needed for your application to run properly.
