Helm is a package manager for Kubernetes, which simplifies the process of deploying and managing applications on a Kubernetes cluster. It allows users to define, install, and upgrade even the most complex Kubernetes applications using a simple command-line interface. Helm uses a templating system to create reusable application configurations, known as charts. Charts are collections of files that describe a related set of Kubernetes resources. With Helm, developers can easily share and distribute these charts, making it easier to manage applications across different environments. This streamlines the deployment process and enhances collaboration among teams working with Kubernetes.
