Kustomize Course Overview

Kustomize is a standalone tool to customize Kubernetes configurations. It is part of the Kubernetes ecosystem, designed to address the need for managing application configurations through customization rather than configuration templating. Kustomize introduces a template-free way to customize application resources using a declarative approach with resource files. It allows users to create overlays for different environments, applying patches without altering the original resource YAML files. Industries use Kustomize to maintain a clear, auditable, and reproducible process when deploying to Kubernetes, enabling them to handle complex deployment scenarios consistently and efficiently while avoiding duplication of manifest files.
