kustomize
Kustomize is a command line tool for customizing Kubernetes resources. It allows you to manage and customize deployment configurations programmatically. Kustomize follows a declarative approach, enabling you to define desired state instead of writing imperative scripts. It is part of the official Kubernetes project and is widely used within the Kubernetes community. With Kustomize, you can perform overlays on a base configuration to create multiple variants customized for different environments or purposes. It supports different customization techniques, including adding, modifying, or removing fields from YAML files. Kustomize leverages a patching mechanism to apply changes incrementally without modifying the base resources directly. You can organize customization configurations into multiple layers, making it easy to manage complex deployments. It integrates well with other Kubernetes components like kubectl and kubeval, simplifying the workflow for managing applications on Kubernetes. Kustomize is highly extensible and allows you to write custom transformers and generators to enhance its functionality.
