Kapp
Kapp is a command-line tool for deploying and managing Kubernetes applications by grouping Kubernetes resources into logical units called applications. It provides a declarative approach to application lifecycle management, enabling idempotent deployments, versioning, and diffing of changes. It is part of the Carvel suite of tools and is designed to simplify Kubernetes operations for developers and operators.
Developers should learn Kapp when working with Kubernetes to streamline application deployments, especially in complex environments with multiple resources. It is particularly useful for ensuring consistent and repeatable deployments, managing application versions, and visualizing changes before applying them. Use cases include CI/CD pipelines, multi-environment deployments (e.g., staging, production), and teams needing better control over Kubernetes resource management.
