Modern software deployment involves managing configurations for applications, infrastructure, and services, especially in cloud-native environments. Kubernetes, a prominent orchestrator, presents its own set of configuration management challenges. This is where kpt— a toolkit for Kubernetes-native packaging— steps in. But what exactly is kpt, and why should we care? Let's dive deep.
