What is a Kubernetes Manifest?

A Kubernetes manifest is a YAML or JSON file that defines the desired state of a Kubernetes resource, such as Pods, Deployments, Services, or ConfigMaps. It describes the configuration and behavior of these resources, allowing Kubernetes to manage them efficiently. Properly validated manifests are critical to avoid deployment errors and ensure smooth operations within your Kubernetes cluster.
