Pulumi Query for Kubernetes is a tool and SDK designed to simplify the process of querying live Kubernetes resources, allowing users to answer complex questions about their clusters without manually parsing multiple command outputs. It supports both batch and streaming query modes; batch queries generate fixed reports, while streaming queries monitor resources in real-time, triggering actions based on specific events. For instance, batch queries can determine the distinct MySQL versions running in a cluster, while streaming queries can alert users to deployment changes. The tool uses core primitives like "list" for batch queries and "watch" for streaming, with advanced operations possible through methods like "join" and "groupJoin." By offering these capabilities, Pulumi Query aims to enhance observability, facilitate automation, and improve governance and security within Kubernetes environments, potentially leading to easier cluster operations by reducing the need for manual scripting.
