Pod enricher

The pod enricher is deprecated as of the Stackable Data Platform 24.11, and will be removed in the next release. For more information, see issue #292.

The Stackable Commons Operator automatically adds commonly used information to Pod objects, which would otherwise have to be inferred by traversing the Kubernetes object graph.

Usage

To enable the pod enricher for a Pod, set the label enrichment.stackable.tech/enabled to true.

Which information is added to the Pod?

Annotation: enrichment.stackable.tech/node-address

The hostname or IP address of the Node that the Pod is scheduled to run on. Compared to Pod.status.nodeIP, this can also (but doesn’t have to) be a hostname, and prefers externally routable addresses.

This is intended to be used for components that need to register an accessible address (such as Kafka brokers, or HDFS DataNodes).
