Pod Enricher

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

The pod enricher is only enabled for Pod objects that set the label enrichment.stackable.tech/enabled to true.

Node Address

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).
