## Redis Memory



Redis is deployed through the Bitnami Redis Helm chart dependency as an in-cluster service and is used by the AI agent for optional short-term session memory. The generated agent value is:



```bash

REDIS_URL=redis://<redis-service>:6379/0

```



This mirrors the Docker Compose Redis container port `6379`; the chart disables Redis auth and persistence by default to match the local cache/session-store behavior. The Compose host mapping `6385:6379` is not represented as a Kubernetes NodePort because Kubernetes NodePorts must normally be in the cluster NodePort range, commonly `30000-32767`.
