# =============================================================================
# AI Software Factory — Redis 7 (Deployment + Service)
#
# Used for caching, BullMQ job queues and realtime presence/pubsub.
# Single replica for simplicity. For production, prefer MANAGED ElastiCache /
# Memorystore / AOF-backed replicas — a lost Redis queue means lost jobs.
#
# PVC NOTE:
#   Redis persistence (AOF) is enabled below with a ReadWriteOnce PVC.
#   If you switch to managed Redis, delete the volume + volumeMount entirely
#   and point REDIS_URL at the managed endpoint via the factory-config
#   ConfigMap / factory-secrets Secret.
