Redis

Redis provides caching, session management, pub/sub messaging, and rate limiting across MATIH services. It is deployed via the Bitnami Helm chart with Sentinel for high availability.

Configuration

# From matih-control-plane/values.yaml
redis:
  enabled: true
  auth:
    enabled: true
    existingSecret: matih-redis-credentials
  master:
    persistence:
      enabled: true
      size: 10Gi
    resources:
      requests: { cpu: 200m, memory: 256Mi }
      limits: { cpu: 1000m, memory: 1Gi }
  replica:
    replicaCount: 2
    persistence:
      enabled: true
      size: 10Gi
  sentinel:
    enabled: true
  metrics:
    enabled: true
    serviceMonitor:
      enabled: true

Service Connections

# Control plane
redis:
  host: "redis-master.matih-control-plane.svc.cluster.local"
  port: 6379
 
# Data plane
