redis

Redis on Kubernetes

Resources are defined in k8s/redis.yaml (PVC, Deployment, Service).

What gets created

  1. PersistentVolumeClaim wilforlan-agent-play-redis-data — 1Gi, ReadWriteOnce. AOF data under /data.
  2. Deployment wilforlan-agent-play-redis — one replica, Recreate strategy, image public.ecr.aws/docker/library/redis:7.2-alpine, redis-server --appendonly yes, resource requests/limits, exec probes (redis-cli ping), fsGroup: 999 for volume permissions with the official image user.
  3. Service wilforlan-agent-play-redis — ClusterIP port 6379.

Web UI connection

The web UI uses REDIS_URL=redis://wilforlan-agent-play-redis:6379 in namespace wilforlan-agent-play. An initContainer on the web UI pod waits until Redis accepts TCP connections before starting the app.

Operations

  • Replicas: Sample is single-instance Redis; use a managed offering or Redis Sentinel/Cluster for HA if required.
  • Auth: Not configured; add Redis --requirepass and a Secret, then extend REDIS_URL.

Application behavior: Redis / repository.
