[2026-02-19] No Redis Sentinel Support and Silent Health Check Failure

Issue

The auth-service lacked support for Redis Sentinel in its configuration, preventing high-availability deployments. Additionally, the health check mechanism was “silent,” meaning it wouldn’t properly report a degraded state if Redis was unreachable but the application was still running.

Impact

• Availability: Redis failover was not supported.
• Observability: Kubernetes probes could not detect Redis connection issues, leading to traffic being routed to “zombie” instances.

Resolution

• Integrated ioredis with Sentinel support.
• Updated HealthModule to explicitly check Redis connectivity.
• Added REDIS_SENTINEL_NODES and REDIS_SENTINEL_NAME environment variables.
