Per Q-SO-1 operator resolution 2026-05-11 PM, Redis SignalR backplane lands
in Phase A (was Phase C deferral). Treats Redis as a managed FC infrastructure
component, not a deferred scaling escalation.
Lands the minimal Phase A surface:
- Namespace fc-redis
- Single Redis 7-alpine pod with 1Gi Longhorn RWO PVC
- ConfigMap with AOF persistence (everysec), 256Mi maxmemory, allkeys-lru
- ClusterIP Service `redis.fc-redis.svc.cluster.local:6379` (in-cluster only)
- No AUTH Phase A (Phase B add via 1Password Connect rotation)
- No IngressRoute (backplane is server-to-server)
Consumers (Phase A IMPL across FC services) add:
services.AddSignalR().AddStackExchangeRedis(
"redis.fc-redis.svc.cluster.local:6379",
opts => opts.Configuration.ChannelPrefix =
StackExchange.Redis.RedisChannel.Literal("fc-opsconsole"));
Phase B/C follow-ons (not in this commit): Sentinel for HA, AUTH password
from 1Password, redis_exporter sidecar for Prometheus, network policies.
