refactor: remove Valkey from K8s, move to Proxmox hosts
Removing all Valkey (Redis) resources from Kubernetes due to instability
caused by Flannel CNI networking issues. Redis will now run on Proxmox
hosts for better stability and performance.

Changes:
- Delete Valkey StatefulSet (master + 2 replicas)
- Delete Valkey Sentinel StatefulSet (3 instances)
- Delete Valkey services (headless and sentinel)
- Delete Valkey ConfigMap
- Remove Valkey resources from kustomization.yaml
- Update deployment to use towerops-redis secret for connection

Next Steps:
- Set up Redis Sentinel on 3 Proxmox hosts/LXC containers
- Create towerops-redis secret with REDIS_HOST and REDIS_PORT
- Test failover and application connectivity

Benefits:
- Not affected by K8s networking issues (Flannel failures)
- More stable (no restarts from node issues)
- Better performance (no K8s overhead)
- Independent lifecycle from K8s cluster

Kubernetes Deployment

Secrets Management

Secrets are managed directly in the cluster and must be created before deploying the application.

Required secrets in the towerops namespace:

  • gitlab-registry - Docker registry credentials for pulling images
  • towerops-secrets - Application secrets (RELEASE_COOKIE, SECRET_KEY_BASE)
  • towerops-db - Database connection credentials
  • towerops-aws - AWS credentials (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_REGION)

For local development, the project root .envrc is used by direnv.

Deployment Timestamp

The application footer displays the deployment timestamp to track when the current version was deployed. This is automatically set by GitLab CI during deployment:

# GitLab CI sets this during deploy
- kubectl set env deployment/towerops DEPLOY_TIMESTAMP=$(date -u +"%Y-%m-%dT%H:%M:%SZ") -n towerops

All pods in the deployment share the same timestamp (when the deployment was initiated), regardless of when individual pods were created. This is displayed in the footer as "Last deployed X ago · YYYY-MM-DD HH:MM:SS UTC".

For manual deployments without GitLab CI, set the timestamp:

kubectl set env deployment/towerops DEPLOY_TIMESTAMP=$(date -u +"%Y-%m-%dT%H:%M:%SZ") -n towerops

Deploying

Apply all resources using kustomize:

kubectl apply -k k8s/

Or individually:

kubectl apply -f k8s/namespace.yaml
kubectl apply -f k8s/secret.yaml
kubectl apply -f k8s/deployment.yaml
kubectl apply -f k8s/service.yaml
kubectl apply -f k8s/service-headless.yaml
kubectl apply -f k8s/certificate.yaml
kubectl apply -f k8s/ingressroute.yaml
