feat: add Valkey as k8s sidecar for Redis compatibility 
- Add Valkey 8.0 alpine container as sidecar in k8s deployment
- Configure with appropriate security context (non-root, no privilege escalation)
- Add resource limits (256Mi memory, 200m CPU) and requests (128Mi, 50m)
- Add health probes using valkey-cli ping command
- Configure Redis connection via REDIS_HOST and REDIS_PORT environment variables
- Add Redis config to runtime.exs, dev.exs, and test.exs
- Valkey runs on localhost:6379 within the same pod as Phoenix app

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
