Every timeout stack trace pointed at ssl_gen_statem.call/2 — the OTP 27 SSL gen_statem hanging during recv. PG is on private network (10.0.15.20) and SSL verify was already disabled (verify_none), providing no security benefit while adding CPU overhead and the gen_statem layer that caused all connection timeouts. Removed DATABASE_SSL and DATABASE_SSL_VERIFY env vars from both the init container and main container. Also disabled SSL on the PG server (ssl=off in postgresql.conf, hostssl→host in pg_hba.conf).

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 imagestowerops-secrets- Application secrets (RELEASE_COOKIE, SECRET_KEY_BASE)towerops-db- Database connection credentialstowerops-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
