A production-ready, ultra-performance LiveKit deployment on Kubernetes, optimized for 1000+ concurrent participants with low latency. The deployment uses GitOps via ArgoCD and includes comprehensive monitoring and scaling capabilities.
- OpenStack Kubernetes Cluster: Auto-scaling cluster with 3 master nodes and 3-10 worker nodes
- Networking: Private network (192.168.64.0/24) with Calico CNI
- Storage: Cinder volumes (100GB per node)
- Load Balancing: Master node load balancer with floating IP (54.38.149.147:6443)

Important: The following DNS entries must be manually created before deployment:
- RTMP Ingress:
ingress.livekit-demo.cloudportal.appβ LoadBalancer IP - TURN Server:
turn.livekit-demo.cloudportal.appβ LoadBalancer IP
These services use LoadBalancer type services and require direct DNS entries for proper operation.

~/livekit-demo-rc.shbefore Terraform operations - The infrastructure uses OpenStack Container Infrastructure API
- ArgoCD manages applications through the core-services project
- Auto-scaling responds to cluster load automatically
- System is optimized for 1000+ concurrent participants with sub-100ms latency
The core-services application uses the app-of-apps pattern to manage all platform services:
Application Details:
- Name: core-services
- Project: core-services
- Repository: https://github.com/QumulusTechnology/livekit-demo.git
- Path: chart/
- Sync Policy: Automated with prune and self-heal enabled
The deployment uses sync waves to ensure proper dependency ordering:
Wave -1: CRDs and Operators
external-secrets- External Secrets Operator for managing secretsprometheus-operator-crds- Prometheus CRDs for monitoringcnpg-system- CloudNativePG operator for PostgreSQL
Wave 0: Core Infrastructure
cert-manager- TLS certificate managementingress-nginx- Ingress controller for routing
Wave 1: Data Layer
redis- Redis cluster for distributed stateminio-operator- MinIO operator for object storageharbor- Container registryloki- Log aggregationmimir- Metrics storage
Wave 2: Application Layer
livekit- LiveKit serverminio-tenant- MinIO storage tenantgrafana- Monitoring dashboardgrafana-agent- Metrics/logs collectortrivoh-api- Trivoh API service
Wave 3: Dependent Services
livekit-egress- LiveKit recording/streaming (depends on LiveKit server)livekit-ingress- RTMP/WHIP ingress (depends on LiveKit server + Redis)livekit-manifests- Additional LiveKit configurationsharbor-container-webhook- Harbor webhook configurations
Wave 4: Client Applications
meet-client- Video conferencing frontendtrivoh- Trivoh frontend application
This wave structure ensures:
- CRDs are installed before resources that use them
- Infrastructure components deploy before applications
- Dependencies are respected (e.g., LiveKit deploys before its ingress/egress)
- Client applications deploy last when all services are ready

- ArgoCD will automatically detect and deploy the new service
This infrastructure follows GitOps principles:
- All changes made through Git commits
- ArgoCD automatically synchronizes changes
- Infrastructure managed via Terraform
- Applications managed via Helm charts and ArgoCD
