# Example: Complete Provisioning Platform - Enterprise Deployment
#
# This example demonstrates deploying all three platform services together
# in enterprise mode with full integration, security, and observability.
#
# Deployment Architecture:
# - 3x Orchestrator replicas (load balanced)
# - 1x Control Center (with PostgreSQL)
# - 1x MCP Server (for AI/LLM integration)
# - SurrealDB cluster for workflow storage
# - Comprehensive monitoring (Prometheus, Grafana, Loki)
# - Full RBAC, audit logging, and compliance
#
# Usage:
#   # Generate all three configs
#   nickel eval --format toml orchestrator.ncl > orchestrator.enterprise.toml
#   nickel eval --format toml control-center.ncl > control-center.enterprise.toml
#   nickel eval --format toml mcp-server.ncl > mcp-server.enterprise.toml
#
#   # Deploy to Kubernetes
#   kubectl apply -f provisioning/platform/infrastructure/kubernetes/namespace.yaml
#   kubectl apply -f provisioning/platform/infrastructure/kubernetes/resource-quota.yaml
#   kubectl apply -f provisioning/platform/infrastructure/kubernetes/rbac.yaml
#   kubectl apply -f provisioning/platform/infrastructure/kubernetes/*.deployment.yaml
