# Full Infrastructure Template\n\nThis is a comprehensive infrastructure template with multiple server types and advanced configuration examples.\n\n## What's Included\n\n- **Web servers** - 2 frontend web servers\n- **Database server** - Backend database with private networking\n- **Kubernetes control plane** - Control plane node\n- **Kubernetes workers** - 2 worker nodes\n- **Advanced settings** - SSH config, monitoring, backup options\n- **Comprehensive examples** - Multiple server roles and configurations\n\n## Server Inventory\n\n| Hostname | Role | Network | Purpose |\n| ---------- | ------ | --------- | --------- |\n| web-01, web-02 | Web | Public + Private | Frontend application servers |\n| db-01 | Database | Private only | Backend database |\n| k8s-control-01 | K8s Control | Public + Private | Kubernetes control plane |\n| k8s-worker-01, k8s-worker-02 | K8s Worker | Public + Private | Kubernetes compute nodes |\n\n## Quick Start\n\n### 1. Load Required Modules\n\n```\ncd infra/<your-infra-name>\n\n# Load provider\nprovisioning mod load providers . upcloud\n\n# Load taskservs\nprovisioning mod load taskservs . kubernetes containerd cilium\n\n# Load cluster configurations (optional)\nprovisioning mod load clusters . buildkit\n```\n\n### 2. Customize Configuration\n\nEdit `servers.k`:\n\n**Provider-specific settings:**\n\n```\n# Uncomment and adjust for your provider\nplan = "2xCPU-4GB" # Server size\nstorage_size = 50 # Disk size in GB\n```\n\n**Task services:**\n\n```\n# Uncomment after loading modules\ntaskservs = [\n { name = "kubernetes", profile = "control-plane" }\n { name = "containerd", profile = "default" }\n { name = "cilium", profile = "default" }\n]\n```\n\n**Select servers to deploy:**\n\n```\n# Choose which server groups to deploy\nall_servers = web_servers + db_servers # Web + DB only\n# OR\nall_servers = k8s_control + k8s_workers # Kubernetes cluster only\n# OR\nall_servers = web_servers + db_servers + k8s_control + k8s_workers # Everything\n```\n\n### 3. Deploy\n\n```\n# Test configuration\nkcl run servers.k\n\n# Dry-run deployment (recommended)\nprovisioning s create --infra <name> --check\n\n# Deploy selected servers\nprovisioning s create --infra <name>\n\n# Or deploy specific server groups\nprovisioning s create --infra <name> --select web\n```\n\n## Architecture Examples\n\n### Web Application Stack\n\nDeploy web servers + database:\n\n```\nall_servers = web_servers + db_servers\n```\n\n### Kubernetes Cluster\n\nDeploy control plane + workers:\n\n```\nall_servers = k8s_control + k8s_workers\n```\n\n### Complete Infrastructure\n\nDeploy everything:\n\n```\nall_servers = web_servers + db_servers + k8s_control + k8s_workers\n```\n\n## Advanced Configuration\n\n### Network Segmentation\n\n- **Public servers**: web-01, web-02 (public + private networks)\n- **Private servers**: db-01 (private network only)\n- **Hybrid**: k8s nodes (public for API access, private for pod networking)\n\n### Monitoring\n\nMonitoring is pre-configured in settings:\n\n```\nmonitoring = {\n enabled = True\n metrics_port = 9100\n log_aggregation = True\n}\n```\n\n### SSH Configuration\n\nAdvanced SSH settings are included:\n\n```\nssh_config = {\n connect_timeout = 30\n retry_attempts = 3\n compression = True\n}\n```\n\n## Next Steps\n\n1. **Customize server specs** - Adjust CPU, memory, storage\n2. **Configure networking** - Set up firewall rules, load balancers\n3. **Add taskservs** - Uncomment and configure task services\n4. **Set up clusters** - Deploy Kubernetes or container clusters\n5. **Configure monitoring** - Set up metrics and logging\n6. **Implement backup** - Configure backup policies\n\n## Template Characteristics\n\n- **Complexity**: High\n- **Servers**: 6 examples (web, database, k8s)\n- **Pre-configured modules**: Examples for all major components\n- **Best for**: Production deployments, complex architectures, learning advanced patterns
