### What Terraform Will Manage
```hcl
# Infrastructure Components
- Proxmox VMs (all VMs defined as Terraform resources)
- Network bridges and VLANs
- Storage allocations
- VM snapshots and backups (scheduled)
- Cloud-init configurations
- DNS records (if using external DNS)
```
### Directory Structure
```

## ☸️ Component 4: Kubernetes (K3s)
### Purpose
Lightweight Kubernetes for container orchestration, replacing standalone VMs for certain workloads.
### Why K3s?
- **Lightweight**: 100MB binary vs 1GB+ for full K8s
- **Easy setup**: Single command installation
- **Low resource**: Runs on smaller VMs
- **Full K8s**: 100% Kubernetes API compatible
- **Built-in**: Traefik ingress, local storage
### Cluster Topology
```
┌─────────────────────────────────────────────────────────┐
│ K3s Cluster - ORION │
├─────────────────────────────────────────────────────────┤
│ │
│ Control Plane (VM 600) │
│ ┌───────────────────────────────────────────────────┐ │
│ │ - etcd (distributed key-value store) │ │
│ │ - kube-apiserver │ │
│ │ - kube-scheduler │ │
│ │ - kube-controller-manager │ │
│ │ - Traefik ingress controller │ │
│ └───────────────────────────────────────────────────┘ │
│ │
│ Worker Nodes (VMs 601-603) │
│ ┌───────────────────────────────────────────────────┐ │
│ │ Worker 1 (601): General workloads │ │
│ │ Worker 2 (602): Stateful apps (databases) │ │
│ │ Worker 3 (603): Monitoring stack │ │
│ └───────────────────────────────────────────────────┘ │
│ │
└─────────────────────────────────────────────────────────┘
```
### What Runs on K8s
**Instead of separate VMs, these run as Pods:**
1. **Backstage** (formerly VM 400)
```yaml
Deployment: backstage
Replicas: 2 (HA)
Resources: 2 CPU, 4GB RAM per pod
Service: LoadBalancer (192.168.100.40)
Storage: PVC 50GB
```
2. **Vapor API** (formerly VM 401)
```yaml
Deployment: vapor-api
Replicas: 3 (load balanced)
Resources: 1 CPU, 2GB RAM per pod
Service: ClusterIP (internal only)
```
3. **Monitoring Stack**
```yaml
- Prometheus (metrics)
- Grafana (visualization)
- AlertManager (alerting)
- Node exporters (DaemonSet on all nodes)
```
4. **Additional Services**
```yaml
- Redis (caching)
- PostgreSQL (database)
- RabbitMQ (message queue)
- MinIO (S3-compatible storage)
```
### Storage
**Longhorn** - Distributed block storage for K8s
- Replicated volumes across worker nodes
- Snapshots and backups
- Web UI for management
### Networking
**CNI**: Cilium (instead of Flannel)
- Better performance
- Network policies
- Service mesh capabilities
- Observability
### Deployment via Terraform + Ansible
```hcl
# Terraform creates K8s VMs
module "k8s_cluster" {
source = "./modules/k8s-cluster"
master_count = 1
worker_count = 3
master_cpu = 4
master_ram = 8192
worker_cpu = 4
worker_ram = 16384
}
```
```yaml
# Ansible installs K3s
- hosts: k8s_masters
roles:
- k3s-master
- hosts: k8s_workers
roles:
- k3s-worker
```
### Benefits
- ✅ **Higher density**: More services per VM
- ✅ **Auto-scaling**: HPA (Horizontal Pod Autoscaler)
- ✅ **Self-healing**: Automatic pod restarts
- ✅ **Rolling updates**: Zero-downtime deployments
- ✅ **Resource efficiency**: Better CPU/RAM utilization
---
## 🔀 Component 5: GoBGP (Programmable Routing)
### Purpose
Replace BIRD2 with GoBGP for API-driven, programmable BGP routing.
### Why GoBGP over BIRD2?
| Feature | BIRD2 | GoBGP |
|---------|-------|-------|
| **API** | Limited | Full gRPC/REST API |
| **Language** | C | Go (easier to extend) |
| **Configuration** | Text files | API + config file |
| **Monitoring** | birdc CLI | Prometheus metrics built-in |
| **Automation** | Manual | Programmatic |
| **Libraries** | None | Go client library |

description = "Telus Gateway 3 - Tertiary"
[neighbors.afi-safis]
[[neighbors.afi-safis.list]]
afi-safi-name = "ipv6-unicast"
```
### API Usage Examples
**Add a route programmatically:**
```go
package main
import (
"context"
api "github.com/osrg/gobgp/v3/api"
"google.golang.org/grpc"
)
func main() {
conn, _ := grpc.Dial("192.168.100.1:50051", grpc.WithInsecure())
defer conn.Close()
client := api.NewGobgpApiClient(conn)
// Announce a new prefix
nlri := &api.IPAddressPrefix{
PrefixLen: 48,
Prefix: "2602:F674::",
}
attrs := []*api.PathAttribute{
api.NewOriginAttribute(0),
api.NewNextHopAttribute("::"),
api.NewAsPathAttribute([]uint32{394955}),
}
path := &api.Path{
Nlri: api.NewAnyFromMessage(nlri),
Pattrs: attrs,
}
client.AddPath(context.Background(), &api.AddPathRequest{
Path: path,
})
}
```
**REST API (via wrapper):**
```bash
# Get all neighbors
curl http://192.168.100.1:8080/v1/neighbors
# Get specific neighbor
curl http://192.168.100.1:8080/v1/neighbors/2602:F674:0000::ffff
# Add route
curl -X POST http://192.168.100.1:8080/v1/routes \
-H "Content-Type: application/json" \
-d '{
"prefix": "2602:F674:5000::/64",
"nexthop": "2602:F674:1000::1"
}'
```
### Integration with AI Agent
```python
# AI Agent monitors and adjusts BGP automatically
import requests
class BGPController:
def __init__(self, gobgp_url="http://192.168.100.1:8080"):
self.base_url = gobgp_url
def check_bgp_health(self):
"""Check BGP session health"""
resp = requests.get(f"{self.base_url}/v1/neighbors")
neighbors = resp.json()
for neighbor in neighbors:
if neighbor['state'] != 'established':
self.alert(f"BGP peer {neighbor['address']} is down!")
self.attempt_recovery(neighbor)
def announce_prefix(self, prefix, nexthop):
"""Programmatically announce a new prefix"""
requests.post(f"{self.base_url}/v1/routes", json={
"prefix": prefix,
"nexthop": nexthop
})
def withdraw_prefix(self, prefix):
"""Withdraw a prefix"""
requests.delete(f"{self.base_url}/v1/routes/{prefix}")
```
### Benefits
- ✅ **API-driven**: Control BGP programmatically
- ✅ **Automation-friendly**: Easy integration with CI/CD
- ✅ **Metrics built-in**: Native Prometheus support
- ✅ **Modern codebase**: Active development, Go ecosystem
- ✅ **Flexible**: Add custom logic in Go

## 🔄 Complete Workflow
### Initial Deployment
```bash
# 1. Define infrastructure in Terraform
cd terraform/
terraform init
terraform plan
terraform apply
# VMs created:
# - VM 200: Router (GoBGP)
# - VM 300: AI Agent
# - VM 500: NetBox
# - VM 600-603: K8s cluster (K3s)
# 2. Configure VMs with Ansible
cd ../ansible/
ansible-playbook -i inventory/hosts.yml playbooks/site.yml
# Installs:
# - GoBGP on Router
# - NetBox on VM 500
# - K3s on cluster VMs
# - Monitoring agents everywhere
# 3. Deploy applications to K8s
cd ../k8s/
kubectl apply -f backstage/
kubectl apply -f vapor-api/
kubectl apply -f monitoring/
# 4. Configure NetBox
# - Import IP allocations
# - Sync VMs from Proxmox
# - Document network topology
# 5. Start BGP
# - GoBGP establishes sessions
# - Routes announced automatically
# - Monitoring begins
```
### Day-2 Operations
**Add a new VM:**
```bash
# 1. Define in Terraform
cat >> terraform/vms.tf << 'EOF'
module "new_app_vm" {
source = "./modules/proxmox-vm"
vm_id = 700
name = "app-server"
# ...
}
EOF
# 2. Apply
terraform apply
# 3. Ansible configures automatically (if in inventory)
ansible-playbook -i inventory playbooks/app-server.yml
# 4. NetBox updated automatically via API
```
**Deploy new app to K8s:**
```bash
# 1. Create Kubernetes manifest
cat > k8s/myapp/deployment.yaml
# 2. Apply
kubectl apply -f k8s/myapp/
# 3. Monitoring auto-discovers new pods
# 4. Logs aggregated automatically
```
**Modify BGP routing:**
```bash
# Option 1: Via API
curl -X POST http://192.168.100.1:8080/v1/routes \
-d '{"prefix": "2602:F674:9000::/64", "nexthop": "..."}'
# Option 2: Via Terraform
# (if managing routes as code)
terraform apply
# Option 3: Via AI Agent
# (automatic based on conditions)
```

### Alerting
```yaml
# Prometheus Alert Rules
groups:
- name: infrastructure
rules:
- alert: BGPSessionDown
expr: gobgp_peer_state != 6
for: 5m
- alert: VMHighCPU
expr: node_cpu_usage > 90
for: 10m

## 🔐 Security Considerations
### Secrets Management
**Option 1: Ansible Vault**
```bash
ansible-vault encrypt group_vars/all.yml
```
**Option 2: HashiCorp Vault** (recommended)
```hcl
# Terraform reads secrets from Vault
data "vault_generic_secret" "proxmox" {
path = "secret/proxmox"
}
```
### Access Control
- **Terraform**: State encryption, remote backend
- **Ansible**: SSH key-based auth, vault for secrets
- **NetBox**: RBAC, API tokens
- **K8s**: RBAC, network policies, Pod security standards
- **GoBGP**: API authentication, mTLS

# ORION Terraform Infrastructure
Infrastructure as Code for the ORION Dell R730 Proxmox environment.
## 🚀 Quick Start
### Prerequisites
1. **Terraform** installed (>= 1.6.0)
```bash
# Install Terraform
wget https://releases.hashicorp.com/terraform/1.7.0/terraform_1.7.0_linux_amd64.zip
unzip terraform_1.7.0_linux_amd64.zip
sudo mv terraform /usr/local/bin/
```
2. **Proxmox API Token** created
```bash
# On Proxmox host, create API token:
pveum user add terraform@pam
pveum role add TerraformRole -privs "VM.Allocate VM.Clone VM.Config.CDROM VM.Config.CPU VM.Config.Cloudinit VM.Config.Disk VM.Config.HWType VM.Config.Memory VM.Config.Network VM.Config.Options VM.Monitor VM.Audit VM.PowerMgmt Datastore.AllocateSpace Datastore.Audit Pool.Allocate Sys.Audit Sys.Console Sys.Modify"
pveum aclmod / -user terraform@pam -role TerraformRole
pveum user token add terraform@pam terraform-token --privsep=0
# Save the token ID and secret that are displayed
```
3. **Cloud-init template** in Proxmox
```bash
# Create Ubuntu 24.04 cloud-init template
# (See detailed instructions in docs/proxmox-cloud-init-template.md)
```
### Setup
1. **Copy and configure variables:**
```bash
cp terraform.tfvars.example terraform.tfvars
nano terraform.tfvars
# Update:
# - proxmox_api_token_id
# - proxmox_api_token_secret
# - vm_ssh_keys
```
2. **Initialize Terraform:**
```bash
terraform init
```
3. **Plan deployment:**
```bash
terraform plan
```
4. **Apply configuration:**
```bash
terraform apply
```

## 🎯 What Gets Deployed
When you run `terraform apply`, the following VMs will be created:
### NetBox (VM 500)
- **Purpose**: IP Address Management and network documentation
- **Resources**: 4 cores, 8GB RAM, 100GB disk
- **IP**: 192.168.100.50
- **Services**: NetBox web UI, PostgreSQL, Redis
### Kubernetes Cluster (VMs 600-603)
- **Master** (VM 600): 4 cores, 8GB RAM
- **Workers** (VMs 601-603): 4 cores, 16GB RAM each
- **IP Range**: 192.168.100.60-63
## 🔧 Common Operations
### Check Current State
```bash
terraform show
terraform state list
```
### View Planned Changes
```bash
terraform plan
```
### Apply Changes
```bash
terraform apply
# Or auto-approve (skip confirmation)
terraform apply -auto-approve
```
### Destroy Infrastructure
```bash
# Destroy specific resource
terraform destroy -target=module.netbox_vm
# Destroy everything
terraform destroy
```
### Update a Single VM
```bash
# Taint a resource to force recreation
terraform taint module.netbox_vm.proxmox_vm_qemu.vm
terraform apply
```
### Import Existing VM
```bash
# Import an existing VM into Terraform state
terraform import module.router_vm.proxmox_vm_qemu.vm orion-pve/qemu/200
```
## 📊 Outputs
After applying, Terraform will output useful information:
```bash
terraform output
# Example outputs:
# netbox_ip = "192.168.100.50"
# netbox_url = "http://192.168.100.50:8000"
# k8s_master_ip = "192.168.100.60"
# k8s_worker_ips = ["192.168.100.61", "192.168.100.62", "192.168.100.63"]
```
## 🔐 Security
- **Never commit** `terraform.tfvars` or `*.tfstate` files
- **Use API tokens** instead of passwords
- **Encrypt state** if using remote backend
- **Limit token permissions** to minimum required
## 🐛 Troubleshooting
### "Error acquiring the state lock"
```bash
# Force unlock (use with caution)
terraform force-unlock <LOCK_ID>
```
### "Error creating VM: timeout while waiting"
```bash
# Increase timeout in provider configuration
# Or check Proxmox host resources
```
### "Template not found"
```bash
# Ensure cloud-init template exists:
qm list | grep template
# Or create it (see docs)
```
### API Token Permission Denied
```bash
# Verify token permissions:
pveum user token permissions terraform@pam terraform-token
```
## 🔄 Integration with Ansible
After Terraform creates VMs, use Ansible to configure them:
```bash
# Generate Ansible inventory from Terraform outputs
terraform output -json > ../ansible/inventory/terraform.json
# Run Ansible playbooks
cd ../ansible
ansible-playbook -i inventory/hosts.yml playbooks/site.yml
```
## 📚 Next Steps
1. **Create main.tf** - Define your infrastructure
2. **Customize modules** - Tailor VM configurations
3. **Set up remote state** - Use S3 or Consul backend
4. **Integrate with CI/CD** - Automate deployments
5. **Add monitoring** - Track infrastructure changes
## 📖 Documentation
- [Terraform Proxmox Provider](https://registry.terraform.io/providers/Telmate/proxmox/latest/docs)
- [Main Architecture](../INFRASTRUCTURE_AS_CODE_ARCHITECTURE.md)
- [ORION Overview](../README.md)
## ⚠️ Important Notes
- Always run `terraform plan` before `apply`
- Review changes carefully before confirming
- Keep state files secure and backed up
- Test in dev environment first
- Document any manual changes outside Terraform
