+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Repository Overview
+
+This is a Nix Flake-based NixOS configuration repository for managing a homelab infrastructure consisting of 16 server configurations. The repository uses a modular architecture with shared system configurations, reusable service modules, and per-host customization.
+
+## Common Commands
+
+### Building Configurations
+
+```bash
+# List all available configurations
+nix flake show
+
+# Build a specific host configuration locally (without deploying)
+nixos-rebuild build --flake .#<hostname>
+
+# Build and check a configuration
+nix build .#nixosConfigurations.<hostname>.config.system.build.toplevel
+```
+
+### Deployment
+
+Do not automatically deploy changes. Deployments are usually done by updating the master branch, and then triggering the auto update on the specific host.
+
+### Flake Management
+
+```bash
+# Check flake for errors
+nix flake check
+```
+Do not run `nix flake update`. Should only be done manually by user.
+
+### Development Environment
+
+```bash
+# Enter development shell (provides ansible, python3)
+nix develop
+```
+
+### Secrets Management
+
+Secrets are handled by sops. Do not edit any `.sops.yaml` or any file within `secrets/`. Ask the user to modify if necessary.
+
+### Git Commit Messages
+
+Commit messages should follow the format: `topic: short description`
+
+Examples:
+- `flake: add opentofu to devshell`
+- `template2: add proxmox image configuration`
+- `terraform: add VM deployment configuration`
+
+## Architecture
+
+### Directory Structure
+
+- `/flake.nix` - Central flake defining all 16 NixOS configurations
+- `/hosts/<hostname>/` - Per-host configurations
+  - `default.nix` - Entry point, imports configuration.nix and services
+  - `configuration.nix` - Host-specific settings (networking, hardware, users)
+- `/system/` - Shared system-level configurations applied to ALL hosts
+  - Core modules: nix.nix, sshd.nix, sops.nix, acme.nix, autoupgrade.nix
+  - Monitoring: node-exporter and promtail on every host
+- `/services/` - Reusable service modules, selectively imported by hosts
+  - `home-assistant/` - Home automation stack
+  - `monitoring/` - Observability stack (Prometheus, Grafana, Loki, Tempo)
+  - `ns/` - DNS services (authoritative, resolver)
+  - `http-proxy/`, `ca/`, `postgres/`, `nats/`, `jellyfin/`, etc.
+- `/secrets/` - SOPS-encrypted secrets with age encryption
+- `/common/` - Shared configurations (e.g., VM guest agent)
+- `/playbooks/` - Ansible playbooks for fleet management
+- `/.sops.yaml` - SOPS configuration with age keys for all servers
+
+### Configuration Inheritance
+
+Each host follows this import pattern:
+```
+hosts/<hostname>/default.nix
+  └─> configuration.nix (host-specific)
+      ├─> ../../system (ALL shared system configs - applied to every host)
+      ├─> ../../services/<service> (selective service imports)
+      └─> ../../common/vm (if VM)
+```
+
+All hosts automatically get:
+- Nix binary cache (nix-cache.home.2rjus.net)
+- SSH with root login enabled
+- SOPS secrets management with auto-generated age keys
+- Internal ACME CA integration (ca.home.2rjus.net)
+- Daily auto-upgrades with auto-reboot
+- Prometheus node-exporter + Promtail (logs to monitoring01)
+- Custom root CA trust
+
+### Active Hosts
+
+Production servers managed by `rebuild-all.sh`:
+- `ns1`, `ns2` - Primary/secondary DNS servers (10.69.13.5/6)
+- `ca` - Internal Certificate Authority
+- `ha1` - Home Assistant + Zigbee2MQTT + Mosquitto
+- `http-proxy` - Reverse proxy
+- `monitoring01` - Full observability stack (Prometheus, Grafana, Loki, Tempo, Pyroscope)
+- `jelly01` - Jellyfin media server
+- `nix-cache01` - Binary cache server
+- `pgdb1` - PostgreSQL database
+- `nats1` - NATS messaging server
+- `auth01` - Authentication service
+
+Template/test hosts:
+- `template1` - Base template for cloning new hosts
+- `nixos-test1` - Test environment
+
+### Flake Inputs
+
+- `nixpkgs` - NixOS 25.11 stable (primary)
+- `nixpkgs-unstable` - Unstable channel (available via overlay as `pkgs.unstable.<package>`)
+- `sops-nix` - Secrets management
+- Custom packages from git.t-juice.club:
+  - `backup-helper` - Backup automation module
+  - `alerttonotify` - Alert routing
+  - `labmon` - Lab monitoring
+
+### Network Architecture
+
+- Domain: `home.2rjus.net`
+- Infrastructure subnet: `10.69.13.x`
+- DNS: ns1/ns2 provide authoritative DNS with primary-secondary setup
+- Internal CA for ACME certificates (no Let's Encrypt)
+- Centralized monitoring at monitoring01
+- Static networking via systemd-networkd
+
+### Secrets Management
+
+- Uses SOPS with age encryption
+- Each server has unique age key in `.sops.yaml`
+- Keys auto-generated at `/var/lib/sops-nix/key.txt` on first boot
+- Shared secrets: `/secrets/secrets.yaml`
+- Per-host secrets: `/secrets/<hostname>/`
+- All production servers can decrypt shared secrets; host-specific secrets require specific host keys
+
+### Auto-Upgrade System
+
+All hosts pull updates daily from:
+```
+git+https://git.t-juice.club/torjus/nixos-servers.git
+```
+
+Configured in `/system/autoupgrade.nix`:
+- Random delay to avoid simultaneous upgrades
+- Auto-reboot after successful upgrade
+- Systemd service: `nixos-upgrade.service`
+
+### Proxmox VM Provisioning with OpenTofu
+
+The repository includes automated workflows for building Proxmox VM templates and deploying VMs using OpenTofu (Terraform).
+
+#### Building and Deploying Templates
+
+Template VMs are built from `hosts/template2` and deployed to Proxmox using Ansible:
+
+```bash
+# Build NixOS image and deploy to Proxmox as template
+nix develop -c ansible-playbook -i playbooks/inventory.ini playbooks/build-and-deploy-template.yml
+```
+
+This playbook:
+1. Builds the Proxmox image using `nixos-rebuild build-image --image-variant proxmox`
+2. Uploads the `.vma.zst` image to Proxmox at `/var/lib/vz/dump`
+3. Restores it as VM ID 9000
+4. Converts it to a template
+
+Template configuration (`hosts/template2`):
+- Minimal base system with essential packages (age, vim, wget, git)
+- Cloud-init configured for NoCloud datasource (no EC2 metadata timeout)
+- DHCP networking on ens18
+- SSH key-based root login
+- `prepare-host.sh` script for cleaning machine-id, SSH keys, and regenerating age keys
+
+#### Deploying VMs with OpenTofu
+
+VMs are deployed from templates using OpenTofu in the `/terraform` directory:
+
+```bash
+cd terraform
+tofu init     # First time only
+tofu apply    # Deploy VMs
+```
+
+Configuration files:
+- `main.tf` - Proxmox provider configuration
+- `variables.tf` - Provider variables (API credentials)
+- `vm.tf` - VM resource definitions
+- `terraform.tfvars` - Actual credentials (gitignored)
+
+Example VM deployment includes:
+- Clone from template VM
+- Cloud-init configuration (SSH keys, network, DNS)
+- Custom CPU/memory/disk sizing
+- VLAN tagging
+- QEMU guest agent
+
+OpenTofu outputs the VM's IP address after deployment for easy SSH access.
+
+### Adding a New Host
+
+1. Create `/hosts/<hostname>/` directory
+2. Copy structure from `template1` or similar host
+3. Add host entry to `flake.nix` nixosConfigurations
+4. Add hostname to dns zone files. Merge to master. Run auto-upgrade on dns servers.
+5. User clones template host
+6. User runs `prepare-host.sh` on new host, this deletes files which should be regenerated, like ssh host keys, machine-id etc. It also creates a new age key, and prints the public key
+7. This key is then added to `.sops.yaml`
+8. Create `/secrets/<hostname>/` if needed
+9. Configure networking (static IP, DNS servers)
+10. Commit changes, and merge to master.
+11. Deploy by running `nixos-rebuild boot --flake URL#<hostname>` on the host.
+
+### Important Patterns
+
+**Overlay usage**: Access unstable packages via `pkgs.unstable.<package>` (defined in flake.nix overlay-unstable)
+
+**Service composition**: Services in `/services/` are designed to be imported by multiple hosts. Keep them modular and reusable.
+
+**Hardware configuration reuse**: Multiple hosts share `/hosts/template/hardware-configuration.nix` for VM instances.
+
+**State version**: All hosts use stateVersion `"23.11"` - do not change this on existing hosts.
+
+**Firewall**: Disabled on most hosts (trusted network). Enable selectively in host configuration if needed.
+
+### Monitoring Stack
+
+All hosts ship metrics and logs to `monitoring01`:
+- **Metrics**: Prometheus scrapes node-exporter from all hosts
+- **Logs**: Promtail ships logs to Loki on monitoring01
+- **Access**: Grafana at monitoring01 for visualization
+- **Tracing**: Tempo for distributed tracing
+- **Profiling**: Pyroscope for continuous profiling
+
+### DNS Architecture
+
+- `ns1` (10.69.13.5) - Primary authoritative DNS + resolver
+- `ns2` (10.69.13.6) - Secondary authoritative DNS (AXFR from ns1)
+- Zone files managed in `/services/ns/`
+- All hosts point to ns1/ns2 for DNS resolution

+# TODO: Automated Host Deployment Pipeline
+
+## Vision
+
+Automate the entire process of creating, configuring, and deploying new NixOS hosts on Proxmox from a single command or script.
+
+**Desired workflow:**
+```bash
+./scripts/create-host.sh --hostname myhost --ip 10.69.13.50
+# Script creates config, deploys VM, bootstraps NixOS, and you're ready to go
+```
+
+**Current manual workflow (from CLAUDE.md):**
+1. Create `/hosts/<hostname>/` directory structure
+2. Add host to `flake.nix`
+3. Add DNS entries
+4. Clone template VM manually
+5. Run `prepare-host.sh` on new VM
+6. Add generated age key to `.sops.yaml`
+7. Configure networking
+8. Commit and push
+9. Run `nixos-rebuild boot --flake URL#<hostname>` on host

+
+**Status:** ✅ Fully implemented and tested
+**Completed:** 2025-02-01
+**Enhanced:** 2025-02-01 (added --force flag)
+
+**Goal:** Automate creation of host configuration files
+
+**Implementation:**

+
+---
+
+### Phase 3: Bootstrap Mechanism ✅ COMPLETED
+
+**Status:** ✅ Fully implemented and tested
+**Completed:** 2025-02-01
+**Enhanced:** 2025-02-01 (added branch support for testing)
+
+**Goal:** Get freshly deployed VM to apply its specific host configuration
+
+**Implementation:** Systemd oneshot service that runs on first boot after cloud-init
+
+**Approach taken:** Systemd service (variant of Option A)
+- Systemd service `nixos-bootstrap.service` runs on first boot
+- Depends on `cloud-config.service` to ensure hostname is set
+- Reads hostname from `hostnamectl` (set by cloud-init via Terraform)
+- Supports custom git branch via `NIXOS_FLAKE_BRANCH` environment variable
+- Runs `nixos-rebuild boot --flake git+https://git.t-juice.club/torjus/nixos-servers.git?ref=$BRANCH#${hostname}`
+- Reboots into new configuration on success
+- Fails gracefully without reboot on errors (network issues, missing config)
+- Service self-destructs after successful bootstrap (not in new config)
+
+**Tasks:**
+- [x] Create bootstrap service module in template2
+  - [x] systemd oneshot service with proper dependencies
+  - [x] Reads hostname from hostnamectl (cloud-init sets it)
+  - [x] Checks network connectivity via HTTPS (curl)
+  - [x] Runs nixos-rebuild boot with flake URL
+  - [x] Reboots on success, fails gracefully on error
+- [x] Configure cloud-init datasource
+  - [x] Use ConfigDrive datasource (Proxmox provider)
+  - [x] Add cloud-init disk to Terraform VMs (disks.ide.ide2.cloudinit)
+  - [x] Hostname passed via cloud-init user-data from Terraform
+- [x] Test bootstrap service execution on fresh VM
+- [x] Handle failure cases (flake doesn't exist, network issues)
+  - [x] Clear error messages in journald
+  - [x] No reboot on failure
+  - [x] System remains accessible for debugging
+
+**Files:**
+- `hosts/template2/bootstrap.nix` - Bootstrap service definition
+- `hosts/template2/configuration.nix` - Cloud-init ConfigDrive datasource
+- `terraform/vms.tf` - Cloud-init disk configuration
+
+**Deliverable:** ✅ VMs automatically bootstrap and reboot into host-specific configuration on first boot
+
+---
+
+### Phase 4: Secrets Management with HashiCorp Vault
+
+**Challenge:** Current sops-nix approach has chicken-and-egg problem with age keys
+
+**Current workflow:**
+1. VM boots, generates age key at `/var/lib/sops-nix/key.txt`
+2. User runs `prepare-host.sh` which prints public key
+3. User manually adds public key to `.sops.yaml`
+4. User commits, pushes
+5. VM can now decrypt secrets
+
+**Selected approach:** Migrate to HashiCorp Vault for centralized secrets management
+
+**Benefits:**
+- Industry-standard secrets management (Vault experience transferable to work)
+- Eliminates manual age key distribution step
+- Secrets-as-code via OpenTofu (infrastructure-as-code aligned)
+- Centralized PKI management (replaces step-ca, consolidates TLS + SSH CA)
+- Automatic secret rotation capabilities
+- Audit logging for all secret access
+- AppRole authentication enables automated bootstrap
+
+**Architecture:**
+```
+vault.home.2rjus.net
+  ├─ KV Secrets Engine (replaces sops-nix)
+  ├─ PKI Engine (replaces step-ca for TLS)
+  ├─ SSH CA Engine (replaces step-ca SSH CA)
+  └─ AppRole Auth (per-host authentication)
+       ↓
+   New hosts authenticate on first boot
+   Fetch secrets via Vault API
+   No manual key distribution needed
+```
+
+---
+
+#### Phase 4a: Vault Server Setup
+
+**Goal:** Deploy and configure Vault server with auto-unseal
+
+**Tasks:**
+- [ ] Create `hosts/vault01/` configuration
+  - [ ] Basic NixOS configuration (hostname, networking, etc.)
+  - [ ] Vault service configuration
+  - [ ] Firewall rules (8200 for API, 8201 for cluster)
+  - [ ] Add to flake.nix and terraform
+- [ ] Implement auto-unseal mechanism
+  - [ ] **Preferred:** TPM-based auto-unseal if hardware supports it
+    - [ ] Use tpm2-tools to seal/unseal Vault keys
+    - [ ] Systemd service to unseal on boot
+  - [ ] **Fallback:** Shamir secret sharing with systemd automation
+    - [ ] Generate 3 keys, threshold 2
+    - [ ] Store 2 keys on disk (encrypted), keep 1 offline
+    - [ ] Systemd service auto-unseals using 2 keys
+- [ ] Initial Vault setup
+  - [ ] Initialize Vault
+  - [ ] Configure storage backend (integrated raft or file)
+  - [ ] Set up root token management
+  - [ ] Enable audit logging
+- [ ] Deploy to infrastructure
+  - [ ] Add DNS entry for vault.home.2rjus.net
+  - [ ] Deploy VM via terraform
+  - [ ] Bootstrap and verify Vault is running
+
+**Deliverable:** Running Vault server that auto-unseals on boot
+
+---
+
+#### Phase 4b: Vault-as-Code with OpenTofu
+
+**Goal:** Manage all Vault configuration (secrets structure, policies, roles) as code
+
+**Tasks:**
+- [ ] Set up Vault Terraform provider
+  - [ ] Create `terraform/vault/` directory
+  - [ ] Configure Vault provider (address, auth)
+  - [ ] Store Vault token securely (terraform.tfvars, gitignored)
+- [ ] Enable and configure secrets engines
+  - [ ] Enable KV v2 secrets engine at `secret/`
+  - [ ] Define secret path structure (per-service, per-host)
+  - [ ] Example: `secret/monitoring/grafana`, `secret/postgres/ha1`
+- [ ] Define policies as code
+  - [ ] Create policies for different service tiers
+  - [ ] Principle of least privilege (hosts only read their secrets)
+  - [ ] Example: monitoring-policy allows read on `secret/monitoring/*`
+- [ ] Set up AppRole authentication
+  - [ ] Enable AppRole auth backend
+  - [ ] Create role per host type (monitoring, dns, database, etc.)
+  - [ ] Bind policies to roles
+  - [ ] Configure TTL and token policies
+- [ ] Migrate existing secrets from sops-nix
+  - [ ] Create migration script/playbook
+  - [ ] Decrypt sops secrets and load into Vault KV
+  - [ ] Verify all secrets migrated successfully
+  - [ ] Keep sops as backup during transition
+- [ ] Implement secrets-as-code patterns
+  - [ ] Secret values in gitignored terraform.tfvars
+  - [ ] Or use random_password for auto-generated secrets
+  - [ ] Secret structure/paths in version-controlled .tf files
+
+**Example OpenTofu:**
+```hcl
+resource "vault_kv_secret_v2" "monitoring_grafana" {
+  mount = "secret"
+  name  = "monitoring/grafana"
+  data_json = jsonencode({
+    admin_password = var.grafana_admin_password
+    smtp_password  = var.smtp_password
+  })
+}
+
+resource "vault_policy" "monitoring" {
+  name = "monitoring-policy"
+  policy = <<EOT
+path "secret/data/monitoring/*" {
+  capabilities = ["read"]
+}
+EOT
+}
+
+resource "vault_approle_auth_backend_role" "monitoring01" {
+  backend   = "approle"
+  role_name = "monitoring01"
+  token_policies = ["monitoring-policy"]
+}
+```
+
+**Deliverable:** All secrets and policies managed as OpenTofu code in `terraform/vault/`
+
+---
+
+#### Phase 4c: PKI Migration (Replace step-ca)
+
+**Goal:** Consolidate PKI infrastructure into Vault
+
+**Tasks:**
+- [ ] Set up Vault PKI engines
+  - [ ] Create root CA in Vault (`pki/` mount, 10 year TTL)
+  - [ ] Create intermediate CA (`pki_int/` mount, 5 year TTL)
+  - [ ] Sign intermediate with root CA
+  - [ ] Configure CRL and OCSP
+- [ ] Enable ACME support
+  - [ ] Enable ACME on intermediate CA (Vault 1.14+)

+  - [ ] Test certificate issuance on one host
+  - [ ] Roll out to all hosts via auto-upgrade
+- [ ] Migrate SSH CA trust
+  - [ ] Distribute Vault SSH CA public key to all hosts
+  - [ ] Update sshd_config to trust Vault CA
+  - [ ] Test SSH certificate authentication
+- [ ] Decommission step-ca
+  - [ ] Verify all services migrated
+  - [ ] Stop step-ca service on ca host
+  - [ ] Archive step-ca configuration for backup
+
+**Deliverable:** All TLS and SSH certificates issued by Vault, step-ca retired
+
+---
+
+#### Phase 4d: Bootstrap Integration
+
+**Goal:** New hosts automatically authenticate to Vault on first boot, no manual steps
+
+**Tasks:**
+- [ ] Update create-host tool
+  - [ ] Generate AppRole role_id + secret_id for new host
+  - [ ] Or create wrapped token for one-time bootstrap
+  - [ ] Add host-specific policy to Vault (via terraform)
+  - [ ] Store bootstrap credentials for cloud-init injection
+- [ ] Update template2 for Vault authentication
+  - [ ] Create Vault authentication module
+  - [ ] Reads bootstrap credentials from cloud-init
+  - [ ] Authenticates to Vault, retrieves permanent AppRole credentials
+  - [ ] Stores role_id + secret_id locally for services to use
+- [ ] Create NixOS Vault secrets module
+  - [ ] Replacement for sops.secrets
+  - [ ] Fetches secrets from Vault at nixos-rebuild/activation time
+  - [ ] Or runtime secret fetching for services
+  - [ ] Handle Vault token renewal
+- [ ] Update bootstrap service
+  - [ ] After authenticating to Vault, fetch any bootstrap secrets
+  - [ ] Run nixos-rebuild with host configuration
+  - [ ] Services automatically fetch their secrets from Vault
+- [ ] Update terraform cloud-init
+  - [ ] Inject Vault address and bootstrap credentials
+  - [ ] Pass via cloud-init user-data or write_files
+  - [ ] Credentials scoped to single use or short TTL
+- [ ] Test complete flow
+  - [ ] Run create-host to generate new host config
+  - [ ] Deploy with terraform
+  - [ ] Verify host bootstraps and authenticates to Vault
+  - [ ] Verify services can fetch secrets
+  - [ ] Confirm no manual steps required
+
+**Bootstrap flow:**
+```
+1. terraform apply (deploys VM with cloud-init)
+2. Cloud-init sets hostname + Vault bootstrap credentials
+3. nixos-bootstrap.service runs:
+   - Authenticates to Vault with bootstrap credentials
+   - Retrieves permanent AppRole credentials
+   - Stores locally for service use
+   - Runs nixos-rebuild
+4. Host services fetch secrets from Vault as needed
+5. Done - no manual intervention
+```
+
+**Deliverable:** Fully automated secrets access from first boot, zero manual steps
+
+---
+
+### Phase 5: DNS Automation
+
+**Goal:** Automatically generate DNS entries from host configurations
+
+**Approach:** Leverage Nix to generate zone file entries from flake host configurations
+
+Since most hosts use static IPs defined in their NixOS configurations, we can extract this information and automatically generate A records. This keeps DNS in sync with the actual host configs.
+
+**Tasks:**
+- [ ] Add optional CNAME field to host configurations
+  - [ ] Add `networking.cnames = [ "alias1" "alias2" ]` or similar option
+  - [ ] Document in host configuration template
+- [ ] Create Nix function to extract DNS records from all hosts
+  - [ ] Parse each host's `networking.hostName` and IP configuration
+  - [ ] Collect any defined CNAMEs
+  - [ ] Generate zone file fragment with A and CNAME records
+- [ ] Integrate auto-generated records into zone files
+  - [ ] Keep manual entries separate (for non-flake hosts/services)
+  - [ ] Include generated fragment in main zone file
+  - [ ] Add comments showing which records are auto-generated
+- [ ] Update zone file serial number automatically
+- [ ] Test zone file validity after generation
+- [ ] Either:
+  - [ ] Automatically trigger DNS server reload (Ansible)
+  - [ ] Or document manual step: merge to master, run upgrade on ns1/ns2
+
+**Deliverable:** DNS A records and CNAMEs automatically generated from host configs
+
+---
+
+### Phase 6: Integration Script
+
+**Goal:** Single command to create and deploy a new host
+
+**Tasks:**
+- [ ] Create `scripts/create-host.sh` master script that orchestrates:
+  1. Prompts for: hostname, IP (or DHCP), CPU, memory, disk
+  2. Validates inputs (IP not in use, hostname unique, etc.)
+  3. Calls host config generator (Phase 2)
+  4. Generates OpenTofu config (Phase 2)
+  5. Handles secrets (Phase 4)
+  6. Updates DNS (Phase 5)
+  7. Commits all changes to git
+  8. Runs `tofu apply` to deploy VM
+  9. Waits for bootstrap to complete (Phase 3)
+  10. Prints success message with IP and SSH command
+- [ ] Add `--dry-run` flag to preview changes
+- [ ] Add `--interactive` mode vs `--batch` mode
+- [ ] Error handling and rollback on failures
+
+**Deliverable:** `./scripts/create-host.sh --hostname myhost --ip 10.69.13.50` creates a fully working host
+
+---
+
+### Phase 7: Testing & Documentation
+
+**Status:** 🚧 In Progress (testing improvements completed)
+
+**Testing Improvements Implemented (2025-02-01):**
+
+The pipeline now supports efficient testing without polluting master branch:
+
+**1. --force Flag for create-host**
+- Re-run `create-host` to regenerate existing configurations
+- Updates existing entries in flake.nix and terraform/vms.tf (no duplicates)
+- Skip uniqueness validation checks
+- Useful for iterating on configuration templates during testing
+
+**2. Branch Support for Bootstrap**
+- Bootstrap service reads `NIXOS_FLAKE_BRANCH` environment variable
+- Defaults to `master` if not set
+- Allows testing pipeline changes on feature branches
+- Cloud-init passes branch via `/etc/environment`
+
+**3. Cloud-init Disk for Branch Configuration**
+- Terraform generates custom cloud-init snippets for test VMs
+- Set `flake_branch` field in VM definition to use non-master branch
+- Production VMs omit this field and use master (default)
+- Files automatically uploaded to Proxmox via SSH
+
+**Testing Workflow:**
+
+```bash
+# 1. Create test branch
+git checkout -b test-pipeline
+
+# 2. Generate or update host config
+create-host --hostname testvm01 --ip 10.69.13.100/24
+
+# 3. Edit terraform/vms.tf to add test VM with branch
+# vms = {
+#   "testvm01" = {
+#     ip = "10.69.13.100/24"
+#     flake_branch = "test-pipeline"  # Bootstrap from this branch
+#   }
+# }
+
+# 4. Commit and push test branch
+git add -A && git commit -m "test: add testvm01"
+git push origin test-pipeline
+
+# 5. Deploy VM
+cd terraform && tofu apply
+
+# 6. Watch bootstrap (VM fetches from test-pipeline branch)
+ssh root@10.69.13.100
+journalctl -fu nixos-bootstrap.service
+
+# 7. Iterate: modify templates and regenerate with --force
+cd .. && create-host --hostname testvm01 --ip 10.69.13.100/24 --force
+git commit -am "test: update config" && git push
+
+# Redeploy to test fresh bootstrap
+cd terraform
+tofu destroy -target=proxmox_vm_qemu.vm[\"testvm01\"] && tofu apply
+
+# 8. Clean up when done: squash commits, merge to master, remove test VM
+```
+
+**Files:**
+- `scripts/create-host/create_host.py` - Added --force parameter
+- `scripts/create-host/manipulators.py` - Update vs insert logic
+- `hosts/template2/bootstrap.nix` - Branch support via environment variable
+- `terraform/vms.tf` - flake_branch field support
+- `terraform/cloud-init.tf` - Custom cloud-init disk generation
+- `terraform/variables.tf` - proxmox_host variable for SSH uploads
+
+**Remaining Tasks:**
+- [ ] Test full pipeline end-to-end on feature branch
+- [ ] Update CLAUDE.md with testing workflow
+- [ ] Add troubleshooting section
+- [ ] Create examples for common scenarios (DHCP host, static IP host, etc.)
+
+---
+
+## Open Questions
+
+1. **Bootstrap method:** Cloud-init runcmd vs Terraform provisioner vs Ansible?
+2. **Secrets handling:** Pre-generate keys vs post-deployment injection?
+3. **DNS automation:** Auto-commit or manual merge?
+4. **Git workflow:** Auto-push changes or leave for user review?
+5. **Template selection:** Single template2 or multiple templates for different host types?
+6. **Networking:** Always DHCP initially, or support static IP from start?
+7. **Error recovery:** What happens if bootstrap fails? Manual intervention or retry?
+
+## Implementation Order
+
+Recommended sequence:
+1. Phase 1: Parameterize OpenTofu (foundation for testing)
+2. Phase 3: Bootstrap mechanism (core automation)
+3. Phase 2: Config generator (automate the boilerplate)
+4. Phase 4: Secrets (solves biggest chicken-and-egg)
+5. Phase 5: DNS (nice-to-have automation)
+6. Phase 6: Integration script (ties it all together)
+7. Phase 7: Testing & docs
+
+## Success Criteria
+
+When complete, creating a new host should:
+- Take < 5 minutes of human time
+- Require minimal user input (hostname, IP, basic specs)
+- Result in a fully configured, secret-enabled, DNS-registered host
+- Be reproducible and documented
+- Handle common errors gracefully
+
+---
+
+## Notes
+
+- Keep incremental commits at each phase
+- Test each phase independently before moving to next
+- Maintain backward compatibility with manual workflow
+- Document any manual steps that can't be automated

+# NixOS Host Configuration Generator
+
+Automated tool for generating NixOS host configurations, flake.nix entries, and Terraform VM definitions for homelab infrastructure.
+
+## Installation
+
+The tool is available in the Nix development shell:
+
+```bash
+nix develop
+```
+
+## Usage
+
+### Basic Usage
+
+Create a new host with DHCP networking:
+
+```bash
+python -m scripts.create_host.create_host create --hostname test01
+```
+
+Create a new host with static IP:
+
+```bash
+python -m scripts.create_host.create_host create \
+  --hostname test01 \
+  --ip 10.69.13.50/24
+```
+
+Create a host with custom resources:
+
+```bash
+python -m scripts.create_host.create_host create \
+  --hostname bighost01 \
+  --ip 10.69.13.51/24 \
+  --cpu 8 \
+  --memory 8192 \
+  --disk 100G
+```
+
+### Dry Run Mode
+
+Preview what would be created without making changes:
+
+```bash
+python -m scripts.create_host.create_host create \
+  --hostname test01 \
+  --ip 10.69.13.50/24 \
+  --dry-run
+```
+
+### Force Mode (Regenerate Existing Configuration)
+
+Overwrite an existing host configuration (useful for testing):
+
+```bash
+python -m scripts.create_host.create_host create \
+  --hostname test01 \
+  --ip 10.69.13.50/24 \
+  --force
+```
+
+This mode:
+- Skips hostname and IP uniqueness validation
+- Overwrites files in `hosts/<hostname>/`
+- Updates existing entries in `flake.nix` and `terraform/vms.tf` (doesn't duplicate)
+- Useful for iterating on configuration templates during testing
+
+### Options
+
+- `--hostname` (required): Hostname for the new host
+  - Must be lowercase alphanumeric with hyphens
+  - Must be unique (not already exist in repository)
+
+- `--ip` (optional): Static IP address with CIDR notation
+  - Format: `10.69.13.X/24`
+  - Must be in `10.69.13.0/24` subnet
+  - Last octet must be 1-254
+  - Omit this option for DHCP configuration
+
+- `--cpu` (optional, default: 2): Number of CPU cores
+  - Must be at least 1
+
+- `--memory` (optional, default: 2048): Memory in MB
+  - Must be at least 512
+
+- `--disk` (optional, default: "20G"): Disk size
+  - Examples: "20G", "50G", "100G"
+
+- `--dry-run` (flag): Preview changes without creating files
+
+- `--force` (flag): Overwrite existing host configuration
+  - Skips uniqueness validation
+  - Updates existing entries instead of creating duplicates
+
+## What It Does
+
+The tool performs the following actions:
+
+1. **Validates** the configuration:
+   - Hostname format (RFC 1123 compliance)
+   - Hostname uniqueness
+   - IP address format and subnet (if provided)
+   - IP address uniqueness (if provided)
+
+2. **Generates** host configuration files:
+   - `hosts/<hostname>/default.nix` - Import wrapper
+   - `hosts/<hostname>/configuration.nix` - Full host configuration
+
+3. **Updates** repository files:
+   - `flake.nix` - Adds new nixosConfigurations entry
+   - `terraform/vms.tf` - Adds new VM definition
+
+4. **Displays** next steps for:
+   - Reviewing changes with git diff
+   - Verifying NixOS configuration
+   - Verifying Terraform configuration
+   - Committing changes
+   - Deploying the VM
+
+## Generated Configuration
+
+### Host Features
+
+All generated hosts include:
+
+- Full system imports from `../../system`:
+  - Nix binary cache integration
+  - SSH with root login
+  - SOPS secrets management
+  - Internal ACME CA integration
+  - Daily auto-upgrades with auto-reboot
+  - Prometheus node-exporter
+  - Promtail logging to monitoring01
+
+- VM guest agent from `../../common/vm`
+- Hardware configuration from `../template/hardware-configuration.nix`
+
+### Networking
+
+**Static IP mode** (when `--ip` is provided):
+```nix
+systemd.network.networks."ens18" = {
+  matchConfig.Name = "ens18";
+  address = [ "10.69.13.50/24" ];
+  routes = [ { Gateway = "10.69.13.1"; } ];
+  linkConfig.RequiredForOnline = "routable";
+};
+```
+
+**DHCP mode** (when `--ip` is omitted):
+```nix
+systemd.network.networks."ens18" = {
+  matchConfig.Name = "ens18";
+  networkConfig.DHCP = "ipv4";
+  linkConfig.RequiredForOnline = "routable";
+};
+```
+
+### DNS Configuration
+
+All hosts are configured with:
+- DNS servers: `10.69.13.5`, `10.69.13.6` (ns1, ns2)
+- Domain: `home.2rjus.net`
+
+## Examples
+
+### Create a test VM with defaults
+
+```bash
+python -m scripts.create_host.create_host create --hostname test99
+```
+
+This creates a DHCP VM with 2 CPU cores, 2048 MB memory, and 20G disk.
+
+### Create a database server with static IP
+
+```bash
+python -m scripts.create_host.create_host create \
+  --hostname pgdb2 \
+  --ip 10.69.13.52/24 \
+  --cpu 4 \
+  --memory 4096 \
+  --disk 50G
+```
+
+### Preview changes before creating
+
+```bash
+python -m scripts.create_host.create_host create \
+  --hostname test99 \
+  --ip 10.69.13.99/24 \
+  --dry-run
+```
+
+## Error Handling
+
+The tool validates input and provides clear error messages for:
+
+- Invalid hostname format (must be lowercase alphanumeric with hyphens)
+- Duplicate hostname (already exists in repository)
+- Invalid IP format (must be X.X.X.X/24)
+- Wrong subnet (must be 10.69.13.0/24)
+- Invalid last octet (must be 1-254)
+- Duplicate IP address (already in use)
+- Resource constraints (CPU < 1, memory < 512 MB)
+
+## Integration with Deployment Pipeline
+
+This tool implements **Phase 2** of the automated deployment pipeline:
+
+1. **Phase 1**: Template building ✓ (build-and-deploy-template.yml)
+2. **Phase 2**: Host configuration generation ✓ (this tool)
+3. **Phase 3**: Bootstrap automation (planned)
+4. **Phase 4**: Secrets management (planned)
+5. **Phase 5**: DNS automation (planned)
+6. **Phase 6**: Full integration (planned)

+# OpenTofu Configuration for Proxmox
+
+This directory contains OpenTofu configuration for managing Proxmox VMs using a parameterized, multi-VM deployment system.
+
+## Setup
+
+1. **Create a Proxmox API token:**
+   - Log into Proxmox web UI
+   - Go to Datacenter → Permissions → API Tokens
+   - Click Add
+   - User: `root@pam`, Token ID: `terraform`
+   - Uncheck "Privilege Separation"
+   - Save the token secret (shown only once)
+
+2. **Configure credentials:**
+   ```bash
+   cd terraform
+   cp terraform.tfvars.example terraform.tfvars
+   # Edit terraform.tfvars with your Proxmox details
+   ```
+
+3. **Initialize OpenTofu:**
+   ```bash
+   tofu init
+   ```
+
+4. **Test connection:**
+   ```bash
+   tofu plan
+   ```
+
+## Defining VMs
+
+All VMs are defined in the `vms.tf` file in the `locals.vms` map. Each VM can specify custom configurations or use defaults from `variables.tf`.
+
+### Example: DHCP VM
+
+```hcl
+vms = {
+  "simple-vm" = {
+    cpu_cores = 2
+    memory    = 2048
+    disk_size = "20G"
+    # No "ip" field = DHCP
+  }
+}
+```
+
+### Example: Static IP VM
+
+```hcl
+vms = {
+  "web-server" = {
+    ip        = "10.69.13.50/24"
+    cpu_cores = 4
+    memory    = 4096
+    disk_size = "50G"
+  }
+}
+```
+
+### Example: Minimal VM (all defaults)
+
+```hcl
+vms = {
+  "test-vm" = {}
+}
+```
+
+### Example: Multiple VMs
+
+```hcl
+vms = {
+  "vm1" = {
+    ip = "10.69.13.50/24"
+  }
+  "vm2" = {
+    ip = "10.69.13.51/24"
+    cpu_cores = 4
+    memory = 8192
+  }
+  "vm3" = {
+    # DHCP
+    cpu_cores = 2
+    memory = 2048
+  }
+}
+```
+
+### Example: Test VM with Custom Git Branch
+
+For testing pipeline changes without polluting master:
+
+```hcl
+vms = {
+  "test-vm" = {
+    ip = "10.69.13.100/24"
+    flake_branch = "test-pipeline"  # Bootstrap from this branch
+  }
+}
+```
+
+This VM will bootstrap from the `test-pipeline` branch instead of `master`. Production VMs should omit the `flake_branch` field.
+
+## Configuration Options
+
+Each VM in the `vms` map supports the following fields (all optional):
+
+| Field | Description | Default |
+|-------|-------------|---------|
+| `ip` | Static IP with CIDR (e.g., "10.69.13.50/24"). Omit for DHCP | DHCP |
+| `gateway` | Network gateway (used with static IP) | `10.69.13.1` |
+| `cpu_cores` | Number of CPU cores | `2` |
+| `memory` | Memory in MB | `2048` |
+| `disk_size` | Disk size (e.g., "20G", "100G") | `"20G"` |
+| `flake_branch` | Git branch for bootstrap (for testing, omit for production) | `master` |
+| `target_node` | Proxmox node to deploy to | `"pve1"` |
+| `template_name` | Template VM to clone from | `"nixos-25.11.20260128.fa83fd8"` |
+| `storage` | Storage backend | `"local-zfs"` |
+| `bridge` | Network bridge | `"vmbr0"` |
+| `vlan_tag` | VLAN tag | `13` |
+| `ssh_public_key` | SSH public key for root | See `variables.tf` |
+| `nameservers` | DNS servers | `"10.69.13.5 10.69.13.6"` |
+| `search_domain` | DNS search domain | `"home.2rjus.net"` |
+
+Defaults are defined in `variables.tf` and can be changed globally.
+
+## Deployment Commands
+
+### Deploy All VMs
+
+```bash
+tofu apply
+```
+
+### Deploy Specific VM
+
+```bash
+tofu apply -target=proxmox_vm_qemu.vm[\"vm-name\"]
+```
+
+### Destroy Specific VM
+
+```bash
+tofu destroy -target=proxmox_vm_qemu.vm[\"vm-name\"]
+```
+
+### View Deployed VMs
+
+```bash
+tofu output vm_ips
+tofu output deployment_summary
+```
+
+### Plan Changes
+
+```bash
+tofu plan
+```
+
+## Outputs
+
+After deployment, OpenTofu provides two outputs:
+
+**vm_ips**: IP addresses and SSH commands for each VM
+```
+vm_ips = {
+  "vm1" = {
+    ip = "10.69.13.50"
+    ssh_command = "ssh root@10.69.13.50"
+  }
+}
+```
+
+**deployment_summary**: Full specifications for each VM
+```
+deployment_summary = {
+  "vm1" = {
+    cpu_cores = 4
+    memory_mb = 4096
+    disk_size = "50G"
+    ip = "10.69.13.50"
+    node = "pve1"
+  }
+}
+```
+
+## Workflow
+
+1. Edit `vms.tf` to define your VMs in the `locals.vms` map
+2. Run `tofu plan` to preview changes
+3. Run `tofu apply` to deploy
+4. Run `tofu output vm_ips` to get IP addresses
+5. SSH to VMs and configure as needed
+
+## Files
+
+- `main.tf` - Provider configuration
+- `variables.tf` - Variable definitions and defaults
+- `vms.tf` - VM definitions and deployment logic
+- `cloud-init.tf` - Cloud-init disk management (SSH keys, networking, branch config)
+- `outputs.tf` - Output definitions for deployed VMs
+- `terraform.tfvars.example` - Example credentials file
+- `terraform.tfvars` - Your actual credentials (gitignored)
+- `vm.tf.old` - Archived single-VM configuration (reference)
+
+## Notes
+
