All hosts had identical nix-command/flakes settings in their
configuration.nix. Centralize in system/nix.nix so new hosts
(like pn01/pn02) get it automatically.

Remove monitoring01 host configuration and unused service modules
(prometheus, grafana, loki, tempo, pyroscope). Migrate blackbox,
exportarr, and pve exporters to monitoring02 with scrape configs
moved to VictoriaMetrics. Update alert rules, terraform vault
policies/secrets, http-proxy entries, and documentation to reflect
the monitoring02 migration.

- Remove hosts/template/ (legacy template1) and give each legacy host
its own hardware-configuration.nix copy
- Recreate ns2 using create-host with template2 base
- Add secondary DNS services (NSD + Unbound resolver)
- Configure Vault policy for shared DNS secrets
- Fix create-host IP uniqueness validator to check CIDR notation
(prevents false positives from DNS resolver entries)

All secrets are now managed by OpenBao (Vault). Remove the legacy
sops-nix infrastructure that is no longer in use.
Removed:
- sops-nix flake input
- system/sops.nix module
- .sops.yaml configuration file
- Age key generation from template prepare-host scripts
Updated:
- flake.nix - removed sops-nix references from all hosts
- flake.lock - removed sops-nix input
- scripts/create-host/ - removed sops references
- CLAUDE.md - removed SOPS documentation
Note: secrets/ directory should be manually removed by the user.

The homelab-deploy listener requires access to shared/homelab-deploy/*
secrets. Update hosts-generated.tf and the generator script to include
this policy automatically.

- Add vault.enable = true to testvm01, testvm02, testvm03
- Add homelab.deploy.enable = true for remote deployment via NATS
- Update create-host template to include these by default

- Remove host entries from terraform/vault/approle.tf on --remove
- Detect and warn about secrets in terraform/vault/secrets.tf
- Include vault kv delete commands in removal instructions
- Update check_entries_exist to return approle status

The regex patterns expected 6 spaces of indentation but flake.nix uses
8 spaces for host entries. Also updated generated entry template to
match current flake.nix style (using commonModules ++).

Add a shared `homelab.host` module that provides host metadata for
multiple consumers:
- tier: deployment tier (test/prod) for future homelab-deploy service
- priority: alerting priority (high/low) for Prometheus label filtering
- role: primary role of the host (dns, database, monitoring, etc.)
- labels: free-form labels for additional metadata
Host configurations updated with appropriate values:
- ns1, ns2: role=dns with dns_role labels
- nix-cache01: priority=low, role=build-host
- vault01: role=vault
- jump: role=bastion
- template, template2, testvm01, vaulttest01: tier=test, priority=low
The module is now imported via commonModules in flake.nix, making it
available to all hosts including minimal configurations like template2.

The read-based loop split multiline values on newlines, causing only
the first line to be written. Use jq -j to write each key's value
directly to files, preserving multiline content.

Fix bug where new hosts were added outside of nixosConfigurations block
instead of inside it.
Issues fixed:
1. Pattern was looking for "packages =" but actual text is "packages = forAllSystems"
2. Replacement was putting new entry AFTER closing brace instead of BEFORE
3. testvm01 was at top-level flake output instead of in nixosConfigurations
Changes:
- Update pattern to match "packages = forAllSystems"
- Put new entry BEFORE the closing brace of nixosConfigurations
- Move testvm01 to correct location inside nixosConfigurations block
Result: nix flake show now correctly shows testvm01 as NixOS configuration

Implement dual improvements to enable efficient testing of pipeline changes
without polluting master branch:
1. Add --force flag to create-host script
- Skip hostname/IP uniqueness validation
- Overwrite existing host configurations
- Update entries in flake.nix and terraform/vms.tf (no duplicates)
- Useful for iterating on configurations during testing
2. Add branch support to bootstrap mechanism
- Bootstrap service reads NIXOS_FLAKE_BRANCH environment variable
- Defaults to master if not set
- Uses branch in git URL via ?ref= parameter
- Service loads environment from /etc/environment
3. Add cloud-init disk support for branch configuration
- VMs can specify flake_branch field in terraform/vms.tf
- Automatically generates cloud-init snippet setting NIXOS_FLAKE_BRANCH
- Uploads snippet to Proxmox via SSH
- Production VMs omit flake_branch and use master
4. Update documentation
- Document --force flag usage in create-host README
- Add branch testing examples in terraform README
- Update TODO.md with testing workflow
- Add .generated/ to gitignore
Testing workflow: Create feature branch, set flake_branch in VM definition,
deploy with terraform, iterate with --force flag, clean up before merging.

Implements Phase 2 of the automated deployment pipeline.
This commit adds a Python CLI tool that automates the creation of NixOS host
configurations, eliminating manual boilerplate and reducing errors.
Features:
- Python CLI using typer framework with rich terminal UI
- Comprehensive validation (hostname format/uniqueness, IP subnet/uniqueness)
- Jinja2 templates for NixOS configurations
- Automatic updates to flake.nix and terraform/vms.tf
- Support for both static IP and DHCP configurations
- Dry-run mode for safe previews
- Packaged as Nix derivation and added to devShell
Usage:
create-host --hostname myhost --ip 10.69.13.50/24
The tool generates:
- hosts/<hostname>/default.nix
- hosts/<hostname>/configuration.nix
- Updates flake.nix with new nixosConfigurations entry
- Updates terraform/vms.tf with new VM definition
All generated configurations include full system imports (monitoring, SOPS,
autoupgrade, etc.) and are validated with nix flake check and tofu validate.
