Old VM had incorrect hardware-configuration.nix with hardcoded UUIDs
that didn't match actual disk layout, causing boot failure (emergency mode).
Recreated using template2-based configuration for OpenTofu provisioning.

Remove pgdb1 host configuration and postgres service module.
The only consumer (Open WebUI on gunter) has migrated to local PostgreSQL.
Removed:
- hosts/pgdb1/ - host configuration
- services/postgres/ - service module (only used by pgdb1)
- postgres_rules from monitoring rules
- rebuild-all.sh (obsolete script)

- 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)

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.

Three permanent test hosts for validating deployment and bootstrapping
workflow. Each host configured with:
- Static IP (10.69.13.20-22/24)
- Vault AppRole integration
- Bootstrap from deploy-test-hosts branch

Update homelab-deploy to include bugfix. Add CLI to devShell for
easier testing and deployment operations.

Add homelab-deploy flake input and NixOS module for message-based
deployments across the fleet. Configure DEPLOY account in NATS with
tiered access control (listener, test-deployer, admin-deployer).
Enable listener on vaulttest01 as initial test host.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
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.

- Update nixos-exporter to 0.2.3
- Set system.configurationRevision for all hosts so the exporter
can report the flake's git revision

Add nixos-exporter prometheus exporter to track NixOS generation metrics
and flake revision status across all hosts.
Changes:
- Add nixos-exporter flake input
- Add commonModules list in flake.nix for modules shared by all hosts
- Enable nixos-exporter in system/monitoring/metrics.nix
- Configure Prometheus to scrape nixos-exporter on all hosts

Replace custom backup-helper flake input with NixOS native
services.restic.backups module for ha1, monitoring01, and nixos-test1.

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

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.
