New VMs bootstrapped from template2 will now use the local nix cache
during initial nixos-rebuild, speeding up bootstrap times.

ns1 needs access to shared/dns/* for zone transfer key and
shared/homelab-deploy/* for the NATS listener.

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)

Only consumer was Open WebUI on gunter, which will migrate to local
PostgreSQL. Removed pgdb1 backup/migration phases and added to
decommission list.

- ns2 migrated to OpenTofu
- testvm02, testvm03 added to managed hosts
- Remove vaulttest01 (no longer exists)

Configure Unbound to query both ns1 and ns2 for the home.2rjus.net
zone, in addition to local NSD. This provides redundancy during
bootstrap or if local NSD is temporarily unavailable.

Bootstrap times can be improved by configuring the base template
to use the local nix cache during initial builds.

- 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)

- Remove secrets/ directory (sops-nix no longer in use, all hosts use Vault)
- Move TODO.md to docs/plans/completed/automated-host-deployment-pipeline.md

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.

Remove the step-ca host and labmon flake input now that ACME has been
migrated to OpenBao PKI.
Removed:
- hosts/ca/ - step-ca host configuration
- services/ca/ - step-ca service module
- labmon flake input and module (no longer used)
Updated:
- flake.nix - removed ca host and labmon references
- flake.lock - removed labmon input
- rebuild-all.sh - removed ca from host list
- CLAUDE.md - updated documentation
Note: secrets/ca/ should be manually removed by the user.

- Add note that gh pr create is not supported
- Remove labmon from Prometheus job names list
- Remove labmon from flake inputs list

Set up a simple nginx server with an ACME certificate from the new
OpenBao PKI infrastructure. This allows testing the ACME migration
before deploying to production hosts.

Switch all ACME certificate issuance from step-ca (ca.home.2rjus.net)
to OpenBao PKI (vault.home.2rjus.net:8200/v1/pki_int/acme/directory).
- Update default ACME server in system/acme.nix
- Update Caddy acme_ca in http-proxy and nix-cache services
- Remove labmon service from monitoring01 (step-ca monitoring)
- Remove labmon scrape target and certificate_rules alerts
- Remove alloy.nix (only used for labmon profiling)
- Add docs/plans/cert-monitoring.md for future cert monitoring needs

Enable vault.enable and homelab.deploy.enable on vault01 so it can
receive NATS-based remote deployments. Vault fetches secrets from
itself using AppRole after auto-unseal.
Add systemd ordering to ensure vault-secret services wait for openbao
to be unsealed before attempting to fetch secrets.
Also adds vault01 AppRole entry to Terraform.

Enable vault.enable and homelab.deploy.enable for these hosts to
allow NATS-based remote deployments and expose metrics on port 9972.

Add instructions for deploying to prod hosts using the CLI directly,
since the MCP server only handles test-tier deployments.

Document the new hostname and host metadata labels available on all
Prometheus scrape targets:
- hostname: short hostname for easy filtering
- role: host role (dns, build-host, vault)
- tier: deployment tier (test for test VMs)
- dns_role: primary/secondary for DNS servers
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Add a `hostname` label to all Prometheus scrape targets, making it easy
to query all metrics for a host without wildcarding the instance label.
Example queries:
- {hostname="ns1"} - all metrics from ns1
- node_cpu_seconds_total{hostname="monitoring01"} - specific metric
For external targets (like gunter), the hostname is extracted from the
target string.

Extract homelab.host metadata (tier, priority, role, labels) from host
configurations and propagate them to Prometheus scrape targets. This
enables semantic alert filtering using labels instead of hardcoded
instance names.
Changes:
- lib/monitoring.nix: Extract host metadata, group targets by labels
- prometheus.nix: Use structured static_configs with labels
- rules.yml: Replace instance filters with role-based filters
Example labels in Prometheus:
- ns1/ns2: role=dns, dns_role=primary/secondary
- nix-cache01: role=build-host
- testvm*: tier=test

- Move nats-deploy-service.md to completed/ folder
- Update prometheus-scrape-target-labels.md with implementation status
- Add status table showing which steps are complete/partial/not started
- Update cross-references to point to new location

Adds log_to_loki function that pushes structured log entries to Loki
at key bootstrap stages (starting, network_ok, vault_*, building,
success, failed). Enables querying bootstrap state via LogQL without
console access.

TTY output was causing nixos-rebuild to fail. Keep the custom
greeting line to indicate bootstrap image, but use journal+console
for reliable logging.

Add a third play to build-and-deploy-template.yml that updates
terraform/variables.tf with the new template name after deploying
to Proxmox. Only updates if the template name has changed.
