Consolidates nixos, docker, raspi, and debian-configuration into a single infrastructure-as-code repo. Includes: - ansible/: full inventory + proxmox-hardening, freeipa, and raspberrypi roles (converted from debian-configuration bash scripts) - terraform/: Proxmox VMs, Dynu DNS, Pi-hole (decommissioned stub), Docker container catalog — migrated from docker/infrastructure/terraform/ - stacks/docker/, stacks/raspi/, nixos/: placeholder READMEs pending git subtree population (see implementation plan) - docs/: internal MkDocs site with architecture, network topology, runbooks, and drift-detection guide; external sanitized site - scripts/: drift-detect.sh, docs-build.sh, install-hooks.sh, check-secrets.sh - CI: secret-scan (push/PR), drift-detect (daily), docs-build (on change) - Pi-hole removed throughout — DNS is FreeIPA, DHCP is router See docs/internal/implementation-plan.md for the phased rollout after pushing to Gitea.

Runbook: Drift Detection
How to interpret and respond to drift detected by the CI pipeline or local script.
What is drift?
Terraform drift — a Proxmox VM, DNS record, or Pi-hole entry exists in a different state than what's declared in the Terraform workspace. Common causes:
- A VM was resized or reconfigured manually in the PVE web UI
- A DNS record was added directly via Dynu or Pi-hole admin
- A VM was deleted outside of Terraform
Ansible drift — a host's configuration differs from what the Ansible role declares. Common causes:
- A config file was edited by hand on the host
- A package was installed/removed manually
- A service was stopped/disabled without updating the role
CI workflow
The drift-detect workflow runs daily at 06:00 AEST. If drift is detected, a Gotify
notification is sent to the push notification dashboard. The step summary in Gitea CI
contains the full terraform plan diff.
Responding to Terraform drift
# See exactly what changed
cd terraform/proxmox
terraform plan
# Option A: The manual change was intentional — update the .tf file to match reality,
# then run terraform apply to reconcile state
vim proxmox/docker.tf # update the resource to match current state
terraform apply
# Option B: The manual change was accidental — apply to restore declared state
terraform apply # will revert the manual change
Responding to Ansible drift
# See exactly what would change
cd ansible
ansible-playbook playbooks/site.yml --check --diff --limit <drifted_host>
# Apply to restore declared state
ansible-playbook playbooks/site.yml --limit <drifted_host>
