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: Proxmox VE Hardening
|
|
|
|
Applies Stage 1 hardening to a fresh Proxmox VE node using the `proxmox-hardening` Ansible role.
|
|
|
|
## Pre-conditions
|
|
|
|
- Fresh PVE install with root SSH access
|
|
- SSH key already added to root's `authorized_keys`
|
|
- Host added to `ansible/inventory/hosts.yml` under the `proxmox` group
|
|
|
|
## Steps
|
|
|
|
```bash
|
|
# 1. Verify connectivity
|
|
cd ansible
|
|
ansible-playbook playbooks/ping.yml --limit <hostname>
|
|
|
|
# 2. Dry-run to preview changes
|
|
ansible-playbook playbooks/proxmox.yml --limit <hostname> --check --diff
|
|
|
|
# 3. Review the diff output, then apply
|
|
ansible-playbook playbooks/proxmox.yml --limit <hostname>
|
|
|
|
# 4. Verify hardening state
|
|
ansible-playbook playbooks/proxmox.yml --limit <hostname> --tags audit --check
|
|
```
|
|
|
|
## What gets applied
|
|
|
|
1. **APT repos** — enterprise source disabled, no-subscription source enabled
|
|
2. **SSH hardening** — `PermitRootLogin prohibit-password`, `PasswordAuthentication no`, fail2ban
|
|
3. **Datacenter firewall** — default-deny inbound; SSH (22) and web UI (8006) from management CIDR only
|
|
4. **Unattended upgrades** — security-only origins, no auto-reboot
|
|
5. **Named admin user** — `<proxmox_admin_username>@pve` with Administrator role (one-time)
|
|
6. **IPA sudo** — `admins` group gets NOPASSWD sudo for shell and PVE tools
|
|
7. **Subscription nag** — cosmetic patch to remove the nag dialog
|
|
|
|
## Variables to set per-host
|
|
|
|
In `ansible/inventory/hosts.yml`:
|
|
```yaml
|
|
pve1.sweet.home:
|
|
proxmox_mgmt_cidr: "192.168.2.0/24"
|
|
proxmox_admin_username: wayne
|
|
```
|
|
|
|
## After hardening
|
|
|
|
- Log into the PVE web UI as the named admin, change the initial password
|
|
- Enable TOTP/2FA for both the named admin and root@pam
|
|
- Verify with the audit script: `cd /home/wayne/repos/debian-configuration && proxmox/scripts/audit.sh`
|
|
(will migrate to an Ansible audit task in a future iteration)
