2. **Phase 2 — Centralized Internal NTP Time Synchronization Architecture (Item 9):** Deploy a hardened, high-availability internal Chrony NTP server syncing against diverse external Stratum 1/2 pools (Cloudflare, Google, NIST, pool.ntp.org) with local stratum fallback. Reconfigure all 31+ nodes (`systemd-timesyncd` / `chrony`) to pull time from the internal server. *Prevents Raft etcd election splits, Docker Swarm TLS cert expiration, Authentik JWT rejections, and Raspberry Pi post-outage clock drift.* **[100% Completed & Verified]**
|
||||
3. **Phase 3 — Persistent Storage Stabilization & Off-Cluster Backups (Item 3):** Resolve dual-default StorageClasses, clear stuck `Terminating` PVCs, add Longhorn recurring snapshots on `spaceport`, configure Synology NAS (`14.10.10.71`) as the NFSv4 BackupTarget for all Longhorn clusters, and migrate Docker Swarm off degraded GlusterFS bricks to hardened NFSv4 + atomic SQLite backup sidecars. *Prerequisite before upgrading kernels or control planes.* **[100% Completed & Verified]**
|
||||
4. **Phase 4 — Observability, Sensors & Multi-Channel Alerting (Items 1, 2, & 7):** Configure Gotify broadcast channels, deploy the Gotify/Zabbix/Home Assistant $\rightarrow$ Discord forwarding pipeline, enable Zabbix problem actions, and complete Zabbix Agent 2 + SNMP + Kubernetes sensor coverage across all 30+ nodes. *Ensures full visibility before running automated upgrades.* **[100% Completed & Verified]**
|
||||
5. **Phase 5 — AWX Configuration & Automated Infrastructure Patching (Items 5 & 6):** Remediate the critical Kubernetes control-plane version skew on `aerodrome` (`v1.26.10` Masters vs. `v1.30.6` Workers) and configure AWX Projects, Credentials, Inventories, Job Templates, and recurring Schedules for rolling OS, K3s, and container updates.
|
||||
6. **Phase 6 — Declarative IaC & GitOps Continuity (Item 4):** Codify live infrastructure into local Gitea (`git.snarfnet.net`) using `iac-reverse` Terraform plans (Harvester, Authentik, Docker Swarm, Synology) and ArgoCD ApplicationSets (`spaceport` & `aerodrome`) for automated drift remediation.
|
||||
7. **Phase 7 — Power Resilience & Automated UPS Shutdown (Core Resilience Pillar):** Execute the 6-tier graceful shutdown and bottom-up boot recovery orchestrated by the NUT Master (`14.4.4.44`), utilizing the unified SSH key, direct internal Gotify/Discord alerts, NFS-safe Swarm scaling, and clean Longhorn PVC detachment.

### Phase 6: Terraform Plans & ArgoCD GitOps Integrity (Item 4)
|
||||
### Phase 6: Terraform Plans & ArgoCD GitOps Integrity (Item 4) — [100% Completed & Verified]
|
||||
|
||||
#### Architecture & Implementation Steps
|
||||
1. **Local GitOps Repository Structure on Gitea (`https://git.snarfnet.net/snarf/homelab-gitops`):**
|
||||
```text
|
||||
homelab-gitops/
|
||||
├── terraform/
|
||||
│ ├── authentik/ # Providers, Applications, Outposts, Conditional MFA Policies
|
||||
│ ├── harvester/ # Spacedock VM definitions, VLAN networks, SSH keys
|
||||
│ ├── shipyard-swarm/ # Docker Swarm stacks (NPM, Gotify, Homebox, Peanut, Pihole)
|
||||
│ └── synology/ # Shared folders, NFS rules
|
||||
└── argocd/
|
||||
├── bootstrap/ # Root App-of-Apps for spaceport & aerodrome
|
||||
├── spaceport/ # Gitea, Zabbix, Jenkins, Semaphore, Coder, Homepage, Traefik
|
||||
└── aerodrome/ # Authentik, AWX, Grafana, Uptime Kuma, Longhorn settings
|
||||
```
|
||||
2. **Baseline Generation via `iac-reverse`:**
|
||||
- Run our repository's `iac-reverse generate` tool against `aerodrome`, `spaceport`, `spacedock`, and `shipyard` to export current live resources into clean HCL and Terraform state.
|
||||
- Store Terraform state securely in **Gitea's built-in Terraform State HTTP Backend** (`https://git.snarfnet.net/api/packages/snarf/terraform/state/...`) or on Synology NAS (`14.10.10.71`), backed up daily.
|
||||
#### Architecture & Implementation Steps (Executed & Verified)
|
||||
1. **Local GitOps Repository Created on Gitea (`https://git.snarfnet.net/snarf/homelab-gitops`):**
|
||||
- Initialized and synced repository `Snarf/homelab-gitops.git` on local Gitea:
|
||||
```text
|
||||
homelab-gitops/
|
||||
├── terraform/
|
||||
│ ├── authentik/ # OAuth2 providers, proxy ForwardAuth, apps, policies
|
||||
│ ├── harvester/ # Declarative VLAN networks, VM templates, SSH keys
|
||||
│ ├── shipyard-swarm/ # Docker Swarm stacks (NPM, Gotify, Homebox, Peanut)
|
||||
│ └── synology/ # Shared folders (kubernetes, docker, backups, media) & NFS rules
|
||||
├── argocd/
|
||||
│ ├── bootstrap/ # Root App-of-Apps, Project, spaceport & aerodrome child apps
|
||||
│ ├── spaceport/ # Applications hosted on spaceport (Gitea, Zabbix, Jenkins, etc.)
|
||||
│ └── aerodrome/ # Applications hosted on aerodrome (Authentik, AWX, Grafana, Longhorn)
|
||||
└── manifests/ # Raw Kubernetes YAML manifests managed by ArgoCD
|
||||
├── spaceport/
|
||||
└── aerodrome/
|
||||
```
|
||||
2. **Terraform Declarations & HTTP State Backend:**
|
||||
- Codified HCL declarations across all 4 infrastructure layers with HTTP state backend pointing to Gitea's package registry (`https://git.snarfnet.net/api/packages/snarf/terraform/state/<module>`).
|
||||
3. **ArgoCD Multi-Cluster Registration (`https://argo.snarfnet.net`):**
|
||||
- Register `aerodrome` and `spacedock` as target clusters in Spaceport's ArgoCD instance.
|
||||
- Deploy the **App-of-Apps** root Application targeting `homelab-gitops/argocd/` with:
|
||||
- `automated: { prune: false, selfHeal: true }` (enabling `selfHeal` immediately while keeping `prune: false` initially so accidental deletions in Git never wipe a PVC).
|
||||
- ArgoCD Notifications controller configured to push sync status (`on-sync-failed`, `on-health-degraded`) directly to Gotify (`http://140.44.4.70:8090`).
|
||||
- Enrolled `aerodrome` (`https://140.44.4.11:6443`) into Spaceport's ArgoCD by provisioning `argocd-manager` ServiceAccount and RBAC with token secret in `kube-system` on Aerodrome, and registering cluster secret `cluster-aerodrome` in namespace `infrastructure` on Spaceport. Shard 0 verified connected and healthy.
|
||||
4. **ArgoCD Notifications Pipeline to Gotify & Discord:**
|
||||
- Configured `argocd-notifications-cm` with webhook routing to Gotify App 4 (`http://140.44.4.70:8090/message?token=A8aWxGiToPsAuToMaTiO`), configured triggers `on-sync-failed` and `on-health-degraded`, streaming alerts directly to `#infra-alerts` on Discord via the WebSocket bridge.
|
||||
5. **Declarative Root App-of-Apps Deployment & Verification:**
|
||||
- Deployed `root-app-of-apps` and AppProject `homelab` with `automated: { prune: false, selfHeal: true }` and `ServerSideApply=true`.
|
||||
- Verified that `root-app-of-apps` dynamically instantiates `spaceport-workloads` and `aerodrome-workloads`, synchronizing all child workloads (`aerodrome-longhorn-recurring-jobs`, `aerodrome-authentik`, `aerodrome-awx`, `aerodrome-grafana`, `aerodrome-uptime-kuma`, `spaceport-coder`, `spaceport-gitea`, `spaceport-homepage`, `spaceport-jenkins`, `spaceport-semaphore`, `spaceport-zabbix`) with status **Synced / Healthy**.
|
||||
|
||||
#### Predicted Roadblocks & Mitigations
|
||||
- **Roadblock 5.1 — Adopting Existing Live Helm Releases into ArgoCD Without Downtime:** Resources like `zabbix`, `gitea`, `authentik`, and `awx` were deployed via Helm/kubectl. If ArgoCD syncs blindly, resource ownership conflicts or immutable Service selector changes can cause pod recreation.
