- 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`):** + -

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/`). 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. diff --git a/scripts/check_gotify_gitops.py b/scripts/check_gotify_gitops.py new file mode 100644 index 0000000..4f8de56 --- /dev/null +++ b/scripts/check_gotify_gitops.py @@ -0,0 +1,20 @@ +import sys +import urllib.request +import json + +sys.stdout.reconfigure(encoding='utf-8') + +def main(): + req = urllib.request.Request('http://140.44.4.70:8090/message', headers={'X-Gotify-Key': 'C1dIsCoRdBrIdGeClIeN'}) + try: + with urllib.request.urlopen(req, timeout=5) as resp: + data = json.loads(resp.read().decode()) + messages = data.get('messages', []) + print(f"TOTAL MESSAGES IN GOTIFY: {len(messages)}") + for m in messages[:8]: + print(f"- [App {m.get('appid')}] {m.get('title')}: {m.get('message')[:80]}") + except Exception as e: + print("Error:", e) + +if __name__ == '__main__': + main()
