+# Cluster bootstrap & CD — two scopes
+
+The GitOps repo is hosted on the cluster's own Forgejo, so ArgoCD cannot pull it
+until Forgejo exists. There are two distinct workflows — pick the one that
+matches your situation.
+
+```
+Scope 1 — from scratch     cold cluster, nothing running yet   → full bootstrap
+Scope 2 — iterating CD     cluster + Forgejo + ArgoCD are up   → just git push
+```
+
+---
+
+## Scope 1 — Cluster from scratch (cold bootstrap)
+
+Strict ordering, because each layer depends on the previous one existing.
+
+```
+Talos + Cilium CNI          Terraform (nodes)                     — cluster reachable
+Substrate                   cert-manager, ingress-nginx, reloader — Terraform helm_releases
+                            Longhorn, ArgoCD                      — imperative install
+Phase 0 (git-independent)   CNPG + ddb-cluster + redis + Forgejo  — manual, below
+Seed                        git push repo into Forgejo
+Phase 1                     app-of-apps root                      — ArgoCD deploys the rest
+```
+
+Run every command from a local checkout with `KUBECONFIG` pointed at the cluster.
+
+### Phase 0 — bootstrap Forgejo and its data plane (git-independent)
+
+```bash
+# 1. CNPG operator (public Helm) + its CRDs.
+kubectl apply -f k8s/argocd/bootstrap/cnpg-operator.yaml
+argocd app sync cnpg-operator
+# CNPG ships CRDs in the chart's crds/ folder, which ArgoCD's helm-template does
+# NOT install. If the ddb-cluster apply below fails with "no matches for kind
+# Cluster", install them once:
+#   kubectl apply --server-side -f \
+#     https://raw.githubusercontent.com/cloudnative-pg/cloudnative-pg/release-1.24/releases/cnpg-1.24.1.yaml
+
+# 2. Namespaces first. cicd MUST be labelled privileged (DinD/runner needs it);
+#    the Forgejo app deliberately does NOT create it.
+kubectl create namespace ddb  --dry-run=client -o yaml | kubectl apply -f -

+### Seed + Phase 1
+
+```bash
+# 6. Push this repo to the freshly-created Forgejo so Phase 1 has a source.
+git remote add forgejo http://forgejo.riotpiao.com:3000/riotpiao.com/homelab.git
+git push forgejo main
+
+# 7. Deploy everything else from git — one sync brings up the whole cluster.
+kubectl apply -f k8s/argocd/projects/homelab-project.yaml   # AppProject
+kubectl apply -k k8s/argocd/root                            # app-of-apps root
+argocd app sync homelab-root
+```
+
+`homelab-root` renders every Application under `k8s/argocd/apps/` and syncs them
+in sync-wave order (networking → storage/observability → logging → security →
+data → messaging → applications).
+
+---
+
+## Scope 2 — Iterating CD (day-2, cluster already up)
+
+The app-of-apps and its children already exist and reconcile from Forgejo. To
+change anything, you do NOT re-run the bootstrap — you just push:
+
+```bash
+# edit manifests under k8s/**
+git add -A && git commit -m "..."
+git push                      # to Forgejo main (origin)
+# ArgoCD auto-syncs (child apps have syncPolicy.automated); to force it:
+argocd app sync homelab-root
+```
+
+- Adding a new service = add an Application manifest under `k8s/argocd/apps/`
+  and its manifests under the path it references, then push. The app-of-apps
+  picks it up on next sync.
+- Changing a Helm value = edit the values file the Application points at
+  (`$values/...`), push.
+- Forgejo itself is Phase-0 / bootstrap (manual sync only) — a bad CI commit
+  must not be able to break the system CI depends on.
+
+---
+
+## Notes / prerequisites
+
+- **Secrets:** several values files (loki S3, grafana admin, authentik, vault)
+  expect secrets that helmfile used to inject via `--set`. Under ArgoCD these
+  come from the `*.enc.yaml` SOPS files via the ArgoCD SOPS plugin — confirm the
+  plugin is configured before syncing waves 2–3, or those charts render with
+  empty secrets.
+- **Substrate** (cert-manager, ingress-nginx, reloader) is installed by Terraform
+  as bootstrap Helm releases, not ArgoCD. Cilium CNI, Longhorn, and ArgoCD
+  itself are cluster-bootstrap installs.
+- **Single storage node:** only `talos-cp-1` runs workloads/storage, so stateful
+  services are single-instance (`ddb-cluster` = 1). See the repo `USAGE.md` and
+  root `CLAUDE.md` topology section.
