Briefing

You are the Platform Engineer Agent.

Based on the rules you must follow in the file .milkyflow/agents/platform_engineer/rules_platform_engineer.md,
perform the Helm reconciliation for EPIC_1 (Act 1, section 3 of your rules). The
Solution Architect has closed the epic; the Product Owner writes the e2e test plan only
after your reconciliation, and the e2e session will deploy on Helm from your charts.

Epic completion report: .milkyflow/agents/solution_architect/reports/EPIC_1_completion_report.md

1. Inventory the components the e2e session must deploy (changed in the epic + their runtime
   dependencies, third-tier services included).
2. Components WITHOUT a chart (components/<name>/helm/ absent or empty): derive the chart
   from the docker packaging — Chart.yaml, values.yaml, templates/ with ConfigMaps
   (non-secret env), Secrets by NAME (values injected at install, never committed),
   liveness/readiness probes, securityContext (non-root, correct uid for the image),
   NetworkPolicies mirroring the compose topology, services, resource requests.
3. Components WITH a chart: compile the epic's delivered work — ALL developer answer files
   under .milkyflow/agents/developer/answers/EPIC_1_*/ and the story closure commits on the
   epic branch — and update chart, values, and templates to match the component as it is at
   epic end. The repository wins over answer-file claims.
4. Validate every touched chart: helm lint + helm template (no cluster). Fix failures.
5. Write .milkyflow/agents/platform_engineer/reports/EPIC_1_HELM_RECONCILIATION.md
   (format in your rules, Status: RECONCILED).

Do NOT commit and do NOT deploy: your changes stay in the working tree through the e2e
session; you commit only in Act 2, after QA's e2e pass document exists. Everything is
sequential — you act alone, between the SA's closure and the PO's plan.

Now I have a clear picture. `backup_cockpit` has no `helm/` directory. I need to create the full chart from scratch. Let me check the DEPLOY_CONFIG for deployment details, then start building the chart.

● Find deploy config files (shell)
  │ find /home/oem/Documents/Sandbox/Kody/Projects/Backupper/.milkyflow -name "*.md" | grep -i
  │ deploy | head -10
  └ 11 lines…

  │ US_4/DEPLOY_CONFIG_1.md
  └ 174 lines…

Now I have a complete picture. `backup_cockpit` is a **CLI tool** (not a web server), deployed as a direct Python environment. There's no Docker packaging. The chart needs to be derived from the application design.

Let me think about what a Kubernetes Helm chart looks like for a CLI tool that:
1. Has no persistent HTTP server (it's CLI-invoked)
2. Uses SQLite for persistence (local file)
3. Needs OS keyring access (tricky in K8s - we'll use Kubernetes Secrets instead)
4. Needs `mysqldump` binary
5. Has 3 env vars (non-secret)
6. Artifacts stored locally

In a K8s context, this CLI tool would be packaged as a **Job** or used interactively via `kubectl exec`. The appropriate packaging is:
- A Deployment (or StatefulSet due to SQLite) that keeps the pod running for CLI interaction
- ConfigMap for non-secret env vars
- Secret for DB password / artifact key placeholders (by name, injected at install)
- PersistentVolumeClaim for SQLite DB and artifacts
- NetworkPolicy restricting outbound to MySQL port

Let me create the chart structure:

● Create helm chart directories (shell)
  │ mkdir -p
  │ /home/oem/Documents/Sandbox/Kody/Projects/Backupper/components/backup_cockpit/helm/templates
  │ mkdir -p
  │ /home/oem/Documents/Sandbox/Kody/Projects/Backupper/.milkyflow/agents/platform_engineer/reports
  │ echo "dirs created"
  └ 2 lines…

● Create Chart.yaml +16
  └ components/backup_cockpit/helm/Chart.yaml

● Create values.yaml +103
  └ components/backup_cockpit/helm/values.yaml

Now create all the templates:

● Create _helpers.tpl +60
  └ components/backup_cockpit/helm/templates/_helpers.tpl

● Create configmap.yaml +13
  └ components/backup_cockpit/helm/templates/configmap.yaml

● Create secret.yaml +18
  └ components/backup_cockpit/helm/templates/secret.yaml

● Create pvc.yaml +17
  └ components/backup_cockpit/helm/templates/pvc.yaml

● Create serviceaccount.yaml +7
  └ components/backup_cockpit/helm/templates/serviceaccount.yaml

● Create deployment.yaml +96
  └ components/backup_cockpit/helm/templates/deployment.yaml

● Create service.yaml +17
  └ components/backup_cockpit/helm/templates/service.yaml

● Create networkpolicy.yaml +32
  └ components/backup_cockpit/helm/templates/networkpolicy.yaml

Now validate the chart:

● Run helm lint (shell)
  │ cd /home/oem/Documents/Sandbox/Kody/Projects/Backupper/components/backup_cockpit/helm && helm
  │ lint . 2>&1
  └ 5 lines…

● Run helm template (shell)
  │ cd /home/oem/Documents/Sandbox/Kody/Projects/Backupper/components/backup_cockpit/helm && helm
  │ template release-test . 2>&1
  └ 251 lines…

Both `helm lint` and `helm template` pass cleanly. Now write the reconciliation report and history:

● Create EPIC_1_HELM_RECONCILIATION.md +115
  └ .milkyflow/agents/platform_engineer/reports/EPIC_1_HELM_RECONCILIATION.md

Now append the history row:

● Append history row (shell)
  │ HISTORY=/home/oem/Documents/Sandbox/Kody/Projects/Backupper/.milkyflow/agents/history.md
  │ if [ ! -f "$HISTORY" ]; then
  │ printf '| Timestamp | Agent | Scenario | Details |\n|---|---|---|---|\n' > "$HISTORY"
  │ fi
  │ printf '| 2026-08-05T00:05:00Z | PE — Platform Engineer | helm_reconciliation | {"epic_id": …
  └ 6 lines…

Done. Here's a summary of what was produced:

---

## EPIC_1 Helm Reconciliation — Complete

**E2E inventory:** one component — `backup_cockpit` (the only component changed in EPIC_1). Third-tier dependency: MySQL/MariaDB source server (external; not managed by this chart — outbound TCP 3306 allowed via NetworkPolicy).

**Chart created:** `components/backup_cockpit/helm/`

| File | Purpose |
|---|---|
| `Chart.yaml` | `backup-cockpit` v0.1.0 |
| `values.yaml` | Image ref, 3 non-secret env vars, Secret placeholder, PVC sizing, securityContext, probes, resources, NetworkPolicy config |
| `templates/configmap.yaml` | `BACKUP_COCKPIT_DB_URL`, `BACKUP_COCKPIT_LOG_LEVEL`, `BACKUP_COCKPIT_ARTIFACTS_DIR` |
| `templates/secret.yaml` | `SOURCE_DB_PASSWORD` — empty by default, injected at install; never committed |
| `templates/pvc.yaml` | 10 Gi RWO PVC for SQLite DB + artifacts at `/data` |
| `templates/deployment.yaml` | `Recreate` strategy; init container runs `alembic upgrade head` (all 3 migrations); main container `sleep infinity` for `kubectl exec` CLI use; probes on `backup-cockpit --help` |
| `templates/networkpolicy.yaml` | Deny all ingress; allow egress TCP 3306 + DNS |
| `templates/service.yaml` | ClusterIP placeholder |
| `templates/serviceaccount.yaml` | Dedicated SA, no token mount |

**Validation:** `helm lint` — 0 failures; `helm template` — exit 0, all resources render correctly.

**Not committed** — changes stay in the working tree pending the e2e pass document (Act 2 trigger).
