This change was committed straight to main, bypassing the required PR review. Reverting main to baseline; the change is preserved on branch scrubs/gro-2536-gitops-fix-forward-rule and will land via PR review (GRO-2536). cc @cpfarhood

Infrastructure lifecycle for GroomBook. Governs work on the
|
|
groombook/infra repo: single-branch main strategy, the infra PR review
|
|
pipeline, Flux GitOps reconciliation, OpenTofu controller workflow,
|
|
cluster topology, and the Flux image-automation policy. For application
|
|
code, see the sdlc skill.

# DevOps Practices
|
|
|
|
This skill governs work on **`groombook/infra`**. For application code lifecycle, see the `sdlc` skill. For PR/test discipline and the `cc @cpfarhood` visibility rule, see `coding-standards`. For non-negotiable safety rules (no direct `tofu`, no `kubectl apply` to production, SealedSecrets), see `safety`.
|
|
|
|
## Gitea authentication
|
|
|
|
Use the `GITEA_TOKEN` environment variable for all Gitea operations — it is already set in the agent environment. Use the **`tea`** CLI for all Gitea/Git operations (e.g., `tea issue list`, `tea pr create`). Gitea is the primary source of truth.
|
|
|
|
## Branch strategy
|
|
|
|
`groombook/infra` uses a single long-lived branch: **`main`**. Engineers target `main` directly via feature branches named `<agent-name>/<short-description>`.
|
|
|
|
## Pipeline
|
|
|
|
1. **Engineer** branches from `main`, writes code.
|
|
2. **Engineer** opens a PR against `main`.
|
|
3. **CI** fail → back to **Engineer**.
|
|
4. **CI** pass → **QA** performs code review.
|
|
5. **QA** rejected → back to **Engineer**.
|
|
6. **QA** approved → **CTO** performs code review.
|
|
7. **CTO** rejected → back to **Engineer**.
|
|
8. **CTO** approved → **Engineer** merges PR → **Flux** reconciles automatically.
|
|
|
|
```bash
|
|
tea pr create --base main --title "..." --body "... cc @cpfarhood"
|
|
```
|
|
|
|
Gitea branch protection requires CI checks to pass. See `coding-standards` for the no-self-merge contract and the `cc @cpfarhood` rule.
|
|
|
|
## Infrastructure topology
|
|
|
|
* **Production:** namespace `groombook`, FQDN `demo.groombook.dev`
|
|
* **UAT:** namespace `groombook-uat`, FQDN `uat.groombook.dev`
|
|
* **Dev:** namespace `groombook-dev`, FQDN `dev.groombook.dev`
|
|
* **Cluster:** Kubernetes — cluster-wide read; read/write on `groombook-dev` and `groombook-uat`; read-only on `groombook` (production).
|
|
* **Gateways:** `istio-external` (public) and `istio-internal` (internal) in `gateway-system`.
|
|
* **Container registry:** `git.farh.net/groombook/<service>` only.
|
|
|
|
## GitOps (Flux)
|
|
|
|
Flux watches `groombook/infra` as the **target** GitRepository — it is **not** a Flux bootstrap/cluster repo and must never be treated as one.
|
|
|
|
Reconciles Kustomize overlays:
|
|
- `apps/overlays/dev` → `groombook-dev`
|
|
- `apps/overlays/uat` → `groombook-uat`
|
|
- `apps/overlays/prod` → `groombook`
|
|
|
|
Images currently use `:latest` with `imagePullPolicy: Always`; pin to a CalVer tag in the infra overlay when stabilizing a release.
|
|
|
|
**Policy — Flux Image Tag Automation is DENIED.** Do NOT use `ImageRepository`, `ImagePolicy`, or `ImageUpdateAutomation` Flux resources. Image tag updates must be made intentionally via a PR to `groombook/infra` — typically as the final step of the `sdlc` application pipeline (Phase 5).
|
|
|
|
## Infrastructure as Code
|
|
|
|
Terraform (OpenTofu) is deployed via the **Flux OpenTofu Controller** in a GitOps fashion. Submit Terraform configurations via a PR to `groombook/infra` — the tofu controller reconciles them on merge. See `safety` for the prohibition on running `tofu` directly and on `kubectl apply` against production.
|
|
|
|
## Infra-only tools
|
|
|
|
These are the operators and controllers the infra repo installs and manages. Alternatives are policy violations:
|
|
|
|
* **GitOps:** Flux CD (managed externally; reconciles `groombook/infra`).
|
|
* **IaC:** Flux OpenTofu Controller.
|
|
* **Secret management:** Bitnami Sealed Secrets Controller — encrypt with `kubeseal`, commit `SealedSecret` resources to `groombook/infra`. No plain Kubernetes secrets.
|
|
* **Database operator:** CloudNativePG (Postgres).
|
|
* **Cache / pub-sub operator:** DragonflyDB.
|
|
|
|
For application-level tool policy (Renovate, Playwright, registry, CalVer) see `coding-standards` and `sdlc`.
