Separate code and config
The app repository builds images. The config repository says which image runs where.
| Repository | Contains | Changed by |
|---|---|---|
shop (app) | Code, Dockerfile, tests, CI | Developers |
shop-deploy (config) | Kubernetes YAML, Helm values, Kustomize overlays | CI (image tag bumps) and reviewers |
platform (cluster) | Ingress controller, cert-manager, monitoring, policies | Platform team |
Use base and overlays
One base, small differences per environment with Kustomize (see Kustomize).

Use folders per environment on one main branch. Branches per environment drift apart and are hard to compare.
| Approach | Verdict |
|---|---|
| One branch, a folder per environment | Recommended: easy diff, one history |
| A branch per environment | Avoid: merges between environments, hidden differences |
| A repository per environment | Only for strict separation (different teams or clouds) |
Use Helm charts in GitOps
Keep the chart version and your values in Git; the GitOps tool renders and applies them.

Pin chart versions. An unpinned chart can change the cluster without any commit in your repository.
