In sintesi

Kustomize is a template-free customizer for K8s YAML. Define base manifests, then overlays (dev, staging, prod) that modify base via patches. No templating language, just YAML + strategic merge/JSON6902 patches. Mastery takes 3-4 weeks. Practitioners earn 15-25% premium because they reduce YAML boilerplate 40-50%. The 5% who design reusable kustomization patterns are valuable in platform teams.

Cos'è Kustomize Kubernetes Patches

Kustomize is a tool for customizing Kubernetes manifests without a templating language. You define base manifests (deployment, service, configmap), then overlays that patch the base for different environments (dev, staging, prod). Patches are declarative YAML files, no templating language (like Helm templates). Kustomize uses two patching strategies: strategic merge patches (merge YAML structures) and JSON6902 patches (surgical changes at specific JSON paths). Combined with generators (auto-create ConfigMaps/Secrets), it's powerful for managing manifests across environments.

❓ Domande frequenti

When should I use Kustomize vs. Helm?
Helm is a package manager (like apt, brew). Kustomize is a customizer. Helm good for 3rd-party applications (install, upgrade, remove). Kustomize good for own applications (customize manifests per environment). Can use both together.
What's a strategic merge patch?
Merge patch on K8s strategic merge. Define base deployment, then overlay strategic merge patch to change image tag, replica count, env vars. Patch merges with base, resulting in final manifest.
How do overlays work?
Overlay is a kustomization that patches a base. Example: base/ has deployment, service. dev/kustomization.yaml patches: 1 replica, image tag latest. prod/kustomization.yaml patches: 3 replicas, image tag v1.2.3. Same base, different overlays.
Can Kustomize generate ConfigMaps/Secrets?
Yes. Define in kustomization.yaml: configMapGenerator, secretGenerator. Kustomize auto-generates K8s ConfigMap/Secret with content. Hash suffix for auto-restart on config change.
How do I use Kustomize with CI/CD?
In CI pipeline: `kustomize build prod/ | kubectl apply -f -`. Build production overlay, apply to prod cluster. Same command for all environments (different overlay paths).
