Which directory holds environment-specific customizations for an app named myapp in the recommended structure?

• A. base
• B. production
• C. staging
• D. overlays

Answer: (D)

In a Kustomize-based setup, you separate the common resources from the environment-specific tweaks. The base holds the shared manifests for the application, while overlays contain the environment-specific customizations. Each environment (like production or staging) has its own subdirectory under overlays that references the base and applies patches or substitutions to tailor things like replicas, images, or environment variables for that environment. For an app named myapp, you’d keep the shared stuff in base and put the per-environment changes in overlays, with subdirectories such as overlays/production and overlays/staging. So the directory that holds environment-specific customizations is overlays.
