admission-control

What problem does it solve?

Admission control intercepts Kubernetes resource create/update/delete requests for grafana-app-sdk apps to ensure invalid or malformed objects are rejected and necessary modifications are applied before persistence.

Core Features & Use Cases

• Validation Handlers: Implement Validator interfaces to accept or reject requests with clear, actionable error messages.
• Mutating Handlers: Implement Mutator interfaces to set defaults, normalize fields, or modify objects before they are saved.
• Use Case: Enforce immutability of critical fields, validate cross-field constraints, check referential integrity against other resources, and automatically populate defaults during resource creation.

Quick Start

Implement a Validator and/or Mutator for your resource type and register them in pkg/app/app.go so admission requests are handled before persistence.
