What are the most common scenarios for applying webhook notifications in Kubernetes Admission Controller?

Webhook notifications in Admission Controller Kubernetes are used for dynamic validation and modification of objects during their creation or update in the cluster. The most common scenarios:

• Resource validation: checking compliance of objects with security policies, for example, ensuring that pods are not launched with prohibited settings.
• Resource mutation: automatically adding or changing fields in objects, such as adding sidecar containers or annotations.
• Audit and logging: sending information about resource creation/modification events to external systems for monitoring.
• Ensuring compliance with standards: for example, controlling the use of certain container images or resource restrictions.

Thus, webhook notifications allow centralized management of cluster behavior and ensure security and standardization when working with Kubernetes resources.
