Admission Controllers in Kubernetes are a crucial aspect of securing and governing the behavior of your clusters. They provide a way to intercept and modify Kubernetes API requests, enabling you to implement additional control and validation mechanisms. These controllers are invoked every time a resource is created, updated, or deleted within the cluster.
How Admission Controllers Work
Admission Controllers in Kubernetes are executed in a specific order, allowing you to define a chain of checks and modifications. Each controller can either allow or deny the request based on its specific rules and logic. If a controller denies the request, the operation is blocked, and the API server returns an error message. This process ensures that all resources created or modified within the cluster meet the defined criteria and security standards.
