Inevitably, digital transformation plans today rely on the scalability and flexibility of the cloud. While launching applications and services in the cloud presents many opportunities, it also comes
=> ↺ Kubernetes Validating Admission Policies: A Practical Example
Admission control is an important part of the Kubernetes control plane, with several internal features depending on the ability to approve or change an API object as it is submitted to the server. It is also useful for an administrator to be able to define business logic, or policies, regarding what objects can be admitted into a cluster. To better support that use case, Kubernetes introduced external admission control in v1.7.
In addition to countless custom, internal implementations, many open source projects and commercial solutions implement admission controllers with user-specified policy, including Kyverno and Open Policy Agent’s Gatekeeper.
While admission controllers for policy have seen adoption, there are blockers for their widespread use. Webhook infrastructure must be maintained as a production service, with all that entails. The failure case of an admission control webhook must either be closed, reducing the availability of the cluster; or open, negating the use of the feature for policy enforcement. The network hop and evaluation time makes admission control a notable component of latency when dealing with, for example, pods being spun up to respond to a network request in a "serverless" environment.
