Kubernetes 1.34 brings Mutating Admission Policy to beta!
To celebrate the occasion, I wrote a comprehensive tutorial on admission control: labs.iximiuz.com/tutorials/k...
Check it out if you're interested in a deep dive into Kubernetes admission control.

Mutating admission policies will graduate to beta in a few weeks: github.com/orgs/kubern...
If you find mutating admission webhooks challenging, even for simple mutations, this will be a game changer for you.

Although some ingress controllers can be set to use Service ClusterIP or NodePort, most resolve endpoints and route traffic directly to pods.
This approach grants the ingress gateway greater control over traffic routing and enables advanced features.

Is this how it works? If yes, why? If not, why not?

Kubernetes supports, in addition to admission webhooks:
- Conversion webhooks for Custom Resources
- Authorization webhooks to delegate authorization decisions to an external service

Admission webhooks are by far the most common webhooks that Kubernetes supports, but they are not the only ones.
Can you guess what other types of webhooks it supports?

As of Kubernetes 1.24, the management of the CNI is no longer within the scope of kubelet.
Kubelet now delegates this task to the container runtime via CRI.
