Transcription

Introduction

In this section, we will discuss Kubernetes access control. When we talk about Kubernetes access control, there are three stages: authentication, authorization, and admission.

Authentication

Now, whenever a request comes in, the authentication will check whether the credentials in the request are valid or not. If it's not valid, it's rejected at the authentication stage.

Authorization

Next is the authorization, which tells whether the user authenticated is allowed to operate. If it's not allowed, then the request is rejected at the authorization stage.

Admission

Finally comes the admission stage. So these are the admission controllers, and they are admission policies that apply to the cluster. Now, all the requests that do not violate any of the defined policies will go through, and if not, they will be rejected at the admission stage. Now, these are the typical three stages of Kubernetes access control. That's it for this lecture. Thanks for watching. See you in the next one.
