Inside Kubernetes RBAC
Table of Contents
Kubernetes is a Container Orchestration Engine designed to host containerized applications on a set of nodes, commonly referred to as a cluster. Using a systems modeling approach, this series aims to advance the understanding of Kubernetes and its underlying concepts. The Kubernetes API is an Http API that provides Create/Read/Update/Delete access to query and modify the Kubernetes Object Store.
Kubernetes supports multiple authentication and authorization strategies to control the access to the API. This post provides a concise, detailed model of Kubernetes’ Role-based Access Control (RBAC), but may not be suitable as introductory material. The model is supported by partial specifications in TLA+.
Conceptually, general authorization may be modeled as a relation hasAccess between a requesting user and a requested operation.
