RBAC Core Concepts – Users & ServiceAccounts | No.09 | Lesson 3-1 | Free CKA Kubernetes Course 2026

Описание: 🚀 Kubernetes Mastery – Lesson 3-1: Core RBAC Concepts – Users & ServiceAccounts

In this lesson, we focus on identity inside Kubernetes. Before we can control permissions, we must first understand who is requesting access. You’ll learn the difference between ServiceAccounts (for in-cluster workloads) and Users (for humans), and how Kubernetes authenticates each of them.

RBAC begins with identity — authorization comes next.

This video is part of our complete Kubernetes learning journey, designed for:
• Kubernetes beginners
• Cloud & DevOps engineers
• CKA (Certified Kubernetes Administrator) exam candidates

📘 Course Structure

This course consists of 8 structured lessons, each starting with a conceptual introduction followed by focused, hands-on videos.

In Certified Kubernetes Administrator – Kubernetes Mastery: From Cluster Setup to Troubleshooting, you’ll learn how to:

• Build and configure Kubernetes clusters from scratch
• Manage workloads, Deployments, Pods, and core configurations
• Master scheduling rules, node affinities, and automation tools
• Expose applications using Services and Ingress
• Configure storage and persistent volumes
• Debug, troubleshoot, and fix real-world Kubernetes issues

Through practical explanations and real-world architecture thinking, you’ll gain the confidence to operate production-ready clusters.

📚 Learning Agenda (This Video)

RBAC Foundation:
• Understanding the Subject in “Who can do what to which resources”
• Why identity must be established before permissions are assigned

ServiceAccounts (For In-Cluster Workloads):
• How ServiceAccounts work
• Default ServiceAccount behavior
• Assigning a ServiceAccount to a Pod
• Verifying permissions with kubectl auth can-i

Users (For Humans):
• Why Kubernetes does not store native User objects
• Certificate-based authentication workflow
• Generating private keys and CSRs
• Approving CertificateSigningRequests
• Testing authentication with kubectl

Key Takeaway:
• Authentication (identity) is separate from authorization (permissions)
• Users and ServiceAccounts start with zero privileges by default
