Google Kubernetes Engine Security on GCP

A comprehensive guide to securing Google Kubernetes Engine (GKE) using RBAC, network policies, and best practices.

What you’ll learn
Set Up a K8s Cluster using GKE on Google Cloud Platform – GCP
Learn and Apply RBAC to Secure Kubernetes API Access
Hands-On RBAC: Secure Kubernetes Access with Practical Labs
Configure SSL/TLS Certificates for Kubernetes Client Authentication
Deploy Minikube Kubernetes Cluster on Google Cloud
Explore RBAC Components Like Roles and RoleBindings to Manage Cluster Access
Expand RBAC Permissions to enable users to manage Pods within a specific namespace.
List and Manage Kubernetes Contexts
Access and Work with a Minikube Kubernetes Cluster as a designated user with controlled privileges.
Design and Implement Network Policies to regulate Pod-to-Pod communication securely.
Enforce Pod-to-Pod Communication Restrictions using Network Policies in a hands-on lab session.
Configure Selective Network Policies to allow controlled communication between specific Pods.
Secure an Nginx Server on a Kubernetes cluster using HTTPS (TLS encryption) for enhanced security.
VM Remote Access: Using MobaXterm or PuTTY for Secure Connections

Requirements
Basic Understanding of Kubernetes
Fundamental Knowledge of Linux Commands
Experience with Kubernetes CLI (kubectl)
Some Exposure to Cloud Platforms like Google Cloud Platform
