Build production Kubernetes on GCP

Short summary

This tutorial demonstrates building a production-ready Kubernetes cluster on GCP with automatic node joining, self-healing, and CPU-based autoscaling. It covers using GCP Startup Scripts and Instance Templates to automatically provision and configure nodes, then validates the setup using artificial CPU load to trigger scale-up events. While managed GKE offers convenience, understanding the manual build process creates more capable operators.

• •Automate node joining via GCP Startup Scripts with permanent kubeadm tokens
• •Configure Regional Managed Instance Groups (MIGs) for multi-zone high availability and self-healing
• •Set CPU-based autoscaling to dynamically add/remove nodes based on cluster load
