Helm Tutorial for Beginners 🚀 Deploy, Upgrade & Rollback Apps on Kubernetes

Learn Helm on Kubernetes with this complete beginner-friendly hands-on tutorial where we install Helm, deploy an NGINX application using OCI-based Helm charts, customize deployments using values.yaml, perform Helm upgrades, manage Kubernetes services with NodePort, view Helm release history, perform rollbacks, and uninstall applications cleanly from a Kubernetes cluster. This Helm tutorial is designed for DevOps engineers, Kubernetes administrators, Linux administrators, cloud engineers, and beginners preparing for Kubernetes and DevOps interviews or certifications like CKA and CKAD. By the end of this video, you’ll understand how Helm simplifies Kubernetes application deployment and lifecycle management compared to manually handling large YAML manifests.

🔥 In this video you’ll learn:
✔️ What Helm is and why it is used in Kubernetes
✔️ How to install Helm on Linux
✔️ OCI-based Helm charts explained
✔️ Deploy NGINX on Kubernetes using Helm
✔️ Understand Helm values.yaml configuration
✔️ Customize Kubernetes deployments using Helm
✔️ Upgrade Helm releases using custom values
✔️ Change Kubernetes Service from LoadBalancer to NodePort
✔️ Access Kubernetes applications externally using NodePort
