Kubernetes Tutorial for Beginners: Pods to Helm
Learn Kubernetes from zero: pods, deployments, services, ingress, storage, probes, autoscaling, RBAC and Helm, then deploy a real app in a lab.
What You'll Learn
Understanding Why Kubernetes Exists
Friday, 8:47 PM. Dinner rush. A food delivery app is pushing 3,000 orders a minute through 40 containers spread across 12 servers.
Understanding the Kubernetes Architecture
What is inside a Kubernetes cluster? A cluster is a group of machines, called nodes, that Kubernetes manages as one big computer.
Setting Up Your First Cluster and kubectl
Which local cluster should a beginner use?
Running Containers with Pods
What is a Pod and why not just a container?
Organizing Resources with Namespaces, Labels and Annotations
What are namespaces and when should you create them? A namespace is a named partition inside one cluster.
Deploying Applications with Deployments and Rollout Strategies
How do Deployments, ReplicaSets and Pods fit together? A Deployment is the standard way to run a stateless app.

Kubernetes feels hard because it has many objects, but most of them follow one idea: you describe what you want in YAML and Kubernetes keeps reality matching it. Learn Pods, Deployments and Services first, then add storage, config and scaling. With a local kind cluster you can practise everything for free.
You need to understand containers and images, and Docker is the easiest way to learn them. Kubernetes itself runs containers through containerd or CRI-O, but images built with Docker run on Kubernetes without changes. Tools like kind also use Docker to run a local cluster.
A container is one running process packaged from an image. A Pod is the Kubernetes wrapper around one or more containers that share an IP address, storage volumes and lifecycle. Kubernetes schedules and manages Pods, never bare containers.
Both are good. kind starts fast and can create multi-node clusters inside Docker, which makes scheduling, DaemonSets and taints easy to see. Minikube has convenient add-ons such as ingress and metrics-server. This module uses kind.
