What you'll learn

• Containerise any application with clean, efficient Dockerfiles
• Run multi-container apps locally with Docker Compose
• Understand the Kubernetes architecture and what each component actually does
• Deploy, scale, and self-heal workloads with Pods, Deployments, and Services
• Expose applications properly with Services and Ingress
• Package and ship apps to a cluster with Helm, following real deployment practices

About this course

Containers changed how software ships, and Docker plus Kubernetes are the skills nearly every backend, DevOps, and platform role now expects. This course takes you from your first container to deploying a real application on a Kubernetes cluster — building genuine understanding at each step, not just commands to copy. You'll start with Docker: images, layers, writing clean Dockerfiles, and orchestrating multi-container apps locally with Compose. Then you'll move to Kubernetes and — importantly — understand *why* it exists and how its pieces fit: the control plane, Pods, Deployments, and the declarative model that gives you self-healing and scaling. You'll expose apps with Services and Ingress, manage configuration and secrets, and package everything with Helm the way teams do in production. Throughout, you deploy a real application so the concepts stick. You should be comfortable on the command line and with a web app's basic structure. By the end you'll be able to containerise, orchestrate, and deploy applications with confidence — and speak fluently about it in interviews.
