Course Description

Kubernetes for Developers is a practical ebook course designed to help you deploy, scale, and operate modern cloud native applications with confidence. Built for the needs of software engineers working in Information Technology and Web Servers and Cloud Computing, it bridges the gap between writing code and running reliable services in real environments.

You will learn how to package and ship applications as Kubernetes workloads, define clear runtime boundaries when containerizing services, and connect components through service networking. As you progress, you will strengthen production delivery skills with ingress routing, TLS termination, and hardened external access, along with configuration and secret management that fits development, staging, and production workflows.

The course guides you through safer release strategies, resource management, scheduling controls, and reliability guardrails so your deployments remain stable under change. You will author reusable Helm charts to standardize application packaging, then adopt GitOps delivery with declarative deployments, automated rollbacks, and a CI to GitOps workflow that supports continuous delivery without losing control.

Operations and performance are a core focus. You will explore autoscaling fundamentals with HPA and VPA, secure cluster usage with namespaces, RBAC, and network policies, and build a strong observability foundation across logs, metrics, and tracing. You will also work with Prometheus and Grafana for monitoring and alerting basics, while developing troubleshooting playbooks for common Kubernetes failure scenarios and creating operational checklists for production readiness and incident response.

Hands-on mini projects bring everything together by deploying a REST API, worker, and database, adding ingress and certificates, implementing a GitOps pipeline for safe releases, and creating dashboards, alerts, and on call runbooks that match real team workflows. Start the course today and turn Kubernetes, Helm, GitOps, and observability into everyday developer skills.
