About the free ebook with audio
Kubernetes for Developers: Deploy, Scale, and Operate Modern Apps
This free ebook gives developers a practical path to running cloud-native applications on Kubernetes. Learn how to move from containerized services to reliable workloads that can be deployed, exposed, secured, monitored, and operated in real environments.
Build deployable application platforms
Explore Kubernetes workload packaging, service networking, Ingress routing, TLS termination, configuration, and secret handling. The ebook explains how application runtime boundaries and resource settings influence reliability, scheduling, and day-to-day operations.
Deliver changes safely
Use Helm to create reusable application packages and manage environment-specific values across development, staging, and production. Learn release strategies, declarative GitOps workflows, automated rollback concepts, and practical controls for safer continuous delivery.
Operate with confidence
Understand autoscaling with HPA and VPA, namespace and RBAC usage, network policies, and observability fundamentals. Coverage of logs, metrics, tracing, Prometheus, Grafana, alerts, and troubleshooting helps you diagnose common Kubernetes failures efficiently.
Apply the workflow end to end
Hands-on mini-projects connect the concepts by deploying a REST API, worker, and database; hardening external access with certificates; building a CI-to-GitOps delivery flow; and creating dashboards, alerts, and on-call runbooks. Finish with production-readiness and incident-response checklists for more dependable application operations.
How does Helm help package Kubernetes applications?
Helm packages Kubernetes manifests into reusable charts with configurable values for different environments.
What is GitOps in a Kubernetes delivery workflow?
GitOps uses version-controlled declarative configuration to synchronize cluster state and support auditable rollbacks.
Which observability tools does the ebook cover?
It introduces logs, metrics, tracing, Prometheus, Grafana, alerting, dashboards, and operational runbooks.
