Introduction to Kubernetes

Learn Kubernetes fundamentals: what it is, how it runs apps, and how its components work. Build a mental model of clusters, nodes, and Pods. By the end, you'll be able to define, run, inspect, and clean up basic workloads using core Kubernetes tools.

Go beyond individual Pods to manage applications declaratively with Deployments. This course shows how Deployments use labels and selectors to group Pods, and how they manage their lifecycle, scale replicas, and roll out new versions of your application.

Make applications accessible with Kubernetes Services. Learn how Services use label selectors to dynamically find Pods, expose apps internally with ClusterIP and externally with NodePort, configure port mappings between Services and containers, and enable automatic service discovery via DNS.

Manage application data with Kubernetes volumes. Learn temporary storage for Pod communication, persistent storage that survives Pod restarts, and how Kubernetes provisions and manages storage resources.
