Docker images and containers you can explain line by line, then Kubernetes enough to deploy, scale and debug a workload without folklore.

7h 30mProject-basedfreeCodeCamp.org7h 30m
Seven and a half hours, published late 2025, that carry an application from Dockerfile to registry to deployment with multi-stage builds and Compose. The modern follow-on to the introductory course.
5h 53mLearnPath pickfreeCodeCamp.org5h 53m
A six-hour 2025 course that deploys a real application to Kubernetes across local clusters and a managed cloud cluster: pods, deployments, services, ingress, configuration and autoscaling, in the order you meet them in production.
2h 46mBest for beginnersTechWorld with Nana2h 46m
Three hours that explain images, containers, volumes, networking and Compose with animated diagrams and then demonstrate each one. The mental model first approach is why this remains the reference Docker introduction.
3h 37mBest for beginnersTechWorld with Nana3h 37m
Three and a half hours built on clear diagrams of the control plane and worker nodes, then hands-on with kubectl. The gentle introduction that makes the longer courses feel obvious.
6h 15mAdvancedDevOps Directive6h 15m
Beyond the beginner path: stateful workloads, network policies, RBAC, operators and cluster upgrades, with a real application carried through. For engineers who already deploy to Kubernetes and keep meeting the same walls.
1h 3mTechWorld with Nana1h 3m
A focused hour on Compose: services, networks, volumes, environment handling and the file structure that keeps multi-container projects sane.
