Free course on freeCodeCamp
freeCodeCamp's Kubernetes Course teaches Kubernetes, the container orchestration platform for managing Docker containers at scale. You learn pods, services, deployments, and how to manage applications across multiple servers. The course is free on freeCodeCamp.org. After finishing, you understand Kubernetes architecture and can deploy containerized applications. Kubernetes is the industry standard for production container orchestration, used by most large organizations. The main limitation: Kubernetes is complex. This course is a foundation; mastery comes from deploying real applications and troubleshooting.
Production use of Kubernetes reached 80% of organizations running containers in 2024, up from 66% the year before (source: CNCF Annual Survey 2024, cncf.io/reports).
