Duration 5 days – 35 hrs
Overview
This hands-on training course introduces developers to containerization and orchestration tools Docker, Kubernetes, and OpenShift that are essential for developing scalable, portable, and resilient applications. The course covers key concepts, commands, workflows, and best practices to enable developers to containerize applications, deploy them in clusters, and manage their lifecycle using open-source and enterprise-grade tools. To provide a solid foundation for developers in effectively using Docker, Kubernetes, and OpenShift to build, deploy, manage, and scale containerized applications in modern development environments.
