5 days. Hands on.
Containerisation has revolutionised the way organisations build, deploy, and operate solutions in the cloud and on-premise. Docker knowledge has become indispensable, and Kubernetes has quickly emerged as the de-facto standard way to manage and orchestrate Docker containers.
This course provides a thorough grounding in both Docker and Kubernetes. We explain how to create lean and mean containers and how to ensure they operate in a resilient and responsive fashion. We explain how to enforce best practices by applying the principles laid out in the Twelve Factor App methodology.
