Overview

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.

Audience

System administrators and Devops professionals who want to understand and use Docker and Kubernetes in enterprise and cloud environments.

Thinking about Onsite?

If you need training for 3 or more people, you should ask us about onsite training. Putting aside the obvious location benefit, content can be customised to better meet your business objectives and more can be covered than in a public classroom. Its a cost effective option. One on one training can be delivered too, at reasonable rates.

Submit an enquiry from any page on this site and let us know you are interested in the requirements box, or simply mention it when we contact you.
