If you haven't started with Kubernetes, or containers for that matter, then kick off 2020 by learning something new! First, this presentation will review the history and fundamental components of Kubernetes, providing information that novices and professionals can add on to their Kubernetes knowledge base. Second, a segment on getting started with Kubernetes, starting from scratch to deploying our applications in a development environment using Helm. Key takeaways: * Quick Kubernetes/container history and how it has gotten to where it is today * A dive into what makes up Kubernetes and its many components * Creating a managed cluster and demonstrating the practical use cases for it * Leveraging Helm to templatize our Kubernetes YAML and populate our cluster with services
