Deploy Feature Branches to Kubernetes

Let's walkthrough a demo and GitHub Workflows YAML pipeline, where every push to a feat/* branch creates a new deployment with its own URL. We'll also look at strategies for tagging your containers and considerations for Kubernetes namespaces and security. This video is a relatively simple example of how to achieve dynamic environments and is most appropriate for use cases with single tenant Kubernetes clusters.
