Wrote a Containers/Kubernetes course
Over the last 5 years with a colleague, I have been co-creating and co-maintaining a Containers/Kubernetes course, which now spans 5 days.

This course uses the DevOps Stack (https://devops-stack.io) as a base to deploy the underlying Kubernetes platform on AWS EKS.
The Developer version of the course uses a sample app with 3 versions of the backend (in Java, Python, and Go), which students get to improve/instrument as they adapt it to deploy it as containers.
