The Todo application is a simple microservice based application comprised of a ReactJS UI, a node Users API and a Java TodoItem API. For a database, mongodb is leveraged. We will use this application to learn about many of the core K8S concepts.
This is a good exercise to understand what is required to manually deploy a micro-service based application to Kubernetes. See manual-k8s-deploy/README.md
As your applications become more complex, you will quickly realize that you will need Helm to package your applications. See helm/README.md
