Local Development Setup

We initially started using minikube as the local development environment but we later realised that it adds an extra layer of complexity to our developers. Therefore we resorted to a setup powered by docker-compose.

Sample directory structure

kubeflex-platform
--auth-service
----Dockerfile
--frontend
----Dockerfile
--backend
----Dockerfile
--docker-compose.yaml

Sample content of docker-compose.yaml file

These exact environment variable keys are available in kubernetes in form of secrets (with different values of course)
