# IMPORTANT:
#
# This CI/CD will run on an Ubuntu VM. After this script runs, the VM will retain the state.
# It's your responsibility to clean the VM up in the cleanup stage after job finishes executing.
# This script runs on Minikube. since our deployments are on Kubernetes, our aim is to create EXACT same replica for test, staging and production.
