DATABASE:
MongoDb => Each service has their own copy of mogodb database

HOW TO RUN THE APPLICATION:

USING KUBERNETES:
=> skaffold.yaml and infra directory is specifically for kubernetes only
=> start k8s cluster
=> RUN below command to generate secrets in the cluster
=> kubectl create secret generic jwt-secret --from-literal=JWT_KEY=someRANDOMjwtKEY
=> kubectl create secret generic stripe-secret --from-literal STRIPE_KEY=yourstripesecretkey
=> RUN skaffold dev which will create docker images and eventually run the kubernetes deployments files that is inside the infra directory.
=> In case of client(NEXTJS) inside file api/build-client.js set the url.server value to ingress-nginx controller
=> finally, go to your k8s cluster ip in the browser

USING DOCKER COMPOSE:
=> docker-compose.yml and reverse_proxy directory is specifically for docker compose only
=> RUN docker-compose -f up\ => above command will create docker images and eventually run those in container.
=> finally, go to your localhost:80 in your browser.

NOTE:
=> for payment service provide STRIPE_SECRET_KEY env variable
=> also add NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY env variable to NEXTJS .env.local file
