Multiverse Project-2

• This application registers and stores a User's information to generate a credit card. This application was created using Kotlin, Spring-Boot, Cassandra, Docker, and Kubernetes.
• This application can run in Docker or Kubernetes

Getting Started

Docker

1. To run in Docker, cd into root directory and run 'docker-compose up'
2. This command will create the spring boot app image and pull the cassandra latest image from docker hub.

• CASSANDRA_BROADCAST_ADDRESS environment variable may need to be changed to run both the spring application and cassandra docker containers.

• To run only the cassandra docker container, run 'docker-compose up' and stop the spring boot app or comment out the spring boot app in docker-compose.yaml

Kubernetes

1. To run in Kubernetes, use minikube as your kubernetes cluster and run 'minikube start'.
2. Load 'cassandra:latest' image into minikube cluster by following this tutorial.
3. Run these commands:

   kubectl create -f cassandra-service.yaml
   kubectl create -f local-volumes.yaml
   kubectl create -f cassandra-statefulset.yaml
   minikube dashboard
   kubectl exec -it cassandra-0 cqlsh
   create keyspace user_registration with replication = {'class':'SimpleStrategy', 'replication_factor':1};
   create table User(username VARCHAR, firstName VARCHAR, lastName VARCHAR, email VARCHAR, password VARCHAR, role VARCHAR, creditCard VARCHAR, primary key(username, email));
   SELECT * FROM USER;
   kubectl port-forward statefulset/cassandra 9042:9042
