curl -X POST http://localhost:3000/movies -d @data.json

Minikube (k8s)

• minikube semi-task profile is required

minikube config set memory 4092
minikube start -p semi-task --nodes 2
minikube addons enable ingress -p semi-task
echo $(minikube ip -p semi-task) semi-task.local | sudo tee -a /etc/hosts 
cat /etc/hosts

Deploy to minikube semi-task

• kube config path ~/.kube/config is required
• kube context is required to be semi-task

cd terraform

Notes

• For docker compose .env file supplies the password used to intiate the root and app databases
• For minikube-terraform the random provider is used to create the passwords, then handled by the helm provider
• Helm charts are at /charts one for the application and for the database

Potential Improvements

• Support replication for mongodb.
• Retry logic on app db connect and ping
• Terraform hard-coded contexts and config paths
