This will pull the necessary images from dockerhub and run the application.

Running the application with Ansible playbook in a Vagrant Virtual Machine

Prerequisites

• Vagrant
• VirtualBox

Start VM

Run the following command to get everything setup and started in the VM.

vagrant up

This will create a virtual machine, and get everything setup. When it's done, the application should now be up and accessed in the web browser:

http://localhost:3000

Running the application in Kubernetes container

The application is running on http://41.212.75.76:3000

Create a cluster

gcloud container cluster create-auto yolo-cluster --region us-central1

Apply the configurations

Navigate to /manifests dir ``cd manifests```

kubectl apply -f mongo_statefulset.yml
kubectl apply -f mongo_service.yml
kubectl apply -f backend_deployment.yml
kubectl apply -f backend_service.yml
kubectl apply -f client_deployment.yml
kubectl apply -f client_service.yml

After that, we can now access the application from the provided url
