To use, deploy services.yaml, and copy the LoadBalancer IP used to the axios request in k8s-react-demo/src/Hostname.tsx.
Build both k8s-react-demo and k8s-go-demo images, and push them to an image registry.
Modify the k8s-deploy.yaml in both directories to the new respective images.
Apply both deployments.
Scale the k8s-react-demo deployment, and check the changing hostname on the k8s-react-demo LoadBalancer IP.
