This will create 3 VM running CentOS, two of them running the hateoas spring boot example, and one using HAProxy to balance load between the instances

To run this test is based on using Vagrant and Virtualbox

just run:

vagrant up

For accessing to the Load Balancer just point the browser to:

https://192.168.15.20/customers

the SSL certificate is autogenerated so trust any warning message on the browser

For accessing to the individual hateoas services point the browser to

http://192.168.15.21:9000/customers

or

http://192.168.15.22:9000/customers

To shutdown this environment:

vagrant destroy

Kubernetes Deployment

This can also be set inside a Kubernetes cluster (Tested on GCP) by running this commands with a kubectl environment already defined:

cd k8s
kubectl -f k8s-rs.yml create
kubectl -f k8s-svc.yml create
kubectl -f k8s-haproxy.yml create
kubectl -f k8s-lb.yml create

check all the pods are up and running

kubectl get pods

To know which IP to connect, check for the External IP using

kubectl get svc haproxy-lb

https://EXTERNALIP/customers
