Create Ansible playbook to configure Minikube and deploy our simple image

[robcharlwood]

Story

As an Engineer, I want to create an ansible playbook that can be used to provision a minikube instance and deploy our super-duper-minikuber docker image to it with load balancing.

Out of scope

• Ingress
• Helm Tiller (though I may look to integrate this in a later ticket if I have enough time)
• SSL - This is just a simple hello world open source project and not intended for production use.

Acceptance Criteria

• New /health endpoint added for liveness and readiness probes.
• minikube cluster configured with a namespace specifically for the web app to run under
• App should be installed into the project namespace and not to the default namespace
• App should be load balanced across 4 replicas
• Deployment should have a readiness and liveness probe configured
• Liveness and Readiness probe should run against a new /health/ endpoint.
• Deployment should just pull the latest tagged version of the image from docker hub
• Deployment should run upgrades with rolling updates
• Deployment should pass the IP address of the pod on to the app as an env vars so that we can see load balancing working when it's running.
• Service should use the LoadBalancer type
• App label for selectors etc should be helloworld
