This is a simple controller to demonstrate how to interact within kubernetes using python api and custom resource definitions

• a running kubernetes/openshift cluster

on minikub/gce

kubectl run samplecontroller --image=karmab/samplecontroller --restart=Always
kubectl run sampleui --image=karmab/sampleui
kubectl expose deployment sampleui --port=9000 --target-port=9000 --type=LoadBalancer

• on openshift ( enough privileges needed as i m checking guitars cluster wide)

oc new-project guitarcenter
oc adm policy add-cluster-role-to-user cluster-admin -z default -n guitarcenter
oc new-app karmab/samplecontroller

Note that the guitar custom resource definition gets created when launching the controller

Create some guitars and see the review made for you

oc create -f crd/stratocaster.yml
oc create -f crd/lespaul.yml
oc get guitars -o yaml

To ease testing, you can also use the provided UI to list, create and delete guitars

oc new-app karmab/sampleui
oc expose svc sampleui

You can also have a look at initializer for extra code around Initializers

Also, if you prefer to use kopf, you can use the code in kopf_handler.py
