There are two yamls with examples of deployment for Spring boot image in HA-CEP. See folder springboot/kubernetes

• deployment.yaml - use image quickstarter/openshift-kie-springboot:latest
• deployment_registry.yaml - according to git history this deployment is for debugging purposes and use following image <user>/openshift-kie-springboot:<version>

However, both images are almost identical. The only difference is in image and in the second yaml the service account is missing. I consider missing service account as a bug because it is not possible to access the config map without it and therefore leadership mechanism will not work.
