Unresponsive SonarQube in Kubernetes - docker

Question

We're creating a kubernetes deployment for sonar. When using the embedded H2 DB the deployment works fine and SonarQube is available thru the kube Ingress controller.
But when setting JDBC parameters for persistence the SonarQube instance fails to respond to any request and outputs the following error (in logs)
01:31:51.000 (unknown):0 warning: already initialized constant Input
01:31:51.000 WARNING: while creating new bindings for class org.jruby.rack.RackInput,
01:31:51.000 found an existing binding; you may want to run a clean build.
Here's the Kubernetes deployment descriptor:
apiVersion: extensions/v1beta1
kind: Deployment

Deployments is experiment feature for the kubernetes. Use replicationcontroller here is my configuration. It's work in production.
apiVersion: v1
kind: ReplicationController
