I'm trying to get online-auction-scala running on GCP. The only thing I miss now is getting ingress working. The health check from search service reports UNHEALTHY status, although search service is up and running and there are no errors in it's logs.

The steps I do after building docker images and publishing them to docker registry:

gcloud container clusters create mt-develop
gcloud container clusters get-credentials mt-develop
kubectl create serviceaccount tiller --namespace kube-system
kubectl create clusterrolebinding tiller --clusterrole cluster-admin --serviceaccount=kube-system:tiller
helm init --service-account tiller
helm install lightbend-helm-charts/reactive-sandbox --name reactive-sandbox
PRIMARY_ACCOUNT=$(gcloud info --format='value(config.account)')
kubectl create clusterrolebinding cluster-admin-binding --clusterrole=cluster-admin --user=$PRIMARY_ACCOUNT
kubectl apply -f RBAC.yml

when the reactive-sandbox is ready, I'm running the script from KUBERNATES.md file.

Any help would be much appreciated.
