Install Helm into your Kubernetes cluster, and configure it to be able to find service-catalog:
helm init
helm repo add svc-cat https://svc-catalog-charts.storage.googleapis.com
Grant Helm permission to admin your cluster, so it can install service-catalog:
kubectl create clusterrolebinding tiller-cluster-admin \
--clusterrole=cluster-admin \
--serviceaccount=kube-system:default
Install service-catalog:
helm install svc-cat/catalog --version 0.1.29 --name catalog --namespace catalog
More detailed instructions for installing service-catalog can be found in the service-catalog github repo here.
