Ephemeral instances can be launched on any cloud platform that supports our Deployment Providers.

Google Container Engine (GKE)

Google's Cloud Platform GKE (container engine) uses Kubernetes to manage containers cluster-wide.

In order to integrate Ephemerals with GKE, you will first need setup a new container cluster using a Google Cloud account. For more details on how to setup the cluster, refer to following instructions from Kubernetes documentation.

Once a container cluster is ready, we need to get details about its Kubernetes host and then initialize KubernetesDeploymentHandler with Kubernetes host details.

DeploymentHandler kubernetesDeploymentHandler = new KubernetesDeploymentHandler.Builder(
                new KubernetesService.Builder()
                        .withHost(KUBERNETES_HOST)
                        .withTrustCerts(KUBERNETES_TRUSTCERTS)
                        .withUsername(KUBERNETES_USERNAME)
                        .withPassword(KUBERNETES_PASSWORD)
                        .withNamespace(KUBERNETES_NAMESPACE)
                        .build())
                .build())

Kubernetes Service Types

More info about different service types in GCP: http://kubernetes.io/docs/user-guide/services/#publishing-services---service-types

###NodePort

By default, Ephemeral's Kubernetes Provider will use NodePort service type for exposing the deployment endpoint. In such case, you will need to add a firewall rule to access any NodePort endpoint by allowing outgoing traffic for NodePort range [default: 30000-32767].

###Load Balancer You can choose to use LoadBalancer service type by overriding the KubernetesDeploymentConfiguration service parameter instance:

new KubernetesDeploymentContext(
                    kubernetesDeploymentHandler
                    ,
                    new KubernetesDeploymentConfiguration.Builder()
                            .withServiceType(KubernetesServiceType.LOAD_BALANCER)
                            .build()))
                    .build());

No firewalls rules needed in LoadBalancer service type.

Ephemeral instances will now be deployed to Google's Container Engine cluster.
