The Balancers load balance between PODs that are filtered by matching their selectors in the meta information and the Selector specified in the balancer description in the spec section . All nodes are connected to one common network, so you can connect to any node (I did this via SSH of the GCP WEB interface in the section with Compute Engine virtual machines). You can address both the IP address in the container or node host, and the host of the terraform-nodejs service in the terraform-NodeJS: 80 curl container , which is created by the internal DNS by the name of the service. You can view the external IP address EXTERNAL -IP both using kubectl at the service and using the web interface: GCP -> Kubernetes Engine -> Services:
