You must have a local Kubernetes config file that is used by kubectl to access cluster(s).

Conventionally, the config file is called config (YAML) and is found in ${HOME}/.kube/config.

Google provides a way to generate a config file (and context) for you. To do this run gcloud container clusters get-credentials .... You'll need to fill in the blanks of the cluster name and probably the project, zone/region etc.:

gcloud container clusters get-credentials ${CLUSTER_NAME} \
--project=${PROJECT} \
--region=${REGION}

After running this command, you should be able to more ${HOME}/.kube/config and you should be able to access the cluster using e.g. kubectl get nodes.
