ZONE=us-central1-b
CLUSTER_VERSION=$(gcloud beta container get-server-config --zone ${ZONE} --format='value(validMasterVersions[0])')

gcloud container clusters create dev \
  --cluster-version ${CLUSTER_VERSION} \
  --machine-type n1-standard-4 \
  --num-nodes 3 \
  --scopes=cloud-platform \
  --zone ${ZONE}

Install metacontroller

  1. Install metacontroller:
kubectl create clusterrolebinding ${USER}-cluster-admin-binding --clusterrole=cluster-admin --user=$(gcloud config get-value account)

kubectl apply -f https://raw.githubusercontent.com/GoogleCloudPlatform/metacontroller/master/manifests/metacontroller-rbac.yaml
