gcloud container clusters create private-cluster-1 \
    --create-subnetwork name=my-subnet-1 \
    --enable-master-authorized-networks \
    --enable-ip-alias \
    --enable-private-nodes \
    --master-authorized-networks="$(curl -s https://icanhazip.com/)/32" \
    --master-ipv4-cidr 172.16.0.0/28 \
    --machine-type=n2-standard-2 --max-nodes=3 --min-nodes=1
