terraform apply
Important: You will need to delete/move elsewhere terraform state if you are booting production cluster after staging one (or vice versa). Otherwise terraform will think you want to rename/update variables
Export following following environment variables to deploy production cluster
export TF_cluster_name=datahub-production # Kuberntes Cluster Name (default: datahub-staging)
export TF_load_balancer_ip=35.224.172.105 # External IP of loadbalancer (default: 35.225.241.192)
export TF_node_pool_name=prodcution-node-pool # Node pool name (default: staging-node-pool)
Other configurable variables
export TF_region # The region to host the cluster (default: us-central1)
export TF_region # The zone to host the cluster (default: us-central1-a)
export TF_kubernetes_version # Kberntes version (default: 1.16.13-gke.1)
