Deploying the cluster

To deploy the cluster with all the resources we configured before, run

kops create -f cluster.yaml
kops update cluster --name $CLUSTER_NAME --yes

The cluster is starting. It should be ready in a few minutes. Wait some minutes, and you can get the kubeconfig credentials:

kops export kubeconfig --admin --state $KOPS_STATE_STORE --name=$CLUSTER_NAME

Also, you can watch the process of deploying the cluster:

kops validate cluster --wait 10m
