Other modes

There are various other modes to take into consideration, including the following:

• Build a terraform model: --target=terraform. The terraform model will be built in out/terraform.
• Build a cloudformation model: --target=cloudformation. The Cloudformation JSON file will be built in out/cloudformation.
• Specify the K8s build to run: --kubernetes-version=1.2.2.
• Run nodes in multiple zones: --zones=us-east-1b,us-east-1c,us-east-1d.
• Run with a HA master: --master-zones=us-east-1b,us-east-1c,us-east-1d.
• Specify the number of nodes: --node-count=4.
• Specify the node size: --node-size=m4.large.
• Specify the master size: --master-size=m4.large.
• Override the default DNS zone: --dns-zone=<my.hosted.zone>.

Another tool for diagnosing the cluster status is the componentstatuses command, which will inform you of state of the major Kubernetes moving pieces:

$ kubectl get componentstatuses
NAME STATUS MESSAGE ERROR
scheduler Healthy ok
controller-manager Healthy ok
etcd-0 Healthy {"health": "true"}
