Chapter 2 ■ Kubernetes on CoreOS on AWS
Initializing the Cluster CloudFormation
Using the Amazon EC2 key pair, KMS Key ARN string, and external DNS name, initialize the CloudFormation
stack:
kube-aws init --cluster-name=kube-coreos-cluster
--external-dns-name=NOSQLSEARCH.COM
--region=us-east-1
--availability-zone=us-east-1c
--key-name=kubernetes-coreos
--kms-key-arn="arn:aws:kms:us-east-1:672593526685:key/b7209ba2-cb87-4ccf-8401-5c6fd4fb9f9b "
The CloudFormation stack assets are created; the main configuration file is cluster.yaml, as shown in
Figure 2-7.

Rendering Contents of the Asset Directory
Next, render (generate) the cluster assets (templates and credentials), which are used to create, update, and
interact with the Kubernetes cluster.
kube-aws render
The CloudFormation template stack-template.json is created (as shown in Figure 2-8); it will be used
to create the Kubernetes cluster. The cluster.yaml, userdata files for the Kubernetes controller and the
worker, and stack-template.json could optionally be customized.
