Preface

Kubernetes with CoreOS


Now that we understand the benefits, let's take a look at a Kubernetes cluster using CoreOS. The documentation supports a number of platforms, but one of the easiest to spin up is AWS with the CoreOS CloudFormation and CLI scripts.

Note

If you are interested in running Kubernetes with CoreOS on other platforms, you can find more details in the CoreOS documentation athttps://coreos.com/kubernetes/docs/latest/.https://coreos.com/kubernetes/docs/latest/We can find the latest instructions for AWS at https://coreos.com/kubernetes/docs/latest/kubernetes-on-aws.html.
