 To deploy kubespray on [AWS](https://aws.amazon.com/) uncomment the `cloud_provider` option in `group_vars/all.yml` and set it to `'aws'`. Refer to the [Kubespray Configuration](#kubespray-configuration) for customizing the provider.
 
 Prior to creating your instances, you **must** ensure that you have created IAM roles and policies for both "kubernetes-master" and "kubernetes-node". You can find the IAM policies [here](https://github.com/kubernetes-sigs/kubespray/tree/master/contrib/aws_iam/). See the [IAM Documentation](https://aws.amazon.com/documentation/iam/) if guidance is needed on how to set these up. When you bring your instances online, associate them with the respective IAM role. Nodes that are only to be used for Etcd do not need a role.

 ## Provisioning
 
 You can deploy instances in your cloud environment in several ways. Examples include Terraform, Ansible (ec2 and gce modules), and manual creation.
