type AWSCloudConfig 

type AWSCloudConfig struct {
	Global struct {
		// TODO: Is there any use for this?  We can get it from the instance metadata service
		// Maybe if we're not running on AWS, e.g. bootstrap; for now it is not very useful
		Zone string

		KubernetesClusterTag string
	}
}

type AWSMetadata added in v0.15.0 

type AWSMetadata interface {
