type DeleteCluster

type DeleteCluster struct {
	ClusterName string
	Cloud       fi.Cloud
}

DeleteCluster implements deletion of cluster cloud resources The algorithm is pretty simple: it discovers all the resources it can (primary using tags), and then it repeatedly attempts to delete them all until they are all deleted. There are a few tweaks to that approach, like choosing a default ordering, but it is not much smarter. Cluster deletion is a fairly rare operation anyway, and also some dependencies are invisible (e.g. ELB dependencies).
