There is a small cluster template created for 1.21, as well as 1.22 (T325538) though magnum requires the node flavor be set on the template level. As a result we will likely want a separate template for PAWS than for generic clusters, as PAWS will use a somewhat larger node. This ticket is for tracking of the creation of a k8s 1.21 template with larger worker nodes with PAWS as the subject.
