Hm, parsing the Kubernetes manifests sounds like a lot of work, and wouldn't guarantee 1:1 correctness. Some Kubernetes things (secrets, mounted configmaps, and ingresses, for example) don't even have CircleCI equivalents.

By multiple machines I mean running apps (both our own, and also third-party software like databases) on multiple machines as part of the test. A single test may have to stand up too much for a single machine to handle.

The beauty of Kubernetes is that this just works: Kubernetes will "pack" the nodes however it likes, and you just need to specify your resource requirements.
