with the new SDK you would be able to parse your K8s manifests, and create (dynamic) configs with the parsed info. This is actually an interesting usecase, tnx!
Could you explain what you mean with "running a single job across multiple machines"? How would that exactly work clustering- and result-agreggation wise? Of course it's perfectly possible to run parallel jobs over multiple machines (https://circleci.com/docs/2.0/parallelism-faster-jobs/) but i guess you mean something different?
