An experimental CLI which runs a long-running container, then prints out its logs.
This could be easier than remembering the syntax for kubectl run for when you want to debug a service using curl - or just to run a long-running batch-job, getting the result at the end.
lavoro uses the Kubernetes API and Go client to schedule a Kubernetes job.
Future work would include the use of informers and caches for efficiency.
