Does anyone use Spinnaker for deployment of short running jobs, similar in spirit to what Kubernetes or Nomad do? If so, how do they do it? If not, are there any plans to support it one day?
The kubernetes provider specifically supports a Run Job stage in a pipeline that allows execution of a container that is expected to run to completion.
Similarly there is an option to run a jenkins job as a stage which I've seen teams use to execute arbitrary work (not just CI type of tasks)
