Hi Tom, Actually Stratos does not manage the k8 cluster. When using Stratos with k8 you just need to provide the k8 end points as in [1]. When you deploy an app, Stratos will talk to the k8 api and it will create pods in the k8 cluster.
Yes, you should be able to run Stratos against multiple k8 clusters. Stratos and Iaases are decoupled and k8 can be run remotely. For an example if you deploy an app to run in k8, Stratos will talk to the k8 API and create pods. For the pods, you need to have the docker image. Docker image should include the python cartridge agent (PCA). PCA will listen to Activemq and handles all the life cycle events related to itself. And also it publishes health stats to CEP from time to time. Only concern is if you run k8 remotely or a vpc, Stratos should be able to talk to K8 API and PCA should be able to talk to CEP and Activemq. You can use Stratos to scale the k8 cluster as well. In this scenario, you need to create an application in Stratos for the k8 cluster. Based on the health stats received by the Stratos, k8 cluster will auto scale. Other applications deploy on Stratos can use the deployed k8 cluster. This is not tested at the moment but theoretically this can be done. One other concern is that if you do auto scale k8 cluster using Stratos, when scaling down it can't guarantee that there aren't any running pods within the selected k8 node. This depends on the auto scaling policy uses in Stratos. Please refer [2] for persistence volume mapping.
