Now you are confident, you slide the user-story to completed and tell all and sundry “well at least when you’re crappy code gets…

What this does is schedule Pods (which have a special annotation) to a farm of servers which are willing to accept ‘foreign’ containers (Pods). This means your Kubernetes master delegates…
