Why'd you run them in kubernetes? Seems like extreme overkill for launching a short lived container for an integration test. What could kubernetes possibly add to that?
We also want homogeneity in tech when possible (we already heavily use kubernetes, we don't want to keep docker hosts anymore).
Teams of testers need to be accounted in terms of resource quotas and RBAC.
What exactly do you see as an overkill in wanting to run short-lived containers in kubernetes rather than in docker (if we already have kubernetes and "cook" it ourselves)?
