Comment 4 for bug 1908110

Just to elaborate on the issue, pods not having CPU and mem requests means k8s has no idea where to schedule pods, and tends to just schedule them all on one node. Until that is overloaded and reaches a "NotReady" state. Worth noting https://bugs.launchpad.net/juju/+bug/1919976 here ("Need a way to differentiate between resource limits and requests in kubernetes constraints"), which is related.
