Note that this is the only cluster test to fail and this is also the only cluster test to make use of --sort-by. I suspect what is going on is that we've waited for the manager to running but we haven't guaranteed that the manager labeled the worker pods, or even ensured that the worker pods are running.

As this looks to be a test only issue I won't block the v0.1.0 release over this.

Seems to be introduced with #48
