Make PV tests work on kubemark clusters

Open mm4tt opened this issue 6 years ago • 11 comments

Enabling PVs in the load test failed the kubemark presubmit because scheduler failed to schedule pods with PVs

Unable to schedule test-y6u59n-1/small-statefulset-0-0: no fit: 0/101 nodes are available: 1 node(s) were unschedulable, 100 node(s) had volume node affinity conflict.; waiting

In order to make it work on kubemark we'll most likely have to change a few places in the code (or ensure they already work this way) so they're faking operations related to attaching and mounting PDs in kubemark

  • Attach Detach Controller
  • HollowKubelet
  • Scheduler
  • ?

I'd like to pick this up, where would I begin?

Hey, @Jukie, that's great to hear!

This one is a bit more complicated, I'll need to think about it more and come up with a more concrete list of steps. Unfortunately, I won't have time to do it until ~mid next week. In the meantime, feel free to pick another issue from the help wanted list. I think https://github.com/kubernetes/perf-tests/issues/595 is relatively simple and will get you through all the prep work required to start contributing to kubernetes (forking repos, signing CLA, etc.).
