Enable AttachVolumeLimit feature

ddebroy · 2018-09-28T18:33:59Z

pkg/volume/csi/nodeinfomanager/nodeinfomanager_test.go

+			attachKey := v1.ResourceName(util.GetCSIAttachLimitKey(tc.driverName))
+			attachLimit := volumeLimits[attachKey]
+			if attachLimit != tc.expectedVolumeLimit {
+				t.Errorf("expected volume limit to be %d got %d", tc.inputVolumeLimit, attachLimit)


The log message is incorrect - expected volume limit is tc.expectedVolumeLimit not tc.inputVolumeLimit

good catch.

msau42 · 2018-09-28T22:57:22Z

Can we also add an e2e test? I don't know if this is something that unit tests would have caught.

Could you add a testcase for deletion against a node that previously doesn't contain attach limit info?

Now that we run the test in all cases, I think this should be covered by that

Could you add a test case with pre-existing attach limit on the node?

nit: Is it possible to have the logic below run for every test case, and have getVolumeLimits() return 0 if the attachKey doesn't exist? IMO, intuitively setting inputVolumeLimit in a test case means this value is passed into the method being tested as an input, whereas RemoveInfo doesn't depend on that param.

thanks for addressing!
/kind bug

Also add tests for it.

gnufied · 2018-10-01T18:40:59Z

@msau42 @verult fixed. Also added a small e2e to make sure node has limits. PTAL

msau42 · 2018-10-01T18:43:28Z

test/e2e/storage/volume_limits.go

+		if len(nodeList.Items) == 0 {
+			framework.Failf("Unable to find ready and schedulable Node")
+		}
+		node := nodeList.Items[0]


test description says that it checks all nodes, but we're only checking one.

should the test check all nodes?

msau42 · 2018-10-01T18:45:15Z

test/e2e/storage/volume_limits.go

+		volumeLimits := getVolumeLimit(&node)
+		if len(volumeLimits) == 0 {
+			framework.Failf("Expected volume limits to be set")
+		}


can we also launch a pod that uses the entire volume limit? You could potentially reuse this test case and just set a different numVolumes: https://sourcegraph.com/github.com/kubernetes/kubernetes/-/blob/test/e2e/storage/persistent_volumes.go#L319

We could but for gce - it appears that the limit on the selected node starts at 64. So, we will have to create a pod with 64+ volumes

64 1gi volumes should be within our quota...

okay, I think that will also make this test serial because no other workload(guess just with volumes but we don't have that level of granularity) can be scheduled on the node while this test runs on it. I can do that as a follow up PR while fixing #68912

Just for the record, as I can't /lgtm:

I went through the code and it seems OK to me; and the unit test seems to have good coverage as well. +1 for another test case that extrapolates the volume limit.
