Allow ImmediateBinding annotation when using populators #2765

ShellyKa13 · 2023-06-21T13:41:19Z

In case of using PVC with populators if the PVC has this annotation we prevent from waiting for it to be schedueled and we proceed with the process.
When using datavolumes with populators in case the dv has the annotation it will be passed to the PVC. we prevent from being in pendingPopulation in case the created pvc has the annotaion.
Plus when having honorWaitForFirstConsumer feature gate disabled we will put on the target PVC the immediateBinding annotation. Now we allow to use populators when having the annotation the the feature gate disabled.

What this PR does / why we need it:

Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged):
Fixes #

Special notes for your reviewer:
Integration of clone datavolumes with populators is in a PR: #2750
once merged will need to add to the datavolume clone controller the ImmediateBinding annotation in case of honorWaitForFirstConsumer feature gate disabled

Release note:

Allow ImmediateBinding annotation when using populators

Maybe put this code in a function that can be shared all the other controllers?

alromeros

The code looks good to me, do you plan to add more functional tests?

mhenriks · 2023-06-23T14:19:14Z

tests/datavolume_test.go

+				expectedPVCPhase = v1.ClaimPending
+			}
+			By(fmt.Sprintf("waiting for pvc to match phase %s", string(expectedPVCPhase)))
+			err = utils.WaitForPersistentVolumeClaimPhase(f.K8sClient, pvc.Namespace, expectedPVCPhase, pvc.Name)


I get that these existing DataVolume tests are implicitly testing "immediate bind on populators". May be helpful to have a couple explicit tests as well

@mhenriks @alromeros added functional test for import and upload for populators with pvc only, any other test you expected?

This should not be necessary. The prep phase can bind pvc' to a random node.

you mean leave without the fallback and create the pvc' without waiting for selected node and it will just get bound with the pod of the clone? or need to implement something for that?

Yeah shouldn't have to make any changes to the planner

I think this might be a real failure, if you look at the 1_dv logs file, you will see the DV in state pending while we are waiting for the WFFC or population pending state.

Yeah I think this is the same one I am handling in #2784

ShellyKa13 · 2023-07-10T11:55:46Z

@awels yeah :) never mind, I did the cherry pick so if we decide that its ok we can get the backport in faster and do the release.
But we will talk in grooming and see if we should create a fixup PR
