Coverage was checked with a cover profile. The biggest remaining gap is for
isSchedulableAfterClaimParametersChange and
isSchedulableAfterClassParametersChange which will get handled when refactoring
the
foreachPodResourceClaim (https://github.com/kubernetes/kubernetes/issues/123697).
* Don't evaluate extra nodes if there's no score plugin defined
* Fix existing unit test (add no op scoring plugin)
* Add unit tests for no score plugin scenario
* address review comments
* add a test with non-filter, non-scoring extender
Instead of modifying the PodSchedulingContext and then creating or updating it,
now the required changes (selected node, potential nodes) are tracked and the
actual input for an API call is created if (and only if) needed at the end.
This makes the code easier to read and change. In particular, replacing the
Update call with Patch or Apply is easy.
PVC and containers shared the same ResourceRequirements struct to define their
API. When resource claims were added, that struct got extended, which
accidentally also changed the PVC API. To avoid such a mistake from happening
again, PVC now uses its own VolumeResourceRequirements struct.
The `Claims` field gets removed because risk of breaking someone is low:
theoretically, YAML files which have a claims field for volumes now
get rejected when validating against the OpenAPI. Such files
have never made sense and should be fixed.
Code that uses the struct definitions needs to be updated.
The name "PodScheduling" was unusual because in contrast to most other names,
it was impossible to put an article in front of it. Now PodSchedulingContext is
used instead.
* allow preScore to return skip status to skip running the corresponding score extension
* add test case for all skipped
* add test case for select host
* update plugin status
* skip score when all plugins are skipped
* update
Tests scheduler enforcement of the ReadWriteOncePod PVC access mode.
- Creates a pod using a PVC with ReadWriteOncePod
- Creates a second pod using the same PVC
- Observes the second pod fails to schedule because PVC is in-use
- Deletes the first pod
- Observes the second pod successfully schedules

Move to use testing PodWrapper where applicable to
reduce duplicating pod creation code and shorten
number of lines.
Adding additional wrapper functions in PodWrapper
to ensure it covers all pod spec under tests.
