Progressing=Trueduring the rollout delete/create gap.When a no-surge DaemonSet rollout deletes an old pod before its replacement is scheduled, the status can contain
DesiredNumberScheduled=6,CurrentNumberScheduled=5, andUpdatedNumberScheduled=5. The controller can also setObservedGenerationtoGenerationbefore the replacement is scheduled.isDaemonSetRollingOutthen returnsfalse, so both callers suppress the progressing message while the rollout is incomplete. Kubernetes defines these counters and performs this status update ordering in the DaemonSet controller. (raw.githubusercontent.com)Use a rollout signal that remains active until all desired nodes have updated pods. Do not replace this comparison with
UpdatedNumberScheduled < DesiredNumberScheduledalone, because that would restore the scale-up false positive.Verification script

Inline comments:
In `@Dockerfile`:
- Line 9: Replace the broad COPY instruction in the test-extension builder stage
of Dockerfile with explicit COPY entries covering only the extension module and
its required local replacement paths. Apply the same change at
Dockerfile.rhel7:9-9; both sites require direct updates, and no other
build-context files should be copied.
In `@test/tests-extension/README.md`:
- Around line 29-41: Update the “How to Run” instructions in the README to
explicitly establish test/tests-extension as the working directory before
running make build and the cluster-dns-operator-tests-ext commands, or use
equivalent directory-qualified commands so the documented paths resolve
correctly from any starting location.
In `@test/tests-extension/test/e2e/bindata.mk`:
- Around line 13-14: Update the bindata generation command in the Makefile so
its inputs include only fixture assets, excluding the generated bindata.go
output and helper .go files under TESTDATA_PATH. Preserve the existing package,
output, prefix, and generator options while preventing generated Go files from
being re-embedded.
In `@test/tests-extension/test/e2e/dns-operator.go`:
- Around line 21-54: Exclude both affected Ginkgo tests from MicroShift: add the
[Skipped:MicroShift] annotation to the monitoring-resource test identified by
its Author:mjoseph-Critical-26151-Integrate DNS operator metrics with Prometheus
description at test/tests-extension/test/e2e/dns-operator.go lines 21-54, and to
the ClusterOperator/CVO service-IP test at lines 59-108. No other behavior
changes are needed.
- Around line 237-261: Update the log-level checks in the test flow around
patchGlobalResourceAsAdmin to wait for the dns-operator rollout after each
Debug, Trace, and Normal patch, then verify the reconciled container arguments
or corresponding level-specific runtime logs rather than only DNS resource
fields. Retain the existing desired-state assertions and ensure each level’s
effective runtime behavior is validated before proceeding.
- Around line 66-72: Update the deferred cleanup around the DNS operator test to
capture and assert errors from CVO scaling, DNS operator scaling, and
deleteDnsOperatorToRestore, then verify the restored components become ready.
Also update the code at test/tests-extension/test/e2e/dns-operator.go lines
85-89 to capture and assert Service deletion and scale-up errors; ensure no Go
error returns are ignored.
In `@test/tests-extension/test/e2e/testdata/fixtures.go`:
- Around line 54-76: Update the fixture path setup around filepath.Walk and the
final os.Chmod calls to propagate every filesystem error: return each os.Chmod
error from the Walk callback, check the filepath.Walk result and fail
consistently, and handle errors from the final targetPath permission update
before returning the fixture path. Do not discard any error returns.
- Around line 16-25: Remove eager fixture-directory creation from init and
initialize it lazily in FixturePath on the first fixture request, preserving the
existing error handling and permissions setup; ensure commands that do not
request fixtures create no temporary directory.
