Summary

Adds support for loading OTE extension binaries directly from the local filesystem via the --extension-binaries CLI flag or EXTENSION_LOCAL_BINARIES environment variable.

Motivation

Per discussion in SHIP Slack thread (Sep 17), this addresses LP Interop use cases where the Step Container already contains both openshift-tests and extension binaries.

The current off-payload discovery mechanism (TestExtensionAdmission CRD + ImageStreamTag) requires:

  1. Installing CRD on the cluster under test
  2. Creating TestExtensionAdmission CR with permit patterns
  3. Creating annotated ImageStreamTags
  4. Ensuring cluster can pull extension images
  5. Running oc image extract to extract binaries

When binaries already exist on the local filesystem (e.g., /usr/bin/interop-tests-ext.gz), this discovery overhead is unnecessary.

Changes

  • Added --extension-binaries flag to run command
  • Added EXTENSION_LOCAL_BINARIES env var support (colon-separated paths)
  • Modified ExtractAllTestBinaries() to load from local paths before payload extraction
  • Handles gzipped binaries (.gz suffix)
  • Sets executable permissions (chmod 0755)
  • Updated all call sites to pass new parameter

Usage

Via CLI flag:

openshift-tests run-suite interop/cnv-odf \
  --extension-binaries /usr/bin/interop-tests-ext.gz

Via environment variable (multiple binaries):

EXTENSION_LOCAL_BINARIES=/usr/bin/test1.gz:/usr/bin/test2.gz \
openshift-tests run-suite interop/cnv-odf

Combined with tag override to skip payload extraction:

EXTENSION_LOCAL_BINARIES=/usr/bin/interop-tests-ext.gz \
EXTENSION_BINARY_OVERRIDE_INCLUDE_TAGS=none \
openshift-tests run-suite interop/cnv-odf

Benefits

  • ✅ Eliminates CRD/IST discovery complexity for local binaries
  • ✅ Reduces startup overhead (no oc image extract)
  • ✅ Simplifies Step Container design (composite image approach)
  • ✅ Maintains openshift-tests monitoring features (disruption tracking, alerts, cluster state)
  • ✅ Enables LP Interop to use openshift-tests orchestration without off-payload setup

Testing

Tested with local extension binary:

  • Binary loaded from filesystem
  • Gzip extraction working
  • Extension tests discovered and executed
  • Monitoring features active

Context

This was requested by @edo (MPIIT) on Sep 17 in #team-mpex-integrity-interop:

"@chaclark @amiskin Please submit a PR against openshift-tests to add the proposed CLI options. Proposing these changes directly will be much faster than waiting for the SHIP team to implement them."

@forrest (TRT) suggested AI-assisted implementation:

"If you put a card up for TRT we would likely ask Claude/Cursor/Codex/Chai to open the PR. So 2 asks: 1. Be as specific as you can in the card for what you need 2. Take a crack at it yourself with the AI/Agent of your choosing"

cc: @decarr @stbenjam @sosiouxme for TRT review


Note: This is part of INTEROP-9204 (LP Interop OTE integration) and addresses the "LP Interop integration mechanics" discussed in the Sep 17 SHIP thread.

Summary by CodeRabbit

  • New Features

    • Added support for loading extension test binaries directly from local filesystem paths.
    • Added an --extension-binaries option and corresponding environment variable configuration.
    • Local binaries are validated, prepared for execution, and included in test runs.
  • Bug Fixes

    • Preserved existing extraction, cleanup, error handling, and test-suite behavior when local binaries are not specified.

This adds support for loading OTE extension binaries directly from the
local filesystem via the --extension-binaries CLI flag or
EXTENSION_LOCAL_BINARIES environment variable.

Motivation:
For LP Interop use cases where the Step Container already contains both
openshift-tests and extension binaries, the current off-payload discovery
mechanism (TestExtensionAdmission CRD + ImageStreamTag) introduces
unnecessary overhead. This flag allows bypassing that discovery when
binaries are already present locally.

Changes:
- Added --extension-binaries flag to run command
- Added EXTENSION_LOCAL_BINARIES env var support
- Modified ExtractAllTestBinaries to load from local paths
- Updated all call sites to pass new parameter

Usage:
  openshift-tests run-suite interop/cnv-odf \
    --extension-binaries /usr/bin/interop-tests-ext.gz

Or via env var:
  EXTENSION_LOCAL_BINARIES=/usr/bin/test1.gz:/usr/bin/test2.gz \
  openshift-tests run-suite interop/cnv-odf

Benefits:
- Eliminates CRD/IST discovery complexity
- Reduces startup overhead (no oc image extract)
- Simplifies Step Container design
- Maintains openshift-tests monitoring features

Walkthrough

The extraction API now accepts colon-separated local extension binary paths. Ginkgo exposes the paths through a flag and environment variable. Other callers pass an empty value and retain their existing behavior.

Changes

Local extension binary loading

Layer / File(s) Summary
Local binary extraction
pkg/test/extensions/binary.go
ExtractAllTestBinaries validates configured local paths, decompresses them when needed, sets mode 0755, creates local TestBinary values, and appends them to the result.
Ginkgo local binary wiring
pkg/test/ginkgo/cmd_runsuite.go
GinkgoRunSuiteOptions adds LocalExtensionBinaries. The --extension-binaries flag uses EXTENSION_LOCAL_BINARIES as its default and passes the value to extraction.
Extraction caller updates
pkg/cmd/openshift-tests/images/images_command.go, pkg/cmd/openshift-tests/list/extensions.go, pkg/testsuites/standard_suites.go
Existing callers pass an empty local path value to the expanded extraction function. Their result handling remains unchanged.

Merge Risk: 🟠 High · up to d340d

The advertised local-binary workflow can still depend on payload infrastructure, and using a gzip binary can delete the supplied artifact. These issues should be fixed before merge.

pkg/test/extensions/binary.go:634-693
🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Make local-only selection explicit without dropping payload binaries.

--extension-binaries is documented to load local binaries without payload or non-payload extraction. However, ExtractAllTestBinaries returns before loading them when OPENSHIFT_SKIP_EXTERNAL_TESTS is set. Otherwise, it performs payload selection, provider setup, and admission discovery before returning the local binaries. This blocks local-only binary discovery without payload or cluster access.

Do not use a non-empty localBinaryPaths value as an unconditional early return. The function currently appends local binaries to the payload and permitted non-payload binaries, so that branch would drop payload binaries in additive mode. Add an explicit local-only mode that bypasses payload setup, and retain the existing append behavior when local and payload sources are selected together.

configured local .gz inputs into a managed temporary path rather than modifying
or deleting the configured source. Ensure the returned cleanup removes that
temporary decompressed file in addition to extracted provider files, while
preserving existing behavior for other input types.

non-empty --extension-binaries input when trimming and filtering tokens produces
no paths. Track whether any usable path was extracted, and return a validation
error for inputs such as ":" or whitespace before continuing to payload
binaries; preserve the existing behavior for valid paths and truly empty input.

Reject non-empty --extension-binaries input that normalizes to no paths.

ExtractAllTestBinaries trims each colon-separated token and skips empty tokens. Values such as ":" or whitespace therefore produce no local binaries without an error. The normal extraction path then continues with payload binaries, so the configured input can be silently ignored. Return a validation error when non-empty input produces no paths.

Do not modify the configured .gz source file.

ungzipFile receives the configured local path directly. For a .gz path, it writes to the path without .gz and then removes the configured source. The returned cleanup only owns extracted provider files, so the local decompressed file is not managed either.

Decompress local inputs into a managed temporary path, retain the configured source, and remove the temporary file through the returned cleanup.
