Conversation
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

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy liftMake local-only selection explicit without dropping payload binaries.
--extension-binariesis documented to load local binaries without payload or non-payload extraction. However,ExtractAllTestBinariesreturns before loading them whenOPENSHIFT_SKIP_EXTERNAL_TESTSis 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
localBinaryPathsvalue 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.🤖 Prompt for AI Agents

Addresses CodeRabbit review feedback: 1. Fix ungzip() issue (MAJOR): - Local .gz files now decompress to temp directory - Original source file preserved (was being deleted) - Temp files tracked and cleaned up properly - Fixes idempotency (can run tests multiple times) 2. Add input validation (MINOR): - Reject non-empty input that produces no valid paths - Error on inputs like ":" or whitespace - Helps catch typos and configuration errors 3. Add local-only mode (MAJOR): - New EXTENSION_LOCAL_BINARIES_ONLY env var - When set, skips payload extraction entirely - Default (unset): additive mode (local + payload binaries) New helper function: - decompressGzipToFile(): decompress without deleting source - Used for local binaries to preserve user files - ungzipFile() updated with warning about deletion Testing: - Local .gz binaries: decompress to /tmp/local-ext-*.bin - Original files preserved in container - Multiple binaries supported - Cleanup handled correctly Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

✅ Fixed in commit 6449fae
Added validation to track if any valid path was extracted:
hasValidPath := false
for _, path := range paths {
path = strings.TrimSpace(path)
if path == "" {
continue
}
hasValidPath = true
// ... process path
}
if !hasValidPath {
cleanupLocalFiles()
return nil, nil, nil, fmt.Errorf("--extension-binaries specified but no valid paths found (input was %q)", localBinaryPaths)
}Now correctly rejects inputs like ":" or whitespace with a clear error message.
Use named return error with deferred close handlers to ensure Close() errors are properly propagated instead of being silently discarded. This prevents ExtractAllTestBinaries from loading incomplete binaries if Close() fails during decompression. Addresses CodeRabbit review feedback.

Summary
Adds support for loading OTE extension binaries directly from the local filesystem via the
--extension-binariesCLI flag orEXTENSION_LOCAL_BINARIESenvironment variable. Supports multiple binaries using colon-separated paths.JIRA: INTEROP-9204 - OTE integration for OPP (Layered Products Interop)
Motivation
LP Interop Use Case
For Layered Products Interop (LP Interop) testing, the Step Container image is built as a composite container containing both:
openshift-tests(test orchestrator)/usr/bin/interop-tests-ext.gz)Since both binaries already exist in the same container filesystem, the current off-payload discovery mechanism introduces unnecessary complexity.
Current Off-Payload Discovery Overhead
The existing TestExtensionAdmission CRD-based discovery requires:
oc image extractto download and extract binaries from remote imagesThis overhead makes sense when:
This overhead is unnecessary when:
LP Interop Requirements
LP Interop needs to:

Background
This addresses LP Interop integration requirements for INTEROP-9204. The composite container pattern is the recommended approach for test scenarios where both the orchestrator and extension binaries are built and distributed together, as opposed to operator-based scenarios where binaries come from separate product images.
