OCPBUGS-114718: Only set insecure flag when accessing mirror for oc adm

[bfournie]

Gate the oc adm --insecure flag behind mirror configuration so its only added to the command when a mirror is configured.

Summary by CodeRabbit

• Bug Fixes
  • Improved security for release information and image extraction commands by preserving TLS verification when no mirror configuration is present.
  • Mirror-specific insecure mode is now enabled only when required by configured mirrors.

📝 Walkthrough

Walkthrough

The change removes unconditional --insecure=true flags from RHCOS release-info and image-extract commands. The flag and ICSP arguments are now added only when mirror configuration exists. Tests cover both execution modes.

Changes

RHCOS mirror argument handling

Layer / File(s)	Summary
Mirror argument construction and command wiring pkg/asset/rhcos/releaseextract.go	appendMirrorArgs adds mirror-specific arguments for mirrored installations and leaves non-mirrored commands unchanged. Release-info and image-extract commands use this helper.
Mirror argument and command validation pkg/asset/rhcos/releaseextract_test.go	Tests verify conditional --insecure=true and ICSP arguments for mirror argument construction, release-info, and image-extract commands.

Estimated code review effort: 2 (Simple) | ~15 minutes

Merge Risk: ⚪ Minimal · up to 56c10

The change limits the oc adm insecure flag to mirror-based access, avoiding unnecessary insecure behavior when no mirror is configured; no actionable merge-blocking risk remains beyond normal checks and review.

Full details: Stable And Deterministic Test Names

Explanation

PASS. The pull request adds standard Go testing subtests, not Ginkgo tests. All t.Run names come from static literals: no mirror omits --insecure, mirror includes --insecure and icsp file, connected install, and mirrored install. No dynamic pod, node, namespace, timestamp, IP, UUID, or generated identifier appears in a test title.

Full details: Test Structure And Quality

Explanation

PASS: The PR adds standard Go tests using testing.T subtests and testify/assert; it does not add Ginkgo test code. The target package has no Ginkgo lifecycle blocks, It blocks, Eventually, or Consistently calls. Therefore, the Ginkgo-specific requirements are not applicable. The new tests also defer temporary-file cleanup and perform no cluster operations or indefinite waits.

Full details: Microshift Test Compatibility

Explanation

PASS: The pull request adds standard Go unit tests in pkg/asset/rhcos/releaseextract_test.go using testing.T, t.Run, and testify/assert. It adds no Ginkgo e2e tests such as It, Describe, Context, or When. Therefore, the MicroShift test compatibility check does not apply.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

PASS: The pull request adds only Go unit tests in pkg/asset/rhcos/releaseextract_test.go. They use testing.T and t.Run, not Ginkgo It, Describe, Context, or When. The tests contain no multi-node or HA assumptions, so the SNO compatibility check is not applicable.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS: The pull request changes only pkg/asset/rhcos/releaseextract.go and its test file. The diff updates oc adm release info and oc image extract argument construction and adds unit tests. It does not add or modify deployment manifests, operators, controllers, replicas, affinity, topology spread, node selectors, tolerations, or PDBs. The topology-aware scheduling check is therefore not applicable.

Full details: Ote Binary Stdout Contract

Explanation

No OTE stdout contract violation was introduced. The pull request changes only pkg/asset/rhcos/releaseextract.go and adds tests; no process-level main, init, or suite setup changed, and no added fmt.Print*, os.Stdout, or logging-to-stdout call exists. The new logrus.Debugf call is covered by openshift-install logging configuration, which discards the logger output and sends the hook to os.Stderr. agent.ExecuteOC captures oc stdout in a buffer. The temporary-file Write targets an explicitly opened file.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

PASS. The pull request adds standard Go unit tests using testing.T and testify/assert, not Ginkgo e2e tests. The tests only construct command arguments and do not connect to public hosts, pull images, resolve DNS, or use IPv4 addresses. The registry.example.com and mirror.example.com values are inert test strings.

Full details: No-Weak-Crypto

Explanation

PASS. The pull request changes oc argument construction, mirror handling, and cleanup logic. The diff adds no MD5, SHA-1, DES, RC4, 3DES, Blowfish, ECB, custom crypto, or secret/token comparison. The existing SHA-256 cache verification and bytes.Equal comparison are unchanged from origin/main and do not match the stated failure conditions.

Full details: Container-Privileges

Explanation

PASS. The pull request changes only pkg/asset/rhcos/releaseextract.go and its Go tests. The committed diff contains no privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, or allowPrivilegeEscalation settings. No container or Kubernetes manifest changed.

Full details: No-Sensitive-Data-In-Logs

Explanation

No sensitive-data logging was introduced. The only new log statement is Using mirror configuration, which contains no secret or customer value. The existing command debug logs still include command arguments, image names, and paths, but the pull request does not add secret values to them; pullSecret remains passed to agent.ExecuteOC and is written to a temporary file, not logged. Mirror entries are serialized to the temporary ICSP file, while logs contain only its generated path.

Add focused unit tests for both mirror states.

pkg/asset/rhcos/iso_test.go does not exercise getImageFromRelease or extractFileFromImage. Assert that non-mirrored commands omit --insecure=true, while mirrored commands include it with the generated mirror argument.

If the user is not using a mirror but has a proxy between them and the Internet (with the proxy's CA passed in the additional trust bundle, presumably), will oc know to trust the proxy's CA?
