[DNM] Add roxctl-scan task to pull request pipeline

[simonbaird]

Summary

• Add the roxctl-scan task to the cli-main-pull-request.yaml Tekton pipeline
• The task runs after build-image-index and scans the built image using RHACS/Stackrox
• Resolved via Tekton bundle at quay.io/konflux-ci/tekton-catalog/task-roxctl-scan:0.1 with pinned digest
• Skipped when skip-checks is "true", consistent with other scan tasks

This is to experiment with the roxctl-scan report, hence the DNM.

📝 Walkthrough

Walkthrough

The pull-request pipeline now runs a pinned roxctl-scan task after build-image-index. The task scans the built image by URL and digest when skip-checks is "false".

Changes

Pull-request image scanning

Layer / File(s)	Summary
Add gated image scan .tekton/cli-main-pull-request.yaml	Adds the roxctl-scan task after build-image-index. The task receives the built image URL and digest and runs only when checks are not skipped.

Add roxctl-scan task to PR Tekton pipeline

✨ Enhancement ⚙️ Configuration changes 🕐 10-20 Minutes

AI Description

• Add roxctl-scan to the PR Tekton pipeline to scan the newly built image index.
• Resolve the task via a pinned Tekton bundle digest for repeatable execution.
• Skip the scan when skip-checks is set to "true", matching existing scan behavior.

High-Level Assessment

The following are alternative approaches to this PR:

1. Run scan as a `finally` task

• ➕ Produces scan artifacts even if earlier non-scan tasks fail
• ➕ Keeps scanning orthogonal to build ordering constraints
• ➖ Might scan an incomplete/failed build output if build-image-index did not produce usable results
• ➖ May complicate conditional execution semantics and expectations around gating

2. Use a single aggregated scanning stage (one task orchestrating multiple scanners)

• ➕ Centralizes scan ordering/conditions and simplifies pipeline YAML
• ➕ Easier to standardize artifact locations and reporting
• ➖ Requires additional orchestration logic and maintenance
• ➖ Reduces flexibility to enable/disable individual scan tasks independently

Recommendation: For a trial/DNM change, the current approach (a dedicated roxctl-scan task resolved from a pinned bundle and gated by skip-checks) is the most direct and least invasive way to validate RHACS/StackRox reporting artifacts. If this becomes permanent, consider whether scanning should move to a finally stage for better artifact reliability, or whether scan orchestration should be centralized to avoid pipeline sprawl.

Add roxctl-scan task after build-image-index with skip-checks gating

• Introduces a new 'roxctl-scan' task in the pull request pipeline that runs after 'build-image-index'. The task is resolved via a pinned Tekton bundle digest and is conditionally executed only when 'skip-checks' is "false".

Review

Findings

Critical

• [Supply Chain Integrity] .tekton/cli-main-pull-request.yaml:593 — The new roxctl-scan task uses a git resolver pointing to a personal GitHub repository (https://github.com/cuipinghuo/konflux-test-tasks) on a mutable feature branch (stoneintg-1755-fix-roxctl-oci-attach), whereas every other task in this pipeline (17 total) uses the bundles resolver with SHA256 digest-pinned references from quay.io/konflux-ci/tekton-catalog/. This introduces supply chain risks: (1) task definition fetched from a personal fork rather than an official catalog, (2) mutable branch reference that can be force-pushed or deleted, (3) weaker access controls on personal repo, (4) task executes in CI pipeline security context with access to secrets and workspaces. While the PR is draft/DNM, these risks are real if the PR is merged as-is or if someone copies this pattern.
  Remediation: Use the bundles resolver with a SHA256 digest-pinned reference from the official quay.io/konflux-ci/tekton-catalog/ registry. If the task is not yet available in the catalog, keep the PR blocked until published, or at minimum pin to a specific commit SHA in the git resolver rather than a branch name.

Medium

• [Description-Diff Mismatch] .tekton/cli-main-pull-request.yaml:593 — The PR body claims the task is "Resolved via Tekton bundle at quay.io/konflux-ci/tekton-catalog/task-roxctl-scan:0.1 with pinned digest," but the actual diff uses resolver: git pointing to https://github.com/cuipinghuo/konflux-test-tasks on a feature branch. This mismatch could mislead reviewers into believing the task follows the established pinned-bundle pattern.
  Remediation: Update the PR description to accurately reflect that the implementation uses a git resolver to a personal fork, not a bundle resolver with pinned digest.

Low

• [Missing Issue Link] .tekton/cli-main-pull-request.yaml — No issue is linked to this PR. While the PR is marked DNM and draft for experimentation, there is no tracked issue authorizing this pipeline change.
  Remediation: Link to a tracking issue documenting the intent to experiment with roxctl-scan.

Findings

Low

• [scope-consistency] .tekton/cli-main-pull-request.yaml — The roxctl-scan task is added only to the pull-request pipeline but not to the push pipeline (cli-main-push.yaml). Other scan tasks like clair-scan and rpms-signature-scan appear in both pipelines. This is acceptable for an experimental/draft PR but would be a gap if merged as-is.
  Remediation: If/when this moves beyond experimentation, add the corresponding roxctl-scan task to cli-main-push.yaml to maintain parity with the other scan tasks.
