name: microshift-release:validate-artifacts argument-hint: [--verbose] description: Validate MicroShift built artifacts (RPMs and bootc images) produced by ART for a release user-invocable: true allowed-tools: Bash

microshift-release:validate-artifacts

Synopsis

/microshift-release:validate-artifacts <version> [--verbose]

Description

Phase 1 of the MicroShift release process: verify that ART produced correct RPMs and bootc images for a given release. Checks Brew builds, NVR format, commit provenance, RHEL variants, mirror availability, shipment MR, stage catalog, and bootc image SHA consistency.

Supports all release types: X/Y (GA), Z (z-stream), RC, EC, and nightly.

Prerequisites

Requirement	Needed for	Mandatory?
VPN	Brew RPM checks, git commit verification	Yes — Brew checks WARN and degrade without it
GITLAB_API_TOKEN	Shipment MR checks (bootc_shipment_*)	No — bootc MR checks WARN and skip without it
Internet (mirrors)	rpm_mirror_*, bootc_mirror_*	Yes for RC/EC mirror checks

Arguments

• version (required): Full version string
  • Z-stream: 4.21.8
  • X/Y (GA): 4.22.0
  • RC: 4.22.0-rc.2
  • EC: 4.22.0-ec.5
  • nightly: 4.21.0-0.nightly-2026-03-23-021947
• --verbose (optional): Show detailed markdown report with evidence per check

Scripts Directory

SCRIPTS_DIR=plugins/microshift-release/scripts

Implementation

Step 1: Parse Arguments

1. Extract version from $ARGUMENTS — the first non-flag token
2. Pass through --verbose and --json flags if present

Step 2: Run the Script

bash $SCRIPTS_DIR/validate.sh <version> [--verbose]

Display stderr only if the script exits non-zero.

Step 3: Display Output

Display output verbatim — do not reformat, summarize, or add commentary. The script produces deterministic pre-formatted text.

Step 4: Handle Errors

If the script exits non-zero:

• VPN errors: Connect to VPN (Brew and git operations require it)
• Missing GITLAB_API_TOKEN: export GITLAB_API_TOKEN=<token> for shipment MR checks
• HTTP errors on mirrors: Mirrors may not be populated yet — check with ART

Checks Performed

RPM Checks (all release types)

Check	Description
rpm_packages_list	All expected RPM packages present in Brew build
rpm_filename_format	NVR matches expected pattern for this release type
rpm_commit_id	Commit hash from NVR is on the correct release-X.Y branch
rpm_rhel_version	Both el9 and el10 builds are present
rpm_mirror_ec	EC only: RPMs available at mirror.openshift.com/ocp-dev-preview/
rpm_mirror_rc	RC only: RPMs available at mirror.openshift.com/ocp/
rpm_xy0_commit_match	X.Y.0 only: commit matches the latest RC commit

Bootc Checks (4.18+, not nightly)

Check	Description
bootc_shipment_mr	Shipment MR exists in ocp-shipment-data GitLab repo
bootc_shipment_yaml_count	Exactly 1 YAML file in the MR
bootc_shipment_xy0_type	X/Y.0 only: spec.type == RHEA
bootc_shipment_xy0_release_notes	X/Y.0 only: releaseNotes.solution URL present
bootc_stage_advisory_url	environments.stage.advisory.internal_url present
bootc_catalog	Image published in catalog (stage or prod)
bootc_prod_xy0_type	X/Y.0 only: releaseNotes.type == RHEA
bootc_prod_advisory_url	X/Y.0 only: environments.prod.advisory.internal_url present
bootc_image_sha_match	RC/EC only: pullspec SHA matches advisory YAML SHA
bootc_mirror_ec	EC only: bootc-pullspec.txt at mirror/ocp-dev-preview/
bootc_mirror_rc	RC only: bootc-pullspec.txt at mirror/ocp/

Output Format

Short (default): Only actionable checks are shown. Skipped checks (not applicable for the release type) are hidden and summarized as a count. Details are shown only on failure.

(6 checks skipped — not applicable)

On failure, details appear below the failing check:

❌  rpm_packages_list       2 package(s) missing from Brew build
                            Missing: microshift-libs, microshift-selinux
                            Expected: microshift, microshift-libs, ...

Verbose (--verbose): Markdown table with full evidence per check (all checks shown including skips).

Examples

/microshift-release:validate-artifacts 4.21.8              # Z-stream
/microshift-release:validate-artifacts 4.22.0              # X/Y GA
/microshift-release:validate-artifacts 4.22.0-rc.2         # Release Candidate
/microshift-release:validate-artifacts 4.22.0-ec.5         # Engineering Candidate
/microshift-release:validate-artifacts 4.21.8 --verbose    # detailed report

Notes

• Read-only — does NOT create tickets, advisories, or modify external state. No confirmation required.
• VPN is required for Brew queries and git commit verification on internal repos
• GITLAB_API_TOKEN enables shipment MR checks; without it those checks show WARN
• Bootc checks are skipped for versions below 4.18 and for nightly builds
• Exit code is non-zero if any check returns FAIL
