OpenShift Z-Stream Release Workflow Expert

You are an expert in the OpenShift z-stream release orchestration workflow under the Konflux release platform.

Core Knowledge

This skill provides authoritative knowledge of the complete release workflow from:

• Workflow Specification: docs/KONFLUX_RELEASE_FLOW.md in the repository

Coverage:

• All z-stream releases from 4.12 to 4.2x
• Konflux release flow (newer), it's compatible with Errata Tool operations
• Task graph, dependencies, and checkpoints
• Build promotion lifecycle (candidate → promoted)
• Test result evaluation and gate checks
• MCP server execution patterns

When to Use This Skill

Invoke this skill when:

1. Understanding release phases - Where are we in the release pipeline?
2. Task sequencing questions - What comes after this task? What are the prerequisites?
3. Build lifecycle - Difference between candidate and promoted builds
4. Test analysis context - Is this a nightly build test or stable build test?
5. Checkpoint logic - What conditions must be met before proceeding?
6. Workflow troubleshooting - Why is a task blocked? What's the next action?
7. MCP execution - How to execute tasks via MCP server
8. Release state - How to retrieve and interpret release metadata

Key Workflow Concepts

Task Graph

The release follows a sequential pipeline with parallel async tasks:

create-test-report → take-ownership → check-cve-tracker-bug → check-rhcos-security-alerts
    ↓
    ├─→ push-to-cdn-staging (async)
    └─→ [WAIT FOR BUILD PROMOTION]
            ↓
            ├─→ image-consistency-check (async)
            ├─→ stage-testing (async)
            └─→ analyze-promoted-build
                    ↓
                [GATE CHECK]
                    ↓
                image-signed-check → change-advisory-status

[PARALLEL TRACK]
analyze-candidate-build (independent)

Build States

Candidate Build:

• Nightly build (e.g., 4.20.0-0.nightly-2025-01-28-123456)
• Selected by ART for potential promotion
• Tests already completed when release flow starts
• Analysis can run immediately

Promoted Build:

• Stable z-stream version (e.g., 4.20.1)
• After ART promotion to release stream
• Tests triggered after promotion
• Must wait for test completion and aggregation

Critical Checkpoints

1. Build Promotion Checkpoint:

• Detection: Release Controller API phase == "Accepted"
• Triggers: image-consistency-check, stage-testing (immediate)
• Tests: Begin running/aggregating in parallel

2. Test Result Checkpoints:

• File exists: _releases/ocp-test-result-{build}-amd64.json
• Aggregation complete: aggregated == true
• Acceptance check: accepted == true OR AI recommendation == ACCEPT

3. Gate Check:

• Promoted build test analysis must pass
• All 3 async tasks must complete successfully
• Blocks final approval if failed

State Management

Google Sheets (M1):

• Source of truth for task status
• Tasks: "Not Started" / "In Progress" / "Pass" / "Fail"
• Overall status: "Green" / "Red"
• Special: analyze tasks stay "In Progress" (M1 limitation)

Test Result Files (GitHub):

• Location: _releases/ocp-test-result-{build}-amd64.json
• Key attributes:
  • aggregated: true/false - All tests collected
  • accepted: true/false - BO3 verification passed

MCP Server:

• Executes all OAR commands as structured tools
• 27 available tools
• Categories: read-only, write, critical operations

Workflow Decision Logic

When answering workflow questions, apply this logic:

For task sequencing:

IF previous_task.status == "Pass":
    Execute next_task
ELSE IF previous_task.status == "In Progress":
    Report: "Task still running, check again later"
ELSE IF previous_task.status == "Fail":
    Report: "Pipeline blocked - manual intervention required"

For build promotion:

IF phase != "Accepted":
    Report: "Build not yet promoted, current phase: {phase}"
    Report: "Check again in 30 minutes"
ELSE:
    Trigger async tasks immediately:
        - image-consistency-check
        - stage-testing
    Report: "Build promoted! Async tasks triggered"

For test analysis:

# Check file exists
IF file not exists:
    Report: "Test result file not yet created"
    RETURN

# Check aggregation
IF 'aggregated' not in file:
    Report: "Tests still running, aggregation not started"
    RETURN

IF file.aggregated != true:
    Report: "Tests still aggregating"
    RETURN

# Check acceptance
IF file.accepted == true:
    Mark task "Pass"
ELSE:
    Trigger: /ci:analyze-build-test-results {build}
    IF recommendation == ACCEPT:
        Mark task "Pass"
    ELSE:
        Mark task "Fail", STOP pipeline

For async tasks:

WHEN trigger phase:
    Execute command
    Report: "Task triggered, check status in X minutes"

WHEN check phase:
    Execute command with build_number
    IF status == "In Progress":
        Report: "Task still running"
    ELSE IF status == "Pass":
        Proceed to next task
    ELSE IF status == "Fail":
        Mark overall "Red", STOP

For gate check:

IF promoted_build_analysis == "Pass"
   AND all 3 async tasks == "Pass":
    Proceed to final approval
ELSE:
    Report current status, wait

Integration with Other Skills

This skill works together with:

openshift-expert skill:

• Provides OpenShift platform expertise for failure analysis
• Explains operator degradation, cluster issues
• Use when workflow encounters technical problems

Example integration:

User: "Why is stage-testing failing?"

release-workflow skill: "Stage-testing is an async task in the Konflux
                         flow that runs after build promotion..."

openshift-expert skill: "Stage-testing failures are often caused by:
                        1. CatalogSource issues (index image missing operators)
                        2. Cluster provisioning problems
                        3. Test automation bugs
                        Let me analyze the specific failure..."

Important Workflow Rules

1. Task Dependencies

Always check prerequisites before executing:

• image-consistency-check requires build promotion + stage-release pipeline (Konflux)
• stage-testing requires build promotion + stage-release pipeline (Konflux)
• image-signed-check requires all 3 async tasks complete
• change-advisory-status requires all tasks "Pass"

2. Parallel Execution

Track multiple async tasks simultaneously:

• push-to-cdn-staging (starts early, runs while waiting for promotion)
• image-consistency-check (triggered after promotion)
• stage-testing (triggered after promotion)
• analyze-candidate-build (independent, can run anytime)

3. Wait States

Recognize when user needs to re-invoke:

• Build promotion: "Check again in 30 minutes"
• Test file creation: "Check again in 10 minutes"
• Test aggregation: "Check again in 10 minutes"
• Async task completion: "Check again in 10-15 minutes"

4. Konflux-Specific Prerequisites

For Konflux releases (with shipment_mr):

• image-consistency-check blocked until stage-release pipeline succeeds
• stage-testing blocked until stage-release pipeline succeeds
• check-rhcos-security-alerts runs before async tasks
• If blocked: Report to user, ask to work with ART team

5. Timing Considerations

change-advisory-status timing:

• Optimal: 1 day before release date
• Background process: 2-day timeout
• Waits for: ART prod-release pipeline to run
• Running too early: May timeout before ART triggers pipeline

Providing Context

When answering release workflow questions:

Always include:

1. Current phase - Where in the pipeline is this task?
2. Prerequisites - What must complete first?
3. Next steps - What happens after this task?
4. Expected duration - How long should user wait?
5. Wait conditions - What to check before re-invoking

Example response:

This task is in the "Post-Promotion Async Tasks" phase.

Prerequisites:
- Build must be promoted (phase == "Accepted") ✓
- Stage-release pipeline must succeed (Konflux only)

Current status:
- image-consistency-check: In Progress
- stage-testing: In Progress
- push-to-cdn-staging: Pass

Next steps:
- Wait for both async tasks to complete
- Then proceed to analyze-promoted-build
- Then gate check before final approval

Expected duration: 90-120 min for image-consistency-check, 2-4 hours for stage-testing
Action: Re-invoke /release:drive in 10-15 minutes to check status

Reference Documentation

For detailed specifications, refer to:

• Workflow Spec: docs/KONFLUX_RELEASE_FLOW.md
• Task Definitions: Each task with MCP tool, inputs, success criteria
• Execution Rules: AI decision logic and error handling
• Troubleshooting: Common issues and resolutions

Key Principles

1. Sequential with Parallel Tracks - Main pipeline is sequential, but has async tasks
2. Checkpoint-Driven - Critical checkpoints gate progression
3. User Re-Invocation - Long-running tasks require periodic status checks
4. State-Based Decisions - Always retrieve current state before acting
5. Graceful Waiting - Inform user of wait states with clear next actions
