Summary

Automate Global Hub release configuration updates across 6 repositories using Claude Code, reducing manual effort by >90%.

Problem

Current release process requires manual updates across 6 repositories:

• multicluster-global-hub, openshift/release, operator-bundle, operator-catalog, glo-grafana, postgres_exporter
• Updates include: prow configs, Konflux pipelines, Tekton configurations, image versions, OCP lifecycle management
• Process is time-consuming, error-prone, and requires deep domain knowledge

Solution

Create Claude Code automation skill that handles:

Repository Updates:
1. multicluster-global-hub - .tekton/ configs, Containerfile versions, release branches
2. openshift/release - CI configs, presubmit/postsubmit jobs
3. operator-bundle - Image mirror sets, Tekton pipelines, bundle labels
4. operator-catalog - OCP version lifecycle (add new, remove old)
5. glo-grafana - Release branches, Tekton pipelines
6. postgres_exporter - Release branches, Tekton pipelines

Features:

• Two modes: CUT (direct push) / UPDATE (PRs)
• Automatic version calculation (ACM → Global Hub → OCP)
• Cross-platform support (macOS, Linux)
• Interactive & batch execution
• Progress tracking & error handling

Output per Release:

• All configurations updated automatically
