# Global Hub New Release Workflow

Automates the complete end-to-end workflow for cutting a new Multicluster Global Hub release across all 6 repositories with full automation.

## Execution Instructions for Claude

**CRITICAL - Synchronous Execution Required**:

1. **Run Synchronously**: Execute the cut-release.sh script using the Bash tool WITHOUT the `run_in_background` parameter. The script must run synchronously to completion with a 600000ms (10 minute) timeout.

2. **No BashOutput Calls**: DO NOT use the BashOutput tool. The command runs synchronously and returns complete output when finished.

## When to Use This Skill

- Cutting a new Global Hub release (e.g., release-2.16, release-2.17)
- Updating an existing release branch with new configurations
- Setting up complete release infrastructure across all repositories
- Automating the entire release checklist workflow
- Creating coordinated PRs and branches for new releases

## Important Requirements

**RELEASE_BRANCH must be explicitly specified** - The skill does NOT auto-detect release versions. You must provide the exact release branch name.

**Two Operating Modes**:
- `CREATE_BRANCHES=true`: Create new release branches and push directly to upstream (for initial release creation)
- `CREATE_BRANCHES=false` (default): Update existing release branches via PR (for updating current releases)

## Version Mapping (ACM to Global Hub)

The skill uses ACM release branch names as the primary input and automatically calculates the corresponding Global Hub version.

### Version Mapping Table

| ACM Version | Release Branch | Global Hub Version | Bundle/Catalog Branch | OCP Versions |
|-------------|----------------|--------------------|----------------------|--------------|
| 2.14        | release-2.14   | v1.5.0             | release-1.5          | 4.15 - 4.19  |
| 2.15        | release-2.15   | v1.6.0             | release-1.6          | 4.16 - 4.20  |
| 2.16        | release-2.16   | v1.7.0             | release-1.7          | 4.17 - 4.21  |
| 2.17        | release-2.17   | v1.8.0             | release-1.8          | 4.18 - 4.22  |
| 2.18        | release-2.18   | v1.9.0             | release-1.9          | 4.19 - 4.23  |

**Formulas**:
- Global Hub version: v1.X.0 where X = ACM_MINOR - 9
- OCP versions: 4.(GH_MINOR + 10) to 4.(GH_MINOR + 14)

**Example**: ACM release-2.17 → Global Hub v1.8.0 → Bundle/Catalog release-1.8

## Repository Workflow

The skill manages releases across 6 repositories, each with its own dedicated script:

### Repository 1: multicluster-global-hub (Script 01)

**Repository**: [stolostron/multicluster-global-hub](https://github.com/stolostron/multicluster-global-hub)

**What it does** (4-part workflow):
1. **Update main branch**: Creates new `.tekton/` configuration files for new version (e.g., globalhub-1-8) with `target_branch="main"`, updates `Containerfile.*` version labels
2. **Create release branch**: Creates ACM release branch (e.g., release-2.17) from updated main
3. **Create PR to main**: Creates PR to upstream main with new release configurations
4. **Update previous release**: Updates previous release branch's `.tekton/` files to set `target_branch` to the previous release branch (e.g., globalhub-1-7 files updated to `target_branch="release-2.16"`)

**Key behavior**:
- New `.tekton/` files (e.g., globalhub-1-8) created by **copying** old files (globalhub-1-7), not renaming
- Old `.tekton/` files (globalhub-1-7) remain on main with `target_branch="main"`
- Previous release branch gets updated so its files point to itself (not main)
- Ensures continuous file naming progression: globalhub-1-6 → globalhub-1-7 → globalhub-1-8

**Outputs**: 1 PR (new release configurations to main), direct pushes to release branches

### Repository 2: openshift/release (Script 02)

**Repository**: [openshift/release](https://github.com/openshift/release)

**What it does**:
- Updates main branch CI configuration (promotion, fast-forward)
- Creates new release pipeline configuration
- Auto-generates presubmit/postsubmit jobs using `make update`
- Validates container engine availability (Docker or Podman)
- Creates PR with all CI changes

**Outputs**: 1 PR (CI configuration)

### Repository 3: operator-bundle (Script 03)

**Repository**: [stolostron/multicluster-global-hub-operator-bundle](https://github.com/stolostron/multicluster-global-hub-operator-bundle)

**What it does**:
- Creates bundle branch using Global Hub version (e.g., release-1.8 from v1.8.0)
- Updates `images_digest_mirror_set.yaml` with new image tags
- Renames and updates tekton pipelines (pull-request and push)
- Updates bundle image labels to new version
- Updates `konflux-patch.sh` image references
- Creates PR with all bundle changes

**Outputs**: 1 PR (bundle updates to main)

### Repository 4: operator-catalog (Script 04)

**Repository**: [stolostron/multicluster-global-hub-operator-catalog](https://github.com/stolostron/multicluster-global-hub-operator-catalog)

**What it does**:
- Creates catalog branch using Global Hub version (e.g., release-1.8)
- Updates `images-mirror-set.yaml` with new image tags
- **Adds** new OCP version pipelines (e.g., OCP 4.21 for release-1.8)
- **Removes** old OCP version pipelines (e.g., OCP 4.16)
- Updates existing OCP version pipelines (4.17-4.20)
- Updates `README.md` with new version information
- Updates GitHub Actions workflow for new release branch
- Creates **2 PRs**:
  - Main PR: New release configuration to main branch
  - Cleanup PR: Remove GitHub Actions from old release branch

**OCP Version Formula**: OCP_MIN = 4.(10 + GH_MINOR), OCP_MAX = OCP_MIN + 4

**Outputs**: 2 PRs (main release + cleanup)

### Repository 5: glo-grafana (Script 05)

**Repository**: [stolostron/glo-grafana](https://github.com/stolostron/glo-grafana)

**What it does**:
- Creates grafana branch using Global Hub version (e.g., release-1.8)
- Renames and updates tekton pipelines (pull-request and push)
- Updates branch references in pipeline files

**Outputs**: Branch creation only (no PR)

### Repository 6: postgres_exporter (Script 06)

**Repository**: [stolostron/postgres_exporter](https://github.com/stolostron/postgres_exporter)

**What it does**:
- Creates postgres_exporter branch using ACM version (e.g., release-2.17)
- Renames and updates tekton pipelines (pull-request and push)
- Updates branch references in pipeline files

**Outputs**: Branch creation only (no PR)

```

## Execution Modes

**IMPORTANT**: RELEASE_BRANCH environment variable is REQUIRED for all execution modes.

The main orchestration script supports three modes:

### 1. Interactive Mode (Default)
```bash
RELEASE_BRANCH=release-2.17 ./scripts/cut-release.sh
```
Prompts user to select which repositories to update (1-6, comma-separated, or all).

### 2. All Repositories Mode
```bash
RELEASE_BRANCH=release-2.17 ./scripts/cut-release.sh all
```
Updates all 6 repositories in sequence.

### 3. Selective Mode
```bash
RELEASE_BRANCH=release-2.17 ./scripts/cut-release.sh 1,2,3    # Update specific repos
RELEASE_BRANCH=release-2.17 ./scripts/cut-release.sh 3,4      # Update only bundle and catalog
```

### 4. CREATE_BRANCHES Mode (Create New Branches)
```bash
CREATE_BRANCHES=true RELEASE_BRANCH=release-2.17 ./scripts/cut-release.sh all
```
Creates new release branches and pushes directly to upstream (requires write access).

### 5. UPDATE Mode (Default - Create PRs)
```bash
CREATE_BRANCHES=false RELEASE_BRANCH=release-2.17 ./scripts/cut-release.sh all
# or simply:
RELEASE_BRANCH=release-2.17 ./scripts/cut-release.sh all
```
Updates existing release branches by creating pull requests.

### 6. Standalone Script Execution
Each script can be run independently:
```bash
RELEASE_BRANCH="release-2.17" GH_VERSION="v1.8.0" CREATE_BRANCHES=false ./scripts/03-bundle.sh
```

## Environment Variables

The main orchestration script calculates and exports these variables for child scripts:

| Variable | Description | Example | Required |
|----------|-------------|---------|----------|
| `RELEASE_BRANCH` | ACM release branch | `release-2.17` | **YES** - Must be explicitly set |
| `CREATE_BRANCHES` | Operating mode (true/false) | `false` | Optional (default: false) |
| `GITHUB_USER` | GitHub username for PRs | `yanmxa` | Optional (auto-detected from git) |
| `ACM_VERSION` | ACM version number | `2.17` | Auto-calculated |
| `GH_VERSION` | Global Hub version | `v1.8.0` | Auto-calculated |
| `GH_VERSION_SHORT` | Short Global Hub version | `1.8` | Auto-calculated |
| `BUNDLE_BRANCH` | Bundle release branch | `release-1.8` | Auto-calculated |
| `BUNDLE_TAG` | Bundle image tag | `globalhub-1-8` | Auto-calculated |
| `CATALOG_BRANCH` | Catalog release branch | `release-1.8` | Auto-calculated |
| `CATALOG_TAG` | Catalog image tag | `globalhub-1-8` | Auto-calculated |
| `GRAFANA_BRANCH` | Grafana release branch | `release-1.8` | Auto-calculated |
| `GRAFANA_TAG` | Grafana tag | `globalhub-1-8` | Auto-calculated |
| `POSTGRES_TAG` | Postgres image tag | `globalhub-1-8` | Auto-calculated |
| `OCP_MIN` | Minimum OCP version number | `417` | Auto-calculated |
| `OCP_MAX` | Maximum OCP version number | `421` | Auto-calculated |
| `OPENSHIFT_RELEASE_PATH` | Path to openshift/release clone | `/tmp/openshift-release` | Optional |
| `WORK_DIR` | Working directory for repos | `/tmp/globalhub-release-repos` | Optional |

Individual scripts can be run standalone by providing the required variables.

## Platform Compatibility

All scripts are compatible with:
- **macOS** (ARM/Apple Silicon and Intel) - Uses `sed -i ""` syntax
- **Linux** (x86_64) - Uses `sed -i` syntax

Scripts automatically detect the OS and use the appropriate `sed` syntax.

## Prerequisites

1. **Git configured** with your GitHub credentials
2. **GitHub CLI (`gh`)** authenticated with your account
3. **Fork** of https://github.com/openshift/release (for script 02)
4. **Container engine** (Docker or Podman) running (for script 02's `make update`)
5. **Write access** to all stolostron repositories

## Workflow Summary

When running the complete workflow (`cut-release.sh all`):

### Phase 1: Main Repository (Script 01)
- Detects latest release and calculates next version
- Creates release branch from main
- Updates .tekton/ and Containerfile.*
- Creates version bump PR to main branch

### Phase 2: OpenShift CI (Script 02)
- Validates container engine availability
- Updates CI configurations for new release
- Auto-generates job configurations
- Creates PR to openshift/release

### Phase 3: Bundle (Script 03)
- Creates bundle release branch
- Updates all bundle configurations and tekton pipelines
- Creates PR to main branch

### Phase 4: Catalog (Script 04)
- Creates catalog release branch
- Manages OCP version lifecycle (add newest, remove oldest)
- Updates all catalog configurations
- Creates 2 PRs (main release + old branch cleanup)

### Phase 5: Grafana (Script 05)
- Creates grafana release branch
- Updates tekton pipelines

### Phase 6: Postgres Exporter (Script 06)
- Creates postgres_exporter release branch
- Updates tekton pipelines

## Total Output

After running all 6 scripts:

**Pull Requests Created**: 5 PRs
1. Main repo: Version bump PR
2. OpenShift CI: CI configuration PR
3. Bundle: Bundle update PR
4. Catalog: New release configuration PR
5. Catalog: Cleanup PR for old branch

**Branches Created**: 5 branches
1. `multicluster-global-hub`: `release-2.17`
2. `operator-bundle`: `release-1.8`
3. `operator-catalog`: `release-1.8`
4. `glo-grafana`: `release-1.8`
5. `postgres_exporter`: `release-2.17`

## Error Handling

The orchestration script includes error handling:
- Each script can fail independently
- User is prompted to continue or abort after failures
- Final summary shows completed vs failed repositories
- Exit code indicates overall success/failure

## Example Usage

### Update all repositories (UPDATE mode - creates PRs):
```bash
RELEASE_BRANCH=release-2.17 ./.claude/skills/cut-release/scripts/cut-release.sh all
```

### Create new release branches (CREATE_BRANCHES mode - pushes directly):
```bash
CREATE_BRANCHES=true RELEASE_BRANCH=release-2.18 ./.claude/skills/cut-release/scripts/cut-release.sh all
```

### Interactive selection:
```bash
RELEASE_BRANCH=release-2.17 ./.claude/skills/cut-release/scripts/cut-release.sh
# Then select: 3,4 (to update only bundle and catalog)
```

### Update specific repositories:
```bash
RELEASE_BRANCH=release-2.17 ./.claude/skills/cut-release/scripts/cut-release.sh 1,2,3
```

### Standalone script execution:
```bash
RELEASE_BRANCH="release-2.17" GH_VERSION="v1.8.0" CREATE_BRANCHES=false ./scripts/04-catalog.sh
```
