Android Production Workflow

Generates GitHub Actions workflows for production deployment with staged rollouts and rollout management.

Prerequisites

• Service account setup complete
• Package name known
• GitHub environment "production" created

Inputs

Process

Step 1: Verify Fastlane Setup

Ensure Fastlane is configured:

bundle exec fastlane lanes

Expected output should show deploy_production, increase_rollout, and halt_rollout lanes.

Step 2: Create Production Deployment Workflow

Create .github/workflows/deploy-production.yml:

name: Deploy to Production

on:
  workflow_dispatch:
    inputs:
      rollout_type:
        description: 'Rollout type'
        required: true
        type: choice
        options:
          - staged
          - full
        default: 'staged'
      rollout_percentage:
        description: 'Rollout percentage (only for staged: 0.05-1.0, e.g., 0.1 for 10%)'
        required: false
        default: '0.05'

Key features:

• ✅ Uses Fastlane for deployment
• ✅ Supports full and staged rollouts
• ✅ Creates GitHub releases automatically
• ✅ Pinned all actions to commit SHAs
• ✅ Test job runs before deployment
• ✅ Manual trigger only (no automatic tag deployment)

Step 3: Create Rollout Management Workflow

Note: Fastlane provides full support for rollout management through dedicated lanes.

Create .github/workflows/manage-rollout.yml:

name: Manage Production Rollout

on:
  workflow_dispatch:
    inputs:
      action:
        description: 'Rollout action'
        required: true
        type: choice
        options:
          - promote
          - halt
          - complete
      from_track:
        description: 'Source track (for promote action)'
        required: false
        type: choice
        options:
          - internal
          - alpha
          - beta
        default: 'beta'
      percentage:
        description: 'Rollout percentage (for promote: 0.05-1.0, e.g., 0.2 for 20%)'
        required: false
        default: '0.05'

jobs:
  manage-rollout:
    runs-on: ubuntu-latest
    environment: production

    steps:
      - name: Checkout code
        uses: actions/checkout@11bd71901bbe5b1630ceea73d27597364c9af683  # v4.2.2

        with:

          distribution: 'temurin'

      - name: Set up Ruby
        uses: ruby/setup-ruby@v1
        with:
          ruby-version: '3.2'
          bundler-cache: true

      - name: Create Service Account File
        run: echo "${{ secrets.SERVICE_ACCOUNT_JSON_PLAINTEXT }}" > service-account.json

      - name: Increase Rollout
        if: github.event.inputs.action == 'promote'
        env:
          PLAY_STORE_SERVICE_ACCOUNT: service-account.json
        run: bundle exec fastlane increase_rollout rollout:${{ github.event.inputs.percentage }}

      - name: Complete Rollout (100%)
        if: github.event.inputs.action == 'complete'
        env:
          PLAY_STORE_SERVICE_ACCOUNT: service-account.json
        run: bundle exec fastlane increase_rollout rollout:1.0

      - name: Halt Rollout
        if: github.event.inputs.action == 'halt'
        env:
          PLAY_STORE_SERVICE_ACCOUNT: service-account.json
        run: bundle exec fastlane halt_rollout

      - name: Cleanup Service Account
        if: always()
        run: rm -f service-account.json

      - name: Notify result
        if: success()
        run: |
          echo "✅ Rollout action completed: ${{ github.event.inputs.action }}"
          if [ "${{ github.event.inputs.action }}" == "promote" ]; then
            echo "📊 Promoted from ${{ github.event.inputs.from_track }} to production"
            echo "📊 Rollout percentage: ${{ github.event.inputs.percentage }}"
          fi

Key features:

• ✅ Uses Fastlane for rollout management
• ✅ Supports increase, complete, and halt actions
• ✅ Pinned all actions to commit SHAs

Step 3: Create Environment Setup Guide

Add to .github/workflows/README.md:

# GitHub Actions Workflows

## Production Environment Setup

**REQUIRED:** Create production environment for manual approval:

1. Go to: Repository → Settings → Environments
2. Click "New environment"
3. Name: `production`
4. Check "Required reviewers"
5. Add yourself and/or team members
6. Click "Save protection rules"

This ensures production deployments require manual approval.

## Workflows

### deploy-internal.yml
- **Trigger:** Push to main/develop
- **Track:** Internal testing
- **Approval:** None (automatic)

### deploy-production.yml
- **Trigger:** Tag push (v*) or manual
- **Track:** Production
- **Approval:** Required (via environment)
- **Rollout:** Staged (default 5%)

### manage-rollout.yml
- **Trigger:** Manual only
- **Actions:** increase, halt, resume, complete
- **Use:** Control production rollout percentage

## Usage

**Deploy to internal:**
```bash
git push origin main

Deploy to production:

git tag v1.0.0
git push origin v1.0.0
# Then approve in GitHub Actions tab

Increase rollout to 20%:

1. Go to: Actions → Manage Production Rollout
2. Click "Run workflow"
3. Select action: "increase"
4. Enter percentage: "20"
5. Click "Run workflow"

Emergency halt:

1. Go to: Actions → Manage Production Rollout
2. Select action: "halt"
3. Click "Run workflow"

## Verification

**MANDATORY:** Validate workflows:

```bash
# Validate YAML syntax
yamllint .github/workflows/deploy-production.yml
yamllint .github/workflows/manage-rollout.yml

# Verify package name
grep "packageName:" .github/workflows/*.yml

Outputs

Completion Criteria

• deploy-production.yml exists and is valid
• manage-rollout.yml exists and is valid
• Package names are correct in both files
• GitHub "production" environment created
• Required reviewers configured
