Deployment Automation Skill

Complete deployment system for Holochain hApps with proven patterns from successful production releases (v0.1.9, 100% cross-platform success).

Capabilities

• Multi-Repository Coordination: Main repo (WebHapp), Kangaroo submodule (desktop apps), Homebrew (macOS distribution), git submodule sync
• Cross-Platform Deployment: macOS ARM64 + x64, Windows x64, Linux DEB + AppImage, WebApp packaging, Holostrap production network
• CI/CD Pipeline: GitHub Actions workflows, manual GitHub CLI asset uploads (100% reliable), cross-platform build verification
• Release Automation: 7-step manual process (proven 100% success), version sync across repos, changelog and release notes

Quick Start

New Release

"Deploy version 0.2.0 with all platforms"

Deployment Troubleshooting

"The macOS build failed to upload assets"

Environment Setup

"Set up deployment environment for a new team member"

Proven Patterns

CI/CD Asset Upload Fix

This pattern eliminated asset upload failures in v0.1.9:

# Instead of unreliable electron-builder auto-publishing
- name: build and upload the app (macOS)
  run: |
    yarn build:mac-arm64
    ls dist
    # Use wildcard to handle filename variations
    find dist -name "*.dmg" -exec gh release upload "v${{ env.APP_VERSION }}" {} \;

7-Step Release Process

1. Main Repository Updates - Version bump + changelog
2. WebHapp Build - bun package in Nix environment
3. GitHub Release Creation - Manual release with webhapp upload
4. Kangaroo Repository Update - Copy webhapp + version sync
5. CI/CD Trigger - Push to release branch
6. Build Monitoring - Cross-platform build verification
7. Release Notes Finalization - Cross-link desktop app links

Cross-Platform Build Benchmarks (v0.1.9)

• macOS ARM64: 1m46s (fastest)
• macOS x64: 3m2s
• Windows x64: 2m54s
• Linux x64: ~4m (includes post-install scripts)

Architecture Integration

Repository Structure

Main Repository (requests-and-offers)
├── WebHapp build and packaging
├── Release coordination and version management
└── Cross-repository linking

Kangaroo Submodule (deployment/kangaroo-electron)
├── Desktop app builds (Windows/macOS/Linux)
├── GitHub Actions CI/CD + code signing
└── Asset upload automation

Homebrew Repository (deployment/homebrew)
├── Formula management + checksum updates
└── macOS distribution

Deployment Flow

1. Pre-flight Validation    → Environment checks, auth verification
2. Version Synchronization  → All repositories aligned
3. WebHapp Build            → Production-ready bundle
4. Release Creation         → GitHub release with webhapp
5. Kangaroo Update          → Copy webhapp, trigger CI/CD
6. Multi-Platform Builds    → Parallel builds across platforms
7. Asset Verification       → All binaries uploaded successfully
8. Cross-Repository Updates → Homebrew formula, documentation
9. Post-Release Validation  → Downloads tested, links verified

Templates and Automation

• GitHub Workflows: Optimized CI/CD pipeline templates
• Kangaroo Config: Production-ready desktop app configuration
• Deployment Config: Multi-environment configuration management
• Release Notes: Structured documentation templates
• Pre-flight Checks: Environment validation and prerequisites
• Rollback Procedures: Emergency recovery automation

Troubleshooting

• Asset Upload Failures: Builds complete but assets missing in release. Cause: electron-builder auto-publishing fails for branch builds. Fix: manual GitHub CLI uploads with wildcard patterns.
• Build Failures: Verify webhapp exists in pouch directory, check version sync across repos, ensure Nix environment, validate GitHub CLI auth.
• Repository Sync Issues: Submodules out of sync or version mismatches. Fix: proper git branch management and submodule updates.
• macOS: Code signing certificate management
• Windows: EV certificate configuration
• Linux: Post-install script permissions
• Recovery: Emergency rollback, partial release recovery, asset re-upload, repository resynchronization

Performance Metrics (v0.1.9)

• Platform Success Rate: 100% (5/5 platforms)
• Total Release Time: ~2.5 hours (including issue resolution)
• Build Retry Count: 1 retry (macOS upload fix)
• Asset Upload Success: 100% after manual pattern implementation

Best Practices

Release Management

1. Follow the 7-step process exactly
2. Use manual upload strategy over auto-publishing
3. Use wildcard file discovery to eliminate filename mismatch failures
4. Ensure cross-repository synchronization before starting

Build Optimization

1. Run all platform builds concurrently
2. Validate all uploads before proceeding
3. Use Nix for consistent build environments
4. Separate dev/test/prod configurations

Error Prevention

1. Run pre-flight validation before every release
2. Automate version synchronization
3. Have rollback procedures ready
4. Maintain comprehensive release notes
