🚀 Quick Release Guide

Automated Release (Recommended)

# 1. Create a complete release with changelog and GitHub release
./scripts/version-manager.sh release --version v1.2.3 --changelog --github-release

# 2. For pre-releases
./scripts/version-manager.sh release --version v1.2.3-rc.1 --pre-release --changelog --github-release

Manual Release Steps

1. Prepare Release
2. Create Tag

5. Verify Deployment

📋 Detailed Release Process

1. Pre-Release Checklist

Before starting any release, ensure:

• All tests pass in CI/CD
• Database migrations tested and documented
• Docker images build successfully
• Documentation updated with new features
• Breaking changes documented (if any)
• Security vulnerabilities addressed
• Performance regressions checked

2. Release Preparation

Check Current Status

# Check current version and status
./scripts/version-manager.sh status

# Check for uncommitted changes
git status

# Ensure you're on main branch
git checkout main
git pull origin main

Version Selection

Follow Semantic Versioning:

• Major (v2.0.0): Breaking changes, major new features
• Minor (v1.1.0): New features, backward compatible
• Patch (v1.0.1): Bug fixes, backward compatible
• Pre-release (v1.0.0-rc.1): Release candidates, beta versions

Suggested Version

# Get version suggestion
./scripts/version-manager.sh suggest

3. Release Types

3.1 Standard Release

# Create standard release
./scripts/version-manager.sh release \
  --version v1.2.3 \
  --message "Release 1.2.3 with new features and bug fixes" \
  --changelog \
  --github-release

What this does:

1. Creates and pushes git tag
2. Generates changelog from commits
3. Creates GitHub release with changelog
4. Triggers Docker image build via GitHub Actions

3.2 Pre-Release

# Create pre-release (RC, beta, alpha)
./scripts/version-manager.sh release \
  --version v1.2.3-rc.1 \
  --message "Release candidate for 1.2.3" \
  --pre-release \
  --changelog \
  --github-release

3.3 Hotfix Release

# Create hotfix from main branch
git checkout main
git pull origin main

# Apply hotfix
git cherry-pick <hotfix-commit>

# Create hotfix release
./scripts/version-manager.sh release \
  --version v1.2.4 \
  --message "Hotfix: Critical security update" \
  --changelog \
  --github-release

4. Manual Release Steps

If you prefer manual control over the release process:

Step 1: Create Tag

# Create annotated tag
git tag -a v1.2.3 -m "Release 1.2.3"
git push origin v1.2.3

Step 2: Generate Changelog

# Generate changelog
python scripts/generate-changelog.py v1.2.3 --output CHANGELOG.md

# Review and edit changelog if needed
nano CHANGELOG.md

Step 3: Create GitHub Release

# Using GitHub CLI
gh release create v1.2.3 \
  --title "TimeTracker v1.2.3" \
  --notes-file CHANGELOG.md

# Or via GitHub web interface
# Go to: https://github.com/your-repo/releases/new

5. Post-Release Verification

5.1 Verify GitHub Actions

• Check that Docker build workflow completed successfully
• Verify Docker images are published to GHCR
• Confirm all CI/CD checks passed

5.2 Test Docker Images

# Test the released image
docker run -d --name test-release -p 8080:8080 \
  ghcr.io/drytrix/timetracker:v1.2.3

# Verify health
curl -f http://localhost:8080/_health

# Clean up
docker stop test-release && docker rm test-release

5.3 Update Documentation

• Update README.md version references
• Update deployment documentation
• Update Docker Compose examples
• Notify users of new release

6. Release Workflow Automation

The release process triggers several automated workflows:

6.1 Release Workflow (release.yml)

Triggered by: GitHub release creation or manual dispatch

Steps:

1. Validate Release - Ensures version format is correct
2. Run Tests - Full test suite with database migrations
3. Build & Push Docker - Multi-architecture Docker images
4. Generate Changelog - Automated changelog generation
5. Update Documentation - Version references in docs
6. Notify Deployment - Summary and deployment instructions

6.2 CI Workflow (ci.yml)

Triggered by: Push to main/develop, pull requests

Steps:

1. Lint & Format - Code quality checks
2. Test Database Migrations - PostgreSQL & SQLite testing
3. Test Docker Build - Container build and startup verification
4. Security Scan - Dependency and code security scanning
5. Version Management Validation - Version manager script testing

6.3 Migration Check Workflow (migration-check.yml)

Triggered by: Changes to models or migrations

Steps:

1. Validate Migrations - Schema consistency and rollback safety
2. Test with Sample Data - Data integrity verification
3. Generate Migration Report - Detailed migration analysis

7. Emergency Procedures

7.1 Rollback Release

# Delete tag locally and remotely
git tag -d v1.2.3
git push origin --delete v1.2.3

# Delete GitHub release
gh release delete v1.2.3

# Revert commits if needed
git revert <commit-hash>

7.2 Fix Broken Release

# Create hotfix
git checkout v1.2.3
git cherry-pick <fix-commit>

# Create new patch release
./scripts/version-manager.sh release \
  --version v1.2.4 \
  --message "Hotfix for v1.2.3 issues" \
  --changelog \
  --github-release

8. Release Schedule

Recommended Schedule

• Major releases: Every 6-12 months
• Minor releases: Every 1-2 months
• Patch releases: As needed for critical fixes
• Pre-releases: 1-2 weeks before major/minor releases

Release Windows

• Regular releases: Tuesday-Thursday (better for issue resolution)
• Hotfixes: Any day (emergency only)
• Pre-releases: Friday (allows weekend testing)

9. Communication

Internal Team

• Notify team before release
• Share release notes
• Coordinate deployment timing
• Plan post-release monitoring

External Users

• Update release notes on GitHub
• Update documentation website
• Notify via social media/newsletters
• Update Docker Hub descriptions

10. Quality Gates

Every release must pass:

• All automated tests (unit, integration, E2E)
• Database migration tests (up and down)
• Docker build verification (multi-architecture)
• Security scans (dependencies and code)
• Performance benchmarks (no significant regression)
• Documentation review (accuracy and completeness)

11. Troubleshooting

Common Issues

Issue: Docker build fails

# Check Docker build locally
docker build -t test-build .

# Check workflow logs in GitHub Actions

Issue: Migration validation fails

# Test migrations locally
flask db upgrade
flask db downgrade
flask db upgrade

Issue: Version tag already exists

# Check existing tags
git tag -l

# Delete if needed
git tag -d v1.2.3
git push origin --delete v1.2.3

12. Tools and Dependencies

Required Tools

• Git - Version control
• GitHub CLI (gh) - GitHub release management
• Docker - Container testing
• Python 3.11+ - Script execution
• Flask - Database migration testing

Installation

# Install GitHub CLI
# macOS: brew install gh
# Ubuntu: sudo apt install gh
# Windows: winget install GitHub.CLI

# Authenticate

13. Metrics and Monitoring

Track release metrics:

• Release frequency - How often releases are made
• Lead time - Time from commit to release
• Failure rate - Percentage of failed releases
• Recovery time - Time to fix broken releases
• User adoption - Docker pull statistics

14. Continuous Improvement

Regular review of:

• Release process efficiency
• Automation opportunities
• Quality gate effectiveness
• User feedback incorporation
• Tool and workflow updates
