Story 4.1 Implementation Summary

Status: COMPLETE

Overview

Successfully implemented deployment of generated content to Bunny.net cloud storage with tier-segregated URL logging and automatic deployment after batch generation.

Implementation Details

1. Bunny.net Storage Client (src/deployment/bunny_storage.py)

• BunnyStorageClient class for uploading files to Bunny.net storage zones
• Uses per-zone storage_zone_password from database for authentication
• Region-aware URL generation:
  • Frankfurt (DE): storage.bunnycdn.com (no prefix)
  • Other regions: {region}.storage.bunnycdn.com (e.g., la.storage.bunnycdn.com)
• Uses application/octet-stream content-type per Bunny.net API requirements
• Implements retry logic with exponential backoff (3 attempts)
• Methods:
  • upload_file(): Upload HTML content to storage zone
  • file_exists(): Check if file exists in storage
  • list_files(): List files in storage zone
• Tested with real Bunny.net storage - successful upload verified

2. Database Updates

• Added deployed_url (TEXT, nullable) to generated_content table
• Added deployed_at (TIMESTAMP, nullable, indexed) to generated_content table
• Created migration script: scripts/migrate_add_deployment_fields.py
• Added repository methods:
  • GeneratedContentRepository.mark_as_deployed(): Update deployment status
  • GeneratedContentRepository.get_deployed_content(): Query deployed articles

3. URL Logger (src/deployment/url_logger.py)

• URLLogger class for tier-segregated URL logging
• Creates daily log files in deployment_logs/ directory:
  • YYYY-MM-DD_tier1_urls.txt for Tier 1 articles
  • YYYY-MM-DD_other_tiers_urls.txt for Tier 2+ articles
• Automatic duplicate prevention by reading existing URLs before appending
• Boilerplate pages (about, contact, privacy) are NOT logged

4. URL Generation (src/generation/url_generator.py)

Extended with new functions:

• generate_public_url(): Create full HTTPS URL from site + file path
• generate_file_path(): Generate storage path for articles (slug-based)
• generate_page_file_path(): Generate storage path for boilerplate pages

5. Deployment Service (src/deployment/deployment_service.py)

• DeploymentService class orchestrates deployment workflow
• deploy_batch(): Deploy all content for a project
  • Uploads articles with formatted_html
  • Uploads boilerplate pages (about, contact, privacy)
  • Logs article URLs to tier-segregated files
  • Updates database with deployment status and URLs
  • Returns detailed statistics
• deploy_article(): Deploy single article
• deploy_boilerplate_page(): Deploy single boilerplate page
• Continues on error by default (configurable)

6. CLI Command (src/cli/commands.py)

Added deploy-batch command:

uv run python -m src.cli deploy-batch \
  --batch-id 123 \
  --admin-user admin \
  --admin-password mypass

Options:

• --batch-id (required): Project/batch ID to deploy
• --admin-user / --admin-password: Authentication
• --continue-on-error: Continue if file fails (default: True)
• --dry-run: Preview what would be deployed

7. Automatic Deployment Integration (src/generation/batch_processor.py)

• Added auto_deploy parameter to process_job() (default: True)
• Deployment triggers automatically after all tiers complete
• Uses same DeploymentService as manual CLI command
• Graceful error handling (logs warning, continues batch processing)
• Can be disabled via auto_deploy=False for testing

8. Configuration (src/core/config.py)

• Added get_bunny_storage_api_key() validation function
• Checks for BUNNY_API_KEY in .env file
• Clear error messages if keys are missing

9. Testing (tests/integration/test_deployment.py)

Comprehensive integration tests covering:

• URL generation and slug creation
• Tier-segregated URL logging with duplicate prevention
• Bunny.net storage client uploads
• Deployment service (articles, pages, batches)
• All 13 tests passing

File Structure

deployment_logs/
  YYYY-MM-DD_tier1_urls.txt          # Tier 1 article URLs
  YYYY-MM-DD_other_tiers_urls.txt    # Tier 2+ article URLs

src/deployment/
  bunny_storage.py                    # Storage upload client
  deployment_service.py               # Main deployment orchestration
  url_logger.py                       # Tier-segregated URL logging

scripts/
  migrate_add_deployment_fields.py    # Database migration

tests/integration/
  test_deployment.py                  # Integration tests

Database Schema

ALTER TABLE generated_content ADD COLUMN deployed_url TEXT NULL;
ALTER TABLE generated_content ADD COLUMN deployed_at TIMESTAMP NULL;
CREATE INDEX idx_generated_content_deployed ON generated_content(deployed_at);

Usage Examples

Manual Deployment

# Deploy a specific batch
uv run python -m src.cli deploy-batch --batch-id 123 --admin-user admin --admin-password pass

# Dry run to preview
uv run python -m src.cli deploy-batch --batch-id 123 --dry-run

Automatic Deployment

# Generate batch with auto-deployment (default)
uv run python -m src.cli generate-batch --job-file jobs/my_job.json

# Generate without auto-deployment
# (Add --auto-deploy flag to generate-batch command if needed)

Key Design Decisions

1. Authentication: Uses per-zone storage_zone_password from database for uploads. No API key from .env needed for storage operations. The BUNNY_ACCOUNT_API_KEY is only for zone creation/management.
2. File Locking: Skipped for simplicity - duplicate prevention via file reading is sufficient
3. Auto-deploy Default: ON by default for convenience, can be disabled for testing
4. Continue on Error: Enabled by default to ensure partial deployments complete
5. URL Logging: Simple text files (one URL per line) for easy parsing by Story 4.2
6. Boilerplate Pages: Deploy stored HTML from site_pages.content (from Story 3.4)

Dependencies Met

• Story 3.1: Site assignment (articles have site_deployment_id)
• Story 3.3: Content interlinking (HTML is finalized)
• Story 3.4: Boilerplate pages (SitePage table exists)

Environment Variables Required

BUNNY_ACCOUNT_API_KEY=your_account_api_key_here  # For zone creation (already existed)

Important: File uploads do NOT use an API key from .env. They use the per-zone storage_zone_password stored in the database (in the site_deployments table). This password is set automatically when zones are created via provision-site or sync-sites commands.

Testing Results

All 18 tests passing:

• URL generation (4 tests)
• URL logging (4 tests)
• Storage client (2 tests)
• Deployment service (3 tests)
• Storage URL generation (5 tests - including DE region special case)

Real-world validation: Successfully uploaded test file to Bunny.net storage and verified HTTP 201 response.

Known Limitations / Technical Debt

1. Only supports Bunny.net (multi-cloud deferred to future stories)
2. No CDN cache purging after deployment (Story 4.x)
3. No deployment verification/validation (Story 4.4)
4. URL logging is file-based (no database tracking)
5. Boilerplate pages stored as full HTML in DB (inefficient, works for now)

Next Steps

• Story 4.2: URL logging enhancements (partially implemented here)
• Story 4.3: Database status updates (partially implemented here)
• Story 4.4: Post-deployment verification
• Future: Multi-cloud support, CDN cache purging, parallel uploads

Notes

• Simple and reliable implementation prioritized over complex features
• Auto-deployment is the default happy path
• Manual CLI command available for re-deployment or troubleshooting
• Comprehensive error reporting for debugging
• All API keys managed via .env only (not master.config.json)
