/deploy

Safe, automated deployments with built-in validation, health checks, and rollback capabilities.

Purpose

Handles deployment workflow including:

• Pre-deployment validation
• Build verification
• Security scanning
• Environment-specific deployment
• Post-deployment health checks
• Monitoring and rollback

Ensures safe deployments with comprehensive checks at every stage.

Usage

/deploy [environment]

Arguments

Argument	Description
staging	Deploy to staging environment
production	Deploy to production (requires confirmation)
preview	Deploy to preview/ephemeral environment

Workflow

Pre-Deploy Checks

Before any deployment, the command validates:

1. Build Verification

Python projects:

python -m build
python -m pytest

Node.js projects:

pnpm build
pnpm test

Validation:

• Build completes successfully
• No build warnings
• Build artifacts are generated
• Output size is reasonable

2. Run Tests

Executes full test suite:

# Python
pytest -v --cov=src --cov-report=term

# Node.js
pnpm test
pnpm test:e2e

Requirements:

• All tests pass
• Coverage meets threshold (80%+)
• No skipped tests
• E2E tests pass

3. Security Scan

Checks for vulnerabilities:

Node.js:

npm audit --audit-level=high
pnpm audit --audit-level=high

Python:

pip-audit
safety check

Validation:

• No high/critical vulnerabilities
• Dependencies are up to date
• No known security issues

4. Environment Verification

Staging:

• Staging branch is up to date
• No merge conflicts
• Environment variables configured

Production:

• Production branch matches main/master
• All PRs merged and approved
• Release notes prepared
• Rollback plan ready

Deploy Process

Staging Deployment

Automated deployment to staging:

# Build for staging
pnpm build:staging

# Deploy to staging environment
# (Implementation depends on your hosting)

Common platforms:

Vercel:

vercel deploy --prod=false

Cloudflare Pages:

wrangler pages deploy dist --project-name=app-staging

AWS:

aws deploy create-deployment \
  --application-name my-app \
  --deployment-group-name staging

Heroku:

git push heroku-staging main

Production Deployment

Requires explicit confirmation:

⚠️  Production Deployment
This will deploy to production environment.

Environment: production
Version: v1.2.3
Commits: 15 new commits since last deploy

Continue? (yes/no):

After confirmation:

# Tag release
git tag -a v1.2.3 -m "Release v1.2.3"
git push origin v1.2.3

# Build for production
pnpm build:production

# Deploy
# (Platform-specific deployment)

Post-Deploy Validation

After deployment, automated checks run:

1. Health Checks

# Check application health
curl https://app.example.com/health

# Expected response:
{
  "status": "healthy",
  "version": "v1.2.3",
  "timestamp": "2024-01-15T10:30:00Z"
}

2. Smoke Tests

Essential functionality tests:

• Homepage loads
• API endpoints respond
• Authentication works
• Database connection active
• Critical features functional

3. Monitor Logs

Watch for errors:

# Check recent logs
# (Platform-specific log viewing)

# Look for:
# - Error patterns
# - Performance issues
# - Unexpected warnings

Tips

Test on staging first: Always deploy to staging before production.

Use dry-run: Preview what will happen with --dry-run flag.

Monitor after deploy: Watch logs and metrics for at least 15 minutes after production deploys.

Have a rollback plan: Know how to quickly revert if issues occur.

Automate staging: Let staging deploy automatically, but keep production manual.

Tag releases: Use semantic versioning for production releases.

Update changelog: Keep changelog current with each production deployment.

Notify team: Alert team before production deployments.
