# deployment-automation

> Deploy with confidence. Zero-downtime releases, instant rollback, and health checks that catch issues before users do.

## What It Does

- **Multi-strategy** — Blue-green, canary, or rolling deployments
- **Zero downtime** — Health checks before/after each step
- **Auto-rollback** — Instant revert on failure
- **Multi-env** — Dev → staging → production promotion
- **Notifications** — Slack, email, PagerDuty on deploy events

---

## Quick Start

```bash
# 1. Create deployment pipeline
node deploy.js pipeline create --name prod --stages build,test,deploy

# 2. Deploy with canary strategy
node deploy.js deploy --strategy canary --service api --canary-percent 10

# 3. Check deployment status
node deploy.js status --service api

# 4. Rollback if needed
node deploy.js rollback --service api --to previous
```

---

## Common Use Cases

### 🚀 Production Release
```bash
# Deploy with canary (10% traffic first)
node deploy.js deploy --strategy canary --service web --canary-percent 10

# Monitor for 10 minutes, then increase
node deploy.js canary --service web --percent 50
node deploy.js canary --service web --percent 100
```

### 🔄 Blue-Green Swap
```bash
# Deploy to green environment
node deploy.js deploy --strategy blue-green --service api

# Test green, then swap
node deploy.js swap --service api

# Instant rollback if issues
node deploy.js rollback --service api --to blue
```

### 🏥 Hotfix Emergency
```bash
# Deploy hotfix with extra verification
node deploy.js deploy --service api --ref hotfix-branch \
  --health-check-timeout 60s \
  --auto-rollback
```

### 📈 Promote Across Environments
```bash
# Promote staging to production
node deploy.js promote --from staging --to production --approve

# View config differences
node deploy.js diff --env staging vs production
```
