## スモークテスト結果

| テスト | ステータス |
|------|--------|
| ヘルスエンドポイント | $(curl -f -s --max-time 5 "$DEPLOY_URL/health" > /dev/null 2>&1 && echo "✅ 合格" || echo "❌ 不合格") |

| データベース接続性 | $(curl -f -s --max-time 5 "$DEPLOY_URL/api/db-check" > /dev/null 2>&1 && echo "✅ 合格" || echo "❌ 不合格") |

## ロールバック手順

問題が検出された場合、以下でロールバック：

\`\`\`bash
# Vercel
vercel rollback <deployment-url>

# Kubernetes
kubectl rollout undo deployment/<deployment-name> -n <namespace>

# Docker / Docker Compose
docker-compose down && git checkout <previous-commit> && docker-compose up -d

# Heroku
heroku releases:rollback -a <app-name>
\`\`\`

## 監視

- **ログ：** \`kubectl logs -f deployment/<name>\` またはロギングサービスを確認
- **メトリクス：** Datadog/Grafana/CloudWatchダッシュボードを確認
- **エラー：** Sentry/エラートラッキングサービスを監視
- **パフォーマンス：** レスポンスタイムとエラー率を確認

## 次のステップ

- [ ] 今後30分間エラー率を監視
- [ ] ユーザー向け機能を手動確認
- [ ] アナリティクス/トラッキングが機能していることを確認
- [ ] チームチャンネルでデプロイをアナウンス
- [ ] リリースノートを更新

## Smoke Test Results

| Test | Status |
|------|--------|
| Health Endpoint | $(curl -f -s --max-time 5 "$DEPLOY_URL/health" > /dev/null 2>&1 && echo "✅ Pass" || echo "❌ Fail") |
| API Endpoints | $(curl -f -s --max-time 5 "$DEPLOY_URL/api/status" > /dev/null 2>&1 && echo "✅ Pass" || echo "❌ Fail") |
| Database Connectivity | $(curl -f -s --max-time 5 "$DEPLOY_URL/api/db-check" > /dev/null 2>&1 && echo "✅ Pass" || echo "❌ Fail") |

## Rollback Procedure

If issues are detected, rollback using:

\`\`\`bash
# Vercel
vercel rollback <deployment-url>

# Kubernetes
kubectl rollout undo deployment/<deployment-name> -n <namespace>

# Docker / Docker Compose
docker-compose down && git checkout <previous-commit> && docker-compose up -d

# Heroku
heroku releases:rollback -a <app-name>
\`\`\`

## Monitoring

- **Logs:** \`kubectl logs -f deployment/<name>\` or check your logging service
- **Metrics:** Check Datadog/Grafana/CloudWatch dashboards
- **Errors:** Monitor Sentry/error tracking service
- **Performance:** Check response times and error rates

## Next Steps

- [ ] Monitor error rates for next 30 minutes
- [ ] Check user-facing features manually
- [ ] Verify analytics/tracking is working
- [ ] Announce deployment in team channel
- [ ] Update release notes
