# 7. 정리 (Cleanup)

실습이 끝나면 비용이 발생하지 않도록 리소스를 삭제합니다.

***

### 7.1 OSMO Helm 릴리스 삭제

```bash
helm uninstall osmo-minimal -n osmo-minimal
helm uninstall osmo-operator -n osmo-operator
helm uninstall kai-scheduler -n kai-scheduler
```

***

### 7.2 네임스페이스 삭제

```bash
kubectl delete namespace osmo-minimal osmo-operator osmo-workflows kai-scheduler
```

***

### 7.3 IAM 리소스 정리

```bash
# Access Key 삭제
ACCESS_KEY_ID=$(aws iam list-access-keys --user-name osmo-workflow-user \
  --query 'AccessKeyMetadata[0].AccessKeyId' --output text)
aws iam delete-access-key --user-name osmo-workflow-user --access-key-id $ACCESS_KEY_ID

# Policy 삭제
aws iam delete-user-policy --user-name osmo-workflow-user --policy-name osmo-s3-access

# 사용자 삭제
aws iam delete-user --user-name osmo-workflow-user
```

***

### 7.4 CDK 스택 삭제

```bash
cd ~/aws-physical-ai-recipes/osmo/cdk
npx cdk destroy --context region=us-west-2
```

{% hint style="info" %}
CDK destroy는 약 15분 소요됩니다. EKS 클러스터 삭제가 가장 오래 걸립니다.
{% endhint %}

***

### 7.5 삭제 확인

```bash
# CloudFormation 스택이 삭제되었는지 확인
aws cloudformation describe-stacks --stack-name Osmo --region us-west-2 2>&1 | grep -q "does not exist" && echo "삭제 완료"
```

{% hint style="warning" %}
`cdk destroy` 실패 시, AWS 콘솔 → CloudFormation에서 스택을 수동 삭제하세요. 특히 S3 버킷이 비어있지 않으면 삭제가 실패할 수 있습니다. 이 경우 버킷을 먼저 비운 후 재시도합니다.
{% endhint %}
