# Amazon ECS에서 AWS CloudFormation 사용
<a name="ecs-with-cloudformation"></a>

Amazon ECS는 사용자가 정의한 템플릿을 사용하여 AWS 리소스를 모델링 및 설정하는 데 사용할 수 있는 서비스인 AWS CloudFormation과 통합됩니다. CloudFormation은 `YAML` 또는 `JSON` 형식의 텍스트 파일인 **템플릿**을 사용합니다. 템플릿은 생성하려는 AWS 리소스의 블루프린트와 같습니다. 템플릿을 생성하고 제출하면 CloudFormation이 **스택**을 생성합니다. 템플릿에서 정의한 리소스를 스택을 통해 관리합니다. 리소스를 생성, 업데이트 또는 삭제하려는 경우 해당 리소스에서 생성된 스택을 생성, 업데이트 또는 삭제합니다. 스택을 업데이트할 때는 먼저 **변경 세트**를 생성해야 합니다. 변경 세트는 변경을 적용하기 전에 그 영향을 받는 항목을 보여줍니다. 그러면 예를 들어 데이터베이스 이름을 변경하여 실수로 데이터베이스를 삭제하는 경우를 방지할 수 있습니다. 템플릿, 스택 및 변경 세트에 대한 자세한 내용은 *AWS CloudFormation 사용 설명서*의 [CloudFormation 작동 방식](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cloudformation-overview.html#cfn-concepts-stacks)을 참조하세요.

CloudFormation을 사용하여 리소스 및 인프라를 생성하고 관리하는 데 소요되는 시간을 줄일 수 있습니다. Amazon ECS 클러스터, 태스크 정의, 서비스 등 원하는 모든 AWS 리소스를 설명하는 템플릿을 생성할 수 있습니다. 그런 다음 CloudFormation은 해당 리소스를 프로비저닝하고 구성합니다.

또한 CloudFormation을 사용하면 템플릿을 재사용하여 Amazon ECS 리소스를 일관되고 반복적으로 설정할 수 있습니다. 리소스를 한 번 설명한 후 여러 AWS 계정 및 AWS 리전 간에 동일한 리소스를 다시 프로비저닝할 수 있습니다.

CloudFormation 템플릿을 AWS Management Console 또는 AWS Command Line Interface와 함께 사용하여 리소스를 생성할 수 있습니다.

CloudFormation에 대한 자세한 내용은 다음 리소스를 참조하세요.

# CloudFormation 콘솔을 사용하여 Amazon ECS 리소스 생성
<a name="ecs-cloudformation-console"></a>

CloudFormation에서 Amazon ECS를 사용하는 한 가지 방법은 AWS Management Console을 사용하는 것입니다. 여기에서 태스크 정의, 클러스터, 서비스와 같은 Amazon ECS 구성 요소를 위한 CloudFormation 스택을 생성하고 콘솔에서 직접 배포할 수 있습니다. 다음 자습서에서는 CloudFormation 콘솔을 사용하여 템플릿을 통해 Amazon ECS 리소스를 생성하는 방법을 보여줍니다.

## 사전 조건
<a name="ecs-cloudformation-console-prerequisites"></a>

이 자습서에서는 다음 사전 조건이 충족되었다고 가정합니다.
+ [Amazon ECS 사용 설정](get-set-up-for-amazon-ecs.md)의 단계가 완료되었습니다.
+ IAM 사용자는 [AmazonECS\$1FullAccess](security-iam-awsmanpol.md#security-iam-awsmanpol-AmazonECS_FullAccess) IAM 정책 예제에 지정된 필수 권한을 가집니다.

## 1단계: 스택 템플릿 생성
<a name="ecs-cloudformation-create-template-file"></a>

다음 단계를 사용하여 Amazon ECS 서비스 및 기타 관련 리소스를 위한 CloudFormation 스택 템플릿을 생성합니다.

1. 원하는 텍스트 편집기를 사용하여 `ecs-tutorial-template.yaml`이라는 파일을 생성합니다.

1. `ecs-tutorial-template.yaml` 파일에 다음 템플릿을 붙여 넣고 변경 사항을 저장합니다.

    이 자습서에서 사용되는 템플릿은 Fargate에서 실행되는 두 가지 태스크로 Amazon ECS 서비스를 생성합니다. 각 태스크는 샘플 Amazon ECS 애플리케이션을 실행합니다. 또한 템플릿은 애플리케이션 트래픽을 분산하는 Application Load Balancer와 CPU 사용률을 기반으로 애플리케이션을 확장하는 Application Auto Scaling 정책을 생성합니다. 또한 템플릿은 애플리케이션을 배포하는 데 필요한 네트워킹 리소스, 컨테이너 로그에 대한 로깅 리소스 및 Amazon ECS 태스크 실행 IAM 역할을 생성합니다. 태스크 실행 역할에 대한 자세한 정보는 [Amazon ECS 태스크 실행 IAM 역할](task_execution_IAM_role.md) 섹션을 참조하세요. 오토 스케일링에 대한 자세한 내용은 [Amazon ECS 서비스 자동 조정](service-auto-scaling.md) 섹션을 참조하세요.

## 2단계: Amazon ECS 리소스를 위한 스택 생성
<a name="ecs-cloudformation-create-stack"></a>

템플릿 파일을 생성한 후 CloudFormation 콘솔을 사용하여 다음 단계에 따라 템플릿으로 스택을 생성할 수 있습니다.

CloudFormation 콘솔을 사용하여 스택을 생성하는 방법에 대한 자세한 내용은 *AWS CloudFormation 사용 설명서*의 [CloudFormation 콘솔에서 스택 생성](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-console-create-stack.html)을 참조하고 다음 테이블을 통해 지정할 옵션을 결정합니다.


| 옵션 | 값 | 
| --- | --- | 
|  사전 조건 - 템플릿 준비  | 기존 템플릿 선택 | 
| 템플릿 지정 |  템플릿 파일 업로드  | 
| 파일 선택 |  ecs-tutorial-template.yaml  | 
| 스택 이름 |  ecs-tutorial-stack  | 
| 파라미터 |  모든 파라미터를 기본값으로 둡니다.  | 
| 기능 |  CloudFormation의 IAM 리소스 생성을 승인하려면 **이 템플릿이 IAM 리소스를 생성할 수 있음을 승인합니다**를 선택합니다.  | 

## 3단계: 확인
<a name="ecs-cloudformation-verify"></a>

다음 단계에 따라 제공된 템플릿을 사용한 Amazon ECS 리소스 생성을 확인합니다.

스택 정보 및 리소스를 보는 방법에 대한 자세한 내용은 *AWS CloudFormation 사용 설명서*의 [ CloudFormation 콘솔에서 스택 정보 보기](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-console-view-stack-data-resources.html)를 참조하고 다음 테이블을 통해 확인할 사항을 결정합니다.


| 스택 세부 정보 필드 | 확인할 항목 | 
| --- | --- | 
|  스택 정보  | 상태는 CREATE\$1COMPLETE입니다. | 
| 리소스 |  서비스 콘솔에 대한 링크가 포함된 생성된 리소스 목록입니다. Amazon ECS 콘솔에서 생성된 서비스, 클러스터 및 태스크 정의에 대한 자세한 내용을 보려면 `ECSCluster`, `ECSService`, `TaskDefinition`에 대한 링크를 선택합니다.  | 
| 출력 |  **LoadBalancerURL**. 웹 브라우저에 URL을 붙여넣어 샘플 Amazon ECS 애플리케이션을 표시하는 웹 페이지를 봅니다.  | 

## 4단계: 리소스 정리
<a name="ecs-cloudformation-console-cleanup"></a>

리소스를 정리하고 추가 비용이 발생하지 않도록 하려면 *CloudFormation 사용 설명서*의 [ CloudFormation 콘솔에서 스택 삭제](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-console-delete-stack.html)의 단계를 따르세요.

# AWS CLI용 CloudFormation 명령을 사용하여 Amazon ECS 리소스 생성
<a name="ecs-cloudformation-cli"></a>

CloudFormation에서 Amazon ECS를 사용하는 한 가지 방법은 AWS CLI를 사용하는 것입니다. 태스크 정의, 클러스터, 서비스와 같은 Amazon ECS 구성 요소를 위한 CloudFormation 스택을 생성하고 배포할 수 있습니다. 다음 자습서에서는 AWS CLI를 사용하여 CloudFormation 템플릿을 통해 Amazon ECS 리소스를 생성하는 방법을 보여줍니다.

## 사전 조건
<a name="ecs-cloudformation-cli-prerequisite"></a>
+ [Amazon ECS 사용 설정](get-set-up-for-amazon-ecs.md)의 단계가 완료되었습니다.
+ IAM 사용자는 [AmazonECS\$1FullAccess](security-iam-awsmanpol.md#security-iam-awsmanpol-AmazonECS_FullAccess) IAM 정책 예제에 지정된 필수 권한을 가집니다.

## 1단계: 스택 생성
<a name="ecs-cloudformation-cli-create"></a>

`ecs-tutorial-template.yaml` 파일에 저장된 AWS CLI를 사용하여 스택을 생성하려면 다음 명령을 실행합니다.

 이 자습서에서 사용되는 템플릿은 Fargate에서 실행되는 두 가지 태스크로 Amazon ECS 서비스를 생성합니다. 각 태스크는 샘플 Amazon ECS 애플리케이션을 실행합니다. 또한 템플릿은 애플리케이션 트래픽을 분산하는 Application Load Balancer와 CPU 사용률을 기반으로 애플리케이션을 확장하는 Application Auto Scaling 정책을 생성합니다. 또한 템플릿은 애플리케이션을 배포하는 데 필요한 네트워킹 리소스, 컨테이너 로그에 대한 로깅 리소스 및 Amazon ECS 태스크 실행 IAM 역할을 생성합니다. 태스크 실행 역할에 대한 자세한 정보는 [Amazon ECS 태스크 실행 IAM 역할](task_execution_IAM_role.md) 섹션을 참조하세요. 오토 스케일링에 대한 자세한 내용은 [Amazon ECS 서비스 자동 조정](service-auto-scaling.md) 섹션을 참조하세요.

템플릿 파일을 생성한 후 다음 명령을 사용하여 스택을 생성합니다. `--capabilities` 플래그는 템플릿에 지정된 대로 Amazon ECS 태스크 실행 역할을 생성하는 데 필요합니다. `--parameters` 플래그를 지정하여 템플릿 파라미터를 사용자 지정할 수도 있습니다.

```
aws cloudformation create-stack \
      --stack-name ecs-tutorial-stack \
      --template-body file://ecs-tutorial-template.yaml \
      --region aws-region \
      --capabilities CAPABILITY_NAMED_IAM
```

`create-stack` 명령을 실행한 후 `describe-stacks`를 사용하여 스택 생성 상태를 확인할 수 있습니다.

```
aws cloudformation describe-stacks \
      --stack-name ecs-tutorial-stack \
      --region aws-region
```

## 2단계: Amazon ECS 리소스 생성 확인
<a name="ecs-cloudformation-cli-verify"></a>

Amazon ECS 리소스가 올바르게 생성되었는지 확인하려면 다음 단계를 수행합니다.

1. 다음 명령을 실행하여 AWS 리전의 모든 태스크 정의를 나열합니다.

   ```
   aws ecs list-task-definitions
   ```

   이 명령은 태스크 정의 Amazon 리소스 이름(ARN) 목록을 반환합니다. 템플릿을 사용하여 생성한 태스크 정의의 ARN은 다음 형식으로 표시됩니다.

   ```
   {
       "taskDefinitionArns": [
        .....
           "arn:aws:ecs:aws-region:111122223333:task-definition/ecs-tutorial-stack-task:1",
        .....   
       ]
   }
   ```

1. 다음 명령을 실행하여 AWS 리전의 모든 클러스터를 나열합니다.

   ```
   aws ecs list-clusters
   ```

   이 명령은 클러스터 ARN 목록을 반환합니다. 템플릿을 사용하여 생성한 클러스터의 ARN은 다음 형식으로 표시됩니다.

   ```
   {
       "clusterArns": [
           .....
           "arn:aws:ecs:aws-region:111122223333:cluster/ecs-tutorial-stack-cluster",
           .....
       ]
   }
   ```

1. 다음 명령을 실행하여 클러스터 `ecs-tutorial-stack-cluster`의 모든 서비스를 나열합니다.

   ```
   aws ecs list-services \
         --cluster ecs-tutorial-stack-cluster
   ```

   이 명령은 서비스 ARN 목록을 반환합니다. 템플릿을 사용하여 생성한 서비스의 ARN은 다음 형식으로 표시됩니다.

   ```
   {
       "serviceArns": [
           "arn:aws:ecs:aws-region:111122223333:service/ecs-tutorial-stack-cluster/ecs-tutorial-stack-service"
       ]
   }
   ```

생성된 Application Load Balancer의 DNS 이름을 가져와 리소스 생성을 확인하는 데 사용할 수도 있습니다. DNS 이름을 가져오려면 다음 명령을 실행합니다.

 다음 명령을 실행하여 생성된 스택의 결과를 검색합니다.

```
aws cloudformation describe-stacks \
  --stack-name ecs-tutorial-stack \
  --region aws-region \
  --query 'Stacks[0].Outputs[?OutputKey==`LoadBalancerURL`].OutputValue' \
  --output  text
```

출력:

```
http://ecs-tutorial-stack-alb-0123456789.aws-region.elb.amazonaws.com
```

DNS 이름을 브라우저에 붙여넣어 샘플 Amazon ECS 애플리케이션을 표시하는 웹 페이지를 봅니다.

## 3단계: 정리
<a name="ecs-cloudformation-cli-cleanup"></a>

생성한 리소스를 정리하려면 다음 명령을 실행합니다.

```
aws cloudformation delete-stack \
      --stack-name ecs-stack
```

`delete-stack` 명령은 이 자습서에서 생성된 CloudFormation 스택의 삭제를 시작하여 스택의 모든 리소스를 삭제합니다. 삭제를 확인하려면 [2단계: Amazon ECS 리소스 생성 확인](#ecs-cloudformation-cli-verify)의 절차를 반복하면 됩니다. 출력의 ARN 목록에는 더 이상 `ecs-tutorial-stack-task`이라는 태스크 정의 또는 `ecs-tutorial-stack-cluster`라는 클러스터가 포함되지 않습니다. `list-services` 호출이 실패합니다.

# Amazon ECS용 CloudFormation 템플릿 예제
<a name="working-with-templates"></a>

CloudFormation를 사용하여 Amazon ECS 클러스터, 태스크 정의 및 서비스를 생성할 수 있습니다. 다음 주제에는 다양한 구성으로 리소스를 생성하는 방법을 보여주는 템플릿이 포함되어 있습니다. CloudFormation 콘솔 또는 AWS CLI에서 이러한 템플릿을 사용하여 이러한 리소스를 생성할 수 있습니다.

 CloudFormation 템플릿은 CloudFormation 스택에서 프로비저닝할 리소스를 설명하는 JSON 또는 YAML 형식 텍스트 파일입니다. JSON 또는 YAML 형식에 익숙하지 않은 경우 AWS Infrastructure Composer를 사용하여 CloudFormation 템플릿을 시작할 수 있습니다. 자세한 내용은 *AWS CloudFormation 사용 설명서*의 [Infrastructure Composer를 사용하여 시각적으로 템플릿 생성](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/infrastructure-composer-for-cloudformation.html)을 참조하세요.

다음 주제에서는 Amazon ECS 태스크 정의, 클러스터 및 서비스용 예제 템플릿을 제공합니다.

## 용량 공급자
<a name="create-capacity-providers"></a>

용량 공급자는 Amazon ECS 클러스터와 연결되며 워크로드의 컴퓨팅 용량을 관리하는 데 사용됩니다.

### Amazon ECS 관리형 인스턴스에 대한 용량 공급자 생성
<a name="create-managed-instances-capacity-provider"></a>

 기본적으로 Amazon ECS는 가장 비용 최적화된 범용 인스테이스 유형을 자동으로 선택하는 용량 공급자를 제공합니다. 그러나 사용자 지정 용량 공급자를 생성하여 인스턴스 유형, CPU 제조업체, 액셀러레이터 유형 및 기타 요구 사항과 같은 인스턴스 요구 사항을 지정할 수 있습니다. 다음 템플릿을 사용하여 지정된 메모리 및 CPU 요구 사항을 충족하는 Amazon ECS 관리형 인스턴스의 용량 공급자를 생성할 수 있습니다.

## 서비스
<a name="create-service"></a>

Amazon ECS 서비스를 사용하면 Amazon ECS 클러스터에서 지정된 수의 태스크 정의 인스턴스를 동시에 실행하고 유지 관리할 수 있습니다. 태스크가 실패하거나 중지되면 Amazon ECS 서비스 스케줄러가 태스크 정의의 다른 인스턴스를 시작하여 해당 태스크를 대체합니다. 이렇게 하면 서비스에서 원하는 수의 태스크를 유지 관리하는 데 도움이 됩니다. 다음 템플릿을 사용하여 서비스를 배포할 수 있습니다. Amazon ECS 서비스에 대한 자세한 내용은 [Amazon ECS 서비스](ecs_services.md) 섹션을 참조하세요.

### 로드 밸런싱된 웹 애플리케이션 배포
<a name="simple-service"></a>

 다음 템플릿은 Fargate에서 실행되는 두 가지 태스크로 Amazon ECS 서비스를 생성합니다. 각 태스크에는 NGINX 컨테이너가 있습니다. 또한 템플릿은 애플리케이션 트래픽을 분산하는 Application Load Balancer와 CPU 사용률을 기반으로 애플리케이션을 확장하는 Application Auto Scaling 정책을 생성합니다. 또한 템플릿은 애플리케이션을 배포하는 데 필요한 네트워킹 리소스, 컨테이너 로그에 대한 로깅 리소스 및 Amazon ECS 태스크 실행 IAM 역할을 생성합니다. 태스크 실행 역할에 대한 자세한 정보는 [Amazon ECS 태스크 실행 IAM 역할](task_execution_IAM_role.md) 섹션을 참조하세요. 오토 스케일링에 대한 자세한 내용은 [Amazon ECS 서비스 자동 조정](service-auto-scaling.md) 섹션을 참조하세요.

### Amazon VPC Lattice를 사용하는 서비스 배포
<a name="service-vpc-lattice"></a>

다음 템플릿을 사용하여 VPC Lattice를 사용하는 Amazon ECS 서비스의 생성을 시작할 수 있습니다. VPC Lattice를 설정하려면 추가로 다음 단계를 완료해야 할 수 있습니다.
+ 인바운드 규칙 `vpc-lattice` 접두사를 허용하고 포트 80에서 트래픽을 허용하도록 보안 그룹의 VPC Lattice에 대한 인바운드 규칙을 업데이트합니다.
+ 서비스의 VPC를 VPC Lattice 서비스 네트워크에 연결합니다.
+ Amazon Route 53을 사용하여 프라이빗 또는 퍼블릭 호스팅 영역을 구성합니다.
+ VPC Lattice 서비스에서 리스너 및 리스너 규칙을 구성합니다.
+ 대상 그룹의 상태 확인 구성을 확인합니다.

Amazon VPC에서 VPC Lattice를 사용하는 방법에 대한 자세한 내용은 [Amazon VPC Lattice를 사용하여 Amazon ECS 서비스 연결, 관찰 및 보안 유지](ecs-vpc-lattice.md) 섹션을 참조하세요.

## Amazon ECS에 대한 IAM 역할
<a name="ecs-cloudformation-iam-roles"></a>

CloudFormation 템플릿을 사용하여 Amazon ECS에서 사용할 IAM 역할을 생성할 수 있습니다. Amazon ECS용 IAM 역할에 대한 자세한 내용은 [Amazon ECS에 대한 IAM 역할](security-ecs-iam-role-overview.md) 섹션을 참조하세요.

### Amazon ECS 작업 실행 역할
<a name="ecs-cloudformation-iam-roles-task-execution"></a>

태스크 실행 IAM 역할은 Amazon ECS 컨테이너 에이전트 및 Fargate 에이전트에 사용자를 대신하여 AWS API 호출을 수행할 권한을 부여합니다. 태스크의 요구 사항에 따라 이 역할이 필요합니다. 자세한 내용은 [Amazon ECS 태스크 실행 IAM 역할](task_execution_IAM_role.md) 섹션을 참조하세요.

다음 템플릿을 사용하여 `AmazonECSTaskExecutionRolePolicy` 관리형 정책을 사용하는 간단한 태스크 실행 역할을 생성할 수 있습니다.
