2.11.8. AWS에서 VPC 생성
OpenShift Container Platform 클러스터에서 사용할 VPC(Virtual Private Cloud)를 AWS(Amazon Web Services)에서 생성해야 합니다. VPN 및 라우팅 테이블 등 요구사항에 맞게 VPC를 사용자 지정할 수 있습니다.
제공된 CloudFormation 템플릿과 사용자 정의 매개변수 파일을 사용하여 VPC를 나타내는 AWS 리소스 스택을 생성할 수 있습니다.
AWS 인프라를 생성하는 데 제공된 CloudFormation 템플릿을 사용하지 않는 경우, 제공된 정보를 검토하고 수동으로 인프라를 생성해야 합니다. 클러스터가 올바르게 초기화되지 않은 경우, Red Hat 지원팀에 설치 로그를 제시하여 문의해야 할 수도 있습니다.
사전 요구 사항
- AWS 계정을 구성했습니다.
-
aws 구성
을 실행하여 AWS 키와 리전을 로컬 AWS 프로필에 추가하셨습니다. - 클러스터에 대한 Ignition 구성 파일을 생성하셨습니다.
프로세스
템플릿에 필요한 매개변수 값이 포함된 JSON 파일을 생성합니다.
[ { "ParameterKey": "VpcCidr", 1 "ParameterValue": "10.0.0.0/16" 2 }, { "ParameterKey": "AvailabilityZoneCount", 3 "ParameterValue": "1" 4 }, { "ParameterKey": "SubnetBits", 5 "ParameterValue": "12" 6 } ]
- 이 항목의 VPC 섹션에 대한 CloudFormation 템플릿섹션에서 템플릿을 복사하여 컴퓨터에 YAML 파일로 저장합니다. 이 템플릿은 클러스터에 필요한 VPC를 설명합니다.
CloudFormation 템플릿을 시작하여 VPC를 나타내는 AWS 리소스 스택을 생성합니다.
중요명령은 한 줄로 입력해야 합니다.
$ aws cloudformation create-stack --stack-name <name> 1 --template-body file://<template>.yaml 2 --parameters file://<parameters>.json 3
출력 예
arn:aws:cloudformation:us-east-1:269333783861:stack/cluster-vpc/dbedae40-2fd3-11eb-820e-12a48460849f
템플릿 구성 요소가 있는지 확인합니다.
$ aws cloudformation describe-stacks --stack-name <name>
StackStatus
에CREATE_COMPLETE
이 표시된 후 다음 매개변수의 출력 값이 표시됩니다. 클러스터를 생성하기 위해 실행하는 다른 CloudFormation 템플릿에 이러한 매개변수 값을 제공해야 합니다.VpcId
VPC의 ID입니다.
PublicSubnetIds
새 퍼블릭 서브넷의 ID입니다.
PrivateSubnetIds
새 프라이빗 서브넷의 ID입니다.
2.11.8.1. VPC용 CloudFormation 템플릿
다음 CloudFormation 템플릿을 사용하여 OpenShift Container Platform 클러스터에 필요한 VPC를 배포할 수 있습니다.
