2.10.10. AWS에서 보안 그룹 및 역할 생성
OpenShift Container Platform 클러스터에서 사용할 보안 그룹 및 역할을 AWS(Amazon Web Services)에서 생성해야 합니다.
제공된 CloudFormation 템플릿과 사용자 정의 매개변수 파일을 사용하여 AWS 리소스 스택을 생성할 수 있습니다. 스택은 OpenShift Container Platform 클러스터에 필요한 보안 그룹 및 역할을 나타냅니다.
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.
- AWS에서 VPC 및 관련 서브넷을 생성하고 구성하셨습니다.
프로세스
템플릿에 필요한 매개변수 값이 포함된 JSON 파일을 생성합니다.
[ { "ParameterKey": "InfrastructureName", 1 "ParameterValue": "mycluster-<random_string>" 2 }, { "ParameterKey": "VpcCidr", 3 "ParameterValue": "10.0.0.0/16" 4 }, { "ParameterKey": "PrivateSubnets", 5 "ParameterValue": "subnet-<random_string>" 6 }, { "ParameterKey": "VpcId", 7 "ParameterValue": "vpc-<random_string>" 8 } ]
- 1
- 클러스터에 대해 Ignition 구성 파일에 인코딩되는 클러스터 인프라의 이름입니다.
- 2
- Ignition 구성 파일 메타데이터에서 추출한 인프라 이름을
<cluster-name>-<random-string>
형식으로 지정합니다. - 3
- VPC의 CIDR 블록입니다.
- 4
xxxx/16-24
양식으로 정의하고 VPC에 사용한 CIDR 블록 매개변수를 지정합니다.- 5
- VPC용으로 만든 프라이빗 서브넷입니다.
- 6
- VPC에 대한 CloudFormation 템플릿의 출력에서
PrivateSubnetIds
값을 지정합니다. - 7
- 클러스터용으로 만든 VPC입니다.
- 8
- VPC에 대한 CloudFormation 템플릿의 출력에서
VpcId
값을 지정합니다.
- 이 항목의 보안 개체에 대한 CloudFormation 템플릿 섹션에서 템플릿을 복사하여 사용자 컴퓨터에 YAML 파일로 저장합니다. 이 템플릿은 클러스터에 필요한 보안 그룹 및 역할을 설명합니다.
CloudFormation 템플릿을 시작하여 보안 그룹 및 역할을 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 --capabilities CAPABILITY_NAMED_IAM 4
- 1
<name>
은 CloudFormation 스택의 이름입니다(예:cluster-sec)
. 클러스터를 제거하는 경우 이 스택의 이름이 필요합니다.- 2
<template>
은 저장한 CloudFormation 템플릿 YAML 파일의 상대 경로 및 이름입니다.- 3
<parameters>
는 CloudFormation 매개변수 JSON 파일의 상대 경로 및 이름입니다.- 4
- 제공된 템플릿에서 일부
AWS::IAM::Role
및AWS::IAM::InstanceProfile
리소스를 생성하므로CAPABILITY_NAMED_IAM
기능을 명시적으로 선언해야 합니다.
출력 예
arn:aws:cloudformation:us-east-1:269333783861:stack/cluster-sec/03bd4210-2ed7-11eb-6d7a-13fc0b61e9db
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.MasterSecurityGroupId
마스터 보안 그룹 ID
WorkerSecurityGroupId
작업자 보안 그룹 ID
MasterInstanceProfile
마스터 IAM 인스턴스 프로필
WorkerInstanceProfile
작업자 IAM 인스턴스 프로필
2.10.10.1. 보안 개체의 CloudFormation 템플릿
다음 CloudFormation 템플릿을 사용하여 OpenShift Container Platform 클러스터에 필요한 보안 개체를 배포할 수 있습니다.
