9.13. AWS에서 Red Hat OpenShift용 cert-manager Operator 인증

프로세스

1. 다음과 같이 CredentialsRequest 리소스 YAML 파일을 생성합니다(예: sample-credential-request.yaml ).

   apiVersion: cloudcredential.openshift.io/v1
   kind: CredentialsRequest
   metadata:
     name: cert-manager
     namespace: openshift-cloud-credential-operator
   spec:
     providerSpec:
       apiVersion: cloudcredential.openshift.io/v1
       kind: AWSProviderSpec
       statementEntries:
       - action:
         - "route53:GetChange"
         effect: Allow
         resource: "arn:aws:route53:::change/*"
       - action:
         - "route53:ChangeResourceRecordSets"
         - "route53:ListResourceRecordSets"
         effect: Allow
         resource: "arn:aws:route53:::hostedzone/*"
       - action:
         - "route53:ListHostedZonesByName"
         effect: Allow
         resource: "*"
     secretRef:
       name: aws-creds
       namespace: cert-manager
     serviceAccountNames:
     - cert-manager

2. 다음 명령을 실행하여 CredentialsRequest 리소스를 생성합니다.

   $ oc create -f sample-credential-request.yaml

3. 다음 명령을 실행하여 cert-manager Operator for Red Hat OpenShift의 서브스크립션 오브젝트를 업데이트합니다.

   $ oc -n cert-manager-operator patch subscription openshift-cert-manager-operator --type=merge -p '{"spec":{"config":{"env":[{"name":"CLOUD_CREDENTIALS_SECRET_NAME","value":"aws-creds"}]}}}'

검증

1. 다음 명령을 실행하여 재배포된 cert-manager 컨트롤러 Pod의 이름을 가져옵니다.

   $ oc get pods -l app.kubernetes.io/name=cert-manager -n cert-manager

   출력 예

   NAME                          READY   STATUS    RESTARTS   AGE
   cert-manager-bd7fbb9fc-wvbbt  1/1     Running   0          15m39s

2. 다음 명령을 실행하여 cert-manager 컨트롤러 Pod가 mountPath 에 지정된 경로에 마운트된 AWS 인증 정보 볼륨으로 업데이트되었는지 확인합니다.

   $ oc get -n cert-manager pod/<cert-manager_controller_pod_name> -o yaml
