4.2. Compliance Operator를 설치하는 정책 생성

네임스페이스, 서브스크립션 및 compliance-operator.yaml 이라는 OperatorGroup 매니페스트를 사용하여 YAML 파일을 생성합니다. 다음 예제에서는 이러한 매니페스트를 compliance-operator 네임스페이스에 설치합니다.

apiVersion: v1
kind: Namespace
metadata:
  name: openshift-compliance
---
apiVersion: operators.coreos.com/v1
kind: OperatorGroup
metadata:
  name: compliance-operator
  namespace: openshift-compliance
spec:
  targetNamespaces:
    - openshift-compliance
---
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: compliance-operator
  namespace: openshift-compliance
spec:
  channel: release-0.1
  name: compliance-operator
  source: redhat-operators
  sourceNamespace: openshift-marketplace

PolicyGenerator 구성 파일을 생성합니다. 모든 OpenShift Container Platform 관리 클러스터에 Compliance Operator를 설치하는 다음 PolicyGenerator 정책 예를 확인합니다.

apiVersion: policy.open-cluster-management.io/v1
kind: PolicyGenerator
metadata:
  name: install-compliance-operator
policyDefaults:
  namespace: policies
  placement:
    labelSelector:
      matchExpressions:
        - key: vendor
          operator: In
          values:
            - "OpenShift"
policies:
  - name: install-compliance-operator
    manifests:
      - path: compliance-operator.yaml

kustomization.yaml 파일에 정책 생성기를 추가합니다. generators 섹션은 다음 구성과 유사할 수 있습니다.

generators:
  - policy-generator-config.yaml

결과적으로 생성된 정책은 다음 파일과 유사합니다.

apiVersion: cluster.open-cluster-management.io/v1beta1
kind: Placement
metadata:
  name: placement-install-compliance-operator
  namespace: policies
spec:
  predicates:
  - requiredClusterSelector:
      labelSelector:
        matchExpressions:
        - key: vendor
          operator: In
          values:
          - OpenShift
