apiVersion: operator.ibm.com/v1alpha1
kind: OperandRequest
metadata:
  name: db2-instance1
  namespace: my-service
spec:
  requests:
  - registry: common-service
    namespace: ibm-common-services
    operands:
    - name: ibm-db2-operator
      kind: db2
      instanceName: db2-instance1
      spec:
         replicas: 3
    - name: ibm-db2-operator
      kind: db2
      instanceName: db2-instance2
      spec:
         replicas: 3

This CR will install DB2 operator and create two DB2 instances. db2-instance1 and db2-instance2 into namespace my-service
