IBM Certified Administrator - Cloud Pak for Integration V2021.2 C1000-130 Question # 4 Topic 1 Discussion

When installing IBM Cloud Pak for Integration (CP4I) operators via the CLI, the Operator Lifecycle Manager (OLM) requires an OperatorGroup resource before applying a Subscription.

OperatorGroup defines the scope (namespace) in which the operator will be deployed and managed.

It ensures that the operator has the necessary permissions to install and operate in the specified namespace.

Without an OperatorGroup, the subscription for ibm-cp-integration cannot be applied, and the installation will fail.

Create a new namespace (if not already created):

Why an OperatorGroup is Required:Steps for CLI Installation:oc create namespace cp4i-namespace

Create the OperatorGroup YAML (e.g., operatorgroup.yaml):

apiVersion: operators.coreos.com/v1

kind: OperatorGroup

metadata:

name: cp4i-operatorgroup

namespace: cp4i-namespace

spec:

targetNamespaces:

- cp4i-namespace

Apply it using:

oc apply -f operatorgroup.yaml

Apply the Subscription YAML for ibm-cp-integration once the OperatorGroup exists.

B. The ibm-foundational-services operator and subscription

While IBM Foundational Services is required for some Cloud Pak features, its absence does not prevent the creation of an operator subscription.

C. The platform-navigator operator and subscription

Platform Navigator is an optional component and is not required before installing the ibm-cp-integration subscription.

D. The ibm-common-services namespace

The IBM Common Services namespace is used for foundational services, but it is not required for defining an operator subscription in a new namespace.
