In IBM Cloud Pak for Integration (CP4I) v2021.2, the CA (Certificate Authority) domain specified for the cluster is typically stored in the config.yaml file. This file contains cluster-wide configuration settings, including TLS certificates, security settings, and domain details used for CA and authentication.
config.yaml is a standard Kubernetes and OpenShift configuration file format that stores cluster-wide settings, including CA domain and security configurations.
This file defines certificate authority (CA) details, domain names, authentication settings, and cluster networking information.
It is commonly used when configuring IBM Cloud Pak foundational services and handling TLS/SSL certificates for secure communication between CP4I components.
Why Option C (config.yaml) is Correct:
A. ca.config → Incorrect
There is no standard ca.config file in IBM Cloud Pak for Integration or OpenShift for defining the CA domain.
CA-related configurations are stored in certificates and security configuration files, usually inside config.yaml.
B. config.json → Incorrect
JSON format (config.json) is not used for cluster-wide configurations in CP4I or OpenShift.
Configuration files in OpenShift and Kubernetes are typically in YAML (.yaml) format.
D. domain.config → Incorrect
domain.config is not a standard configuration file for IBM Cloud Pak for Integration.
Domain settings are managed in config.yaml and other Kubernetes secret configurations.
