In a Kubernetes or OpenShift environment, an Operator's logic runs within a container, which is part of a pod. For an Ansible-based operator, this pod is responsible for executing the Ansible automation. The standard output (stdout) and standard error (stderr) streams from the operator's container are captured as its logs. The primary and standard method for retrieving these logs is by targeting the operator's pod directly using command-line tools like oc logs or kubectl logs . Therefore, the pod is the direct source from which the logs are retrieved.

B. home directory: Operator logs are managed by the container runtime and are not stored in a user's home directory on a cluster node.

C. Ansible directory: This term is ambiguous. It does not refer to the standard location for runtime logs, which are streamed from the container, not typically read from a specific directory.

D. YAML file directory: This directory contains the static, declarative configuration files for deployment, not the dynamic log files generated by the running operator.

1. IBM Cloud Pak for Business Automation Documentation: In the troubleshooting section for operators

the procedure consistently involves identifying the operator pod and then using a command to retrieve its logs. For example: "Get the logs for the operator pods to find information about the error. oc logs -c ". This confirms the pod is the source for log retrieval.

2. Red Hat OpenShift Container Platform Documentation: The official documentation for OpenShift

the platform on which CP4BA runs

specifies that logs for any application

including operators

are accessed at the pod level. "You can view logs for a particular pod... using the oc logs command."

3. Kubernetes Documentation: The fundamental logging architecture of Kubernetes

which underpins OpenShift

states that the basic logging mechanism is to capture the standard output and standard error streams of a container. These logs are made accessible through the kubectl logs command

which targets a specific pod.
