In a containerized environment managed by Kubernetes or OpenShift, the Operator pattern is used to automate the deployment and lifecycle management of complex applications like IBM Cloud Pak for Business Automation. The Operator is the primary controller that reads the Custom Resource (CR) YAML file and creates all the necessary underlying resources (Pods, Services, ConfigMaps, etc.). When troubleshooting a new deployment, the Operator's log is the first place to check, as it records the entire orchestration process, including any errors encountered while interpreting the CR, pulling images, or creating resources. This log provides the most direct insight into why a deployment might be failing at the infrastructure or orchestration level.

B. Liberty Log: This is an application server log from within the container. It is only useful for troubleshooting application-level issues after the container has successfully started.

C. YAMLlog: This is not a standard log file. YAML files are used for configuration definitions and do not produce their own logs.

D. p8servererror.log: This is a specific error log for the FileNet Content Platform Engine application. It is a secondary, application-specific log and is not relevant for general deployment issues.

1. IBM Cloud Pak for Business Automation Documentation

"Troubleshooting installation and upgrade issues." This official guide frequently directs administrators to check the operator logs as a primary step. It states

"If the operator is stuck in a Pending or Error state

describe the operator pod and check the events and logs." This confirms the operator log is central to diagnosing deployment problems. (IBM Documentation for Cloud Pak for Business Automation 21.0.3

Troubleshooting > Troubleshooting installation and upgrade issues).

2. IBM Cloud Pak for Business Automation Documentation

"Must-gather logs for troubleshooting." The documentation on gathering diagnostic data explicitly lists "Operator logs" as a key component to collect when reporting issues with a deployment

underscoring their importance in the troubleshooting process. (IBM Documentation for Cloud Pak for Business Automation 22.0.2

3. IBM Cloud Pak for Business Automation Documentation

"Troubleshooting the operator." This section provides direct guidance: "Check the logs for the operator pod to see whether there are any obvious errors. Replace with the name of the pod... oc logs -f". This command is a fundamental troubleshooting step for any deployment managed by the operator.
