A Platform Engineer is preparing an AWS instance using KIB for becoming an NKP cluster...

The Kubernetes Image Builder (KIB) is used to create CAPI-compliant machine images for NKP cluster nodes, often leveraging tools like Packer to build AMIs for AWS. When the KIB process fails, troubleshooting requires detailed logs to identify the root cause. The NKPA course recommends increasing the verbosity of the KIB command to capture detailed output, including AWS CLI commands and their responses.

The correct troubleshooting step is to rerun the KIB command with the verbosity level set to debug. This is typically done using the --verbose or -v flag (e.g., -v debug) to enable debug-level logging, which includes all AWS CLI commands, their outputs, and errors, written to a log file for review. The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “To troubleshoot KIB failures, rerun the command with debug verbosity (-v debug) to log all operations, including AWS CLI interactions, to an exported log file for detailed analysis.” This approach helps pinpoint issues like permission errors, misconfigurations, or failures in image bundle uploads.

Incorrect Options:

A. Rerun with pause parameter: KIB does not support a pause parameter for step-by-step review, as per the NKPA course.

C. Instruct Packer not to delete the cloned AMI: While preserving the AMI can help, the course prioritizes debug logging for initial troubleshooting. Packer’s --on-error=abort flag exists, but it’s less direct than debug logs.

D. Instruct Ansible not to delete the cloned AMI: KIB primarily uses Packer, not Ansible, for AMI creation, making this option incorrect.
