Problem (FLPATH-3145)

The cost-onprem helm chart uses the 'lookup' command in templates, which breaks oc-mirror for disconnected customers. The error occurs when oc-mirror tries to template the chart:

execution error at (cost-onprem/templates/infrastructure/storage/job-minio-buckets.yaml:3:24): ODF (OpenShift Data Foundation) not detected. This chart requires ODF with NooBaa for S3 storage.

The 'lookup' command requires an active kubernetes cluster connection, making the chart incompatible with oc-mirror which needs to template charts offline.

Root Cause

The helm 'lookup' function is used to detect ODF/NooBaa presence, but this approach:
- Requires cluster connectivity during templating
- Breaks oc-mirror functionality for disconnected environments
- Prevents chart packaging and mirroring

Solution

Replace 'lookup' commands with alternative approaches that don't require cluster connectivity:
- Use values.yaml configuration options instead of runtime detection
- Move cluster validations to post-install hooks or init containers
- Provide clear documentation for required dependencies

Acceptance Criteria

• [ ] Identify all uses of 'lookup' command in chart templates
• [ ] Replace lookup-based ODF detection with values.yaml configuration
• [ ] Update templates to use conditional logic based on values
• [ ] Create post-install validation hooks if needed for runtime checks
• [ ] Update values.yaml with new configuration options
• [ ] Test chart templating works without cluster connectivity
• [ ] Verify oc-mirror can successfully template and mirror the chart
• [ ] Update documentation for new configuration approach

Definition of Done

• No 'lookup' commands remain in helm templates
• Chart can be templated offline without cluster connectivity
• oc-mirror successfully processes the chart
• Functionality is preserved through alternative configuration
