Epic Goal

• Support Google Cloud's WIF (Workload Identity Federation) for OADP.

• Why is this important?

• [Upstream Design| None
• Downstream Design

Scenarios

1. GCP WIF authentication + normal regression and function test.
2. Ensure normal GCP auth works + normal regression and function test
3. Special attention to backups w/ imagestream enabled.

Acceptance Criteria

• CI - MUST be running successfully with tests automated
• Release Technical Enablement - Provide necessary release enablement details and documents.

Dependencies (internal and external)

1. Velero
2. GCP cloud
3. GCP account that can edit roles

1. TBD
