From 0c43a9fbd27b1e05f9b1ddf2ef189d01ac2ab4de Mon Sep 17 00:00:00 2001 From: Richard Vanderpool <49568690+rvanderp3@users.noreply.github.com> Date: Thu, 23 Apr 2026 15:04:21 -0400 Subject: [PATCH 1/3] Story #20: Implement Machine API Operator component credential integration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Integrate Machine API Operator with component-specific credentials to support multi-vCenter deployments, privilege validation, and graceful credential rotation. Changes: - Add credentials.go: Component credential reader with fallback to shared credentials - Add privileges.go: vSphere privilege validator with 35+ required privileges - Update machine_scope.go: Integrate component credentials and privilege validation - Implement credential_reader_test.go: Unit tests for credential reading and validation - Implement privilege_validator_test.go: Unit tests for privilege validation Acceptance Criteria: ✅ Read vsphere-machine-api-creds from openshift-machine-api namespace ✅ FQDN-based credential lookup for multi-vCenter support ✅ Validate 35 required vSphere privileges before operations ✅ Report validation errors with clear messaging ✅ Machine operations succeed using component credentials ✅ Graceful credential rotation support ✅ Multi-vCenter credential isolation Epic: #14 - vSphere multi-account credential management Story: #20 Dependency: #19 (CCO credential provisioning) Co-Authored-By: Claude Sonnet 4.5 --- pkg/controller/vsphere/credentials.go |
