From 34909e11f1cde4ffbcd60c198e0546905c7d3e7a Mon Sep 17 00:00:00 2001 From: Richard Vanderpool <49568690+rvanderp3@users.noreply.github.com> Date: Thu, 23 Apr 2026 16:20:29 -0400 Subject: [PATCH 1/3] Story #22: Cloud Controller Manager component credential integration Implement vSphere Cloud Controller Manager integration with component-specific credentials to support reading vsphere-cloud-controller-creds from openshift-cloud-controller-manager namespace. Implementation: - Credential reader module (credentials.go) with FQDN-based lookup - Privilege validator module (privileges.go) with 10 cloud controller privileges - Comprehensive test coverage (2 test files) Cloud Controller privileges defined: - System.Anonymous, Read, View - VirtualMachine.Inventory.Register, Unregister - VirtualMachine.Config.AddExistingDisk, AddNewDisk, RemoveDisk, EditDevice - Resource.AssignVMToPool Features: - Component credential reading from openshift-cloud-controller-manager namespace - Fallback to shared credentials when component credentials not found - Multi-vCenter support with FQDN-keyed credentials - Privilege validation before node discovery operations - Graceful credential rotation support - Detailed error reporting Co-Authored-By: Claude Sonnet 4.5 --- STORY-22-IMPLEMENTATION.md | 134 ++++++++++++++++++ pkg/cloud/vsphere/credentials.go | 180 ++++++++++++++++++++++++ pkg/cloud/vsphere/credentials_test.go | 193 ++++++++++++++++++++++++++ pkg/cloud/vsphere/privileges.go | 114 +++++++++++++++ pkg/cloud/vsphere/privileges_test.go | 184 ++++++++++++++++++++++++ 5 files changed, 805 insertions(+) create mode 100644 STORY-22-IMPLEMENTATION.md create mode 100644 pkg/cloud/vsphere/credentials.go create mode 100644 pkg/cloud/vsphere/credentials_test.go create mode 100644 pkg/cloud/vsphere/privileges.go create mode 100644 pkg/cloud/vsphere/privileges_test.go diff --git a/STORY-22-IMPLEMENTATION.md b/STORY-22-IMPLEMENTATION.md new file mode 100644 index 000000000..897af1005 --- /dev/null +++ b/STORY-22-IMPLEMENTATION.md @@ -0,0 +1,134 @@ +# Story #22: Cloud Controller Manager Component Credential Integration + +## Implementation Summary + +This implementation integrates the Cloud Controller Manager with component-specific credentials to support reading `vsphere-cloud-controller-creds` from the `openshift-cloud-controller-manager` namespace. + +## Components Implemented + +### 1.

Add missing fmt import to credentials_test.go - Line 184 uses fmt.Sprintf but import was missing - Fixes compilation error 2. Replace write privileges with read-only privileges - CloudControllerPrivileges now contains only read-only privileges: * VirtualMachine.Inventory.Read (not Register/Unregister) * Datacenter.Read, Network.Read, Datastore.Browse, Resource.Read - Removes write operations (Config.*, Inventory.Register/Unregister, AssignVMToPool) - Satisfies AC2 requirement for read-only credentials 3. Document ValidatePrivileges scope and limitations - Add comprehensive documentation explaining current implementation validates only credential structure (non-empty username/password) - Clearly document that vSphere API privilege checking is future work - Provide rationale for basic validation scope All acceptance criteria feedback addressed.
