Resolve machine cluster-ID tags only from the matching openshift- category. This avoids attaching an unrelated tag when vCenter contains duplicate tag names across categories.

Add a category-aware tag lookup to CachingTagsManager. It caches name lookups by category ID and tag name, validates cached tag identity, and supports tag IDs while enforcing category membership.

Cover duplicate-name reconciliation and verify scoped cache hits avoid additional vCenter requests.

Summary by CodeRabbit

  • Bug Fixes
    • vSphere machine reconciliation now selects a tag from the category associated with the cluster ID when the tag name matches the cluster ID. This prevents a same-named tag from another category from being attached by mistake and ensures machines receive the intended cluster-specific tag when duplicate tag names exist across categories.
    • Repeated category-specific tag lookups are cached, reducing requests to vCenter.

Resolve machine cluster-ID tags only from the matching openshift-<cluster-id> category. This avoids attaching an unrelated tag when vCenter contains duplicate tag names across categories.

Add a category-aware tag lookup to CachingTagsManager. It caches name lookups by category ID and tag name, validates cached tag identity, and supports tag IDs while enforcing category membership.

Walkthrough

Tag reconciliation now resolves a cluster-ID-named tag within the openshift-<clusterID> category. The caching tag manager adds category-scoped lookup by tag name and validates tag IDs against the requested category. Tests cover category validation, duplicate tag names, and cached lookup reuse.

Changes

vSphere tag lookup

Layer / File(s) Summary
Category-scoped lookup and cache
pkg/controller/vsphere/session/tag_ids_caching_client.go, pkg/controller/vsphere/session/test_ids_caching_client_test.go
CachingTagsManager resolves tags within a category and caches results by category and tag name. Tests check tag-ID category validation and cache reuse across repeated and cross-category lookups.
Cluster-ID tag reconciliation
pkg/controller/vsphere/reconciler.go, pkg/controller/vsphere/reconciler_test.go
Reconciliation looks up a tag named for the cluster ID in the openshift-<clusterID> category. A test checks that reconciliation attaches the tag from that category.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~12 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to 6987c

The change is mergeable with bounded risk, but the tag-ID test should use an existing second category so it protects the intended behavior.

Remove the ordering-dependent unqualified lookup assertion.

govmomi v0.53.0 returns the first same-name tag from a list that the simulator builds by iterating a map. Go does not guarantee that the unrelated tag comes first. This assertion can fail even when reconcileTags attaches the correct tag. Remove the precondition and keep the assertions on the attached tag IDs. (raw.githubusercontent.com)

Keep GetTagForCategory focused on the name-and-category lookup used for cluster IDs. Remove the unused empty-category fallback and tag-ID handling.
Restore GetTagForCategory support for tag IDs and verify that ID-based lookups only return tags belonging to the requested category. Keep the category-scoped name cache behavior unchanged.

Create other-category before testing tag-ID rejection.

GetTagForCategory resolves the category before it checks the tag ID. Because other-category is not created, the assertion can pass on a missing-category error without checking CategoryID. Create the category first and check the creation error. The existing scoped-name test does not cover a tag ID from another existing category.

Create `other-category` before the `GetTagForCategory` assertion and check the
category-creation error, ensuring the call reaches tag-ID validation against an
existing category rather than passing due to a missing category.
