Conversation
📝 WalkthroughWalkthroughThe ArgoCD Agent Principal Service API and CRD now support annotations. Reconciliation applies and updates configured annotations while preserving unrelated existing annotations. Deep-copy logic and unit, conversion, and end-to-end tests cover the change.

Clone Annotations in ConvertAlphaToBetaPrincipalServer.
v1beta1.ArgoCDAgentPrincipalServiceSpec(src.Service) copies the Annotations map header and shares its backing storage. A mutation to either map can change the other object. Clone Annotations and add a mutation test.

ArgoCD.ConvertToreachesConvertAlphaToBetaPrincipalServer, which convertssrc.Serviceby value. The newAnnotationsmap is therefore shared between the alpha and beta objects, so mutating either object changes the other.

What type of PR is this?
/kind enhancement
What does this PR do / why we need it:
Add
spec.argoCDAgent.principal.server.service.annotationsso users can set MetalLB (or other load-balancer) annotations on the Principal Service from the ArgoCD CR. Without this field, the operator cannot apply those annotations and will not preserve user-specified values across reconcile.CR annotations are merged onto
<argocd>-agent-principalonly. Other principal services (metrics, healthz, redisproxy, resource-proxy) are unchanged, and existing Service annotations (for example those added by MetalLB) are preserved.Have you updated the necessary documentation?
API field comments were added on
ArgoCDAgentPrincipalServiceSpecin v1alpha1 and v1beta1 (and the CRD). Generated API docs can be refreshed in a follow-up if that is done separately.Which issue(s) this PR fixes:
