ServiceExportReconciler keep re registering instances in aws cloudmap

Hi,

We are running v0.3.1 of aws-cloud-map-mcs-controller to register services to aws cloudmap. we have another application looks up cloudmap for service discovery. we have a requirement to populate some custom attributes for cloud map instances.

is there a way to define custom attributes in ServiceExport definition of kubernates object?. currently its defined like this.

kind: ServiceExport
apiVersion: multicluster.x-k8s.io/v1alpha1
metadata:
namespace: namespace1
name: service-name

currently we are using a lambda trigger in aws to populate these custom attributes. this is causing an issue with ServiceExportReconciler , its keep re registering instances in aws cloudmap as endpoint/instance definition is different in aws cloudmap to what controller desires . is there a way to stop this re register from happening?.

Thank you.

Start by reading the ServiceExportReconciler and the ServiceExport definition shown in the issue, then trace how endpoint and instance definitions are registered in AWS Cloud Map. Determine whether custom attributes can be represented in the ServiceExport or preserved during reconciliation. Done means the requested attributes and re-registration behavior have a documented, tested resolution.
