Les microservices Eureka, BOM et Part sont déployés sur azu ré. Eureka enregistre à la fois les microservices et les détails de microservice dans bom microservice en utilisant "/ service-instances/plm-part-ms", où "plm-part-ms" est le nom de l'application printanière pour microservice. Toute aide serait appréciée !
