Note : You can use my public repository for practice purpose. I have created One application property in git repo with only one property Name=

I already mentioned name of git repo in properties file.

If Your Microservice name and Properties file name Same On git then Directly hit to That name.

Example :spring.cloud.config.uri=http://localhost:8888

server.port=9001

spring.application.name=configclient

On Git repo I have cretaed 2 properties file 1.application and configclient

so whenver configclient microservice need configurauion data it taken from configclient properties
