[ Issue ]:

From https://github.com/edgexfoundry/device-sdk-c/tree/b5fd43aa6b4e8069e65248caa2e7d6db03f961ef/src/c/examples/random

I have cloned it to my local machine and built it, build was sucessful.

I'm running hybrid mode with the device-random service, I executed ./device-random -cp=consul.http://localhost:8500 -r -o but encountered the following error:

Please note I'm trying to run it in hybrid mode with my docker-compose.yml file,

I Have modified /etc/hosts and added 127.0.0.1 edgex-core-metadata to it & now it works, but I don't think this is the proper solution for this issue.

# GET command to edgex-core-metadata returns 200 in response
