Custom device-service in edgex foundry. Why would my newly created device-mqtt-service overwrite device-mqtt? I want them to coexist. What requirements are needed?
My mqtt-service port in docker is 59982. My service port is 59983. I ran my service after my docker service ran. Services started after the display are replaced in the edgex foundry.
