The architecture of the complete microservice interaction looks like this:-
The quickstart of application can be started using docker and docker-compose. We can use simple docker-compose command to build the images and start the setup.
# To build the all images of ot-microservices
make build-images
# To start the setup locally
make setupFor further details checkout GETTING_STARTED
