This is a very simple HTTP service for me to play around with Go and Consul. Some of my first Go code so please don't grade it ;)
The build.sh script will pull down a golang container to compile the service. docker-compose will handle creating the service container from the Dockerfile
$ ./build.sh
$ docker-compose up
After you finish building you query it using the names of the service as the path. Feel free to add/change services in the docker-compose.yml. View the examples below to see how exactly it works.
