Calculation Service

This service is meant to calculate the cost of a trip based on the ORIGIN and DESTINATION. We use Gorilla Mux as a framework for the REST API.

The service currently depends on the gmaps-adapter.

Set Up

Go Environment

Please read carefully through the Go documentation on how to set up the main environment. After downloading the package, a site should pop up giving you further installation/setup instructions.

To get the calculation service project (make sure you've set up the Go environment) simply cd into your GOPATH and run this command: go get github.com/AITestingOrg/calculation-service.

• After completing these steps, go should automatically install the necessary dependencies needed to begin developing.

If set up following the Go documentation, the calculation-service folder/repository should now be found under go → src → github.com → AITestingOrg.

Running

To run locally:

• Have the gmaps adapter repository cloned. Follow the instructions within the README to initiate it using the terminal. Make sure that it's listening and serving on port 8080.
• Build any changes you may have made (or if you haven't built at all) with the command go build within the terminal under the calculation-service folder.
• Begin the calculation service with the command ./calculation-service, it should log that the service is running.
• When running locally, Eureka will not be initialized.

To run using docker-compose: (be sure to have Docker installed)

• Be sure to run docker-compose pull to make sure you have the latest images pulled.
• Run docker-compose up --build within the calculation-service folder.
• Both services gmaps and calculation should be initiated and also registered by Eureka.
