BoxSize Service

(Docker - Makefile - golang)

BoxSize is a golang micro-service to compute the volume contains inside a box.

It accepts tree integers as parameters : height, width, length.

Then the service returns two strings with two informations : The box size in cm³ and the corresponding box capacity in liters.

If 42 is a number somewhere, we raise an error because it's a special number.

Installation

You can build and run the service inside a Docker. The makefile has a docker-build and a docker-run commands.

$> make docker-build
$> make docker-run
+ exec app
BoxSize Server will run on port 3000

If you prefer avoid docker, feel free to run :

make run
