driver's Introduction

Driver

The services composing this application are found in subdirectories:

gateway an elixir service, that either forward or transform requests to be processed synchronously or asynchronously.
location a go service, that consumes location update events and store them.
zombie a go service, that allows to check if a driver matches the zombie predicate or not.

Each service has it's own readme with instructions for getting them up and ruuning

Assumptions

This project has been built on OSX and the instructions assume a unix environment with some mac specific references.

Prerequisites

You will need to have the following tools installed to run locally:

Docker (I've used Docker for Mac)
Docker Compose

Development

As some of these services are go packages, you'll need to have set your $GOPATH this repo cloned to $GOPATH/src/driver.

Please ensure you have the following language versions installed:

$ go version
go version go1.9.4 darwin/amd64

$ elixir -v
Erlang/OTP 20 [erts-9.1] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:10] [hipe] [kernel-poll:false]

Elixir 1.6.1 (compiled with OTP 19)

To get the compose cluster up an running use:

$ ./start.sh
...

Too bring the cluster down use:

$ ./stop.sh
...

To see the list of running containers user:

$ docker-compose ps
...

To see the container logs use:

$ docker-compose logs
...

The gateway service will be available locally via: localhost:3000 The location service will be available locally via: localhost:3001 The zombie service will be available locally via: localhost:3002 The NSQ admin page will be available locally via: localhost:4171
