Challenge: Exporter for Prometheus
==================================
This is an prometheus metrics exporter for the soundcloud challenge. 

Requirements
------------

* Docker, of course ;-)
* Working go 1.8 (older should work as well)

Build
--------------------
Build binary `exporter`:
```bash
make
```

Build docker image with tag `challenge/exporter`:
```bash
make docker
```

Run
---
Start locally in docker: 

```bash
docker run -d -p 8080:8080 --name challenge beorn7/syseng-challenge
docker run -d -p 8081:8080 --link challenge --name challenge_exporter challenge/exporter --endpoint http://challenge:8080/stats

docker stop challenge_exporter
docker rm challenge_exporter
docker stop challenge
docker rm challenge
```
or with docker-compose
```bash
docker-compose up
```

Metrics should now be availabe on `http://localhost:8081/metrics`
