Floki is a simple micro-service that aggregates [Kafka](https://kafka.apache.org/) logs, sorts them and pushes them to [Grafana Loki](https://github.com/grafana/loki).

## About The Project

![Floki Diagram](images/floki.png)

[Loki](https://github.com/grafana/loki) has [Promtail](https://github.com/grafana/loki/tree/master/pkg/promtail) which is an agent that installs itself in every k8s cluster nodes and collects the pods logs and sends them to Loki. Since we use the [ELK Stack](https://www.elastic.co/pt/products/) in our infrastructure, each k8s node has the [Filebeat](https://www.elastic.co/pt/products/beats/filebeat) agent running for log collection, so by using Promtail, we are 

effectively duplicating the functionality. To avoid this, we have created Floki, which subscribes to our Kafka logging topics, orders the logs and sends them to Loki.

## Getting Started

To run Floki, you need to have the [ELK Stack](https://www.elastic.co/pt/what-is/elk-stack) or other distributed logging system compatible with Kafka and also Loki installed in your infrastructure.

### Usage

```sh

docker run nosinovacao/floki \

   -lokiurl="http:///api/prom/push" \

   -brokerList="" \

   -topicPattern="^logging-*"

```
