# Node Exporter Secure

This is a custom API written with FastAPI Python framework that forwards [Prometheus Node-Exporter](https://github.com/prometheus/node_exporter) metrics data over secured endpoint with Bearer Auth

## Installation

### Docker-Compose

  Fully complete `docker-compose.yml` ready to deploy, you only need to update `API_BEARER_TOKEN` env variable

```yaml

services:

  node-exporter:

      image: quay.io/prometheus/node-exporter:latest

      container_name: node-exporter

      command:

        - '--path.rootfs=/host'

      pid: host

      restart: unless-stopped

      volumes:

        - /:/host:ro,rslave
