# node-exporter
Containerized, multiarch version of node-exporter, used for [Prometheus](https://prometheus.io/) monitoring. Multi-stage build is used to build from official [node-exporter source code](https://github.com/prometheus/node_exporter). Designed to be usable within x86-64, arm64, armv6, and armv7 based Docker Swarm clusters. Added support for correct reporting of the underlying node hostname
## Automated Build and Deploy
This repository utilizes GitHub Actions to automatically build and deploy multiarch images to DockerHub when a new tag is pushed.
## Build and Deploy multiarch image locally
Setup local environment to support Docker experimental feature for building multi architecture images, [buildx](https://docs.docker.com/buildx/working-with-buildx/). Follow instructions [here](https://engineering.docker.com/2019/04/multi-arch-images/)
Clone repo:
```bash
$ git clone https://github.com/jmb12686/node-exporter
$ cd node-exporter
```
Build multiarch image:
```bash
$ docker buildx build --platform linux/amd64,linux/arm64,linux/arm/v6 -t jmb12686/node-exporter:latest --push .
```
## Usage
Use in docker-compose swarm stack similar to base image for `prom/node-exporter`, but added:
* `NODE_ID` as environment variable
* mount `/etc/hostname` of underlying host to `/etc/nodename` in the container.
* Entrypoint script within container will use `/etc/nodename` and `NODE_ID` to create custom data attributes and put config in `/etc/node-exporter`.
* `node-name` and `node-id` attributes are exposed in node-exporter
