mwthink/prometheus-cryptomarket-exporter repository overview

⁠prometheus-cryptomarket-exporter

This will scrape CoinGecko for cryptocurrency prices and then provide them as Prometheus-style metrics.

The instance will listen for requests on an HTTP server and serve up the metrics.

⁠Deployment

This is intended to be deployed to a Kubernetes cluster with the Prometheus Operator:

kubectl apply -k ./deploy/

You can also run it via Docker:

docker run -p 3000:3000 mwthink/prometheus-cryptomarket-exporter:latest

⁠Docker Images

This project is intended to be run as a Docker image. Images are pushed to the repo docker.io/mwthink/prometheus-cryptomarket-exporter.

There are two tags that should be used:

• latest - Built by the automated system on pushes to the main branch
• multiarch - Built by hand, for multiple architecture types

Both images should be considered stable, the multiarch image might be older.
