Using Docker

You can deploy this exporter using the Docker image.

For example:

docker pull c4po/harbor-exporter

docker run -d -p 9107:9107 -e HARBOR_USERNAME=admin -e HARBOR_PASSWORD=password c4po/harbor-exporter --harbor.server=https://harbor.dev

Run in Kubernetes

if you deploy Harbor to Kubernetes using the helm chart goharbor/harbor-helm, you can use this file kubernetes/harbor-exporter.yaml to deploy the harbor-exporter with secretKeyRef

Using Grafana

You can load this json file grafana/harbor-overview.json to Grafana instance to have the dashboard.
