kube-summary-exporter

Exports prometheus metrics for the Kubernetes Summary API.

This exists because of: https://github.com/google/cadvisor/issues/2785

Docker / Podman image available: quay.io/utilitywarehouse/kube-summary-exporter

All available tags: https://quay.io/repository/utilitywarehouse/kube-summary-exporter?tab=tags

Run locally

To run exporter locally run go run ./...

This will run server on default port 9779

Visiting http://localhost:9779/node/example-node will return metrics for the node 'example-node'. App will look for example-node in the current-context cluster set in kube config.

Here's an example scrape config.
