Auto discover subscription by using metadata service #65

Closed ebuildy closed 8 months ago

ebuildy commented 9 months ago

Running azure-metrics exporter in a kubernetes pod, in a AKS cluster.

The exporter should find location environment subscriptionId parameters automatically from metadata service ( http://169.254.169.254/metadata/instance?api-version=2021-02-01).

As a workaround, I have added a nginx proxy sidecar in order to "inject" theses parameters, but will be much better if the exporter can do it.

Metadata API is often forbidden as this could be used to access VM identities. aad-pod-identity service used a iptables redirection and a proxy to filter it but still can be dangerous to open this endpoint for services.

not sure if there would be a better way to get some kind of auto configuration. some people are scraping multiple locations/subscriptions with one service.

defining defaults via env vars would be an option.
