Support for Google Managed Prometheus on Prometheus Scaler

[nettoclaudio]

Proposal

The Prometheus scaler should have the capability to directly retrieve metrics from Google Managed Prometheus. This entails supporting OAuth2 token exchange for authentication purposes, allowing access to Google's Monitoring API, which implements the Prometheus API.

Use-Case

Integrating Google's authentication directly into the Prometheus scaler would eliminate the need for a Prometheus proxy, such as Google's Prometheus fork (read more), solely for handling authentication with the Google Monitoring API. This feature streamlines the authentication process and removes unnecessary deployments in the cluster.

Is this a feature you are interested in implementing yourself?

Yes
