Proposal

I am using Prometheus in kubernates, and recently enabled basic Auth with version 2.28. But it turn out Prometheus also enables security on health endpoints. Their is no way to safely provide credentials for liveness and readiness probe. Following works but not really the safest option. I think we should have a option to disable security on these endpoints.

livenessProbe:
      httpGet:
        path: /-/healthy
        port: 9090
        httpHeaders:
        - name: Authorization
          value: Basic dXNlcjpwYXNz

This could be a generic functionality to disable authentication on certain endpoints. Will need an additional option in web-config.yml and corresponding check in users.go.

Should this issue be moved to exporter toolkit repo?

Thank you, I think we could maybe have an excludeEndpoint configuration option in the web.yml, but I feel like we should discuss this more broadly on the developers mailing list, because e.g. the pushgateway might want to go one step further and even have per-path authentication.

Would be very helpful if I can disable security for certain endpoints like "/-/ready" or "/-/healthy" - specially when running under K8S. Is there already an ongoing discussion on the dev mail list? I was not able to find it ...
