blackbox-exporter-cloudfunction

This is a blackbox_exporter that runs on GCP Cloud Functions, insipired by blackbox-exporter-lambda.

It can be configured like a normal blackbox_exporter, an example config can be found here.

Deploying

The terraform directory provides a ready to be used Terraform module to easily deploy this function. Just put your blackbox exporter config next to your Terraform config and reference it with the file function.

module "blackbox-exporter-cloudrun" {
  source      = "github.com/ninech/blackbox-exporter-cloudfunction//terraform?ref=v0.1.0"
  project     = "some-project-id"
  region      = "europe-west6"
  bucket_name = "my-cloudfunctions"
  config      = file("config.yml")
}

This does not require any authentication but is only available within the VPC using the ALLOW_INTERNAL_ONLY ingress setting.

Testing the function

curl "https://<url_from_output>?target=https://example.org"

func Handler(w http.ResponseWriter, r *http.Request)

Handler is a http.Handler which will be called by the GCP Cloud Function on every request. It has been adapted from the original blackbox_exporter probeHandler: https://github.com/prometheus/blackbox_exporter/blob/63678419a6a274ac6d43d3d4088cad2a1d06371f/main.go#L70
