# blackbox-exporter-cloudfunction

This is a [blackbox_exporter](https://github.com/prometheus/blackbox_exporter) that runs on GCP Cloud Functions, insipired by [blackbox-exporter-lambda](https://github.com/discordianfish/blackbox-exporter-lambda).

It can be configured like a normal blackbox_exporter, an example config can be found [here](https://github.com/prometheus/blackbox_exporter/blob/v0.17.0/example.yml).

## 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.

```terraform

module "blackbox-exporter-cloudrun" {

  source      = "github.com/ninech/blackbox-exporter-cloudfunction//terraform?ref=v0.1.2"

  project     = "some-project-id"

  region      = "europe-west6"

  bucket_name = "my-cloudfunctions"

  config      = file("config.yml")

}

```

## Resources

To get consistent performance it is recommended to at set `var.available_memory_mb` to at least `256`. The function does not need that much memory but this will also give it more [CPU power](https://cloud.google.com/functions/pricing#compute_time). The costs should pretty much equalize or be even less as the function will finish way faster than with just 128MB/200Mhz.

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

## Testing the function

```bash

curl "https://?target=https://example.org"

```
