Setting the IP for Blackbox_exporter

[Romenyrr]

Greetings,

I'm setting up an http probe on an AWS EKS cluster, and I'm curious if there's a better way to set the __address__ label rather than hardcoding a POD IP to the prometheus yaml. As per the instructions found here, I started here as a baseline and that worked fine

- job_name: "blackbox"

    honor_labels: true

    kubernetes_sd_configs:

      - role: pod

    relabel_configs:

      - source_labels: [__meta_kubernetes_pod_container_name]

        regex: 'blackbox-exporter'

        action: keep

- job_name: 'blackbox-healthcheck'

    metrics_path: /probe

    params:

      module: 

      - http_2xx

    static_configs:

      - targets:

        - google.com

        - facebook.com

    relabel_configs:

      - source_labels: [__address__]

        target_label: __param_target

      - source_labels: [__param_target]

        target_label: instance

      - target_label: __address__

        replacement: 10.0.2.43:9115  # The blackbox exporter's real hostname:port.

I attempted to do a dynamic replacement of the IP to point to the pod_ip that hosts the pod, but that didn't work and it was just probing itself :(. Here's what that attempt looked like. Is there a cleaner way to pass in the pod IP from one job to another? Should I be taking a different approach? Any recommendations would be greatly appreciated
