I want to monitor some endpoints using Prometheus black box-exporter. For that I am building a new custom "black box-exporter" image using the Docker Hub image as base under my docker file {FROM docker.io/prom/blackbox-exporter:latest} So that I can add some required certs etc. with the image.

I am successfully able to deploy the image to k8 cluster and also can view my target under "Prometheus -> status -> targets". However the target endpoint is some ip address like "target="11.11.111.111:9115" not what i defined under service monitoring yml ";.

Can someone please assist me to fix the servicemonitoring.yaml ?

Note : wget -qO- ":9115/probe?target=;module=http_2xx&debug=true" probes fine when tested from k8 blackbox pod.

Thanks in advance !
