How to expose ingress path of K8s as a target in prometheus

[bmv126]

Bug Report

What did you do?
I have a K8s cluster (1.9 version) on which, I have a service running. I have enabled the jmx and have used the jmx exported to get the metrics in prometheus format.
For the user to access, I have created an ingress path for the jmx metrics, below is the k8s ingress resourse:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: jmx-ingress
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /
kubernetes.io/ingress.class: nginx
spec:
rules:

• http:
  paths:
  • path: /MyMetrics/
    backend:
    serviceName: service-jmx
    servicePort: 49115

Now using https://IP ADDRESS:PORT/MyMetrics/ , I am able to see the metrics.

But If set the target in prometheus.yml as below:
scrape_configs:
- job_name: prometheus
static_configs:
- targets:
- 10.194.11.35:80/MyMetrics/

I get below error:
Error loading config" err="couldn't load configuration (--config.file=/etc/config/prometheus.yml): "10.194.11.35:80/MyMetrics/" is not a valid hostname"

What did you expect to see?
I expect to see the metrics getting scraped on the prometheus server.

What did you see instead? Under which circumstances?
Prometheus server pod does not come up as it failing with the error.
level=error ts=2018-06-05T09:18:29.782548012Z caller=main.go:356 msg="Error loading config" err="couldn't load configuration (--config.file=/etc/config/prometheus.yml): "10.194.11.35:80/MyMetrics/" is not a valid hostname"

Environment

This doesn't look like a bug so would need to ask in the users group 👍

I would recommend looking through the official docs and examples as well as searching in the google groups as there is a good chance that you will find the answer immediately.

Feel free to reopen if you are 100% convinced that is a bug in Prometheus.
