Pull nuclio metrics into prometheus-operator

Question

I am currently trying to pull metrics from nuclio functions to my prometheus operator. But I don't realy understand how I am supposed to do.

So far, I have 2 namespaces :

• monitoring : for my kube-prometheus-stack
• nuclio : for everything related to nuclio (controller, dashboard and functions)

In the nuclio namespace I configured a platform based on the Nuclio Documentation .

My configmap (nuclio-platform-config) :

cronTriggerCreationMode: "kube"
logger: 
  sinks:
    stdout:
      kind: stdout
  system:
  - level : debug
    sink: stdout
  functions:
  - level : debug
    sink: stdout
metrics:
    sinks:
      PromPull:
        kind: prometheusPull
        url: 8090
        attributes:
          jobName: nuclio-pull-job
          instanceName: nuclio-pull-instance
    system:
    - PromPull
    functions:
    - PromPull

As expected, it did not scrape automaticaly my functions' metrics. But I have absolutely no idea what to do next...

If anyone could give me some guidance, I'd be delighted.

PS : I didn't know which config was relevant or not. If you need anything, I will edit my question to add it
