how to automate add the new Node Exporters to the targets array of prometheus.yml

[bdonth]

i have basic prometheus.yml file in my environment i.e ..

###
 apiVersion: v1
 kind: ConfigMap
 metadata:
   creationTimestamp: null
   name: prometheus-core
 data:
   prometheus.yml: |
     global:
       scrape_interval: 10s
       scrape_timeout: 10s
       evaluation_interval: 10s
 
     rule_files:
       - '/etc/prometheus-rules/*.rules'
 
     scrape_configs:
        # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
       - job_name: 'prometheus'
 
         # Override the global default and scrape targets from this job every 5 seconds.
         scrape_interval: 5s
 
         # metrics_path defaults to '/metrics'
         # scheme defaults to 'http'.
 
         static_configs:
           - targets: ['localhost:9090'] 

Now if i get any new Nodes in my environment, my prometheus.yml file should get automatically updated my targets section like below i.e.

###
  apiVersion: v1
  kind: ConfigMap
  metadata:
    creationTimestamp: null
    name: prometheus-core
  data:
    prometheus.yml: |
      global:
        scrape_interval: 10s
        scrape_timeout: 10s
        evaluation_interval: 10s
  
      rule_files:
        - '/etc/prometheus-rules/*.rules'
  
      scrape_configs:
         # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
        - job_name: 'prometheus'
  
          # Override the global default and scrape targets from this job every 5 seconds.
          scrape_interval: 5s
  
          # metrics_path defaults to '/metrics'
          # scheme defaults to 'http'.
  
          static_configs:
            - targets: ['localhost:9090','12.10.17.6:9100','12.10.17.19:9100'] 

Can any one suggest how i achieve this ?
