Unable to define range of values for ports

My goal is to have multiple ports defined for a service of type LoadBalancer and I do not want to copy paste the same thing over and over again.

I did come to a solution, but sure how I could define the range - I need all values from 50000 to 50999.

In my service, I define the range:

{{- range $service.ports }}
  - name: tport
    protocol: TCP
    port: {{ . }}
  {{- end }}

And in my values file:

ports: 
  - 50000
  - 50001
  - 50999

How could I define the ports or update the service template to do this?

Put the min and max port as two different values on your values.yaml and use the range on your template like this:

{{- range untilStep (.Values.config.min_port|int) (.Values.config.max_port|int) 1 }}
- port: {{ . }}
  targetPort: "tcp-{{ . }}"
  protocol: TCP
  name: "tcp-{{ . }}"
{{ -end }}
