Is there a way to add any rule in default section

[diwakar-s-maurya]

I want to send a unique string in header to backend for every request. The below configuration is works fine

apiVersion: voyager.appscode.com/v1beta1
kind: Ingress
metadata:
  name: test-ingress
  namespace: default
spec:
  frontendRules:
  - port: 80  # Applies all the rule in frontend section for port 80
    rules:
    - unique-id-header X-Unique-ID
    - unique-id-format %{+X}o\ %ci:%cp_%fi:%fp_%Ts_%rt:%pid
    - log-format %ci:%cp\ [%t]\ %ft\ %b/%s\ %Tq/%Tw/%Tc/%Tr/%Tt\ %ST\ %B\ %CC\ %CS\ %tsc\ %ac/%fc/%bc/%sc/%rc\ %sq/%bq\ %hr\ %hs\ %{+Q}r\ %ID
  rules:
  - host: foo.bar.com
    http:
      paths:
      - backend:
          serviceName: echoserver
          servicePort: '8080'

The rules unique-id-header, unique-id-format and log-format will apply only to one particular frontend.
Is there a way to move these rules in default section of haproxy configmap so that they get applied to every other frontend and I don't have to repeat the rules again for other frontends?
This supports only the option config of haproxy.

@diwakar-s-maurya , frontend rules applies any host that is using the corresponding port (eg 80).

This is not possible today via annotations. But you can use custom templates to achieve this. Unless you are exposing many other ports from HAProxy, I would say just use the frontend rules.
