[patsch9]

Is your feature request related to a problem? Please describe.
When we create a policies like rewrite policie in a cluster where are multple cic instances for different netscaler instances are present, the policie will be pushed to all netscalers.

Describe the solution you'd like
When i create a policie there have to be a selector for which ingress class i want to push the policie. With this it is possible to make multiple policies for different cic and netscaler instances without to have a lot of unused garbage on the instance where the policie dont be used.
It will be nice when i can select one ore multiple ingress classes where the policie will be pushed to.

@patsch9 We do have the support to provide ingressclass for rewriteCRDs. You can create rewritepolicy matching the ingressclass with the CIC like the following:

apiVersion: citrix.com/v1
kind: rewritepolicy
metadata:
 name: redirectnewhost
spec:
 ingressclass: netscaler-vpx
 responder-policies:
 - servicenames:
     - echoserver
   responder-policy:
      redirect:
        url: '"new-domain-name.com"'
        redirect-status-code: 301
      respond-criteria: 'HTTP.REQ.HOSTNAME.CONTAINS("demo.example.com")'
      comment: 'Redirect to New Domain Name'

Each individual CIC should be deployed with non-conflicting ingressclasses.
If CIC is deployed via yaml file, add the ingressclass in the args. (Refer : Link)

      args:
        - --ingress-classes
          netscaler-vpx

If CIC is deployed via helmcharts, provide the ingressClass in the values.yaml (Refer: Link)

@patsch9 Closing this issue as we already have the support for ingress-class for the CRDs. Please free to reopen if you face any issues.
