Istio add-on to be enhanced for supporting Initialisers, this includes the following steps:

  1. Update the master-config.yaml to add Initializers plugin

admissionConfig:
  pluginConfig:
    GenericAdmissionWebhook:
      configuration:
        apiVersion: v1
        disable: false
        kind: DefaultAdmissionConfig
      location: ""
    Initializers:
      configuration:
        apiVersion: v1
        disable: false
        kind: DefaultAdmissionConfig
      location: ""
