Well due to the fact that OpenShift 4 was completely redesigned is the dnsmasq not anymore part of OpenShift 4. How the DNS Operator works is described in the README.md https://github.com/openshift/cluster-dns-operator You can see the Corefile config here. https://github.com/openshift/cluster-dns-operator/blob/master/pkg/operator/controller/controller_dns_configmap.go Here is documented how the DNS Operator can be configured. https://docs.okd.io/latest/networking/dns-operator.html There is a cache plugin for coredns but it's not yet configurable in OpenShift. https://coredns.io/plugins/cache/ Maybe you can raise a RFC https://github.com/openshift/cluster-dns-operator/issues to be able to configure the cache feature in OpenShift.
