Can I use Kubernetes dns service to whitelist the domains for my pods? I want to restrict the outgoing (egress) calls using Kubernetes dns service. if I can achieve this, can someone let me know the steps required to implement this.
Note: I see in my default pods that coredns pod is already present with image: rancher/coredns-coredns:1.8.3. I understand that it comes default with k3s.
PS: I have already explored calico and other network policy but they are not fulfilling my requirement.
