I am trying to implement Kubernetes Network policy in my application on the basis of domain name to control the Egress and Ingress calls to the pod. I found DNSSelector but it seems from there last comment that this feature is not implemented in Kubernetes.
I explored calico also, but in calico this feature comes under calico-enterprise hence it is paid. Can someone let me know if any other way out there to achieve this or maybe DNSSelector is being implemented now in Kubernetes?
This is a community wiki answer. Feel free to expand it.
Unfortunately, the DNSSelector is not yet implemented in Kubernetes (nor being implemented).
Calico Enterprise supports such functionality if you wish to pay for it.
