I’ve been trying to figure this out as well.
I haven’t yet found a way of publishing to kube-dns the pod IP of the
running service.
I.e.:
kamailio.whatever.local on ip 10.0.0.1
Rtpengine.whatever.local on ip 10.0.0.2
Appserver.whatever.local on 10.0.0.3
Assuming those are pod ips. Using services doesn’t work since the dns name
will resolve to a k8s service ip and no the actual pod running the service.
Assigning IPs hardcoded doesn’t work either since it might change if the
docker changes pod. I can have multiple modes on which a service can run,
but only one service (kamailio, rtpengine, appserver, etc) will run on a
given pod.

Hi

You can use the kubedns/CoreDNS of the kubernetes cluster to resolve
Internal DNS records of the pods.To assign DNS records for each POD you
have to deploy a service and set the ClusterIP: none. and the dns record
will be something like kamailio.kamalio-service.platform.svc.cluster.local
which is the podname.servicename.namespace.svc.cluster.local
In the resolve.conf you will put the kubeDNS/CoreDNS IP as the
nameserver. You can set this in the kubernetes manifest file
dnsPolicy: "None"
dnsConfig:
nameservers:
- 10.34.0.1 (
kubeDNS/CoreDNS )

I am not k8s developer.
So cannot provide detailed instructions. Just my point of view.
You can look

-- Hi,
It would be helpful if you could elaborate what has to be done for
kubernetes pods when you mention sip ingress
Thanks,

Lot of issues with static IP in Kubernetes.
Looks as need deploy "sip ingress" like "HTTP/HTTPS ingress" and
then
route calls to pods.
