Hi Guys,
I am using headless services for our application and as I deploy more pods
or if a pod crashes and reboots I understand that DNS records will be
updated but is there anything in Kubernetes than push those updated
endpoints to my own process such that my process can do load balancing and
service discovery?
By push I mean something like Ajax push or other way can be Pub-Sub where
my program can subscribe to certain events and starts listening for those
changes?
I am trying to avoid polling. other words I shouldn't write a program that
constantly polls a http endpoint to see if there any changes like code below
while(true) { // This is polling and I am trying to avoid to write this
code
curl http://kubernetes/watch_for_changes_in_the_dns_records
sleep(1 second);
}
push will be more like pseudo code below. pretty much attaching a listener
or something and calling the callback when there are new endpoints.
url = http://kubernetes/watch_for_changes_in_the_dns_records;
url.onUpdate(function() {
update_dns_records
});
