After upgrading from 1.3.x to 1.4.x I am experiencing 404s unless I specify the host header of the services DNS, for example:
curl -I something.example.com will return a 404 curl -I something.example.com -H “something.ns.svc.cluster.local” will work.
I should mention that we’re using CoreDNS to rewrite hostnames to services.
I read the upgrade notes and I don’t see anything there that would break this.
Thanks in advance!
