Kubernetes Services DNS

  • Starting with 1.11, CoreDNS is provided as an internal DNS
  • When using hostnames(e.g. curl {hostname}) it works only when the services are in the same NameSpace
  • If not, FQDN(Fully Qualified Domain Name) is required (e.g. curl {hostname}.{namespace}.svc.cluster.local)
