By default, a client Pod’s DNS search list will include the Pod’s own namespace and the cluster’s default domain. This is best illustrated by example: Assume a Service named “ my-service ” in the Kubernetes namespace “ dev ” . A Pod running in namespace “ dev ” can look up this service by simply doing a DNS query for “ my-service ” . A Pod running in namespace can look up this service by doing a DNS query for my-service.dev . Kubernetes offers a cluster addon for DNS service discovery, which most environments enable by default. “SkyDNS” seems to be the standard DNS server of choice, since it was designed to work on top of etcd. The “ kube-dns” addon is composed of a kubernetes service which, like all services, is allocated an arbitrary VIP within the preconfigured subnet (this is the IP that every other serv...
