How to: How does DNS work in Kubernetes?
There is a DNS server called skydns which runs in a pod in the cluster, in the `kube-system` namespace. That DNS server reads from etcd and can serve up dns entries for Kubernetes services to all pods. You can reach any service with the name `
.
.svc.cluster.local`. The resolver automatically searches `
.svc.cluster.local` dns so that you should be able to call one service to another in the same namespace with just `
`.
