## Installing CoreDNS with kubeadm
|
|
|
|
In Kubernetes 1.9, [CoreDNS](https://coredns.io) is available as an alpha feature and
|
|
may be installed by setting the `CoreDNS` feature gate to `true` during `kubeadm init`:
|
|
|
|
```
|
|
kubeadm init --feature-gates=CoreDNS=true
|
|
```
|
|
|
|
This installs CoreDNS instead of kube-dns.

|
|
You can configure [CoreDNS](https://coredns.io) to support many more use cases than
|
|
kube-dns by modifying the `Corefile`. For more information, see the
|
|
[CoreDNS site](https://coredns.io/2017/05/08/custom-dns-entries-for-kubernetes/).
