## Deploy DNS
### Get the template file
First of all, download the template dns rc and svc file from
[skydns-rc template](skydns-rc.yaml.in)
[skydns-svc template](skydns-svc.yaml.in)
### Set env
Then you need to set `DNS_REPLICAS` , `DNS_DOMAIN` , `DNS_SERVER_IP` , `KUBE_SERVER` ENV.
```
$ export DNS_REPLICAS=1
$ export DNS_DOMAIN=cluster.local # specify in startup parameter `--cluster-domain` for containerized kubelet
$ export DNS_SERVER_IP=10.0.0.10 # specify in startup parameter `--cluster-dns` for containerized kubelet
$ export KUBE_SERVER=10.10.103.250 # your master server ip, you may change it
```
### Replace the correponding value in the template.
```
$ sed -e "s/{{ pillar\['dns_replicas'\] }}/${DNS_REPLICAS}/g;s/{{ pillar\['dns_domain'\] }}/${DNS_DOMAIN}/g;s/{kube_server_url}/${KUBE_SERVER}/g;" skydns-rc.yaml.in > ./skydns-rc.yaml
$ sed -e "s/{{ pillar\['dns_server'\] }}/${DNS_SERVER_IP}/g" skydns-svc.yaml.in > ./skydns-svc.yaml
```
### Use `kubectl` to create skydns rc and service
```
$ kubectl -s "$KUBE_SERVER:8080" --namespace=kube-system create -f ./skydns-rc.yaml
$ kubectl -s "$KUBE_SERVER:8080" --namespace=kube-system create -f ./skydns-svc.yaml
```
### Test if DNS works
