    34  ## Deploy DNS
    35  
    36  ### Get the template file
    37  
    38  First of all, download the template dns rc and svc file from
    39  
    40  [skydns-rc template](skydns-rc.yaml.in)
    41  
    42  [skydns-svc template](skydns-svc.yaml.in)
    43  
    44  ### Set env
    45  
    46  Then you need to set `DNS_REPLICAS` , `DNS_DOMAIN` , `DNS_SERVER_IP` , `KUBE_SERVER` ENV.
    47  
    48  ```
    49  $ export DNS_REPLICAS=1
    50  
    51  $ export DNS_DOMAIN=cluster.local # specify in startup parameter `--cluster-domain` for containerized kubelet 
    52  
    53  $ export DNS_SERVER_IP=10.0.0.10  # specify in startup parameter `--cluster-dns` for containerized kubelet 
    54  
    55  $ export KUBE_SERVER=10.10.103.250 # your master server ip, you may change it
    56  ```
    57  
    58  ### Replace the corresponding value in the template.
    59  
    60  ```
    61  $ 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
    62  
    63  $ sed -e "s/{{ pillar\['dns_server'\] }}/${DNS_SERVER_IP}/g" skydns-svc.yaml.in > ./skydns-svc.yaml
    64  ```
    65  
    66  ### Use `kubectl` to create skydns rc and service
    67  
    68  
    69  ```
    70  $ kubectl -s "$KUBE_SERVER:8080" --namespace=kube-system create -f ./skydns-rc.yaml
    71  
    72  $ kubectl -s "$KUBE_SERVER:8080" --namespace=kube-system create -f ./skydns-svc.yaml
    73  ```
    74  
    75  ### Test if DNS works
