### Get the template file
|
|
|
|
First of all, download the dns template
|
|
|
|
[skydns template](/docs/getting-started-guides/docker-multinode/skydns.yaml.in)
|
|
|
|
### Set environment variables
|
|
|
|
Then you need to set `DNS_REPLICAS`, `DNS_DOMAIN` and `DNS_SERVER_IP` envs
|
|
|
|
```shell
|
|
$ 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
|
|
```
|
|
|
|
### Replace the corresponding value in the template and create the pod
|
|
|
|
```shell{% raw %}
|
|
$ sed -e "s/{{ pillar\['dns_replicas'\] }}/${DNS_REPLICAS}/g;s/{{ pillar\['dns_domain'\] }}/${DNS_DOMAIN}/g;s/{{ pillar\['dns_server'\] }}/${DNS_SERVER_IP}/g" skydns.yaml.in > ./skydns.yaml
|
|
|
|
# If the kube-system namespace isn't already created, create it
|
|
$ kubectl get ns
|
|
$ kubectl create namespace kube-system
|
|
|
|
$ kubectl create -f ./skydns.yaml{% endraw %}
|
|
```
|
|
|
|
