There is no mention of where to find kube-system.yaml, and it's not necessary with kubectl 1.2. You can just create the namespace directly.
1.1 KiB
1.1 KiB
Get the template file
First of all, download the dns template
Set environment variables
Then you need to set DNS_REPLICAS, DNS_DOMAIN and DNS_SERVER_IP envs
$ 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
$ 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 %}
Test if DNS works
