CoreDNS is now running in the cluster.
|
||
|
|
It can be accessed using the below endpoint
|
||
|
|
{{- if contains "NodePort" .Values.serviceType }}
|
||
|
|
export NODE_PORT=$(kubectl get --namespace {{ .Release.Namespace }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ template "coredns.fullname" . }})
|
||
|
|
export NODE_IP=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
|
||
|
|
echo "$NODE_IP:$NODE_PORT"
|
||
|
|
{{- else if contains "LoadBalancer" .Values.serviceType }}
|
||
|
|
NOTE: It may take a few minutes for the LoadBalancer IP to be available.
|
||
|
|
You can watch the status by running 'kubectl get svc -w {{ template "coredns.fullname" . }}'
|
||
|
|
|
||
|
|
export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ template "coredns.fullname" . }} -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
|
||
|
|
echo $SERVICE_IP
|
||
|
|
{{- else if contains "ClusterIP" .Values.serviceType }}
|
||
|
|
"{{ template "coredns.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local"

It can be tested with the following:
|
||
|
|
|
||
|
|
1. Launch a Pod with DNS tools:
|
||
|
|
|
||
|
|
kubectl run -it --rm --restart=Never --image=infoblox/dnstools:latest dnstools
|
||
|
|
|
||
|
|
2. Query the DNS server:
|
||
|
|
|
||
|
|
/ # host kubernetes
