6/22/2020
I would like to view the configuration file of CoreDNS service.
When i look in to the coredns deployment file it is shown as
spec:
containers:
- args:
- -conf
- /etc/coredns/Corefile
image: k8s.gcr.io/coredns:1.6.7
imagePullPolicy: IfNotPresent- Is the /etc/coredns/Corefile inside the container
- If yes,How to view it.. i am unable to get in to the coredns container
If i change the coredns config map file, will the /etc/coredns/Corefile also change

Basically Corefile is included in coredns which is a kind of ConfigMap in Kubernetes. 1. To view it you have to check ConfigMap resourse.
kubectl get ConfigMap coredns -n kube-system -o yaml2.If you change coredns ConfigMap data Corefile then /etc/cordns/Corefile will be changed also.you can check this document.
apiVersion: v1
kind: ConfigMap
metadata:
name: coredns
namespace: kube-system
data:
Corefile: |
