I had followed the installation process as described in the blog for installing kubernetes on Ubuntu VM.

I am getting the pod status as this... coredn issues.

Hey @Raj, are you using Calico or flannel?

Hi Kalgi. I tried with both calico and flannel.

have installed ubuntu 16.04.5 Desktop version in a VM and tried the procedure outlined in the blog.


The installation works fine when I install using flannel and also change the proxy to using the command:

     kubectl edit cm coredns -n kube-system

My concern is whether there would be any implication of changing the proxy as mentioned above.

Alright, execute this command and post the output:

kubectl -n kube-system describe pod <coredns-pod-name>
Hey @Raj, any progress with this?
Sorry Kalgi. Thanks for the follow-up.

I got shifted to another project and so couldn't continue with Kubernetes as of now.

Thanks a ton.
Happy to help @Raj, come back whenever you're stuck :)

Hey @Balaji, can you show your error log?
Also, is your coreDNS in CrashLoopBackOff state or pending state?
