coredns crashloopbackoff in kubernetes

Question

I have setup kubernetes in ubuntu 16.04. I am using kube version 1.13.1 and using weave for networking. I have initialized the cluster usi

Answer 1

I have resolved this issue. In my case I had below contents of /etc/resolv.conf

nameserver     127.0.1.1

I first used the below command to get the correct IP as the device was in client's network.

nmcli device show  | grep IP4.DNS

After this I updated the file /etc/resolvconf/resolv.conf.d/head with below contents

nameserver    192.168.66.21

and then run the below command to regenerate the resolv.conf

sudo resolvconf -u

After this I had below contents in /etc/resolv.conf:

nameserver    192.168.66.21
nameserver    127.0.1.1

I then deleted the coredns pods and everything worked fine. Thanks.
