I need some help on this problem.
So, I'm using Ubuntu 16.04 and have one master and one worker.
My master node ip is 192.168.0.35
My worker node ip is 192.168.0.36
Both have static bridge enp0s3 connection, gateway 192.168.0.1, dns 126.96.36.199.
I changed my coredns pod configMap before.
There was an error which ImagePullBackoff status when i tried to pull image from docker to make a pod, but this only happened on my master node. On my worker node, all worked fine, no error and got running status. But this matter will be solved when i restart the master node, may it one times or more until all pods were running. After restart one times or more, i got running status on all pods.
Anybody know why did this happen? Is there a problem with my network configurations?
