title: K8s coredns and flannel nameserver limit exceeded
body: <p>i have been trying to setup k8s in a single node,everything was installed fine. but when i check the status of my kube-system pods, </p>
  
  <p><strong>CNI -> flannel</strong> pod has <strong>crashed</strong>, reason ->  Nameserver limits were exceeded, some nameservers have been omitted, the applied nameserver line is: x.x.x.x x.x.x.x x.x.x.x</p>
  
  <p><strong>CoreDNS</strong> pods status is <strong>ContainerCreating</strong>.</p>
  
  <p>In My Office, the current server has been configured to have an static ip and when i checked <strong>/etc/resolv.conf</strong></p>
  
  <p>This is the output</p>
