Exercise 3.3: Finish Cluster Setup - Problem with coreDNS

Hello folks,
I am following Ex 3.3 step 6 to determine if the DNS and Calico pods are ready for use, and I am getting an error as below. Any ideas are welcome please!
~$ kubectl get pods --all-namespaces
NAMESPACE NAME READY STATUS RESTARTS AGE
kube-system calico-node-bdqnk 1/2 CrashLoopBackOff 1905 6d18h

Hello,
There are a few reasons the pods are not fully running. It depends on how far along in the labs you may be as there are some other steps to run in order that you have two nodes and both are willing to run all pods.
When you ran kubeadm init --kubernetes-version 1.12.1 --pod-network-cidr 192.168.0.0/16 did you have any errors?
Did you find any errors when you did the kubeadm join from the worker node?
Were you able to remove the taints on both nodes?
Regards,
Hi, some of these errors are expected in step 6, then step 7 helps with fixing them.
Are your nodes local VMs or cloud VM instances?

I have a similar problem. coreDNS is not starting up.
I am running the two nodes on bare metal. I am still in LAB 2.1 but everything installed and set up without error.
When I describe the coreDNS pod I have the followin in the logs:
@bryonbaker ,
You can try to delete the 2 coredns pods, and they will be re-created.
Are you in Lab 2.1 of LFD259?
Thanks,
-Chris
