Lab 2.2-2.3 DNS Loss
When following the steps of this course to setup kubernetes cluster, the VM's are sabotaged by the scripts provided by this course, which damage/disable default DNS.
Steps to replicate:
-Setup VM's in designated environment (Ubuntu 18.04)
-VM's have good DNS, can ping www.google.com or each by master / minion hostname
-Run scripts for LFD259/SOLUTIONS/s_02/k8sMaster.sh and k8sSecond.sh to setup master and minion nodes
At this point I lose all DNS, preventing any further use of the course. I cannot get the Nginx image in lab 2.3 because that will not communicate with the image repository. I'm really not sure what to do to further investigate this or what is triggering this issue and would appreciate assistance.
