ssh: Could not resolve hostname node01: Name or service not known
@oshratl Hi and welcome to the Forum 
You need to add the ip address to your /etc/hosts file or just use the ip address going forward.
Is this Step 3 of Exercise 5 in Section 7? It’s the only reference I’ve found in my Workbook for KUB201v1 to ssh root@node1.
If so, it says to enter ssh root@node1.example.com. My guess is the /etc/hosts file doesn’t have an alias of just node1.
