How to script connection of 2 servers via ssh?

Question

linux

Tell me please.
I create 2 cars as a vagrant. The task is for the script to generate ssh keys itself (I did this) and send them to the authorized_keys file. Sending to another machine is not a problem, scp will help. But I want it to be sent immediately without a password, because the script is not executed. Or how it is possible to bypass this situation?

Answer 1

Generate keys before creating two machines and implement immediately upon creation.
Or copy by password using some expect thread.
