!!!! Read before starting:     if ansible run as root >>>>> use root's   id_rsa   file !!!!

!!!! But if it's for Juniper, use the user account to log into the router !!!!

juniper.junos module does not send a file to the router, but use netconfig

1- create the Private key & Public key ( .pub) on the Client:       ssh-keygen
2- copy the public key to the server:               ssh-copy-id   or just a sftp
3- To set up SSH agent to avoid retyping passwords, you can do:
4- SSH test ( will ask for the passphrase once!)
5- check the Local keys:
6- check the Remote keys:

or just copy the file using  ( if ssh-copy-id not supported ):

scp id_rsa.pub  ansible@192.168.99.111:/var/home/ansible/

sftp ansible@192.168.99.11 ( then put /project/id_rsa.pub /var/home/ansible/id_rsa.pub )
