Step-3: Copy id_rsa.pub key of Zabbix-Ansible-Ops-SSDN-236 and pest into /root/.ssh/authorized_keys of newly launched ssdnodes remote VM

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCPZVCJDflQS7nTKvbKN4IsCkt1fKixNbHm1AfxIwka+w3hQz26tMIGnl7oaLHmA2SFiOCR7CA5emG6z2TIN+JUi/1c63+7kNvgKJfokw/u4DEch/MIgv43pbL3j1Qy2dxIQ2k74Y0mtSjHpLbtImkFjCxPITrTjCopiUGBRBwZH/J6IEdJcDnyw/MWnzH/IR8Eo0UVjZ1wFYAhnvY71kNqB0QdOKvJABkVj341bQz3ukF3Q5uPK0IIa2D+vowjKtLswW5yUm9jZ87DvRmq3w2vvFP2kKZGGj/tNjRl5gP0pV75F+Vn1vMeYBO4Yc+wTn4SKjmdOuc+NtV8RVx3M6d5 root@zabbix-ansible-ops-ssdn-236

ssh root@209.182.234.xxx

Step-4: Set IP of remote VM IP into ansible hosts and inventory file

nano /etc/ansible/hosts
[servers]
209.182.234.xxx ansible_user=root

nano /etc/ansible/inventory
[servers]
209.182.234.xxx ansible_user=root

Step-5: Now set the username(s) (you want to create into new remote VM) in the ansible playbook: ssh-user-mgmnt.yml

nano /etc/ansible/ssh-user-mgmnt/ssh-user-mgmnt.yml
vars:

  azim
  imran
  mahrab
  mamun
  mim

ansible-playbook --check ssh-user-mgmnt.yml

Step-7: Finaly run the playbook and verify your access to the new VM using your username & key

$ ansible-playbook --i servers ssh-user-mgmnt.yml
$ ssh azim@209.182.234.xxx -p 3914
