Notes

  • Under [instances] group in inventory/hosts files please make sure to add IPs or DNS of target instances.
  • Update the varibale "user_name" and "user_des" as per requirements. You can add multiple values as well to run the action for mutiple users at a time.
  • Make sure to create a directory under "sshkeys" directory of same name as user name and put its SSH pub key under it.
  • I have tested this on AWS instances as target instances so I have used ec2-user. Please make sure to use appropriate user in "ssh.yml" who has access to target servers and the machine from where you will run Ansible should have passwordless access to target servers.
