This is my playbook to configure the basic stuff in my servers

1. Configure ssh-key access to the servers
2. Add ssh identyties to your ssh-agent. To do that:
   • Execute eval "$(ssh-agent -s)". It should be like:

     $ eval "$(ssh-agent -s)"
     > Agent pid XXXXX

   • And then run ssh-add ~/.ssh/i<key name>
3. Install ansible
4. Create yout hosts inventory, or global one in /etc/ansible/hosts or a local one. As an example:

   [all]
   192.168.1.254
   192.168.1.253
   

5. Run the following to clarify if the server is working with ansible:

   ansible -i hosts all -u <user in the server> -m ping
   

   At this point, if all is working fine, you will se this:

   192.168.1.254 | SUCCESS => {
       "ansible_facts": {
           "discovered_interpreter_python": "/usr/bin/python3"
       },
       "changed": false,
       "ping": "pong"
   }
   

ansible-playbook -i <inventory> -u <user> -K --extra-vars "ssh_port=<port>" main.yaml
