Inventories

• Inventory files may simply consist of a list of hostnames but can be much more robust

• It is also possible to define groups of hosts, host or group level variables, and groups of groups withing the inventory

• There are a number of variables that may be used within the inventory to control how ansible connects to and interacts with target hosts

• Commands to call ansible with ping module:

  • ansible innaghiyev1c.mylabserver.com -m ping -k - call ping module on innaghiyev1c.mylabserver.com host. Where -m ping is ping module and -k is key for asking password
  • ansible all -m ping -k - call all defined hosts in your inventory list /etc/ansible/hosts/
  • ansible -i inv.ini httpd -m ping -k - where -i - inventory file place, httpd hosts group name inside of inv.ini file

Output:

innaghiyev1c.mylabserver.com | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": false,
    "ping": "pong"
}
