Ansible - Inventory file format (INI YAML)

Updated:   |  Ansible articles

Tasks are run against target servers. Some Ansible documentation refers to the target servers as "hosts".


The default hosts file or your own inventory file can use different formats. The most commonly used formats are INI and YAML. Follow are example INI and YAML configurations.

Here is an example using the INI format.


And here is the YAML format.



Once the default hosts file or your own inventory file has been updated to contain managed nodes (e.g. target systems), you can run tasks against the managed nodes. For example, the following command would ping every managed node in your default hosts file.

ansible all -m ping


Which should return something like this. | SUCCESS => {
    "changed": false,
    "ping": "pong"
