Inventory

An inventory is a list of managed nodes, or hosts, that Ansible deploys and configures. The inventory can either be static or dynamic.

Convert INI to YAML

The most common format for the Ansible Inventory is the .ini format, but sometimes you might need the inventory file in the YAML format.
A .ini inventory file for example might look like this:

inventory.ini

[control]
controller ansible_host=localhost ansible_connection=local

[target]
rocky8 ansible_connection=docker

You can convert your existing inventory to the YAML format with the ansible-inventory utility.

ansible-inventory -i inventory.ini -y --list > inventory.yml

The resulting file is your inventory in YAML format:

inventory.yml

all:
  children:
    control:
      hosts:
        controller:
          ansible_connection: local
          ansible_host: localhost
    target:
      hosts:
        rocky8:
          ansible_connection: docker

Custom dynamic inventory

In case no suitable inventory plugin exists, you can easily write your own. Take a look at the Ansible Development - Extending section for additional information.
