Inventory plugins are bits of code that will create inventory data for an Ansible execution. In many environments, the simple ini file-style inventory source and variable structure is not sufficient to represent the actual infrastructure being managed. In such cases, a dynamic inventory source is desired, one that will discover the inventory and data at runtime at every execution of Ansible. A number of these dynamic sources ship with Ansible, primarily to operate Ansible with the infrastructure built into one cloud computing platform or another.

- rax
- vagrant
- vmware
- windows_azure
