tower – Ansible dynamic inventory plugin for Ansible Tower.

New in version 2.7.

Synopsis

  • Reads inventories from Ansible Tower.
  • Supports reading configuration from both YAML config file and environment variables.
  • If reading from the YAML file, the file name must end with tower.(yml|yaml) or tower_inventory.(yml|yaml), the path in the command would be /path/to/tower_inventory.(yml|yaml). If some arguments in the config file are missing, this plugin will try to fill in missing arguments by reading from environment variables.
  • If reading configurations from environment variables, the path in the command must be @tower_inventory.
