An **inventory** file. This can be mounted inside the container as a volume and specified with the `INVENTORY_FILE` environment variable. Alternatively you can serve the inventory file from a web server and use the `INVENTORY_URL` environment variable to fetch it. 1. **ssh keys** so that Ansible can reach your hosts.
