Hi, I am relatively new to Ansible and struggle to grasp how one should use dynamic inventories within playbooks or tools that call ansible-core. I have a python script that returns a valid json list of hostgroups and members which works with  
`ansible-inventory -i script.py -e hostgroup=webservers playbook.yml`.  
Is there any way to run this dynamic inventory within a play and pass it to a second play?

The only option I see now, is to run the inventory script with cmd module and use add\_host for the subsequent play.

Rgrds.

I never have to invoke my inventory - as long as your `ansible.cfg` points to the file/directory (`inventory = /opt/ansible/inventory/dynamic`), it should automatically use it.

Many ways, use `ansible-playbook -i script.py playbook.yml`. The `ansible-inventory` is there to test/verify your inventory is working, but the rest of ansible CLI tools that execute against hosts are able to take `-i` also (adhoc, console, playbook)
