I'm using Ansible to setup EC2 instances and deploy an app. There's a hosts script which gathers tags related servers and groups info. I'd like to run these actions as a single playbook, so

1. New instances are created if needed
2. Hosts script loads inventory (including servers' facts)
3. Deployment playbook works

However, inventory loaded in advance so there is no servers/groups data if servers created/updated during the play. I can 1) separate provision and deployment playbooks 2) use add\_host trick to emulate dynamic inventory when servers are updated, but there are drawbacks in those approaches.

Can I force Ansible to reload inventory? My test files are:
`hosts` script:

```
#!/bin/sh
echo `date` >> log.log
echo "{\"standalone\":[\"localhost\"]}"

```

Sample `playbook.yml`:

```
---
- hosts: all
  tasks:
    - name: show inventory_hostname
      command: echo {{ inventory_hostname }}

```

I run it `ansible-playbook -i hosts playbook.yml -v` and see **two** runs:

```
$> cat log.log
Thu Mar 12 09:43:16 SAMT 2015
Thu Mar 12 09:43:16 SAMT 2015

```

but I haven't found a command to double it.
