Do dynamic inventories support command line arguments?

Hi All,
At http://docs.ansible.com/ansible/intro_dynamic_inventory.html, about halfway down, there's an example that reads:

    ansible-playbook -i 'ec2.py --profile prod' myplaybook.yml

which suggests that it's possible to pass arguments to dynamic inventory programs.

In real life, I can't seem to get it to work. Is the just a bad example or is there a trick that I'm missing?

Thanks,

That should not be possible. I would say that is a bad example.

You could use some wrapper script(s) as inventory source for that…

@esco real : The question remains the same. How to pass a command line argument to that wrapper script then?

You don’t. As of now, the recommended way to provide configuration to an inventory script is either via configuration file, or via environment variables.

As of now, there is no way to pass arguments directly to a dynamic inventory script.

As of now, the recommended way to provide configuration to an
inventory script is either via configuration file, or via environment
variables.

As of now, there is no way to pass arguments directly to a dynamic
inventory script.

We've done things like this by having a default 'hosts' wrapper script
that calls our dynamic inventory script, and then other wrapper scripts
that call the dynamic inventory script with arguments, so you can add
'--inventory other-wrapper' or prefix 'ANSIBLE_HOSTS=other-wrapper' to get
the other wrapper, which passes along the command line argument.

If you want to be able to specify an arbitrary argument on the command
line on the fly, that won't work; but if you've got a few typical
command-line arguments you want to pass, something like this can work.
