ValueError regarding to shlex.py with dynamic inventory

[Alexander Winkler]

Hello,

I am currently writing an dynamic inventory to query out central database (CMDB. 

Regarding to http://docs.ansible.com/developing_inventory.html, I am implementing the _meta field for host variables. As far as I understood, "_meta" resolves in the function "--host" to be deprecated. So i just wrote a 'stupid' script without any parameters. 

My output looks like this:

{

    "ungrouped": {

        "hosts": [

            "ServerA",

            "ServerB"

        ]

    },

    "_meta": {

        "hostvars": {

            "ServerA": {

                "ansible_ssh_host": "192.168.0.1"

            },

            "ServerB": {

                "ansible_ssh_host": "192.168.0.2"

            }

        }

    }

}

Everything should be fine. But running ansible produces the following error (Ignore the first 2 lines. Those are warnings regarding to the SLES version of libraries):

user@host ~/git/ansible $ ansible-playbook site.yml -i /tmp/dyn_cmdb_inv.py

    raw = self.read_token()

  File "/usr/lib64/python2.6/shlex.py", line 172, in read_token

    raise ValueError, "No closing quotation"

ValueError: No closing quotation

Do you have any hint, why this error is produced? All quotations and formats are correct. The output is generated in python with "print (json.dumps(inventory, cls=DateEncoder, indent=4))", while "inventory" is a dictionary.

Thank you.

From that traceback, it appears as though your inventory script is being parsed by the ini parser.

That is an indication that your inventory script has not been set as executable.  (chmod +x /path/to/inventory/script)

Ansible determines whether it is an ini file or script by detecting if the file is executable.

Hello Matt,

Just such a simple solution didn't come into my mind. It works now. Thank you!
