Seeing "Specified limit does not match any hosts." on passing hosts file

[smalleni]

Hi, on passing a host file when creating the runner object I see "Specified limit does not match any hosts." Any clue what I'm missing? The host file looks as follows: [undercloud] undercloud [controller] overcloud-controller-0 [compute] overcloud-compute-0 overcloud-compute-1 Help is greatly appreciated. Thanks!

[jtyr]

Please could you provide more details? Especially whether you defining the equivalent of --limit in the options parameter of the Runner()?

@jtyr Hey...I'm trying to use your script as is, but changing the playbook and the hosts file which looks like what I pasted above. Not sure what else is required or what I'm missing. Thanks!

[jtyr]

You have to specify for which hosts you want to run your playbook. That should be done by specifying the right subset parameter in the Runner(). in your case it could look like this:

runner = Runner(
        playbook='site.yaml',
        hosts='hosts',
        display=display,
        options={
            'subset': 'compute',
        },
    )

Thank you. Got past that. Unfortunately the Ansible api is poorly documented :/. Seeing this now..

I changed verbosity to 3 and still this is all I see. Any help/pointers would be greatly appreciated

[jtyr]

Try verbosity 5.

[smalleni]

same thing :/ any other details that would be of help?

[jtyr]

As you said, the Ansible API is not very well documented. Unfortunately the only way how to make things working is to look how Ansible is doing it in their implementation.

@smalleni did you end up finding a solution? Getting the same problem

[andrewklau]

Resolved it by specifying: 'connection': 'smart' or 'connection': 'ssh'
