Error when using Tuskar to redeploy the overcloud

[Ronelle Landy]

I used Tuskar (installed on Fedora 20) to deploy the overcloud. I then deleted that original overcloud and removed the baremetal nodes. Afterwards, I used Tuskar to redploy the same overcloud. 'tuskar overcloud-create' returns warnings and errors, yet the overcloud continues to deploy. See commands and output copied below:

This issue also related to tuskarclient, because (as we can see in traceback) error from pythonclient hides the original exception.

Seems to be, that this error in pythonclient is appeared after the patch https://review.openstack.org/#/c/87315/ (Revert "Use HTTPClient from common apiclient code") was merged. So now tuskarclient use `httplib` library (instead or `request`) for http request. But from_response() method from tuskarclient/openstack/common/apiclient/exceptions.py file works correctly, when we put there response from `requests` library.

Interesting. It looks like the an error was returned by the API but the tuskarclient's error handling failed and thus has hidden the original error.

How did you delete the overcloud?

[Ana Krivokapić (akrivoka)]

I'm seeing the same traceback when trying to re-deploy using Tuskar-UI.

What I did:

- installed devtest
- ssh'ed into undercloud and heat stack-delete overcloud
- tryed to re-deploy overcloud using the UI -> error with the above traceback

    Pass the requests.Response object to from_response()

    from_response() method expects a requests.Response object, so we need
    to convert the existing httplib.HTTPResponse instance to requests.Response.

In Juno, Tuskar is no longer delegating calls to Heat. The caller should go to Heat directly with the templates provided by Tuskar. Closing this out as this workflow no longer exists.

I added the fix, but I am still getting the same error when trying to add a new compute node.
