TripleO undercloud ver 10 failure: undefined variable 'install.build'

[FedericoRessi]

When deploying undercloud version 10 on "clean" RHEL 7.4 virsh based hypervisor fails because install.build attribute is not defined.

• infrared version:
  • infrared --version: 2.0.1.dev1878
  • git describe: 2.0.0-1993-g33391dd
• component: tripleo-undercloud plugin:
  • plugins/tripleo-undercloud/deploy.yml
• hypervisor OS: RHEL 7.4 after fresh install using foreman service

How to reproduce

1) Checkout infrared source code:

git clone https://github.com/redhat-openstack/infrared.git
cd infrared
git checkout 2.0.0-1993-g33391dd

2) create a python 2.7 virtual env for infrared, activate it and update packages

virtualenv .venv
source .venv/bin/activate
pip install -U pip setuptools

3) Install infrared in the virtualenv

pip install -U .

4) Prepare a clean hypervisor machine with RHEL 7.4 5) Copy your SSH key to remote machine

ssh-copy-id -i ~/.ssh/id_rsa root@<your-hypervisor-host-address>

5) Install infrared plugins

infrared plugin add plugins/virsh
infrared plugin add plugins/tripleo-undercloud

6) Prepare hypervisor using infrared

infrared virsh --host-address <your-hypervisor-host-address> --host-key ~/.ssh/id_rsa --topology-nodes "undercloud:1,controller:1,compute:1" --host-user root

7) Deploy overcloud version 10

infrared tripleo-undercloud --version 10

Last step will fail here because install.build is undefined.

I had success deploying undercloud after applying this patch: infrared-313-patch.txt

While testing patch for this issue I hit Issue #314 which described workaround can be applied to test the fix for this issue.
