OpenStack Trove disk-image-builder

The documentation for this process absolutely sucks.. and the fact that no ones updated it (shame on me for even saying that about an opensource project that i can push a branch to…) is pitiful. So.. here’s some useful info for completing an image!

Useful post:

2: https://ask.openstack.org/en/question/95078/how-do-i-build-a-trove-image/

yum install epel-release git -y
git clone https://git.openstack.org/openstack/diskimage-builder
yum install python2-pip
pip install -r requirements.txt
python setup.py install

Now we clone the trove git repo and add the extra elements as a environment variable.

git clone https://github.com/openstack/trove.git
