DevStack, as we have already discussed, is a script that installs the other OpenStack components in a development environment. There are several modes in which DevStack can be installed, but the only thoroughly tested mode is the All-In-One Single box installation.
The DevStack script itself is located on the GitHub and needs to be pulled from there. This ensures that we always have the latest script.
DevStack can be downloaded by the git clone
command. We will clone that in our home directory.
cd ~ git clone https://git.openstack.org/openstack-dev/devstack
This will clone the DevStack project onto the local devstack
folder. Since we are using a proxy server, this may not work right off the bat. If you don't have a proxy server, then you can skip this section.
