Installing the Openstack clients on Linux

This will help you get the Openstack clients working on Linux using Python.

Follow the instructions below at your own risk.

Task	Command
Optional Virtualenv creation	⁺Though not strictly necessary, we recommend using virtualenv to increase the stability of the openstack cli tools.
Create a directory for the project (cd to your preferred directory first)⁺	`mkdir <project_name>`
Change to the project directory	`cd <project_name>`
Install the VirtualEnvironment packages	`sudo easy_install virtualenv`
Start the VirtualEnvironment software	`virtualenv <project_name>`
Activate the VirtualEnvironment for the project	`source <project_name>/bin/activate`

DEPRECATED – This step is only necessary for Openstack clients < v4.0. The current production version is 4.x which uses Python 3. Make sure you have Python 2 installed	→ This should already be installed by your operating system. Openstack CLI clients MUST be installed with Python2's pip! check your default Python version with: python --version
Install the OpenStack clients	`For modern clients:` `pip3 install python-openstackclient` `For Openstack clients < v4.0:` `pip install python-openstackclient` `Additional clients that may also be useful depending on your custom needs are:` python-swiftclient, python-heatclient, python-magnumclient, python-manilaclient `For current users, clients that you likely no longer need to install are:` python-keystoneclient, python-novaclient, python-neutronclient, python-cinderclient, python-glanceclient
Set up your OpenStack credentials See Setting up openrc.sh for details.	`source .openrc`
Test an Open Stack command	openstack flavor list
Following future OpenStack updates, all installed `pip` modules can be updated with this command:	`pip freeze --local \| grep -v '^-e' \| cut -d = -f 1 \| xargs -n1 pip install -U`
