OpenStack Client is a command-line tool for OpenStack that brings the command set for Compute, Identity, Image, Object Storage and Block Storage APIs together in a single shell with a uniform command structure. The OpenStack client enables you to interact with OpenStack services over the network via API call.

A pre-requisite for this setup is a working OpenStack Cloud platform. You can check our OpenStack guides for how to articles. If you’re a developer and would like to contribute, the code is hosted on OpenStack’s Git server.

OpenStack Installation guide: Install OpenStack Victoria on CentOS 8 With Packstack

Step 1: Install Python Pip tool

Some Linux distributions include packaged versions of the OpenStack command-line clients that you can install directly, but we’ll install from Pip. Install pip through the package manager for your system:

------------ Install pip on Debian / Ubuntu ----------
$ sudo apt-get -y update
$ sudo apt-get -y install python-dev python-pip
$ sudo pip install --upgrade pip

------------ Install pip on CentOS / RHEL ----------
$ sudo yum -y install python-devel python-pip
$ sudo pip install --upgrade pip

------------ Install pip on Arch / Manjaro ----------
$ sudo pacman -Syy
$ sudo pacman -S python-pip
$ sudo pip install --upgrade pip

--------- Install pip on macOS ----------------
$ sudo easy_install pip

Confirm version of pip installed.

$ pip --version
pip 19.1.1 from /usr/lib/python3.7/site-packages/pip (python 3.7)

Step 2: Install OpenStack Client on Linux

After installation of Pip, proceed to install OpenStack command-line clients.

sudo pip install python-openstackclient

Display more information about installed Openstack Command Line client.

$ pip show python-openstackclient
Name: python-openstackclient

Required-by: 

You should have openstack command in your PATH.

$ which openstack
/usr/bin/openstack

Step 3: Configure OpenStack Client on Linux

You can pull OpenStack configuration file from OpenStack Director or create one if you have correct access credentials.

$ nano ~/.keystonerc
unset OS_SERVICE_TOKEN
    export OS_USERNAME='admin'
    export OS_PASSWORD='adminpassword'
    export OS_AUTH_URL=http://192.168.100.10:5000/v3
    export PS1='[\[email protected]\h \W(keystone_admin)]\$ '
    
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_IDENTITY_API_VERSION=3

Update variables to match your OpenStack environment. When done, source the file to start using openstack command line tool to administer OpenStack Cloud.

$ source ~/.keystonerc

Your Shell prompt should change to.

[\[email protected]\h \W(keystone_admin)]$ 

Run openstack command to confirm it is working.

[\[email protected]\h \W(keystone_admin)]$ openstack network list

Step 4: Enable OpenStack Bash completion

Use the openstack complete command to generate a bash-completion script.

openstack complete | sudo tee /etc/bash_completion.d/osc.bash_completion > /dev/null

Logout

$ logout
or
$ exit

Then login again to enjoy OpenStack bash completion.

$ openstack network <TAB>
agent     create    flavor    log       meter     rbac      service   show      trunk     
auto      delete    list      loggable  qos       segment   set       subport   unset
