OpenStack offers an integrated command-line client, allowing you to use simple commands to access the project API (collection of settings, credentials, and metadata about the application(s) you're working on). Additionally, the majority of OpenStack projects include a command-line client for each service. For instance, a nova command-line client is offered by the Compute service. The commands can be used to automate processes directly from the command line or by incorporating them into the code scripts. You can execute these commands on any computer by just entering your OpenStack credentials.
In this tutorial, we'll help you to create your own resources as a cloud user via CLI.
Step 1: Log in to
Step 2: Download the rc file
An OpenStack rc file, also known as an openrc.sh file is a type of environment file that must be created in order to specify the necessary environment variables for the OpenStack command-line clients. You may download the file from your . The login information for all OpenStack services is stored in this project-specific environment file. The variables allow communication between OpenStack services running in the cloud and OpenStack client commands.
Download the file in your computer, as shown in the figure below:
Step 3: Working on the terminal
After setting up, run the following commands:
1. Enter into the root user:
2. Install pip for python 3 with all the required dependencies and python modules:
3. Execute the following command to install the OpenStack client in a virtual environment.
Step 4: Uploading the rc file
You may directly upload the already downloaded rc file in your code editor.
Step 5: Copying rc file
As we are performing all the functions in the root user, you need to copy your rc file from /home/ubuntu to root, using the following command:
2. Use the following command to list all the files in the root user directory. Below screenshot highlights the copied rc.sh file.
Step 6: Execute the rc file
Source the Linux shell, on which you want to run the OpenStack commands, using the command below:
2. Enter your Openstack console password.
Step 7: Access OpenStack with CLI
Open the code editor of your choice that allows SSH key authentication because it is the only way to access OpenStack instances. Here we are using MobaXterm, which you may download from .
The OpenStack is now ready to work directly through CLI. Now, you can access and manage your servers, instances, volumes, networks, IPs, security groups etc with the suitable commands. You can refer to the official for the same.
