Python is an excellent language for interacting with OpenStack, an open-source cloud platform. Here's a simple example of how to use Python with OpenStack:

Prerequisites

   pip install python-openstackclient

Example 1: Creating a Virtual Machine (VM)

import os
from openstack import connection
Set up your environment variables
auth_url = 'https://your-openstack-url.com/v3'
username = 'your-username'
password = 'your-password'
Establish a connection to OpenStack
conn = connection.Connection(
auth_url=auth_url,
username=username,
password=password,
app_name='your-app-name',
)
Create a new VM
vm = conn.compute.create_server(name='my-new-server', image='my-image-id', flavor='m1.small')
Get the ID of the created VM
server_id = vm.id
print(f'Created server {server_id} successfully!')

Example 2: Listing All Flavors (Instance Types)

import os
from openstack import connection
Set up your environment variables
auth_url = 'https://your-openstack-url.com/v3'
username = 'your-username'
password = 'your-password'
Establish a connection to OpenStack
conn = connection.Connection(
auth_url=auth_url,
username=username,
password=password,
app_name='your-app-name',
)
List all available flavors (instance types)
flavors = conn.compute.flavors.list()
for flavor in flavors:
print(f'Flavor ID: {flavor.id}, Name: {flavor.name}')

Example 3: Getting Details of a Specific Server

import os
from openstack import connection
Set up your environment variables
auth_url = 'https://your-openstack-url.com/v3'
username = 'your-username'
password = 'your-password'
Establish a connection to OpenStack
conn = connection.Connection(
auth_url=auth_url,
username=username,
password=password,
app_name='your-app-name',
)
Get the ID of the server you want to retrieve details for
server_id = 'your-server-id'
Retrieve details of the specific server
server_details = conn.compute.get_server(server_id)
print(f'Server {server_id} is running with IP address: {server_details.ip}')

These examples demonstrate basic usage of Python with OpenStack. You can find more information and tutorials on the official OpenStack documentation website.

Please note that these examples are just a starting point, and you should adjust them according to your specific needs and environment variables.

Python OpenStack client

The Python OpenStack client!

The OpenStack client for Python is a set of libraries that allow you to interact with OpenStack services, such as Nova (compute), Glance (images), and Keystone (identity). With these libraries, you can create, list, update, and delete resources in OpenStack.

Here are the key benefits of using the Python OpenStack client:

Some examples of what you can do with the Python OpenStack client:

from openstack import client
keystone = client.KeystoneClient('https://your-keystone-url.com', 'username', 'password')
nova = client.NovaClient(keystone)
server = nova.servers.create(
name='my-server',
image_id='my-image-id',
flavor_id='my-flavor-id'
)

from openstack import client
glance = client.GlanceClient('https://your-glance-url.com', 'username', 'password')
images = glance.images.list()
for image in images:
print(image.name, image.id)

from openstack import client
nova = client.NovaClient(keystone)
server = nova.servers.get('my-server-id')
print(server.name, server.status)

The Python OpenStack client is a powerful tool that allows you to interact with your OpenStack infrastructure programmatically. With it, you can automate tasks, build applications, and gain insights into your cloud resources.
