esisdk 0.4.0

An SDK for building applications to work with ESI

esisdk

Unified SDK for ESI

Use the SDK in python scripts

Install ESI SDK:

python setup.py install

Create a connection to ESI SDK

There are several methods to establish a connection using the ESI SDK. Since the esi.connection.ESIConnection class inherits from openstack.connection.Connection, methods applicable for creating connections in the OpenStack SDK can also be used with the ESI SDK. Below are some common ways to create an ESIConnection:

Create a connection using only keyword arguments

from esi import connection

conn = connection.ESIConnection(
    region_name='example-region',
    auth={
        'auth_url': 'https://auth.example.com',
        'username': 'user',
        'password': 'password',
        'project_name': 'project_name',
        'user_domain_name': 'user_domain_name',
        'project_domain_name': 'project_domain_name'
    },
    interface='public'
)

Create a connection from existing CloudRegion

from esi import connection
import openstack.config

config = openstack.config.get_cloud_region(
    cloud='example',
    region_name='earth'
)
conn = connection.ESIConnectionn(config=config)

Make API calls

Detailed APIs can be found in the esi/lease/v1/_proxy.py file. Below are simple examples demonstrating lease resource CRUD operations.

import esi
import os

TEST_CLOUD = os.getenv('OS_TEST_CLOUD', 'devstack-admin')
conn = esi.connect(cloud=TEST_CLOUD)

# Create a lease
def lease_create(conn, resource_uuid, project_id, **kwargs):
    lease = conn.lease.create_lease(resource_uuid=resource_uuid,
                                    project_id=project_id,
                                    **kwargs)

# List leases
def lease_list(conn, **kwargs):
    leases = conn.lease.leases(**kwargs)

# Update a lease
def lease_update(conn, lease, **kwargs):
    lease_dict = conn.lease.update_lease(lease, **kwargs)

# Delete a lease
def lease_delete(conn, lease_id):
    leases = conn.lease.delete_lease(lease_id)
