cloudaux

Cloud Auxiliary is a python wrapper and orchestration module for interacting with cloud providers.

NOTE: What are we supporting?

CloudAux was initially developed to provide convenience wrappers for common patterns when working with cloud infrastructures (like role assumption, and multi-regionality). It also contained some convenience functions to describe entire resources with the wrappers to fetch the full resource configuration details.

However, over time, we have stopped relying on the resource configuration wrapper capabilities and instead are only supporting the AWS convenience decorators, such as sts_conn, and paginated to name a few. If you wish to make use of CloudAux, simply wrap your boto calls in a function with the decorators applied to them.

NOTE: Python 2 Deprecation

Python 2 support has been dropped as of version 1.9.0. For projects that still require Python 2 support, please use the latest 1.8.x builds.

Features

AWS:

• intelligent connection caching.
• handles pagination for certain client methods.
• rate limit handling, with exponential backoff.
• multi-account sts:assumerole abstraction.
• orchestrates all the calls required to fully describe an item.
• control which attributes are returned with flags.

GCP:

• choosing the best client based on service
• client caching
• general caching and stats decorators available
• basic support for non-specified discovery-API services
• control which attributes are returned with flags.

OpenStack:

• intelligent connection caching.
• generalized OpenStack SDK generator usage.
• orchestrates all the calls required to fully describe an item.
• control which attributes are returned flags.

Examples

AWS Example

# Using wrapper methods:
from cloudaux.aws.sqs import get_queue, get_messages
conn_details = {
    'account_number': '111111111111',
    'assume_role': 'MyRole',
    'session_name': 'MySession',
    'region': 'us-east-1'
}
queue = get_queue(queue_name='MyQueue', **conn_details)
messages = get_messages(queue=queue)


# Using the CloudAux class
from cloudaux import CloudAux
CloudAux.go('kms.client.list_aliases', **conn_details)

ca = CloudAux(**conn_details)
ca.call('kms.client.list_aliases')


# directly asking for a boto3 connection:
from cloudaux.aws.sts import boto3_cached_conn
conn = boto3_cached_conn('ec2', **conn_details)


# Over your entire environment:
from cloudaux.decorators import iter_account_region

accounts = ['000000000000', '111111111111']

conn_details = {
    'assume_role': 'MyRole',
    'session_name': 'MySession',
    'conn_type': 'boto3'
}

@iter_account_region('kms', accounts=accounts, regions=['us-east-1'], **conn_details)
def list_keys(conn=None):
    return conn.list_keys()['Keys']

# If you want your role to be read-only, you can assume your role and add the read_only flag to connection details
# to inherit the AWS ReadOnlyAccess policy. This flag defaults to False
# The permissions from the role being assumed will be limited to Read and List only
conn_details = {
    'account_number': '111111111111',
    'assume_role': 'MyRole',
    'session_name': 'MySession',
    'region': 'us-east-1',
    'read_only': True
}

GCP Example -- DEPRECATED - NO LONGER SUPPORTED

# directly asking for a client:
from cloudaux.aws.gcp.auth import get_client
client = get_client('gce', **conn_details)

# Over your entire environment:
from cloudaux.gcp.decorators import iter_project

projects = ['my-project-one', 'my-project-two']

# To specify per-project key_files, you can do thie following:
# projects = [
#  {'project': 'my-project-one', key_file='/path/to/project-one.json'},
#  {'project': 'my-project-two', key_file='/path/to/project-two.json'}
# ]
#
# To specify a single key_file for all projects, use the key_file argument
# to the decorator
# @iter_project(projects=projects, key_file='/path/to/key.json')
#
# To use default credentials, omit the key_file argument
# @iter_project(projects=projects)
