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

Documentation

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.

Orchestration Supported Technologies

AWS:

GCP:

  • IAM Service Accounts
  • Network/Subnetworks
  • Storage Buckets

OpenStack:

  • Network/Subnet
  • Floating IP/Router/Port
  • User
  • Instance/Image
  • Load Balancer
  • Object Storage Container

Install

pip install cloudaux

For GCP support run:

pip install cloudaux\[gcp\]

For OpenStack support run:

pip install cloudaux\[openstack\]

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']

GCP Example

# 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)

from cloudaux.gcp.iam import list_serviceaccounts
from cloudaux.orchestration.gcp.iam.serviceaccount import get_serviceaccount_complete

@iter_project(projects=projects, key_file='/path/to/key.json')
def test_iter(**kwargs):
   accounts = list_serviceaccounts(**kwargs)
   ret = []
   for account in accounts:
     ret.append(get_serviceaccount_complete(service_account=account['name']))
   return ret

OpenStack Example

from cloudaux.openstack.decorators import _connect
conn = _connect(cloud_name, region, yaml_file):

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

@iter_account_region(account_regions=get_regions())
def list_networks(conn=None, service='network', generator='security_groups'):
    from cloudaux.openstack.utils import list_items
    list_items(**kwargs)

Orchestration Example

AWS IAM Role

from cloudaux.orchestration.aws.iam.role import get_role, FLAGS

# account_number may be extracted from the ARN of the role passed to get_role
# if not included in conn.
conn = dict(
    assume_role='SecurityMonkey',  # or whichever role you wish to assume into
    session_name='cloudaux',
    region='us-east-1'
)

role = get_role(
    dict(arn='arn:aws:iam::000000000000:role/myRole', role_name='myRole'),
    output='camelized',  # optional: {camelized underscored}
    flags=FLAGS.ALL,  # optional
    **conn)

# The flags parameter is optional but allows the user to indicate that 
# only a subset of the full item description is required.
# IAM Role Flag Options:
#   BASE, MANAGED_POLICIES, INLINE_POLICIES, INSTANCE_PROFILES, ALL (default)
# For instance: flags=FLAGS.MANAGED_POLICIES | FLAGS.INSTANCE_PROFILES

# cloudaux makes a number of calls to obtain a full description of the role
print(json.dumps(role, indent=4, sort_keys=True))

GCP IAM Service Account

from cloudaux.orchestration.gcp.iam.serviceaccount import get_serviceaccount_complete, FLAGS
sa_name = 'projects/my-project-one/serviceAccounts/service-account-key@my-project-one.iam.gserviceaccount.com'
sa = get_serviceaccount_complete(sa_name, flags=FLAGS.ALL, **conn_details)
print(json.dumps(sa, indent=4, sort_keys=True))

# Flag options for Service Accounts are BASE, KEYS, POLICY, ALL (default).

OpenStack Security Group

from cloudaux.orchestration.openstack.security_group import get_security_group, FLAGS

secgroup = get_security_group(result, flags=flags, **kwargs)

# The flags parameter is optional but allows the user to indicate that
# only a subset of the full item description is required.
# Security Group Flag Options:
#   RULES, INSTANCES (default)
# For instance: flags=FLAGS.RULES | FLAGS.INSTANCES
