The Avere virtual FXT (vFXT) Python library and vfxt.py command line utility provide the ability to create, extend, destroy, start, and stop vFXT clusters in all supported cloud environments.

User Guide

You can find the user documentation in this repository under docs.

Installation

NOTE: Only Azure options are supported at this time. Using vFXT with other cloud services is deprecated.

With pip

pip install vFXT

From source

Use pip within the source directory to install all of the required dependencies. The use of --user is encouraged. This installs the script vfxt.py in ~/.local/bin on Unix (~/Library/Python/{major.minor}/bin on Mac) and %APPDATA%/Python/Python{major minor}/bin on Windows. This path will need to be added to the PATH environment variable.

pip install --user .

Authentication requirements - specific for each service backend

  • AWS: requires the access key/secret access key pair
  • Azure: requires an AD application/service principal
  • GCE: requires a service account with the JSON key file

vFXT Library

Azure example:

from vFXT.cluster import Cluster
from vFXT.msazure import Service

azure = Service(subscription_id='', tenant_id='',
    application_id='', application_secret='',
    resource_group='', storage_account='',
    location='', network='', subnet='',
)
cluster = Cluster.create(azure, 'Standard_D16s_v3', 'averecluster', 'PLACEHOLDER')

with open('/home/user/.ssh/id_rsa.pub','r') as f: # must be rsa
    sshpubkey = f.read()
client = ServiceInstance.create(azure, 'Standard_DS1', 'client1', 'debian:debian-10:10:latest', admin_ssh_data=sshpubkey)

GCE example (DEPRECATED):

from vFXT.cluster import Cluster
from vFXT.gce import Service

gce = Service(client_email='fill me in', key_file='path-to.json', zone='us-central1-b', project_id='fill me in', network_id='fill me in')
cluster = Cluster.create(gce, 'n1-highmem-8', 'averecluster', 'PLACEHOLDER')
cluster.stop()
cluster.destroy()

with open('/home/user/.ssh/id_rsa.pub','r') as f:
  sshpubkey=f.read()
  sshpubkey='username:{}'.format(sshpubkey)

from vFXT.serviceInstance import ServiceInstance
# via ServiceInstance which calls the backend .create_instance()
client = ServiceInstance.create(gce, 'n1-standard-1', 'client1', 'projects/debian-cloud/global/images/debian-10-buster-v20200210', metadata={'ssh-keys':sshpubkey}, tags=['client'])

client_instance.destroy()

AWS example (DEPRECATED):

from vFXT.cluster import Cluster
from vFXT.aws import Service

aws = Service(region='fill me in', access_key='fill me in', subnet='subnet-f66a618e', secret_access_key='fill me in')

cluster = Cluster.create(aws, 'r3.8xlarge', 'averecluster', 'PLACEHOLDER')
try:
  cluster.make_test_bucket(bucketname='averecluster-s3bucket', corefiler='averecluster-s3bucket')
  cluster.add_vserver('vserver')
  cluster.add_vserver_junction('vserver', 'averecluster-s3bucket')
except Exception as e:
  ...

from vFXT.serviceInstance import ServiceInstance
# via ServiceInstance which calls the backend .create_instance()
client = ServiceInstance.create(aws, 'c3.xlarge', 'client1', 'ami-b9faad89', key_name="aws_ssh_keyname")

General example:

To load an existing, running cluster:

Cluster.load(service, mgmt_ip='fill me in', admin_password='fill me in')

To instantiate a cluster that may be offline:

cluster = Cluster(gce, nodes=['xxx', 'xxx', 'xxx'], admin_password='xxx', mgmt_ip='xxx')
if cluster.is_off():
  cluster.start()
elif not cluster.is_on() and not cluster.is_off()
  # some nodes are offline, some are online
  cluster.status()

To serialize a cluster:

import json
json.dumps(cluster.export())

cluster.export() emits
{'nodes': [u'node-1', u'node-3', u'node-2'], 'admin_password': 'pass', 'mgmt_ip': '10.1.1.1'}

# To recreate the object:
cluster = Cluster(service, **{'nodes': [u'node-1', u'node-3', u'node-2'], 'admin_password': 'pass', 'mgmt_ip': '10.1.1.1'})

# The same with your service object:
service_data = service.export()
service = Service(**service_data)

Testing

Run the unit test suite

python setup.py test

Or run one test at a time

python setup.py test -s tests.GCE_test

The unittest configuration is found in tests/test_config.json. Set up credentials and existing infrastructure to verify against in the configuration prior to running.

Example vfxt.py utility invocation

The first part of the invocations are the cloud-type and the authentication options. Following those, the action and any related action options.
