VMware vSphere Connector Module for Python

vConnector - VMware vSphere Connector Module for Python
=======================================================

vConnector is a wrapper module around
`pyVmomi VMware vSphere bindings <https://github.com/vmware/pyvmomi>`_,
which provides methods for connecting and retrieving of
objects from a VMware vSphere server.

The purpose of vConnector is to provide the basic primitives for
building complex applications. vConnector can also be used for
managing the user/pass/host credentials for your vSphere environment
using an SQLite database, which in turn can be shared between
multiple applications requiring access to your vSphere environment
through a common interface.

Requirements
============

* `Python 2.7.x <https://www.python.org/>`_
* `docopt <https://github.com/docopt/docopt>`_
* `pyVmomi <https://github.com/vmware/pyvmomi>`_
* `tabulate <https://pypi.python.org/pypi/tabulate>`_

Contributions
=============

vConnector is hosted on
`Github <https://github.com/dnaeon/py-vconnector>`_. Please contribute
by reporting issues, suggesting features or by sending patches
using pull requests.

Installation
============

The easiest way to install vConnector is by using ``pip``:

.. code-block:: bash

$ pip install vconnector

In order to install the latest version of vConnector from the
Github repository simply execute these commands instead:

.. code-block:: bash

$ git clone https://github.com/dnaeon/py-vconnector.git
$ cd py-vconnector
$ python setup.py install

Applications using vConnector module
====================================

* `vPoller - Distributed vSphere API Proxy <https://github.com/dnaeon/py-vpoller>`_
* `vEvents - VMware vSphere Events from the command-line <https://github.com/dnaeon/py-vevents>`_

Using the vconnector-cli tool
=============================

Using the ``vconnector-cli`` tool you can manage the user/pass/host
credentials of your vSphere environment. The ``vconnector-cli`` tool
stores this information in an SQLite database file,
which also makes it easy to be shared between applications.

First, initialize the vConnector database by executing the
command below:

.. code-block:: bash

$ vconnector-cli init

Here is how to add a new vSphere host to the vConnector database:

.. code-block:: bash

$ vconnector-cli -H vc01.example.org -U root -P p4ssw0rd add

Here is how to update an already existing vSphere host
from the vConnector database:

.. code-block:: bash

$ vconnector-cli -H vc01.example.org -U root -P newp4ssw0rd update

Here is how to remove a vSphere host using vconnector-cli:

.. code-block:: bash

$ vconnector-cli -H vc01.example.org remove

Here is how to enable a vSphere host using vconnector-cli:

.. code-block:: bash

$ vconnector-cli -H vc01.example.org enable

Here this is how to disable a vSphere host:

.. code-block:: bash

$ vconnector-cli -H vc01.example.org disable

And here is how to get the currently registered vSphere hosts from
the vConnector database:

.. code-block:: bash

$ vconnector-cli get
+---------------------------+---------------------+--------------+-----------+
| Hostname | Username | Password | Enabled |
+===========================+=====================+==============+===========+
| vc01.example.org | root | p4ssw0rd | 0 |
+---------------------------+---------------------+--------------+-----------+

Using the vConnector API
========================

Here are a few examples of using the ``vconnector`` module API.

Connecting to a vSphere host:

.. code-block:: python

>>> from vconnector.core import VConnector
>>> client = VConnector(
... user='root',
... pwd='p4ssw0rd',
... host='vc01.example.org'
...)
>>> client.connect()

Disconnecting from a vSphere host:

.. code-block:: python

>>> client.disconnect()

Re-connecting to a vSphere host:

.. code-block:: python

>>> client.reconnect()

How to get a ``VMware vSphere View`` of all ``VirtualMachine``
managed objects:

.. code-block:: python

>>> from vconnector.core import VConnector
>>> client = VConnector(
... user='root',
... pwd='p4ssw0rd',
... host='vc01.example.org'
...)
>>> client.connect()
>>> vms = client.get_vm_view()
>>> print vms.view
(ManagedObject) [
'vim.VirtualMachine:vm-36',
'vim.VirtualMachine:vm-129',
'vim.VirtualMachine:vm-162',
'vim.VirtualMachine:vm-146',
'vim.VirtualMachine:vm-67',
'vim.VirtualMachine:vm-147',
'vim.VirtualMachine:vm-134',
'vim.VirtualMachine:vm-88'
]
>>> client.disconnect()

How to get a ``Managed Object`` by a specific property, e.g. find the
Managed Object of an ESXi host which name is ``esxi01.example.org``:

.. code-block:: python

>>> import pyVmomi
>>> from vconnector.core import VConnector
>>> client = VConnector(
... user='root',
... pwd='p4ssw0rd',
... host='vc01.example.org'
... )
>>> client.connect()
>>> host = client.get_object_by_property(
... property_name='name',
... property_value='esxi01.example.org',
... obj_type=pyVmomi.vim.HostSystem
... )
>>> print host.name
'esxi01.example.org'
>>> client.disconnect()

How to collect properties for ``vSphere Managed Objects``, e.g. get
the ``name`` and ``capacity`` properties for all ``Datastore``
managed objects:

.. code-block:: python

>>> import pyVmomi
>>> from vconnector.core import VConnector
>>> client = VConnector(
... user='root',
... pwd='p4ssw0rd',
... host='vc01.example.org'
... )
>>> client.connect()
>>> datastores = client.get_datastore_view()
>>> result = client.collect_properties(
... view_ref=datastores,
... obj_type=pyVmomi.vim.Datastore,
... path_set=['name', 'summary.capacity']
...)
>>> print result
[{u'summary.capacity': 994821799936L, u'name': 'datastore1'}]
>>> client.disconnect()
