Documentation

Package documentation is now available at docs.

Installation

The fastest way to install PyVSS is to use pip:

pip install pyvss

To interact with vskey-stor, install pyvss with extras:

pip install pyvss[stor]

If you have PyVSS installed and want to upgrade to the latest version you can run:

pip install --upgrade pyvss

This will install PyVSS as well as all dependencies.

You can also just download the tarball. Once you have the py-vss directory structure on your workstation, you can just run:

cd <path_to_py-vss>
pip install .

macOS

You can use pip directly to install PyVSS. Run pip --version to see if your version of macOS already includes Python and pip.

pip --version

If you don't have pip installed, first download and install Python 3.7 for Mac from the downloads page of Python.org. Download and run the pip installation script provided by the Python Packaging Authority.

   curl -O https://bootstrap.pypa.io/get-pip.py
   python3 get-pip.py --user

1. Use pip to install PyVSS.

pip install pyvss --upgrade --user

1. Verify that the PyVSS is installed correctly.

pip freeze | grep pyvss

Linux

You can use pip directly to install PyVSS. Run pip --version to see if your version of Linux already includes Python and pip.

   pip --version

If you don't have pip installed, first download and install Python 3.5 for Linux from the downloads page of Python.org or using your preferred package manager. Download and run the pip installation script provided by the Python Packaging Authority.

   curl -O https://bootstrap.pypa.io/get-pip.py
   python3 get-pip.py --user

1. Use pip to install PyVSS.

pip install pyvss --upgrade --user

1. Verify that the PyVSS is installed correctly.

pip freeze | grep pyvss

Windows

1. Open the Command Prompt from the Start menu.

2. Use the following commands to verify that Python and pip are both installed correctly.

C:\Windows\System32> python --version
Python 3.7.1
C:\Windows\System32> pip --version
pip 18.1 from c:\program files\python37\lib\site-packages\pip (python 3.7)

1. Install PyVSS CLI using pip.

C:\Windows\System32> pip install pyvss

1. Verify that PyVSS is installed correctly.

C:\Windows\System32> pip freeze | findstr pyvss

Docker

Use

Create an instance of VssManager passing your ITS Private Cloud API access token and your are all set to start calling any of the self-descriptive methods included:

from pyvss.manager import VssManager
vss = VssManager(tk='api_token')
# list vms
vms = vss.get_vms()
# list folders
folders = vss.get_folders()
# networks
networks = vss.get_networks()
# domains
domains = vss.get_domains()
# power cycle vm
vss.power_cycle_vm(uuid='<uuid>')  
# create vm
req = vss.create_vm(os='ubuntu64Guest', built='os_install',
                    description='Testing python wrapper',
                    folder='group-v6736', bill_dept='EIS', disks=[100, 100])
uuid = vss.wait_for_request(req['_links']['request'], 'vm_uuid', 'Processed')
# creating multiple vms
reqs = vss.create_vms(count=3, name='python', os='ubuntu64Guest', bill_dept='EIS',
        description='Testing multiple deployment from python wrapper',
        folder='group-v6736', built='os_install')
uuids = [vss.wait_for_request(r['_links']['request'], 'vm_uuid', 'Processed') for r in reqs]
# power on recently created vms
for uuid in uuids:
   vss.power_on_vm(uuid)    
# create snapshot
req = vss.create_vm_snapshot(uuid='5012abcb-a9f3-e112-c1ea-de2fa9dab90a',
                             desc='Snapshot description',
                             date_time='2016-08-04 15:30',
                             valid=1)
snap_id = vss.wait_for_request(req['_links']['request'], 'snap_id', 'Processed')
# revert to snapshot
req = vss.revert_vm_snapshot(uuid, snap_id)

An alternative is to generate a token from within the VssManager class and this can be done by setting the following environment variables

export VSS_API_USER='username'
export VSS_API_USER_PASS='username_password'

Then, from the VssManager call the get_token method as follows:

from pyvss.manager import VssManager
vss = VssManager()
vss.get_token()
