Python client for the EIS Virtual Cloud RESTful API
The python client allows you to interact with the API using self-descriptive methods.

Install
Installing the library is quite simple. Either clone the GitLab repository or download the source code or use pip to do everything for you:
Code Block |
---|
# pip virtualenv ~/VirtualEnvs/pyvss . ~/VirtualEnvs/pyvss/activate pip install pyvss # git git clone git@gitlabhttps://gitlab.eis.utoronto.ca:/vss/py-vss.git cd py-vss python setup.py install |
Docker
If you prefer running your scripts in a docker container, the uofteis/pyvss image is the solution. It's based on Alpine Linux with Python 2.7.12 and works as follows:
Code Block |
---|
# with access token docker run -it -v .:/data -e VSS_API_TOKEN=token_here uofteis/pyvss # user and pass docker run -it -v .:/data -e VSS_API_USER=user_here -e VSS_API_USER_PASS=user_pass_here uofteis/pyvss # env file containing either VSS_API_USER and VSS_API_USER_PASS or VSS_API_TOKEN docker run -it -v .:/data --env-file vss.env uofteis/pyvss |
Usage
Creating a virtual machine is as easy as calling the create_vm method as follows:
Code Block | ||
---|---|---|
| ||
from pyvss.manager import VssManager vss = VssManager(tk='api_token') # get vms vms = vss.get_vms() # 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') |
By setting the VSS_API_TOKEN environment variable and then executing the manager.py script and using as input args the function name followed by any parameters, the response is displayed to stdout.
