Abstract

This document describes the vSphere Automation Python SDK samples that use the vSphere Automation python client library. Additionally, some of the samples demonstrate the combined use of the vSphere Automation and vSphere APIs. To support this combined use, the vSphere Automation Python SDK samples require the vSphere Management SDK packages (pyVmomi) to be installed on the client. The samples have been developed to work with python 2.7.x and 3.3+

Supported vCenter Releases

vCenter 6.0 and 6.5. Certain APIs and samples that are introduced in 6.5 release, such as vCenter, Virtual Machine and Appliance Management. Please refer to the notes in each sample for detailed compatibility information.

VMware Cloud on AWS Support

The VMware Cloud on AWS API and samples are currently available as a preview and are subject to change in the future.

Quick Start Guide

Prepare a Python Development Environment

We recommend you to install latest Python and pip on your system.

A Python virtual environment is also highly recommended.

• Install a virtual env for Python 2
• Install a virtual env for Python 3

Installing Required Python Packages

git clone https://github.com/vmware/vsphere-automation-sdk-python.git
cd vsphere-automation-sdk-python
pip install --upgrade --force-reinstall -r requirements.txt --extra-index-url file:///`pwd`/lib

NOTE: The SDK also requires OpenSSL 1.0.1+ if you want to connect to vSphere 6.5+ in order to support TLS1.1 & 1.2

Connect to a vCenter Server

import requests
import urllib3
from vmware.vapi.vsphere.client import create_vsphere_client
session = requests.session()

# Disable cert verification for demo purpose. 
# This is not recommended in a production environment.
session.verify = False

# Disable the secure connection warning for demo purpose.
# This is not recommended in a production environment.
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

# Connect to a vCenter Server using username and password
vsphere_client = create_vsphere_client(server='<vc_ip>', username='<vc_username>', password='<vc_password>', session=session)

# List all VMs inside the vCenter Server
vsphere_client.vcenter.VM.list()

Run SDK Samples

In this section we will walk you through the steps to run the sample code for vSphere and VMware Cloud on AWS APIs.

First, set PYTHONPATH to use SDK helper methods

• Linux/Mac:

  export PYTHONPATH=${PWD}:$PYTHONPATH

• Windows:

  set PYTHONPATH=%cd%;%PYTHONPATH%

Run VMware Cloud on AWS Samples

$ python samples/vmc/orgs/organization_operations.py -r <refresh_token>

Run vSphere Samples

A vSphere test environment is required with the following configuration:

• 1 vCenter Server
• 2 ESX hosts
• 1 NFS Datastore with at least 3GB of free capacity

Note Please have the details of these available but do not have any configuration pre-created on vCenter server or ESXi Hosts, for example there should be no existing datacenters, clusters or attached hosts on the vCenter server.

Running the SDK Sample Setup Script

Before executing the samples we'll need to setup the vSphere test environment using one of the sample scripts (samples/vsphere/vcenter/setup/main.py). The script will perform the following:

• Create 2 test Datacenters
• Create a test Cluster
• Create Test Folders for VM Storage
• Attach the hosts
• Create a Distributed Switch
• Create a Distributed Portgroup
• Attach the NFS datastore (if Selected) to the hosts
• Copy the Photon OS ISO image downloaded from VMware's bintray server to the datastore
• Create directories to add sample ports

First, edit settings in samples/vsphere/vcenter/setup/testbed.py and replace everything in < > brackets with your environment information. Leave the rest of the settings in this file at their default values.

config["SERVER"]    = "<vcenter_hostname_or_ip>"
config["USERNAME"]  = "<vsphere_username>"
config["PASSWORD"]  = "<vsphere_password>"

config["ESX_HOST1"] = "<ESX_host1_ipaddress>"
config["ESX_HOST2"] = "<ESX_host2_ipaddress>"
config["ESX_USER"]  = "<esx_username>"
config["ESX_PASS"]  = "<esx_password>"

config["USE_NFS"]   = True
config["NFS_HOST"]  = "<nfs_ipaddress>"
config["NFS_REMOTE_PATH"] = "/store1"

At this point, we're ready to run the setup script:

$ python samples/vsphere/vcenter/setup/main.py -sv

After completion you will see from the output and also the vSphere Client that the environment has now been fully setup and is ready to easily run further samples.

To view other available command-line options:

$ python samples/vsphere/vcenter/setup/main.py -h

Run the vAPI vCenter sample suite:

$ python samples/vsphere/vcenter/setup/main.py -riv

Run a specific sample in a standalone mode:

$ python samples/vsphere/vcenter/vm/list_vms.py -v

Resource Maintenance

Maintenance Ownership

Ownership of any and all submitted samples are maintained by the submitter.

Filing Issues

Any bugs or other issues should be filed within GitHub by way of the repository’s Issue Tracker.

Resolving Issues

Any community member can resolve issues within the repository, however only the board member can approve the update. Once approved, assuming the resolution involves a pull request, only a board member will be able to merge and close the request.

VMware Sample Exchange

It is highly recommended to add any and all submitted samples to the VMware Sample Exchange: https://code.vmware.com/samples

Sample Exchange can be allowed to access your GitHub resources, by way of a linking process, where they can be indexed and searched by the community. There are VMware social media accounts which will advertise resources posted to the site and there's no additional accounts needed, as the VMware Sample Exchange uses MyVMware credentials.
