Installation

Install PySphere:

pip install -U pysphere

Edit the script's login data and VCenter server FQDN:

server_fqdn = "vcenter.example.org"server_username = "jdoe"server_password = "secure_passw0rd"

Test it:

Get all powered on VM's:

python2 query.py --list

Output:

{    "no_group": {        "hosts": [            "vm0031",            "vm0032",            [...]            "vm0999"        ]    },    "local": [        "127.0.0.1"    ]}

Get one VM:

python2 query.py --host vm0032

Output:

{    "admin": "sysadmin@example.org",    "source_database": "VMWare"}

Nonexistent VM:

python2 query.py --host nonexist

Output:

[Error]: [Object Not Found]: Could not find a VM named 'notexist'

Do a simple ansible ping:

ANSIBLE_HOSTS="/home/remy/git/vmware-ansible/query.py" ansible all -m ping

Result:

vm0032 | success >> {    "changed": false,    "ping": "pong"}vm0034 | success >> {    "changed": false,    "ping": "pong"}

Usage

Either export the ANSIBLE_HOSTS variable to always use the VMWare inventory:

export ANSIBLE_HOSTS="/home/remy/git/vmware-ansible/query.py"

Or preface each ansible command:

ANSIBLE_HOSTS="/home/remy/git/vmware-ansible/query.py" ansible all -m apt -a "upgrade=safe"

Notes

Tested with both vCenter 5.1 and 5.5, Python 2.

Does not support grouping by datacenter or resource group
