Python Module for TrueNAS Websocket API

This python module utilizes the TrueNAS Websocket API to get state from a TrueNAS instance.

Installation

pip install aiotruenas-client

Usage

from aiotruenas_client import CachingMachine as TrueNASMachine

machine = await TrueNASMachine.create(
    "hostname.of.machine",
    api_key="someapikey"
)
datasets = await machine.get_datasets()
disks = await machine.get_disks()
jails = await machine.get_jails()
pools = await machine.get_pools()
vms = await machine.get_vms()

Alternatively, a username and password may also be supplied.

Machine

Object representing a TrueNAS instance.

Dataset

Available from machine.datasets, contains information about the datasets on the pools on the machine.

Disk

Available from machine.disks, contains information about the disks attached to the machine.

Jail

Available from machine.jails, contains information about the jails available on the machine.

Pool

Available from machine.pools, contains information about the ZFS pools known to the machine.

VirturalMachine

Available from machine.vms, contains information about the virtural machines available on the machine.

Each instance has the following methods availabe:

• vm.start
• vm.stop
• vm.restart

Development

# One-Time Install of Commit Hooks
pre-commit install

Working With Methods & Subscriptions

When adding support for a new object, or updating existing code, it can be useful to see the raw response from the TrueNAS machine from time to time. In order to help do that easily, you can drop a .auth.yaml file in the root of the repository, with the following content:

host: "some.host.name"
api_key: "someapikey"

Use scripts/invoke_method.py to call a method:

python scripts/invoke_method.py disk.query

Use scripts/subscribe.py to subscribe to a topic:

python scripts/subscribe.py reporting.realtime

Run either with -h to see additional options.

Testing

Tests are run with pytest.
