pip install cloudshell-pdu-core

Common errors

error ModuleNotFoundError: No module named 'cloudshell_pdu_core' ↓

cause Importing with underscores instead of dots.

fix

Use: from cloudshell.pdu.core.driver import PDUResourceDriver

error TypeError: Can't instantiate abstract class PDUResourceDriver with abstract methods ... ↓

cause Trying to instantiate PDUResourceDriver directly without implementing required methods.

fix

Subclass PDUResourceDriver and implement all abstract methods from PowerControlInterface.

Warnings

gotcha Import paths use 'cloudshell.pdu.core' (dots), not underscores. Wrong imports from underscores will fail. ↓

fix Use 'from cloudshell.pdu.core.driver import PDUResourceDriver'

deprecated Python 3.7 and lower are no longer supported; requires Python >= 3.8. ↓

fix Upgrade to Python 3.8+

gotcha The package is a utility library, not a standalone driver. Direct instantiation of PDUResourceDriver without a concrete implementation will raise errors. ↓

fix Subclass PDUResourceDriver and implement abstract methods.

Imports

PDUResourceDriver

wrong

from cloudshell_pdu_core.driver import PDUResourceDriver

correct

from cloudshell.pdu.core.driver import PDUResourceDriver

Use dot notation (cloudshell.pdu.core) not underscores.

PowerControlInterface

from cloudshell.pdu.core.interfaces import PowerControlInterface

Quickstart

Minimal example of subclassing PDUResourceDriver.

from cloudshell.pdu.core.driver import PDUResourceDriver
from cloudshell.pdu.core.interfaces import PowerControlInterface

class MyPDUDriver(PDUResourceDriver):
    def __init__(self):
        super().__init__()
        # No authentication required for this example

driver = MyPDUDriver()
print("PDU driver initialized successfully.")
