Python Operations

The Python module allows you to execute Python code within the context of a deploy.

python.call

Stateless operation

This operation will always execute commands and is not idempotent.

Execute a Python function within a deploy.

python.call(function: Callable, **kwargs)

function**: the function to execute args**: arguments to pass to the function kwargs**: keyword arguments to pass to the function

ample:**

ode:: python

def my_callback(hello=None):

command = ‘echo hello’ if hello:

command = command + ‘ ‘ + hello

status, stdout, stderr = host.run_shell_command(command=command, sudo=SUDO) assert status is True # ensure the command executed OK

if ‘hello ‘ not in ‘n’.join(stdout): # stdout/stderr is a list of lines

raise Exception(

f’{command} problem with callback stdout:{stdout} stderr:{stderr}’,

)

python.call(

name=”Run my_callback function”, function=my_callback, hello=”world”,

) Note:

This operation also inherits all global arguments.

python.raise_exception

Stateless operation

This operation will always execute commands and is not idempotent.

Raise a Python exception within a deploy.

python.raise_exception(exception: Exception, **kwargs)

exception**: the exception class to raise args**: arguments passed to the exception creation kwargs**: keyword arguments passed to the exception creation

ample**:

ode:: python

python.raise_exception(

name=”Raise NotImplementedError exception”, exception=NotImplementedError, message=”This is not implemented”,

) Note:

This operation also inherits all global arguments.
