class airflow.providers.papermill.hooks.kernel.KernelHook(kernel_conn_id=default_conn_name, *args, **kwargs)[source]¶

Bases: airflow.hooks.base.BaseHook

The KernelHook can be used to interact with remote jupyter kernel.

Takes kernel host/ip from connection and refers to jupyter kernel ports and session_key: from extra field.

Parameters: kernel_conn_id (str) – connection that has kernel host/ip

conn_name_attr = 'kernel_conn_id'[source]¶

default_conn_name = 'jupyter_kernel_default'[source]¶

conn_type = 'jupyter_kernel'[source]¶

hook_name = 'Jupyter Kernel'[source]¶

get_conn()[source]¶

Return connection for the hook.

airflow.providers.papermill.hooks.kernel.register_remote_kernel_engine()[source]¶: Register RemoteKernelEngine papermill engine.

class airflow.providers.papermill.hooks.kernel.RemoteKernelManager(*args, **kwargs)[source]¶

Bases: jupyter_client.AsyncKernelManager

Jupyter kernel manager that connects to a remote kernel.

property has_kernel: bool[source]¶

Has a kernel process been started that we are actively managing.

session_key[source]¶

shutdown_kernel(now=False, restart=False)[source]¶

client(**kwargs)[source]¶

Create a client configured to connect to our kernel.

class airflow.providers.papermill.hooks.kernel.RemoteKernelEngine[source]¶

Bases: papermill.engines.NBClientEngine

Papermill engine to use RemoteKernelManager to connect to remote kernel and execute notebook.

classmethod execute_managed_notebook(nb_man, kernel_name, log_output=False, stdout_file=None, stderr_file=None, start_timeout=60, execution_timeout=None, **kwargs)[source]¶: Perform the actual execution of the parameterized notebook locally.
