class jina.orchestrate.pods.BasePod(args)[source]#

Bases: ABC

BasePod is an interface from which all the classes managing the lifetime of a Runtime inside a local process, container must inherit.

It exposes the required APIs so that the BasePod can be handled by the cli api as a context manager or by a Deployment.

What makes a BasePod a BasePod is that it manages the lifecycle of a Runtime (gateway or not gateway)

close()[source]#

Close the Pod

This method makes sure that the Process is properly finished and its resources properly released

Return type:: None

wait_start_success()[source]#

Block until all pods starts successfully.

If not success, it will raise an error hoping the outer function to catch it

async async_wait_start_success()[source]#: Wait for the Pod to start successfully in a non-blocking manner

property role: PodRoleType#

Get the role of this pod in a deployment .. #noqa: DAR201

Return type:: PodRoleType

abstract start()[source]#: Start the BasePod. This method calls start() in multiprocesssing.Process. .. #noqa: DAR201

abstract join(*args, **kwargs)[source]#

Joins the BasePod. Wait for the BasePod to properly terminate

Parameters:

args – extra positional arguments
kwargs – extra keyword arguments

class jina.orchestrate.pods.Pod(args)[source]#

Bases: BasePod

Pod is a thread/process- container of BaseRuntime. It leverages multiprocessing.Process to manage the lifecycle of a BaseRuntime object in a robust way.

A Pod must be equipped with a proper Runtime class to work.

start()[source]#: Start the Pod. This method calls start() in multiprocesssing.Process. .. #noqa: DAR201

join(*args, **kwargs)[source]#

Joins the Pod. This method calls join() in multiprocesssing.Process.
