armonik 3.22.0

GRPC python binding for the ArmoniK orchestrator API

ArmoniK.Api Python package

This folder contains the necessary scripts to generate the ArmoniK.Api Python package. Please note that while the package generation is platform dependent, the generated package should be compatible with Linux and Windows.

Install the Python Package from PyPI

At each release, we provide a prepackaged version of ArmoniK.Api available on PyPI here : https://pypi.org/project/armonik. To install the package to your current Python environment, you can use pip :

pip install armonik

Linux / WSL

How to generate

Requirements :

• Python >= 3.7
• Python3-venv
• Pip3
• Bash

If the python command doesn't link to python3 on your system, you may be able to install the package python-is-python3, which links python to python3.

To generate the package from sources, run the proto2python.sh script from its folder. You need to specify a directory where the virtual environment used for the build will be located. For example the following command will generate the packages and will create the build environment "pyvenv" in the current user's home directory:

./proto2python.sh ~/pyvenv

3 folders will be created :

• generated : contains the source files used to create the package
• build : contains the source files used to create the wheel package
• pkg : contains the sdist and wheel packages

Instead of running the script you can install the armonik package in "editable" mode, allowing you to make changes to the source code, and the changes will be reflected immediately without reinstalling the package.

pip install -e ./packages/python

How to install the generated package

From this directory, use the following command:

pip install pkg/armonik*.whl

The generated package will be installed to your current python environment

Windows

Coming soon

Tests

Test Environment Setup

Before running tests, ensure the following setup steps are completed:

1. Install Dependencies:

sudo apt install dotnet-sdk-6.0 jq

2. Launch the Mock Server:

Verify that port 5000 is available (Armonik and the mock server communicate on the same port, uninstall armonik if necessary):

lsof -i :5000

3. Launch the server from the project's root directory in a separate terminal:

cd packages/csharp/ArmoniK.Api.Mock
dotnet run

Test Environment Summary

The test environment utilizes a mock endpoint to assert if the ArmoniK service has been triggered. It leverages the requests library to query the /calls.json endpoint, examining the JSON response to validate the count of remote procedure calls made to specific services and methods

curl localhost:5000/calls.json | jq

In prevision of the API test, run the following command:

curl localhost:5000/calls.json | jq '.Tasks'

You should have as output:

{
  "GetTask": 0,
  "ListTasks": 0,
  "GetResultIds": 0,
  "CancelTasks": 0,
  "CountTasksByStatus": 0,
  "ListTasksDetailed": 0,
  "SubmitTasks": 0
}

Configure gRPC channel and test API calls

Once the endpoint runs, you can initiate a gRPC channel to it with a Python client.

Below is an example using a Tasks client and calling the list_tasks method:

import grpc
import armonik.client
with grpc.insecure_channel("localhost:5001") as channel:
    tasks_client = ArmoniKTasks(channel)
    tasks.client.list_tasks()

Port 5001 is actually ArmoniK's control-plane endpoint.

For the sake of simplicity, the example gRPC channel here is an insecure one. You should never do that in production environment.

Check if API call was successful

Execute the Python code snippet above and re-run command:

curl localhost:5000/calls.json | jq '.Tasks'

You should have as output:

{
  "GetTask": 0,
  "ListTasks": 0,
  "GetResultIds": 0,
  "CancelTasks": 0,
  "CountTasksByStatus": 0,
  "ListTasksDetailed": 1,
  "SubmitTasks": 0
}

You can see that attribute ListTasksDetailed was incremented, meaning that the API effectively handled your call !

WARNING

Note for Users

Starting from gRPC version 1.57 and onward, it is necessary to explicitly specify the default authority when creating the gRPC channel. more details
