Odoo Workflow Orchestration Engine

Workflow Orchestration Engine is a centralized orchestration server for running tasks from several different task runner client components.

Components

Tasks: Definition of a job that needs to be accomplished and managed Workflow: Set of tasks and rules that implement a certain chain of execution Workflow Orchestration Server: Centralized management of all workflow definition as well as all workflow execution. Task Runner Client: Component responsible for the asynchronous execution of the tasks defined in one or several orchestration engines.

                 |     |                     |      |
                 |     |                     |      |
Task             |     |   Task              |      |     Task
Runner 1  <------+     +-> Runner 2   <------+      +-->  Runner 3

It's always the responsibility of the Task Runner to communicate with the Orchestration server(OCS). OCS will implement processes to monitor the workitems but it will avoid to interfere with the execution of the Tasks.

Install

./odoo/odoo-bin shell -d database -i

Requirements

• Python 2.7
• Odoo - 10.0

Running a Workflow

Create a test file:

test-1.py:

#!/bin/python
# Workflow has a start parametes json
values = """
{
    "project_id": 189,
    "name": "This is a test task",
    "uid": 1
}
"""
env['work.workflow'].search([('id', '=', 1)]).run_workflow(values, debug=True)

env.cr.commit()

Use the test file to start the workflow:

$> ./odoo/odoo-bin shell -d database < test-1.py
