Netflix Conductor SDK - Python

The conductor-python repository provides the client SDKs to build task workers in Python.

Building the task workers in Python mainly consists of the following steps:

1. Setup conductor-python package
2. Create and run task workers
3. Create workflows using code

Setup Conductor Python Package​

• Create a virtual environment to build your package

virtualenv conductor
source conductor/bin/activate

• Get Conductor Python SDK

python3 -m pip install conductor-python

Server Settings

Everything related to server settings should be done within the Configuration class by setting the required parameter (when initializing an object) like this:

configuration = Configuration(
    server_api_url='https://play.orkes.io/api',
    debug=True
)

• server_api_url : Conductor server address. For example, if you are running locally, it would look like; http://localhost:8000/api.
• debug: It can take the values true/false. true for verbose logging false to display only the errors

Authentication Settings (Optional)

Configure the authentication settings if your Conductor server requires authentication.

Access Control Setup

See Access Control for more details on role-based access control with Conductor and generating API keys for your environment.

configuration = Configuration(
    authentication_settings=AuthenticationSettings(
        key_id='key',
        key_secret='secret'
    )
)

Metrics Settings (Optional)

Conductor uses Prometheus to collect metrics.

metrics_settings = MetricsSettings(
    directory='/path/to/folder',
    file_name='metrics_file_name.extension',
    update_interval=0.1,
)

• directory: Directory to store the metrics.
  • Ensure that you have already created this folder, or the program should have permission to create it for you.
• file_name: File where the metrics are stored.
  • example: metrics.log
• update_interval: Time interval in seconds to refresh metrics into the file.
  • example: 0.1 means metrics are updated every 0.1s or 100ms.

Create and Run Task Workers

The next step is to create and run task workers.

Create Workflows using Code

Finally, you can create workflows using code.
