Pre-Requisites

Setup a Notification Channel Integrationon the Integrations page. Please follow this document to add an integration.

Currently two types of Notification Channels are supported:

  1. Slack (Webhook URL based): For this, please create a webhook for your slack and then add it as an integration in Slack Provider Account (Slack Webhook Integration)
  2. Slack (Bot Token based): For this, please create a bot token for your slack and then add it as an integration in Slack Provider Account (Slack Bot Integration). It requires chat:write and chat:write:public scope. You can add slack channels to send to respective slack channel.
  3. Email (SMTP credentials Integration): This can be found in Custom Provider Account. You can configure the SMTP Credentials of the mail server, from_email and to_emails and use it to send notifications.

How to Configure

​
Define alerts in workflow Decorator

  • You can define or configure the alerts in the workflow decorator in your workflow file.
from truefoundry.workflow import ...
from truefoundry.deploy import Resources, WorkflowAlert, Email, SlackWebhook

...
...
@workflow(
    alerts=[
        WorkflowAlert(
            notification_target=Email(
                notification_channel="<Paste your email notification integration fqn here>",
                to_emails=[
                    "demo@truefoundry.com"
                ],
            ),
            on_completion=True,
            on_failure=True,
        ),
        WorkflowAlert(
            notification_target=SlackWebhook(
                notification_channel="<Paste your slack webhook notification integration fqn here>",
            ),
            on_completion=True,
            on_failure=True,
        ),
        WorkflowAlert(
            notification_target=SlackBot(
                notification_channel="<Paste your slack bot notification integration fqn here>",
                channels:[
                    "#workflow-notifications"
                ]
            ),
            on_completion=True,
            on_failure=True,
        ),
    ]
)
def my_workflow():
	...

​
⚠️Make sure that the truefoundry package version is set to latest version in task config.

For example in pip_packages filed in python task config, make sure that trufoundry[workflow] version is 0.6.3 or newer and not older one, or make sure that version which you are mentioning supports alerts.

  • Right now the alert notification is supported only for workflow completion(successful completio and workflow failure(failure includes failed executions and aborted as well as timed out workflow executions).
  • There are three types of targets, one is email and the others are slack webhook and slack bot, you need to add an email/slack webhook/slack bot integration respectively and select it in notification channel field to use that integration for sending notifications.
  • Now when you will deploy the workflow, the alerts will be set.

​
Define alerts in deploy.py file

  • Another way to define alerts is to define workflow in deploy.py file and set alerts in it.
from truefoundry.deploy import Workflow, WorkflowAlert, SlackWebhook, Email


wf = Workflow(
    name="test-email-alerts-2",
    workflow_file_path="nested.py",
    alerts=[
        WorkflowAlert(
            notification_target=SlackWebhook(
                notification_channel="<Paste your slack webhook notification integration fqn here>",
            ),
            on_completion=True,
            on_failure=True,
        ),
        WorkflowAlert(
            notification_target=Email(
                notification_channel="<Paste your email notification integration fqn here>",
                to_emails=["demo@truefoundry.com"],
            ),
            on_completion=True,
            on_failure=True,
        ),
        WorkflowAlert(
            notification_target=SlackBot(
                notification_channel="<Paste your slack bot notification integration fqn here>",
                channels=["#workflow-notifications"],
            ),
            on_completion=True,
            on_failure=True,
        ),
    ],
)

wf.deploy("<workspace-fqn>", wait=False)
  • After defining this, you can just run python deploy.py and your workflow will be deployed and alerts will be set.
