Job event Slack notifications with Lambda and EventBridge

The job_events_slack_lambda CloudFormation template on the GitHub website sends a Slack notification whenever a job completes (SUCCEEDED) or fails (FAILED). Use it as a starting point for connecting a Lambda function to Deadline Cloud job events through EventBridge. You can adapt the function to send an email, open a ticket, update a dashboard, or trigger a downstream workflow.

The template creates the following resources:

• A Lambda function is defined inline in the template using only the Python standard library. It formats the job event and posts it to a Slack Incoming Webhook URL stored in its SLACK_WEBHOOK_URL environment variable.

• An EventBridge rule matches Job Run Status Change events with a taskRunStatus of SUCCEEDED or FAILED, and invokes the function. You can scope the rule to a single farm.

• An execution role grants the function only CloudWatch Logs write access. A permission allows EventBridge to invoke the function.

Many messaging apps expose the same style of incoming webhook. To target Microsoft Teams, Discord, Google Chat, or Mattermost instead, set that app's webhook URL and adjust the JSON body the function builds; the README links each app's webhook documentation.
