S3 Bucket Event Lambda Trigger
Note: The information in this section is applicable for an app executable only.
Use the S3 Bucket Event Lambda trigger to trigger a Lambda function when a supported event occurs on the associated S3 bucket.
Trigger Settings
Note:
- Creating a new event or updating an existing event in the S3 Bucket Event Lambda trigger and re-pushing the app deletes existing Events on AWS S3.
- You can have only one S3 trigger in an app. An app that has an S3 trigger cannot contain any other triggers including another S3 trigger. The S3 trigger supports multiple handlers (flows), so you can have multiple flows in the app that are attached to the same S3 trigger. You can also have blank flows in the app which can serve as subflows for the flows that are attached to the S3 trigger.
For overriding app properties, use the FLOGO_APP_PROPS_JSON environment variable only. You cannot override app properties using the FLOGO_APP_PROPS_ENV environment variable.
