S3Trigger

class aws_cdk.aws_codepipeline_actions.S3Trigger(value)

Bases: Enum

How should the S3 Action detect changes.

This is the type of the S3SourceAction.trigger property.

ExampleMetadata:: infused

Example:

import aws_cdk.aws_cloudtrail as cloudtrail

# source_bucket: s3.Bucket

source_output = codepipeline.Artifact()
key = "some/key.zip"
trail = cloudtrail.Trail(self, "CloudTrail")
trail.add_s3_event_selector([cloudtrail.S3EventSelector(
    bucket=source_bucket,
    object_prefix=key
)],
    read_write_type=cloudtrail.ReadWriteType.WRITE_ONLY
)
source_action = codepipeline_actions.S3SourceAction(
    action_name="S3Source",
    bucket_key=key,
    bucket=source_bucket,
    output=source_output,
    trigger=codepipeline_actions.S3Trigger.EVENTS
)

Attributes

EVENTS

CodePipeline will use CloudWatch Events to be notified of changes.

Note that the Bucket that the Action uses needs to be part of a CloudTrail Trail for the events to be delivered.

NONE: The Action will never detect changes - the Pipeline it’s part of will only begin a run when explicitly started.

POLL

CodePipeline will poll S3 to detect changes.

This is the default method of detecting changes.
