Events placeholder bucket reference
This section is a reference only. For information about creating a pipeline with event detection resources, see Source actions and change detection methods.
Source actions provided by Amazon S3 and CodeCommit use event-based change detection resources to trigger your pipeline when a change is made in the source bucket or repository. These resources are the CloudWatch Events rules that are configured to respond to events in the pipeline source, such as a code change to the CodeCommit repository. When you use CloudWatch Events for an Amazon S3 source, you must turn on CloudTrail so the events are logged. CloudTrail requires an S3 bucket where it can send its digests. You can access the log files for your CloudWatch Events resources from the custom bucket, but you cannot access the data from the placeholder bucket.
-
If you used the CLI or AWS CloudFormation to set up the CloudWatch Events resources, you can find your CloudTrail files in the bucket that you specified when you set up your pipeline.
-
If you used the console to set up your pipeline with an S3 source, the console uses a CloudTrail placeholder bucket when it creates your CloudWatch Events resources for you. CloudTrail digests are stored in the placeholder bucket in the AWS Region where the pipeline is created.
You can change the configuration if you want to use a bucket other than the placeholder bucket.
Note
Data written to CloudTrail placeholder buckets automatically expires after one day and is not retained.
For more information about finding and managing your CloudTrail log files, see Getting and Viewing Your CloudTrail Log Files.
