-All Amazon ECR API actions are logged by CloudTrail and are documented in the [Amazon Elastic Container Registry API Reference](https://docs.aws.amazon.com/AmazonECR/latest/APIReference/). When you perform common tasks, sections are generated in the CloudTrail log files for each API action that is part of that task. For example, when you create a repository, `GetAuthorizationToken`, `CreateRepository` and `SetRepositoryPolicy` sections are generated in the CloudTrail log files. When you push an image to a repository, `InitiateLayerUpload`, `UploadLayerPart`, `CompleteLayerUpload`, and `PutImage` sections are generated. When you pull an image, `GetDownloadUrlForLayer` and `BatchGetImage` sections are generated. When you archive or restore an image `UpdateImageStorageClass` section is generated. When OCI clients that support the OCI 1.1 specification fetch the list of referrers, or reference artifacts, for an image using the Referrers API, a `ListImageReferrers` CloudTrail event is emitted. For examples of these common tasks, see CloudTrail log entry examples.
