Logging Amazon ECR API Calls with AWS CloudTrail

Amazon ECR is integrated with AWS CloudTrail, a service that provides a record of actions taken by a user, role, or an AWS service in Amazon ECR. CloudTrail captures all API calls for Amazon ECR as events, including calls from the Amazon ECR console and from code calls to the Amazon ECR APIs. If you create a trail, you can enable continuous delivery of CloudTrail events to an Amazon S3 bucket, including events for Amazon ECR. If you don't configure a trail, you can still view the most recent events in the CloudTrail console in Event history. Using this information, you can determine the request that was made to Amazon ECR, the originating IP address, who made the request, when it was made, and additional details.

For more information, see the AWS CloudTrail User Guide.

Amazon ECR Information in CloudTrail

CloudTrail is enabled on your AWS account when you create the account. When activity occurs in Amazon ECR, that activity is recorded in a CloudTrail event along with other AWS service events in Event history. You can view, search, and download recent events in your AWS account. For more information, see Viewing Events with CloudTrail Event History.

For an ongoing record of events in your AWS account, including events for Amazon ECR, create a trail. A trail enables CloudTrail to deliver log files to an Amazon S3 bucket. By default, when you create a trail in the console, the trail applies to all regions. The trail logs events from all regions in the AWS partition and delivers the log files to the Amazon S3 bucket that you specify. Additionally, you can configure other AWS services to further analyze and act upon the event data collected in CloudTrail logs. For more information, see:

All Amazon ECR actions are logged by CloudTrail and are documented in the Amazon Elastic Container Registry API Reference. For example, calls to the GetAuthorizationToken, CreateRepository and SetRepositoryPolicy sections generate entries in the CloudTrail log files.

Every event or log entry contains information about who generated the request. The identity information helps you determine the following:

  • Whether the request was made with root or IAM user credentials.

  • Whether the request was made with temporary security credentials for a role or federated user.

  • Whether the request was made by another AWS service.

For more information, see the CloudTrail userIdentity Element.

Understanding Amazon ECR Log File Entries

A trail is a configuration that enables delivery of events as log files to an Amazon S3 bucket that you specify. CloudTrail log files contain one or more log entries. An event represents a single request from any source and includes information about the requested action, the date and time of the action, request parameters, and so on. CloudTrail log files are not an ordered stack trace of the public API calls, so they do not appear in any specific order.

Note

These examples have been formatted for improved readability. In a CloudTrail log file, all entries and events are concatenated into a single line. In addition, this example has been limited to a single Amazon ECR entry. In a real CloudTrail log file, you see entries and events from multiple AWS services.

The following example shows a CloudTrail log entry that demonstrates the CreateRepository action.
