Amazon ECR events and EventBridge - Amazon ECR
Sample events from Amazon ECR

Amazon ECR events and EventBridge

Amazon EventBridge enables you to automate your AWS services and to respond automatically to system events such as application availability issues or resource changes. Events from AWS services are delivered to EventBridge in near real time. You can write simple rules to indicate which events are of interest to you and include automated actions to take when an event matches a rule. The actions that can be automatically triggered include the following:

  • Adding events to log groups in CloudWatch Logs

  • Invoking an AWS Lambda function

  • Invoking Amazon EC2 Run Command

  • Relaying the event to Amazon Kinesis Data Streams

  • Activating an AWS Step Functions state machine

  • Notifying an Amazon SNS topic or an Amazon SQS queue

For more information, see Getting Started with Amazon EventBridge in the Amazon EventBridge User Guide.

Sample events from Amazon ECR

The following are example events from Amazon ECR. Events are emitted on a best effort basis.

Event for a completed image scan (basic scanning)

When basic scanning is enabled for your registry, the following event is sent when each image scan is completed. The finding-severity-counts parameter will only return a value for a severity level if one exists. For example, if the image contains no findings at CRITICAL level, then no critical count is returned. For more information, see Scan images for OS vulnerabilities in Amazon ECR.

Note

For details about events that Amazon Inspector emits when enhanced scanning is enabled, see EventBridge events sent for enhanced scanning in Amazon ECR.
