The CDK Construct Library for AWS::ECR

Amazon ECR Construct Library

---

---

This package contains constructs for working with Amazon Elastic Container Registry.

Repositories

Define a repository by creating a new instance of Repository. A repository holds multiple verions of a single container image.

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
repository = ecr.Repository(self, "Repository")

Image scanning

Amazon ECR image scanning helps in identifying software vulnerabilities in your container images. You can manually scan container images stored in Amazon ECR, or you can configure your repositories to scan images when you push them to a repository. To create a new repository to scan on push, simply enable imageScanOnPush in the properties

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
repository = ecr.Repository(stack, "Repo",
    image_scan_on_push=True
)

To create an onImageScanCompleted event rule and trigger the event target

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
repository.on_image_scan_completed("ImageScanComplete").add_target(...)

Authorization Token

Besides the Amazon ECR APIs, ECR also allows the Docker CLI or a language-specific Docker library to push and pull images from an ECR repository. However, the Docker CLI does not support native IAM authentication methods and additional steps must be taken so that Amazon ECR can authenticate and authorize Docker push and pull requests. More information can be found at at Registry Authentication.

A Docker authorization token can be obtained using the GetAuthorizationToken ECR API. The following code snippets grants an IAM user access to call this API.

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
import aws_cdk.aws_iam as iam

user = iam.User(self, "User", ...)
iam.AuthorizationToken.grant_read(user)

Automatically clean up repositories

You can set life cycle rules to automatically clean up old images from your repository. The first life cycle rule that matches an image will be applied against that image. For example, the following deletes images older than 30 days, while keeping all images tagged with prod (note that the order is important here):

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
repository.add_lifecycle_rule(tag_prefix_list=["prod"], max_image_count=9999)
repository.add_lifecycle_rule(max_image_age=cdk.Duration.days(30))
