@aws-cdk/aws-ecr
Advanced tools
@aws-cdk/aws-ecr is an AWS Cloud Development Kit (CDK) library that allows you to define and manage Amazon Elastic Container Registry (ECR) resources using code. ECR is a fully managed Docker container registry that makes it easy to store, manage, and deploy Docker container images.
Create a new ECR Repository
This code sample demonstrates how to create a new ECR repository named 'my-repo' using the AWS CDK.
const ecr = require('@aws-cdk/aws-ecr');
const cdk = require('@aws-cdk/core');
class MyStack extends cdk.Stack {
constructor(scope, id, props) {
super(scope, id, props);
new ecr.Repository(this, 'MyRepository', {
repositoryName: 'my-repo'
});
}
}
const app = new cdk.App();
new MyStack(app, 'MyStack');Add lifecycle policy to ECR Repository
This code sample demonstrates how to add a lifecycle policy to an ECR repository to retain only the last 5 images with the 'prod' tag.
const ecr = require('@aws-cdk/aws-ecr');
const cdk = require('@aws-cdk/core');
class MyStack extends cdk.Stack {
constructor(scope, id, props) {
super(scope, id, props);
const repository = new ecr.Repository(this, 'MyRepository', {
repositoryName: 'my-repo'
});
repository.addLifecycleRule({
tagPrefixList: ['prod'],
maxImageCount: 5
});
}
}
const app = new cdk.App();
new MyStack(app, 'MyStack');Grant permissions to a user
This code sample demonstrates how to grant pull permissions to an IAM user for an ECR repository.
const ecr = require('@aws-cdk/aws-ecr');
const iam = require('@aws-cdk/aws-iam');
const cdk = require('@aws-cdk/core');
class MyStack extends cdk.Stack {
constructor(scope, id, props) {
super(scope, id, props);
const repository = new ecr.Repository(this, 'MyRepository', {
repositoryName: 'my-repo'
});
const user = new iam.User(this, 'MyUser');
repository.grantPull(user);
}
}
const app = new cdk.App();
new MyStack(app, 'MyStack');The aws-sdk package is the official AWS SDK for JavaScript, which provides a comprehensive set of tools for interacting with AWS services, including ECR. Unlike @aws-cdk/aws-ecr, which is used for defining infrastructure as code, aws-sdk is used for making API calls to AWS services.
The serverless framework is a toolkit for deploying and operating serverless architectures. It supports various AWS services, including ECR, for managing container images. While @aws-cdk/aws-ecr focuses on infrastructure as code, serverless provides a higher-level abstraction for deploying serverless applications.
Terraform is an open-source infrastructure as code software tool that provides a consistent CLI workflow to manage hundreds of cloud services, including AWS ECR. Terraform and @aws-cdk/aws-ecr both serve the purpose of defining cloud infrastructure, but Terraform is cloud-agnostic and can be used with multiple cloud providers.
This package contains constructs for working with Amazon Elastic Container Registry.
Define a repository by creating a new instance of Repository. A repository
holds multiple verions of a single container image.
const repository = new ecr.Repository(this, 'Repository');
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 reposity to scan on push, simply enable imageScanOnPush in the properties
const repository = new ecr.Repository(stack, 'Repo', {
imageScanOnPush: true
});
To create an onImageScanCompleted event rule and trigger the event target
repository.onImageScanCompleted('ImageScanComplete')
.addTarget(...)
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):
repository.addLifecycleRule({ tagPrefixList: ['prod'], maxImageCount: 9999 });
repository.addLifecycleRule({ maxImageAge: cdk.Duration.days(30) });
