cdk-ecr-deployment

CDK construct to synchronize single docker image between docker registries.

Only use v3 of this package

⚠️ Version 2. is no longer supported, as the Go.1.x runtime is no longer supported in AWS Lambda.\ ⚠️ Version 1. is no longer supported, as CDK v1 has reached the end-of-life stage.

Features

• Copy image from ECR/external registry to (another) ECR/external registry
• Copy an archive tarball image from s3 to ECR/external registry

Environment variables

Enable flags: true, 1. e.g. export CI=1

• CI indicate if it's CI environment. This flag will enable building lambda from scratch.
• NO_PREBUILT_LAMBDA disable using prebuilt lambda.
• FORCE_PREBUILT_LAMBDA force using prebuilt lambda.

⚠️ If you want to force using prebuilt lambda in CI environment to reduce build time. Try export FORCE_PREBUILT_LAMBDA=1.

Examples

import { DockerImageAsset } from 'aws-cdk-lib/aws-ecr-assets';

const image = new DockerImageAsset(this, 'CDKDockerImage', {
  directory: path.join(__dirname, 'docker'),
});

// Copy from cdk docker image asset to another ECR.
new ecrdeploy.ECRDeployment(this, 'DeployDockerImage1', {
  src: new ecrdeploy.DockerImageName(image.imageUri),
  dest: new ecrdeploy.DockerImageName(`${cdk.Aws.ACCOUNT_ID}.dkr.ecr.us-west-2.amazonaws.com/my-nginx:latest`),
});

// Copy from docker registry to ECR.
new ecrdeploy.ECRDeployment(this, 'DeployDockerImage2', {
  src: new ecrdeploy.DockerImageName('nginx:latest'),
  dest: new ecrdeploy.DockerImageName(`${cdk.Aws.ACCOUNT_ID}.dkr.ecr.us-west-2.amazonaws.com/my-nginx2:latest`),
});

// Copy from private docker registry to ECR.
// The format of secret in aws secrets manager must be plain text! e.g. <username>:<password>
new ecrdeploy.ECRDeployment(this, 'DeployDockerImage3', {
  src: new ecrdeploy.DockerImageName('javacs3/nginx:latest', 'username:password'),
  // src: new ecrdeploy.DockerImageName('javacs3/nginx:latest', 'aws-secrets-manager-secret-name'),
  // src: new ecrdeploy.DockerImageName('javacs3/nginx:latest', 'arn:aws:secretsmanager:us-west-2:000000000000:secret:id'),
  dest: new ecrdeploy.DockerImageName(`${cdk.Aws.ACCOUNT_ID}.dkr.ecr.us-west-2.amazonaws.com/my-nginx3:latest`),
}).addToPrincipalPolicy(new iam.PolicyStatement({
  effect: iam.Effect.ALLOW,
  actions: [
    'secretsmanager:GetSecretValue',
  ],
  resources: ['*'],
}));

Sample: test/example.ecr-deployment.ts

Tech Details & Contribution

The core of this project relies on containers/image which is used by Skopeo. Please take a look at those projects before contribution.

To support a new docker image source(like docker tarball in s3), you need to implement image transport interface. You could take a look at docker-archive transport for a good start.

To test the lambda folder, make test.
