An CDK Construct to synchronizes Docker images from Docker Hub to ECR.
npm install @pgarbe/cdk-ecr-syncAn CDK Construct to synchronizes Docker images from Docker Hub to ECR.
Why should you use it?
1. Avoid DockerHub throttling
2. Better availability (ECR: 99.9%, DockerHub: "as is")
3. Possible less data transfer costs (ECS pulls from ECR in same region are free)

In your CDK application, run npm install @pgarbe/cdk-ecr-sync and add the following construct:
``typescript
const ecrSync = new EcrSync(this, 'ecrSync', {
repoPrefix: 'dockerhub-mirror', // optional prefix
dockerImages: [
{
imageName: 'datadog/agent',
excludeTags: [ // Use RegEx expressions to exclude specific tags
'latest',
'^1.0'
],
}
],
lifcecyleRule: {...} // Optional lifecycle rule for ECR repos
});
// Allow all accounts in your organization to pull
ecrSync.grantPull(new iam.OrganizationalPrincipal('o-123456'));
`

Look up for a lambda called ecrSync%*`, add an empty test event, and execute it. The lambda will check which images needs to be synced and trigger a CodePipeline.
