ECR Images and layers

Question

I'm looking to find out the size of all the layers that they are using. I will use this information to calculate the storage costs for these layers. In addition, they Forecast Different Lifecycle Policies. I would like to get this information without pulling down all the layers. We are looking to query.
Is there an ECR API that can return all the layers and the size of the layers without walking them?

Accepted Answer

We can use the AWS CLI to find the size of all the layers in an ECR image without pulling down the layers using below ECR CLI command:

aws ecr batch-get-image --repository-name  --image-ids imageDigest-

To find out image digest run use below ECR CLI command:

aws ecr list-images --repository-name  --region

We can also use the command below to achive that.
docker buildx imagetools inspect --raw $IMAGE_NAME:$IMAGE_TAG
