Amazon ECR
User Guide (API Version 2015-09-21)

Viewing Repository Information

After you have created a repository, you can view its information in the AWS Management Console:

  • Which images are stored in a repository

  • Whether an image is tagged

  • The tags for the image

  • The SHA digest for the images

  • The size of the images in MiB

  • When the image was pushed to the repository


Beginning with Docker version 1.9, the Docker client compresses image layers before pushing them to a V2 Docker registry. The output of the docker images command shows the uncompressed image size, so it may return a larger image size than the image sizes shown in the AWS Management Console.
