Amazon Elastic Container Registry Public (Amazon ECR Public) is a fully managed registry that makes it easy for a developer to publicly share container software worldwide for anyone to download. Anyone (with or without an AWS account) can use Amazon ECR Public to pull container software for use. Amazon ECR Public Gallery is a website that allows anyone to browse and search for public container images, view developer-provided details, and see pull commands. Developers no longer need to use different private and public registries when building and sharing their public container artifacts. And everyone, including anonymous users and logged-in AWS customers, can now pull artifacts from a highly available public registry using a single, global registry URL when building and running their applications.
