AWS::ECR::PublicRepository - Amazon CloudFormation
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).


The AWS::ECR::PublicRepository resource specifies an Amazon Elastic Container Registry Public (Amazon ECR Public) repository, where users can push and pull Docker images, Open Container Initiative (OCI) images, and OCI compatible artifacts. For more information, see Amazon ECR public repositories in the Amazon ECR Public User Guide.


To declare this entity in your Amazon CloudFormation template, use the following syntax:


{ "Type" : "AWS::ECR::PublicRepository", "Properties" : { "RepositoryCatalogData" : RepositoryCatalogData, "RepositoryName" : String, "RepositoryPolicyText" : Json, "Tags" : [ Tag, ... ] } }


Type: AWS::ECR::PublicRepository Properties: RepositoryCatalogData: RepositoryCatalogData RepositoryName: String RepositoryPolicyText: Json Tags: - Tag
