与 AWS SDK或GetRepositoryPolicy一起使用 CLI

以下代码示例演示如何使用 GetRepositoryPolicy。

操作示例是大型程序的代码摘录，必须在上下文中运行。在以下代码示例中，您可以查看此操作的上下文：

• 了解基础知识

CLI

AWS CLI

检索存储库的存储库策略

以下get-repository-policy示例显示了有关存储库存储库策略的cluster-autoscaler详细信息。

aws ecr get-repository-policy \
    --repository-name cluster-autoscaler

输出：

{
    "registryId": "012345678910",
    "repositoryName": "cluster-autoscaler",
    "policyText": "{\n  \"Version\" : \"2008-10-17\",\n  \"Statement\" : [ {\n    \"Sid\" : \"allow public pull\",\n    \"Effect\" : \"Allow\",\n    \"Principal\" : \"*\",\n    \"Action\" : [ \"ecr:BatchCheckLayerAvailability\", \"ecr:BatchGetImage\", \"ecr:GetDownloadUrlForLayer\" ]\n  } ]\n}"
}
