与 AWS SDK或DescribeRepositories一起使用 CLI

以下代码示例演示如何使用 DescribeRepositories。

CLI

AWS CLI

在注册表中描述存储库

此示例将描述账户默认注册表中的存储库。

命令:

aws ecr describe-repositories

输出：

{
    "repositories": [
        {
            "registryId": "012345678910",
            "repositoryName": "ubuntu",
            "repositoryArn": "arn:aws:ecr:us-west-2:012345678910:repository/ubuntu"
        },
        {
            "registryId": "012345678910",
            "repositoryName": "test",
            "repositoryArn": "arn:aws:ecr:us-west-2:012345678910:repository/test"
        }
    ]
}
