我想将Docker镜像从本地磁盘上传到我使用AWS CDK创建的存储库中。
当我使用aws_ecr_assets.DockerImageAsset将Docker镜像添加到存储库中时(除了我无法通过CDK对其存储库设置权限外,它工作正常),我收到以下弃用警告:

DockerImageAsset.repositoryName is deprecated. Override "core.Stack.addDockerImageAsset" to control asset locations
当研究core.Stack.addDockerImageAsset时,我得到一个提示,我应该重写stack.synthesizer.addDockerImageAsset()
我的带有自定义合成器的简化堆栈如下所示:
class CustomSynthesizer(core.LegacyStackSynthesizer):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

    def add_docker_image_asset(
        self,
        *,
        directory_name,
        source_hash,
        docker_build_args=None,
        docker_build_target=None,
        docker_file=None,
        repository_name=None,
    ):
        # What should I put in this function to upload the docker image into my repository?


class ContainerStack(core.Stack):
    def __init__(self, scope: core.Construct, id: str, **kwargs) -> None:

        super().__init__(scope, id, synthesizer=CustomSynthesizer(), **kwargs)

        repo = ecr.Repository(self, "TestRepo", repository_name="test_repo")
        repo.grant_pull(iam.AccountPrincipal("123456789123"))

        image_location = self.synthesizer.add_docker_image_asset(
            directory_name="path/to/dir/with/Dockerfile",
            source_hash="latest",
            repository_name=repo.repository_name,
        )
我尝试过的另一件事是使用标准堆栈合成器,并在其上调用add_docker_image_asset。不幸的是,我收到以下错误消息,并且堆栈无法部署:
test-stack: deploying...
[0%] start: Publishing latest:current
[25%] fail: Unable to execute 'docker' in order to build a container asset. Please install 'docker' and try again.

对于如何解决此问题,我持坚定态度,非常感谢您的帮助!

最佳答案

DockerImageAsset是一个托管结构,它自己处理存储库和版本控制。默认情况下,它将为您的堆栈创建一个存储库,并将您的docker镜像上传到该存储库(通过其哈希标记它们)。
您不需要自己创建此存储库。但是,如果您像我一样,并且想使用一个清晰​​的存储库名称,则可以使用cdk.json配置文件及其context部分命名存储库:

// cdk.json
{
  "app": "python3 your_app",
  "context": {
    "@aws-cdk/core:enableStackNameDuplicates": "true",
    "aws-cdk:enableDiffNoFail": "true",
    "assets-ecr-repository-name": "<REPO NAME GOES HERE>"
  }
}
如果您想进一步更改存储库(我希望对其进行完全管理,但是,嘿),可以使用aws_ecr.Repository构造上的静态方法之一将存储库加载到CDK堆栈中。
https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-ecr.Repository.html#static-from-wbr-repository-wbr-namescope-id-repositoryname
希望这有所帮助 :-)
