我在读取和处理的 S3 存储桶中有多个文本文件。因此，我在 Kedro 数据目录中定义了 PartitionedDataSet，如下所示：

raw_data:
  type: PartitionedDataSet
  path: s3://reads/raw
  dataset: pandas.CSVDataSet
  load_args:
    sep: "\t"
    comment: "#"

此外，我实施了这个解决方案，通过环境变量（包括 AWS 密钥）从凭证文件中获取所有秘密。

当我使用一切在本地运行时kedro run一切正常，但是当我构建 Docker 映像（使用kedro-docker）并在 Docker 环境中运行管道时，kedro docker run使用选项并通过提供所有环境变量，--docker-args我得到以下错误：

kedro.io.core.DataSetError: No partitions found in `s3://reads/raw`

注意：管道在 Docker 环境中工作得很好，如果我将文件移动到某个本地目录，定义 PartitionedDataSet 并构建 Docker 映像并通过提供环境变量--docker-args

解决方案（至少在我的情况下）是在命令中提供AWS_DEFAULT_REGIONenv 变量。kedro docker run
