Question

我在这里拥有能够创建映像的Dockerfile。问题在于，即使文件存在，程序执行也无法读取子目录路径中的文件。

EXPOSE 9000


RUN ls -la /product_info/key_matching/data

ENTRYPOINT ["sh", "-c", "python key_matching/key_matching_endpoint.py"]

当我运行docker run -p 9000:9000 product_info时遇到错误

Traceback (most recent call last):
  File "key_matching/key_matching_endpoint.py", line 5, in <module>
    from key_matching import find_keys
  File "/product_info/key_matching/key_matching.py", line 11, in <module>
    from label_keys import key_to_label
  File "/product_info/key_matching/label_keys.py", line 67, in <module>
    with open('data/all_keys_sorted.txt', 'r') as f:
IOError: [Errno 2] No such file or directory: 'data/all_keys_sorted.txt'

我可以在docker之外运行所有内容，也可以运行

的输出

RUN ls -la /product_info/key_matching/data

显示工作目录中存在文件data / all_keys_sorted.txt。

-rw-r--r-- 1 root root 45713 Sep  5 12:32 all_keys_sorted.txt
drwxr-xr-x 2 root root  4096 Sep  5 12:36 thresholds

当我在docker外部运行所有内容时，我无法理解其原因

Flask服务无法在Docker容器中运行
