在docker compose yml文件中设置环境变量时找不到文件错误

Question

I am setting the GOOGLE_APPLICATION_CREDENTIALS environment variable from within my docker-compose.yml file. This is the structure of my docker-compose.yml file:

version: "2"

services:

  server:
    container_name: server

    environment:
        - GOOGLE_APPLICATION_CREDENTIALS=/dir1/dir2/file1.json

My JSON file is present in the above directory. From my python code, which is also run as part of Docker container, I am using Google Speech API like this:

import io
from google.cloud import speech
from google.cloud.speech import enums
from google.cloud.speech import types

#take speech wav file and turn it into text. return text
def transcribe_file(speech_file):
    """Transcribe the given audio file."""
    client = speech.SpeechClient()

When I execute above it throws error that google.auth.exceptions.DefaultCredentialsError: File /dir1/dir2/file1.json was not found.

I am unable to understand why it is not able to find the JSON when it is present in the correct directory.

Make sure that you're adding /dir1/dir2/file1.json to your Docker image or mounting it as a volume. Having the file present at that location on the host isn't sufficient.
