英文:
ModuleNotFoundError on Google Cloud Run, not locally
问题
我正在在Google Cloud Run上使用gunicorn部署Python Flask应用程序。容器在本地运行正常，但我注意到当我构建并推送服务修订版时，出现错误并且我的gunicorn工作进程崩溃：
ModuleNotFoundError: No module named 'lib'
我的目录结构如下：
├── Dockerfile
├── README.md
├── gunicorn.conf.py
├── lib
│ ├── __init__.py
│ └── misc
│ ├── __init__.py
│ └── daily_message.py
├── requirements.txt
└── server.py
我在server.py中像这样导入函数get_daily_message：
from lib.misc.daily_message import get_daily_message
这在本地和构建并在本地运行容器映像时都能正常工作。以下是我的Dockerfile。
# 使用官方的轻量级Python镜像。
# https://hub.docker.com/_/python
FROM python:3.11-slim
# 允许语句和日志消息立即出现在日志中
ENV PYTHONUNBUFFERED True
# 将本地代码复制到容器映像中。
ENV APP_HOME /app
WORKDIR $APP_HOME
# 将整个项目目录复制到容器中。
COPY . ./
# 安装生产依赖项。
RUN pip install --no-cache-dir -r requirements.txt
# 在容器启动时运行Web服务。
CMD ["gunicorn", "--bind", ":8080", "--workers", "2", "--threads", "4", "--timeout", "0", "server:app"]
英文:
I am deploying a Python Flask application behind gunicorn on Google Cloud run. The container runs fine locally, but I notice when I build and push the service revision I get an error and my gunicorn workers crash:
ModuleNotFoundError: No module named 'lib'
My directory structure is like so:
├── Dockerfile
├── README.md
├── gunicorn.conf.py
├── lib
│   ├── __init__.py
│   └── misc
│   ├── __init__.py
│   └── daily_message.py
├── requirements.txt
└── server.py
I import the function get_daily_message in server.py like so:
from lib.misc.daily_message import get_daily_message
This all works fine locally and also when I build and run my container image locally.
Here is my Dockerfile.
# Use the official lightweight Python image.
# https://hub.docker.com/_/python
FROM python:3.11-slim
# Allow statements and log messages to immediately appear in the logs
ENV PYTHONUNBUFFERED True
# Copy local code to the container image.
ENV APP_HOME /app
WORKDIR $APP_HOME
# Copy the entire project directory to the container.
COPY . ./
# Install production dependencies.
RUN pip install --no-cache-dir -r requirements.txt
# Run the web service on container startup.
CMD ["gunicorn", "--bind", ":8080", "--workers", "2", "--threads", "4", "--timeout", "0", "server:app"]

这里我来回答自己的问题。在从Artifact Registry拉取我的构件并进行检查后，我意识到lib目录没有被复制过来。原来，Google Cloud Build使用.gitignore文件来确定要与.dockerignore一起复制的内容。无法找到我的模块的原因是因为它没有被复制过来。
为了更好理解，我当时是部署到Cloud Run的：
gcloud builds submit ...
gcloud run deploy ...
英文:
Here I am to answer my own question. After pulling down my artifact from Artifact Registry and inspecting it, I realized the lib directory was not being copied over. It turns out Google Cloud Build uses the .gitignore file to determine what to copy over along with a .dockerignore. The reason my module could not be found was because it wasn't copied over.
For context I was deploying to Cloud Run:
gcloud builds submit ...
gcloud run deploy ...
