泊坞窗。 如何运行烧瓶服务器主文件，以在更深的文件结构中启动服务器

Question

My flask app, the main file that starts the flask server on port 5000 is inside:

Server /main/core/setup.py

The Docker gives me this error and I know because it cannot find the setup.py :

ERROR: for flask_api  Cannot start service flask_api: oci runtime error: 
container_linux.go:265: starting container process caused "exec: 
\"/main/api/core\": stat /main/api/core: no such file or directory"

My error is inside the Dockerfile:

I change my default path of the setup.py from the Server/setup.py to Server/app/main/core/setup.py

Question how to start the server on this path

Dockerfile:

This is before I move the setup.py file that starts the server on port 5000

# FROM python:3.6-alpine
# ADD ./Server /app
# WORKDIR /app
# RUN pip install -r requirements.txt
# EXPOSE 5000
# CMD ["python", "api.py"]

This is after I move the file deeper

FROM python:3.6-alpine
ADD ./Server /app
WORKDIR /app
RUN pip install -r requirements.txt
EXPOSE 5000
ENTRYPOINT ["/main/core"]
CMD ["python", "setup.py"]

Any help how to hit the setup.py ??

There is a little mess with entrypoint ( https://docs.docker.com/engine/reference/builder/#entrypoint ) and workdir ( https://docs.docker.com/engine/reference/builder/#workdir ) Please remember that you can use WORKDIR multiple times.

Your setup.py should be in path:

Server/main/core/setup.py

I suppose that your Dockerfile should be:

FROM python:3.6-alpine
ADD ./Server /app
WORKDIR /app 
RUN pip install -r requirements.txt
EXPOSE 5000
WORKDIR /app/main/core
CMD ["python", "setup.py"]
