问题
I am new to Docker.I have a script named ApiClient.py. The ApiClient.py script asks the user to input some data such as user's email,password,the input file(where the script will get some input information) and the output file(where the results will be output).I have used this Dockerfile:
FROM python:3
WORKDIR /Users/username/Desktop/Dockerfiles
ADD . /Users/username/Desktop/Dockerfiles
RUN pip install --trusted-host pypi.python.org -r requirements.txt
EXPOSE 80
ENV NAME var_name
CMD ["python", "ApiClient.py"]
1st Issue: I have used this WORKDIR and ADD because thats where the input and output files exist.Is it wrong to declare these directories?
2n Issue: The script asks for the user to input some info such as the email and password.However when i run:
docker run -p 4000:80 newapp
I get the following error: username = ("Please enter your username")
EOFError:EOF when reading a line
Why am i geting this error?
回答1:
Use docker run -i -t <your-options>
So here, -i stands for interactive mode and -t will allocate a pseudo terminal for us.
Which in your scenario would be
docker run -p 4000:80 -it newapp
Hope it helps!

Lets make some necessary files as example
Dockerfile
FROM python
ADD . /python
WORKDIR /python
ENTRYPOINT ["python", "main.py"]
You want to run a script that will take two argument for input & output file
main.py
import sys
input_file = sys.argv[1]
output_file = sys.argv[2]
file = open(input_file, 'r')
print(file.read())
file = open(output_file, 'w')
file.write('Hello World')
Now build and run
$ docker build -t test .
$ docker run -it -v /tmp/python/:/python/data test data.txt data/output.txt
Your main.py will take input from /python/data.txt and write output in /python/data/output.txt
As /python/data is mounted into /tmp/python/, you will get output.txt in /tmp/python/ in your local
