尝试将Python与Docker集成。 在代码的输入部分出现错误

Question

I have a very simple python script. I am trying to use it in a docker container.

Python file (computer.py)

import datetime
print("Welcome to virtual assistant.")
name = input("What is your name? ")
print("Welcome " + name)
def time():
print(datetime.datetime.now())
command = input("Would you like to know the time " + name + "?")
if command == "yes":
print(time())

And My docker file looks like this.(Docker)

FROM python:3

ADD computer.py /

CMD [ "python", "./computer.py" ]

Then I ran

docker build -t python-barcode .

Then

run python-barcode

I get this error

Traceback (most recent call last):
  File "./computer.py", line 4, in <module>
    name = input("What is your name? ")
EOFError: EOF when reading a line
Welcome to virtual assistant.
What is your name? %

It seems to run the code up untill I ask for input? Not even sure what would cause that. Any help would be greatly appreciated.

Answer 1

When you run a container with docker run , stdin is by default not connected, so anything that attempts to read interactive input will fail. You probably want to run:

docker run -it python-barcode

The -i leaves stdin connected, and the -t allocates a tty which is what you normally want to interactive input.

Answer 2

您可以使用-i和-t以交互方式运行容器

docker run -it python-barcode
