如何使用docker run命令将json文件作为参数传递 [英] How to pass json file as an argument using docker run command

问题描述

以下是我的Dockerfile内容：

Below is my Dockerfile content:

FROM python:2.7-slim

# Set the working directory to /app
WORKDIR /app

# Copy the current directory contents into the container at /app
ADD . /app

RUN pip install numpy==1.12.0

CMD ["python", "t_1.py", "t_1.json"]

我想在运行时使用docker run命令将此文件（t_1.sjon）作为参数传递，以便CMD [ python ， t_1.py，运行时参数]。我尝试挂载卷，但是由于json文件是独立的并且我想作为参数而失败。

I want to pass this file(t_1.sjon) as argument with docker run command at runtime so that CMD ["python", "t_1.py", "RUN TIME ARGUMENT"]. I tried mounting volumes but fails as json file is independent and I want as argument.

请帮助。

推荐答案

您应该使用的是 ENTRYPOINT

FROM python:2.7-slim

# Set the working directory to /app
WORKDIR /app

# Copy the current directory contents into the container at /app
ADD . /app

RUN pip install numpy==1.12.0

ENTRYPOINT ["python", "t_1.py"]

现在，当您运行docker命令时

Now when you run the docker command

docker run -v ./t_1.json:/data/t_1.json <dockerimage> /data/t_1.json

这将使其等效于 python t_1。 py /data/t_1.json
