如何从 spring 启动 java 应用程序在 Z05B6053C41A2130AFD6FC3BE158 中执行 python 程序

Question

I have spring boot java application. For some of its api, it calls a python program(which is present in src folder eg abc.py) to get the output.

I have a dockerfile to dockerize the application. I am able to successfully build the image and container is runnning out of the image. But when I call the api, it throws error and says python command not found. Also when I go inside docker container, when I check for ' which python ', it does not show anything.

For python install and making python environment variable set inside this docker, what should be mentioned in the dockerfile.

FROM gradle:4.10.1-jdk8-alpine AS build
COPY --chown=gradle:gradle . /home/gradle/src
WORKDIR /home/gradle/src
RUN gradle build --no-daemon

FROM python:3
ENV PYTHONUNBUFFERED 1
RUN mkdir -p /dispython
WORKDIR /dispython
COPY requirements.txt /dispython
RUN pip install --upgrade pip && \
    pip install --no-cache-dir -r requirements.txt
RUN python --version
RUN which python
#ENV PYTHONPATH "${PYTHONPATH}:/dispython"


FROM openjdk:8-jre-slim

EXPOSE 8081

RUN mkdir /app

COPY --from=build /home/gradle/src/build/libs/*.jar /app/spring-boot 
application.jar

ENTRYPOINT ["java", "-XX:+UnlockExperimentalVMOptions", "- 
             XX:+UseCGroupMemoryLimitForHeap", "- 
             Djava.security.egd=file:/dev/./urandom","-jar","/app/spring- 
             boot-application.jar"]

Advance thanks

If you really don't want to use docker-compose (recommended), you still have to copy this *.py file to your container COPY src/ src/ ...
