如何为自定义python项目编写Dockerfile? [英] How to write a Dockerfile for a custom python project?

问题描述

我是Docker的新手，我需要创建一个容器以将Docker容器作为Apache Mesos任务运行.

I'm pretty new to Docker, and I need to create the container to run Docker container as an Apache Mesos task.

问题是我找不到任何相关示例.它们全都围绕Web开发，这不是我的情况.

The problem is that I can't find any relevant examples. They all are centered around Web development, which is not my case.

我有一个具有大量依赖项的纯Python项目(例如Berkeley Caffe或OpenCV).如何编写Docker文件以正确注册所有依赖项(以及如何找出它们)?

I have a pure Python project with large number of dependencies ( like Berkeley Caffe or OpenCV ). How to write a Docker file to properly enroll all dependecies ( and how to find them out?)

推荐答案

docker hub注册表包含许多官方语言图像，您可以将其用作基础图像.

The docker hub registry contains a number of official language images, which you can use as your base image.

• https://hub.docker.com/_/python/

说明告诉您如何构建python项目，包括导入依赖项.

The instructions tell you how you can build your python project, including the importation of dependencies.

├── Dockerfile                <-- Docker build file
├── requirements.txt          <-- List of pip dependencies
└── your-daemon-or-script.py  <-- Python script to run

图像同时支持Python 2和Python 3，您可以在Dockerfile中指定它:

Image supports both Python 2 and 3, you specify this in the Dockerfile:

FROM python:3-onbuild
CMD [ "python", "./your-daemon-or-script.py" ]

基本映像使用特殊的 ONBUILD指令来完成所有的工作你.

The base image uses special ONBUILD instructions to all the hard work for you.
