How to create a basic image of the Python runtime environment using Docker

1. Preparation

1.1 Download the Python installation package (Note: the Python version can be changed according to your needs)

Download from official website: https://www.python.org/downloads/source/

Local download address: 64-bit: https://www.jb51.net/softs/416037.html

32-bit: https://www.jb51.net/softs/543679.html

1.2Base image Ubuntu16.04

DockerHub pull

docker pull ubuntu:16.04

Local Ubuntu download address: https://www.jb51.net/softs/532597.html

docker load < ubuntu1604.tar

2. Production process

2.1 Dockerfile Writing

FROM ubuntu:16.04
MAINTAINER cc-man
#Add Python installation package ADD Python-3.5.0.tar.xz /opt 
#Update apt
RUN apt-get update && apt-get install -y 
#Install dependencies RUN apt-get install gcc -y && apt-get install make -y \
		&& apt-get install vim -y && apt-get install openssl -y \
		&& apt-get install libssl-dev -y && apt-get install python3-pip -y
RUN ./opt/Python-3.5.0/configure --prefix=/usr/local/python3.5 \
		&& make && make install
RUN mkdir /opt/myApp/
VOLUME ["/opt/myApp/"]
CMD [""]

Note: The python version can be changed according to your needs

2.2 Production

docker build -t ubuntu-16.04/python:3.5 .

Note: The image creation process requires downloading dependencies so you need to wait for a while.

docker run -i -t -v /root/software/:/mnt/software/ 117cbe7ba93b /bin/bash

2. Check the pip version

pip -V 

3. Run Python

1.1

python3.5

1.2

print("hello world") 

At this point we have completed the production of the Python basic environment image
