CentOS with Python as base image

I created a Dockerfile and then built it for my team to use. Currently I am pulling from the CentOS:latest image, then building the latest version of Python and saving the image to a .tar file. The idea is for my colleagues to use this image to add their Python projects to the /pyscripts folder. Is this the recommended way of building a base image or is there a better way I can go about doing it?

# Filename: Dockerfile
From centos

RUN yum -y update && yum -y install gcc openssl-devel bzip2-devel libffi-devel wget make && yum clean all

RUN cd /opt && wget --no-check-certificate https://www.python.org/ftp/python/3.8.3/Python-3.8.3.tgz && tar xzf Python-3.8.3.tgz && cd Python-3.8*/ && ./configure --enable-optimizations && make altinstall && rm -rf /opt/Python* && mkdir /pyscripts

Many thanks!

Yes this is the standard and recommended way of building a base image from a parent image (CentOS in this example) if that is what you need Python 3.8.3 (latest version) on CentOS system.

Alternatively you can pull a generic Python image with latest Python version (which is now 3.8.3) but based on other Linux distribution (Debian) from Docker HUB repository by running:

docker pull python:latest

And then build a base image from it where you will just need to create the directory /pyscripts
So the Dockerfile would look like that: 

FROM python:latest
RUN mkdir /pyscripts

Or you can pull CentOS/Python already built image (with lower version 3.6) from Docker HUB repository by running:

docker pull centos/python-36-centos7

And then build a base image from it where you will just need to create the directory /pyscripts So the Dockerfile would look like that:

FROM centos/python-36-centos7:latest
USER root
RUN mkdir /pyscripts

Remember to add this line just after the first line to run the commands as root:

USER root

Otherwise you would get a Permission Denied error message
