redhat7 docker image: how to install python3

I need to install python3 inside an RH7 docker image. Unfortunately, I am new to RedHat, and it seems that installing that python version is rather complex. Can I have either some help or a working Docker file?

Solution

  • You can update your Dockerfile accordingly, to use a base image with the desired python version:

    enter image description here Example Red Hat Enterprise Linux Server release 7.9 (Maipo) image with python3 already installed:

    
$ docker run -itu 0 registry.access.redhat.com/ubi7/python-36 /bin/bash
