How to install python specific version on docker?


I need to install python 3.8.10 in a container running ubuntu 16.04.

16.04 has no support anymore, so I need a way to install it there manually.

This follows from here

Add the following to your dockerfile, and change the python version as needed.

When the docker is up, python3.8 will be available in /usr/local/bin/python3.8

# compile python from source - avoid unsupported library problems
RUN apt update -y && sudo apt upgrade -y && 
    apt-get install -y wget build-essential checkinstall  libreadline-gplv2-dev  libncursesw5-dev  libssl-dev  libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev libffi-dev zlib1g-dev && 
    cd /usr/src && 
    sudo wget && 
    sudo tar xzf Python-3.8.10.tgz && 
    cd Python-3.8.10 && 
    sudo ./configure --enable-optimizations && 
    sudo make altinstall

Please note the following (standard [and quicker] way of installing) does not work for old ubuntu versions, due to end of support

RUN apt-get update && 
    apt-get install -y software-properties-common && 
    add-apt-repository -y ppa:deadsnakes/ppa && 
    apt-get update && 
    apt install -y python3.8
