python 3.12 on Amazon Linux 2023

0

I'm trying to build a container to run on ECS with Amazon Linux 2023 as the base image. I'd like to use Python 3.12 to run an application on the container, and I'm having a hard time getting the package manager (dnf) to find Python 3.12.

The line...

RUN dnf -y install python3.12

...in my dockerfile fails with the following error:

0.605 No match for argument: python3.12                                                                                                                                                                                                  
0.614 Error: Unable to find a match: python3.12

How do I install Python 3.12 on Amazon Linux 2023 using dnf?

Why not try installing Python3.12 using pyenv as shown below?

FROM amazonlinux:2023

RUN dnf install -y git tar gcc \
                   zlib-devel bzip2-devel readline-devel \
                   sqlite sqlite-devel openssl-devel \
                   tk-devel libffi-devel xz-devel

RUN curl https://pyenv.run | bash && \
    echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc && \
    echo '[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc && \
    echo 'eval "$(pyenv init -)"' >> ~/.bashrc && \
    source ~/.bashrc && \
    pyenv install 3.12.4 && \
    pyenv global 3.12.4

    By the way, this method takes about 6 to 7 minutes to build. Once the build is complete, you can start the container from the image and check the Python version.

    [root@ip-172-31-33-20 ~]# docker build ./
[+] Building 367.4s (7/7) FINISHED

[root@ip-172-31-33-20 ~]# docker run -it 46dccd41afb4 /bin/bash
bash-5.2#
bash-5.2# python -V
Python 3.12.4

Looks like python3.11 is the latest available in the repos.

dnf list | grep python3

For anyone finding this old thread - Python 3.12 is now available. You may need to update your AL 2023 first, e.g. using:

sudo dnf --releasever=latest update
