setup-python-amazon-linux

Github action to install python in amazon linux. The goal of this action is to be a drop in replacement for the Github's official setup-python action to the maximum extent possible.

Why?

• This project exists because, as of Nov 2023 Github has no plans support amazon linux in the foreseeable future for its official setup-python action for amazon linux self-hosted runners.

Usage

All you have to do is change "setup-python" to "setup-python-amazon-linux" in your workflows

steps:
- uses: actions/checkout@v3
- uses: kishaningithub/setup-python-amazon-linux@v1
  with:
    python-version: '3.10'
- run: python my_script.py

The python-version input is optional. If not supplied, the action will try to resolve the version from the default .python-version file. Highly recommend always setting Python version explicitly using the python-version or python-version-file inputs.

steps:
- uses: kishaningithub/setup-python-amazon-linux@v1
  with:
    python-version-file: '.python-version'

For more options to the action, kindly refer action.yml

Supported amazon linux flavours

• Amazon Linux 2
• Amazon Linux 2023

If you need support for more kindly raise an issue or a PR

Implementation caveat

This action compiles the desired version of python from source for the first time because the glibc version in use in amazon linux 2 is very old (2.26) and the pre-made existing binary distributions fail with the following error

python: /lib64/libc.so.6: version `GLIBC_2.27' not found
python: /lib64/libc.so.6: version `GLIBC_2.28' not found

Hence, only for the first time this action may like 3 to 4 minutes depending on the runner configuration. Post this only cache will be used and hence will be very fast (4 to 5 seconds)
