docker-centos7-poetry

Dockerfile for running Python 3.9 and poetry within a CentOS 7 container. This is useful for running Pyinstaller to generate executables that use older versions of GLIBC. E.g. see this discussion.

Example GitHub action that uses this container with PyInstaller

name: build-executables
on:
  workflow_dispatch:
jobs:
  build-executable-CentOS:
    runs-on: ubuntu-latest
    container:
      image: ghcr.io/hpcflow/centos7-poetry
    steps:
      - uses: actions/checkout@v2

      - name: Install dependencies
        run: poetry install

      - name: Run PyInstaller
        run: poetry run pyinstaller hpcflow/cli.py --name=hpcflow --onefile

Build steps (hosting in ghcr)

The version tag is specified after the :, and should include the python and poetry versions:

docker build -t ghcr.io/hpcflow/centos7-poetry:py3.9.16_po1.4.2 .
docker push ghcr.io/hpcflow/centos7-poetry:py3.9.16_po1.4.2

When updating the latest image use the tag latest:

docker build -t ghcr.io/hpcflow/centos7-poetry:latest .
docker push ghcr.io/hpcflow/centos7-poetry:latest

Make sure to push the image twice! Once with the version tag and another with the latest tag.

Note: you may have to login to ghcr before pushing. For that, first create a personal access token (Settings / Developer settings / New token (classic)) with permissions for write and delete packages. Copy the access token!

Then use your github username and the copied acces token to login with

docker login ghcr.io

You should now be ready to push.
