GitHub Actions for Python projects using poetry
Getting started
Breaking changes for v2
We've drastically simplified this GitHub Action for v2.
This is no longer a Docker action that runs as its own container,
it's just a simplified way for you to install poetry.
This action now makes an assumption that you've already setup Python via setup-python or some other way.
Since we're installing poetry directly to your environment,
this also means that you can cache your dependencies more easily since everything is running on the host runner instead of an isolated container environment.

It is possible to combine actions/poetry with actions/cache to speed up the installation of dependencies.
The recipe is:
- to ask
poetryto create a virtual environment inside the project: it creates a local.venv/folder that can be cached - to create a cache key that involves the contents of the
poetry.lockfile: if the contents change (meaning that dependencies have changed), then the cache needs to be invalidated and recreated
For the 1st step, you either need:
- to have a
poetry.tomlfile at the root of your project with these 2 settings:
[virtualenvs]
create = true
in-project = true- or to run the following commands in the github actions to create the
poetry.tomlfile:
poetry config virtualenvs.create true --local
poetry config virtualenvs.in-project true --localHere is an example of how the steps must be declared:
jobs:
ci:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- name: Install Python
uses: actions/setup-python@v4
# see details (matrix, python-version, python-version-file, etc.)
# https://github.com/actions/setup-python
- name: Install poetry
uses: abatilo/actions-poetry@v2
- name: Setup a local virtual environment (if no poetry.toml file)
run: |
poetry config virtualenvs.create true --local
poetry config virtualenvs.in-project true --local
- uses: actions/cache@v3
name: Define a cache for the virtual environment based on the dependencies lock file
with:
path: ./.venv
key: venv-${{ hashFiles('poetry.lock') }}
- name: Install the project dependencies
run: poetry install
- name: Run the automated tests (for example)
run: poetry run pytest -vLicense
