This repository contains source code for Docker image designed to help you run your Tox tests with all available Python versions in Docker container.
Docker image is hosted on Docker Hub and build automatically after every push to master branch.
We usually add the newest Pythons to all supported Fedora releases. We also have to remove the oldest ones from time to time. These are the reasons why we move this container image from Fedora N to N+1 when N goes EOL.
On top of stable Fedora, this Docker image contains:
- Python 2.7, 3.6, 3.7, 3.8, 3.9, 3.10, 3.11, 3.12, 3.13
- Pypy2, Pypy3.9 and Pypy3.10
- python3-pip
- gcc, gcc-c++, git-core and make
- tox
- virtualenv
The image works very well with both Docker and Podman so you can use containers management tool you prefer.
If you want to use this Docker image as environmet for your test, use this command:
cd example_project
docker run --rm -it -v $PWD:/src -w /src fedorapython/fedora-python-tox
py27 create: /src/.tox/py27

Command and argument description:
docker run- run docker image--rm- automatically remove the container when it exits-i- keep STDIN open even if not attached-t- allocate a pseudo-TTY-v $PWD:/src- mount your current working directory to /src inside container-w- use /src (mountpoint) as working directory inside containerfedorapython/fedora-python-tox- name of Docker image
Tox is run automatically with this container. How cool!
You also can limit Tox tests by passing environment variable to Docker. For example:
cd example_project
docker run --rm -it -v $PWD:/src -w /src -e TOXENV=pypy3 fedorapython/fedora-python-tox
pypy3 create: /src/.tox/pypy3
pypy3 installdeps: pytest

congratulations :)
You can adjust the behavior of tox by setting TOX_PARAMS variable with any combination of CLI parameters. It's useful for example for parallel run of your tests.
docker run --rm -it -v $PWD:/src -w /src -e TOX_PARAMS="-p auto" fedorapython/fedora-python-tox

Instead of mounting local folder with source code into container, you can provide HTTPS URL of your GIT repository and it will be cloned automatically.
For example:
docker run --rm -it -e GIT_URL=https://github.com/fedora-python/pyp2rpm.git fedorapython/fedora-python-tox

Sometimes, your tests need some system packages (such as C libraries).
You can install them via dnf by setting the $DNF_INSTALL environment variable:
docker run --rm -it -v $PWD:/src -w /src -e DNF_INSTALL="libyaml-devel libgit2-devel" fedorapython/fedora-python-tox
...
Installed:
http-parser-2.9.3-2.fc32.x86_64 libgit2-1.0.1-2.fc32.x86_64
libgit2-devel-1.0.1-2.fc32.x86_64 libssh2-1.9.0-5.fc32.x86_64

Complete!
py27 create: /src/.tox/py27
...
You can install packages by any RPM Provides, for example:
- Fedora package names, e.g.
libgit2-devel, - pkgconfig names, e.g.
pkgconfig(libgit2), or - commands, e.g.
/usr/bin/cowsay.
If your tox.ini file is not in the root directory of your project, set WORKDIR to the path you want to cd to before the tests are executed.
