This is an ubuntu based docker image for tox.
If you're looking to avoid pyenv or need a single image for your CI that has py2/3 and tox preinstalled, you found a solution.
Usage:
$ docker run --rm -it -v `pwd`:/app omercnet/tox
Or if you're into alpine:
$ docker run --rm -it -v `pwd`:/app omercnet/tox:alpine
You can also use 'natively' adding this to your shell rc:
$ alias tox='docker run --rm -it -v `pwd`:/app omercnet/tox
$ tox --help
