Dockerfiles and helper scripts for multi-arch pyenv and tox on top of the pyenv images
Alpine and Debian based variants (just in case you have something that chokes on musl-libc on alpine). For weird corner cases there's also Ubuntu based image (in case there are some 3rd party binary only deps that don't work on the available debians)
Pre-built images for x64 and arm64 at https://hub.docker.com/r/advian/pyenv and https://hub.docker.com/r/advian/tox-base which has tox preinstalled and is generally the recommended starting point.
In your project Dockerfile just add a new target
FROM advian/tox-base:alpine as tox
That alone is enough unless you have special needs, then you can build and run the image:
docker build -t myproject:tox --target tox .
docker run --rm -it -v `pwd`:/app myproject:tox
If Alpine/musl-libc is a problem you can use :debian instead, if you really
need some packages only available for Ubuntu there's :ubuntu too.
This repo also has a minimal Python package and tox config for quick-testing
docker build --progress=plain -t toxtest --target tox -f Dockerfile_toxexample .
docker run --rm -it -v `pwd`:/app toxtest
It should be available as part of standard Docker packages these days.
In order to be able to build images for foreign architectures, the linuxkit/binfmt
image should pulled and run. This will make qemu-user-static
available on the host:
docker run --rm --privileged linuxkit/binfmt:bebbae0c1100ebf7bf2ad4dfb9dfd719cf0ef132 # latest as of 2022-11-15
docker buildx rm toxbuilder ; docker buildx create --name toxbuilder --config `pwd`/buildkitd.toml
docker buildx use toxbuilder
docker buildx inspect --bootstrap
export DHUBREPO=myrepo
./create_builds.py pyenv > pyenv.hcl
./create_builds.py tox-base > tox-base.hcl
docker login
docker buildx bake --push --file ./pyenv.hcl
docker buildx bake --push --file ./tox-base.hcl
The create_builds.py script output includes the Docker commands above as HCL file comments.
