The makefiles rely on being logged into to Docker Hub to properly scope the image tag.

git clone --recurse-submodules https://github.com/python-pillow/docker-images.git
cd docker-images
# update all the base images
make update
# build all of the test images
make build
# build and run the test suite on all the images
make test
# Push to Docker Hub
make push

All the makefile commands work in the individual directories.

cd alpine && make update && make && make test

If a shell would be useful in the environment, make shell will start the container with bash.

• Make a new directory for the platform
• ln -s ../Makefile.sub Makefile
• Write a simple update script to install the original image.
• Write/customize a Docker file. The convention is that the Pillow directory will be mounted at /Pillow, and the test script will run as the pillow user. Sudo is not available at test time.

To push an update of Pillow to this repository, run ./update-pillow.sh [[release tag]]
