This is a fork of the Cloudfoundry Python Buildpack that adds extra libraries for more complete Pillow/Pillow-SIMD support.
We've also added libexiv2 and libboost-python in order to support py3exiv2, for image metadata manipulation.
You can use this via:
cf push my_app -b https://github.com/springernature/python-pillow-buildpackThe bundle libwebp was built on an Ubuntu 18.04.5 VM:
sudo apt install build-essential autoconf libtool
WEBP_VERSION=1.2.1
curl -Lso- https://github.com/webmproject/libwebp/archive/v$WEBP_VERSION.tar.gz | tar xzf -
cd libwebp-$WEBP_VERSION
./autogen.sh
./configure --prefix=/home/vcap/deps/0/libwebp && make
sudo rm -rf /home/vcap/deps/0/libwebp
sudo make install
tar czvf libwebp-$WEBP_VERSION-cflinuxfs3.tgz -C /home/vcap/deps/0/libwebp .Steps to generate the included exiv2-0.27.5-cflinuxfs3.tgz (carried out in an Ubuntu 18.04.6):

A Cloud Foundry buildpack for Python based apps.
This buildpack supports running Django and Flask apps.
Official buildpack documentation can be found at python buildpack docs.
To build this buildpack, run the following commands from the buildpack's directory:
-
Source the .envrc file in the buildpack directory.
source .envrcTo simplify the process in the future, install direnv which will automatically source .envrc when you change directories.
-
Install buildpack-packager
go install github.com/cloudfoundry/libbuildpack/packager/buildpack-packager
-
Build the buildpack
buildpack-packager build [ --cached=(true|false) ]
-
Use in Cloud Foundry
Upload the buildpack to your Cloud Foundry and optionally specify it by name
cf create-buildpack [BUILDPACK_NAME] [BUILDPACK_ZIP_FILE_PATH] 1 cf push my_app [-b BUILDPACK_NAME]
Buildpacks use the Cutlass framework for running integration tests.
To test this buildpack, run the following commands from the buildpack's directory:
-
Source the .envrc file in the buildpack directory.
source .envrcTo simplify the process in the future, install direnv which will automatically source .envrc when you change directories.
-
Run unit tests
./scripts/unit.sh
-
Run integration tests
Buildpacks use the Cutlass framework for running integration tests against Cloud Foundry. Before running the integration tests, you need to login to your Cloud Foundry using the cf cli:
cf login -a https://api.your-cf.com -u name@example.com -p pa55woRD
Note that your user requires permissions to run
cf create-buildpackandcf update-buildpack. To run the integration tests, run the following command from the buildpack's directory:./scripts/integration.sh
-
Note: To run the network tests, you must have Docker installed.
