Cloud Foundry Python Buildpack with Pillow support libraries

This is a fork of the Cloudfoundry Python Buildpack that adds extra libraries for more complete Pillow/Pillow-SIMD support.

You can use this via:

cf push my_app -b https://github.com/springernature/python-pillow-buildpack

Genereration of library binaries

libwebp

The 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 .

Cloud Foundry Python Buildpack

Join us on Slack

A Cloud Foundry buildpack for Python based apps.

This buildpack supports running Django and Flask apps.

Buildpack User Documentation

Official buildpack documentation can be found at python buildpack docs.

Building the Buildpack

To build this buildpack, run the following commands from the buildpack's directory:

1. Source the .envrc file in the buildpack directory.

   source .envrc

   To simplify the process in the future, install direnv which will automatically source .envrc when you change directories.

2. Install buildpack-packager

   go install github.com/cloudfoundry/libbuildpack/packager/buildpack-packager

3. Build the buildpack

   buildpack-packager build [ --cached=(true|false) ]

4. 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]

Testing

Buildpacks use the Cutlass framework for running integration tests.

To test this buildpack, run the following commands from the buildpack's directory:

1. Source the .envrc file in the buildpack directory.

   source .envrc

   To simplify the process in the future, install direnv which will automatically source .envrc when you change directories.

2. Run unit tests

   ./scripts/unit.sh

3. 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 [email protected] -p pa55woRD

   Note that your user requires permissions to run cf create-buildpack and cf update-buildpack. To run the integration tests, run the following command from the buildpack's directory:

   ./scripts/integration.sh

4. Note: To run the network tests, you must have Docker installed.
