GraphicsMagick Buildpack

Purpose of this buildpack

By default, our runtime image embeds ImageMagick as image manipulation toolset. However, you may prefer to have GraphicsMagick tools installed alongside your application, this buildpack will fit this need.

Set up this buildpack for your application

This buildpack won’t work alone, you need to combine it with the buildpack of the technology you are using. To achieve that you need to setup the Multi Buildpack:

scalingo env-set BUILDPACK_URL=https://github.com/Scalingo/multi-buildpack.git

Then you have to write a .buildpacks file with the reference to this buildpack and the one you want to use:

https://github.com/Scalingo/graphicsmagick-buildpack.git
https://github.com/Scalingo/nodejs-buildpack.git

Add this file to your git repository:

git add .buildpacks
git commit -m "Setup .buildpacks to install GraphicsMagick alongside the application on Scalingo"

Deploy your application

git push scalingo master

Check everything is working

$ scalingo run gm version
