Nicholson Backflow Buildpack
This is a custom buildpack that will install pdftk into /app/bin on Heroku. Supports cedar-14, heroku-16, and heroku-18.
This will also hard force some default ENV variables like port, PATH, LD_LIBRARY etc...
modeled from https://github.com/ardalann/heroku-pdftk-buildpack
How to use
- Add this buildpack to your app.
How to upgrade PDFTK
Update the tarball_url line in scripts/build.sh
heroku create
heroku config:set BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-apt
git push heroku master
Now you'll have a new Heroku app on the default stack (currently cedar-14) that runs the scripts/build.sh script in this buildpack. That script will download the most recent PDFTK source and configure it with default options.
Use heroku logs -t to see when compilation is done. It'll start showing dots..
heroku open
- Download the generated pdftk.zip
- Chmod +x them
- put them into
bin/$STACK/into this buildpack. $STACK shall be the name of your stack as given in the Heroku $STACK variable.
heroku ps:scale web=0 to turn off the dyno.
