Heroku buildpack: Buchner

This is a Heroku buildpack for Buchner (or any other Python) apps, powered by pip.

Usage

Example usage:

$ ls
Procfile  requirements.txt  web.py

$ heroku create --buildpack git://github.com/heroku/heroku-buildpack-python.git

$ git push heroku master
...
-----> Python app detected
-----> Installing runtime (python-2.7.9)
-----> Installing dependencies using pip
       Downloading/unpacking requests (from -r requirements.txt (line 1))
       Installing collected packages: requests
       Successfully installed requests
       Cleaning up...
-----> Discovering process types
       Procfile declares types -> (none)

You can also add it to upcoming builds of an existing application:

$ heroku config:add BUILDPACK_URL=git://github.com/heroku/heroku-buildpack-python.git

The buildpack will detect your app as Python if it has the file requirements.txt in the root.

It will use Pip to install your dependencies, vendoring a copy of the Python runtime into your slug.

Installing Node.js

If you create a package.json file within the root of the project, the buildpack will detect a Node.js dependency and install Node.js and npm.

Additional build related tasks

Sometimes you will have project specific tasks that need to be completed at build time. This may be something like asset bundling or running migrations.

You may provide a Buildfile file in the root, which is essentially a shell script to be run after all other standard build tasks are completed.

You may use the $BUILD_DIR variable to refer to the build directory within this file.

Specify a Runtime

You can also provide arbitrary releases Python with a runtime.txt file.

$ cat runtime.txt
python-3.4.3

Runtime options include:

• python-2.7.9
• python-3.4.3
• pypy-2.4.0 (unsupported, experimental)
• pypy3-2.4.0 (unsupported, experimental)

Other unsupported runtimes are available as well.
