Recommended web frameworks include Django and Flask. The recommended webserver is Gunicorn. There are no restrictions around what software can be used (as long as it's pip-installable). Web processes must bind to
$PORT, and only the HTTP protocol is permitted for incoming connections.
Some Python packages with obscure C dependencies (e.g. scipy) are not compatible.
Deploying a Python application couldn't be easier:
$ ls Procfile requirements.txt web.py $ heroku create --buildpack https://github.com/andela-brotich/wger-buildpack-python.git $ git push heroku master ... -----> Python app detected -----> Installing python-2.7.13 $ pip install -r requirements.txt Collecting requests (from -r requirements.txt (line 1)) Downloading requests-2.12.4-py2.py3-none-any.whl (576KB) Installing collected packages: requests Successfully installed requests-2.12.4 -----> Discovering process types Procfile declares types -> (none)
requirements.txt file must be present at the root of your application's repository.
You can also specify the latest production release of this buildpack for upcoming builds of an existing application:
$ heroku buildpacks:set https://github.com/LarryWachira/wger-buildpack-python
Specific versions of the Python runtime can be specified with a
$ cat runtime.txt python-3.6.1
Runtime options include:
Copy the snippet above into CLI.
