Python platform

The Python platform uses python 3.11.3 by default and get your dependencies with pip, either by Pipfile.lock, requirements.txt or setup.py.

You can define which python version you want using .python-version, always use full versions.

ex:

3.11.3

Available python versions:

  • 2.7.14
  • 3.5.10
  • 3.6.15
  • 3.7.16
  • 3.8.16
  • 3.9.16
  • 3.10.11
  • 3.11.3
  • pypy2.7-7.3.2
  • pypy3.6-7.3.2

when adding new releases, we will retain previous version on the series to allow time for users update their apps. e,g: when 3.6.3 is released, we will remove 3.6.1.

Setting pip version

By default, the latest pip version will be installed. If you want to use a specific version, set a PYTHON_PIP_VERSION environment variable. It accepts a specific version (PYTHON_PIP_VERSION=7.1.2) or a requirement specifier (PYTHON_PIP_VERSION="<10").

Code deployment

If you just run a tsuru app deploy of your code, tsuru will try to download all of your depencies using requirements.txt or setup script. You can customize this behavior, see the next section for more details.

Code deployment with dependencies

There are two ways to list the applications dependencies: requirements.txt or setup.py. The priority order is: requirements -> setup. The file should be in the root of deploy files.

Using Pipfile.lock

If you have a Pipfile.lock file, tsuru will use pipenv to install the dependencies of your application.

Using requirements.txt

You can define a file called requirements.txt that list all pip dependencies of your application, each line represents one dependency, here's an example:

$ cat requirements.txt

Flask==0.10.1
gunicorn==19.3.0

Using setup script

You can also define the setup script to list your dependencies, here's an example:

$ cat setup.py

from setuptools import setup, find_packages
setup(
    name="app-name",
    packages=find_packages(),
    description="example",
    include_package_data=True,
    install_requires=[
        "Flask==0.10.1",
        "gunicorn==19.3.0",
    ],
)

After invoking tsuru app-deploy, tsuru will receive your code and tell the platform to install all the dependencies using pipenv install --system --deploy, pip install -r requirements.txt or pip instal -e ./.
