Python box

A wercker box with python 2.7 and 3.2 installed. For both versions of python setuptools, wheel, pip and virtualenv are installed.

There are two steps by default added to the wercker.yml:

• virtualenv which sets up a python virtual environment. Which is common practice in the python community. The virtual environment will also create/ enable some local caching for wercker.
• pip-install. This command by default tries to install the packages specified in the requirements.txt. There are several options for this. You can find more information in the steps directory on wercker

By default wercker will try to use wheel. Wheel is a built-package format which can speed up the build process. The wheel files are stored in your applications cache, which at this moment is stored for about two weeks. It may be a good idea to clear this cache every now and then.

Usage

The following is the default wercker.yml for python:

box: wercker/python
services:
    # - wercker/postgresql # Don't forget to add your databases as a service

# Build definition
build:

  # The steps that will be executed on build
  steps:
    - virtualenv:
        name: setup virtual environment

    - pip-install:
        requirements_file: "requirements.txt" # Optional argument.

    # A custom script step, name value is used in the UI
    # and the code value contains the command that get executed
    - script:
        name: echo python information
        code: |
          echo "python version $(python --version) running"
          echo "pip version $(pip --version) running"
          pip freeze
