This project is an attempt at packaging the kapitan helm bindings separately from the kapitan project, in order to be able to "pip install" the helm bindings instead of having to build them inside the kapitan tree.
As a user of kapitan, the desired workflow to use the helm input type is:
pip install kapitan
pip install kapitan_helmThe approach taken by this project is to build the golang extension using
setuptools-golang.
This successfully builds a golang binary in shared library mode, that we then build a cffi wrapper for.
The compilation method used is "out-of-line" and "ABI mode" as described in https://cffi.readthedocs.io/en/latest/cdef.html
This blog post was very helpful to understand the various CFFI extensions used https://blog.schuetze.link/2018/07/21/a-dive-into-packaging-native-python-extensions.html
The following steps are required to build and publish the wheel(s) to pypi:
- In a virtualenv with the build dependencies available ('setuptools-golang', 'cffi>=1.0.0'), run
setuptools-golang-build-manylinux-wheels - Once the build process is over you can upload the resulting wheels (located in dist/):
twine upload --repository testpypi dist/**
