Flux Python Bindings

Hello! You've found the flux Python bindings, an experiment to build and deploy Flux to Pypi without needing to store code alongside Flux. The goal of this experiment is to test them separately.

Development

We provide a .devcontainer environment you can open in VSCode to have an environment ready to go with Flux (and Flux Security). You can follow the instructions in the DevContainer to build the Flux Python bindings.

Building Modules

We will need to build the tarball providing paths to the flux-core and flux-security sources. This can be improved upon to just be one path if all the dependencies are provided with the flux install (and we don't need the source):

# Generate the wheel (requires pip install wheel)
$ python3 setup.py sdist bdist_wheel --flux-root /home/vscode/flux-core --security-src /home/vscode/security --security-include /usr/local/include/flux/security

You can then install the wheel (as a user or to the root)

$ pip install dist/flux-0.46.0-cp38-cp38-linux_x86_64.whl --user
$ sudo pip install dist/flux-0.46.0-cp38-cp38-linux_x86_64.whl 

Processing ./dist/flux-0.46.0-cp38-cp38-linux_x86_64.whl
Requirement already satisfied: cffi>=1.1 in /usr/lib/python3/dist-packages (from flux==0.46.0) (1.14.0)
Installing collected packages: flux
Successfully installed flux-0.46.0

If the development container you are using still installs the Python bindings, you'll want to do the sudo variant above to override. And then start a flux instance:

$ flux start --test-size=4

And import flux.

$ ipython

import flux
flux.Flux()

More coming soon! We still need to:

• some version checking
• ability to build .tar.gz (needed flux deps to be removed)
