Flux All-In-One is an experimental distribution made with cuelang for running Flux on Kubernetes clusters without a CNI plugin being installed in advance.
The main difference to the upstream distribution, is that Flux AIO bundles all the controllers into a single Kubernetes Deployment. The communication between controllers happens on the loopback interface, hence Flux can function on clusters which don't have a CNI plugin installed. This allows Kubernetes operators to setup their clusters networking in a GitOps way.
Start by cloning the repository locally:
git clone https://github.com/stefanprodan/flux-aio.git
cd flux-aioInstall cue, kubectl and flux with Homebrew:
brew bundleThe complete list of tools can be found in the Brewfile.
Deploy Flux AIO on your cluster with cue install:
$ cue install
