Install Flux by referencing Big Bang's kustomization
As a user of this terraform module, I want Flux to be installed directly from Big Bang's kustomization, so that it is guaranteed to be the right version for my chosen version of Big Bang
Context:
- Right now we vendor the Flux k8s manifest in this repo, which is at risk of becoming out of date if we don't diligently keep it up to date with the upstream Big Bang project's version
