We started looking into implementing FluxCD, thanks @cdenneen for joining the project

First attempt at this: https://github.com/cdenneen/gitops-bridge-fluxcd-bootstrap-terraform/tree/helm_values

Things found that would make this easier to setup if implemented in FluxCD:

• support downwardAPI (mustache grabs {{}})
• support some way to have Kustomization include/exclude instead of generating blanket kustomization.yaml to include all (maybe better way would be to include/exclude HelmReleases found by having annotation HelmRelease will read to enable or disable itself. Something like toolkit.fluxcd.io/<helmreleasename>: enable)
