Migrate from flux installed via kustomize to flux bootstrap

[trahim]

I'm looking to move to using flux bootstrap for installation from using just kustomization(via Terraform but I think conceptually it doesn't matter). So all my controllers exist as deployments, what is the recommended way to migrate this? If there is one?

There is a migration guide from bootstrap to Flux Operator here: https://fluxcd.control-plane.io/operator/flux-bootstrap-migration/

If you are looking for a Terraform example see: https://github.com/controlplaneio-fluxcd/flux-operator/tree/main/config/terraform

If you want to migrate from bootstrap to just applying the Flux manifests with Terraform, you first need to run flux uninstall --keep-namespace which is safe as it doesn't remove any managed resources.

Apologies forgot to feedback here, I don't think this answers specifically what I was trying to do but the move was pretty much seamless. To give context again we had installed flux with kustomization via the Terraform provider. To move this to be managed flux bootstrap we just removed the old references from state and ran an apply which bounced all of the flux pods but kept all CRDs and then our installation was managed via flux bootstap
