Integrate with Flux Receivers and Alerts

These docs show how to customize your Flux installation so that Flux API resources like Receivers and Alerts can be used with third-party custom resource definitions such as the Terraform API CRD.

You will need to add a patch to the kustomization.yaml in your Flux cluster installation's bootstrap manifests, find it under the flux-system directory.
