If you configure your k8s cluster with terraform one of the final steps is to install a fluxcd operator. The operator are responsible to manage the resources inside of the cluster. In this way a fully automatic creation process is possible. To install flux a terraform provider is available preparing a install and sync configuration which can be installed in k8s using the kubernetes/kubectl providers.
