Sure, Crossplane leverages the K8s control plane for managing desired state for systems outside of the kubernetes cluster. It functions in a very similar fashion to terraform but it’s storing its own state in etcd instead of another state store. That makes GitOps + Crossplane play really nicely together and avoid the extra complexity that happens with terraform apply operations. They have a terraform wrapper provider for importing existing config and state.
It’s really nice to have infra and apps flow through the same pipes.
