08/29/2018, 2:09 PMMy understanding is a resource provider has a specific grpc interface, and that tfgen is one way to generate a provider and it’s accompanying SDKs to implement it. You can also write non-Terraform-based providers which implement the interfaces directly like the Kubernetes one.

08/29/2018, 2:17 PMoh cool the Kubernetes provider is not based on tfgen because tfgen is only used to parse a tf provider and generate an SDK.

08/29/2018, 2:27 PMI just need confirmation that on a high level, a Pulumi provider based on a Terraform provider is wrapping the terraform provider and using rpc to communicate with it for CRUD operations.

08/29/2018, 2:31 PMAnd a Pulumi provider not based on a Terraform provider like the k8s one is implementing "by hand" all the CRUD operations instead of communicating with an underlying Terraform provider

08/29/2018, 2:33 PMAnd every provider is using rpc to communicate with the pulumi engine

08/29/2018, 2:39 PMYes that is correct

08/29/2018, 2:40 PMThere may be slightly more nuance that I haven’t got into (likely one of the Pulumi team can clarify that!) but that is my understanding

08/29/2018, 6:00 PMYou both have the right of it now. The GRPC interface that the providers implement is here: https://github.com/pulumi/pulumi/blob/master/sdk/proto/provider.proto

08/30/2018, 1:49 AMYes, just to be super clear, btw: the Kubernetes provider is 100% TF-free.
