Got it working right after sending the message. What I did was (using F#):

let provider =
        Pulumi.Kubernetes.Provider("k8s",
            Pulumi.Kubernetes.ProviderArgs(
                KubeConfig = io cluster.KubeConfigRaw
            )        
        )

...
    let options = ComponentResourceOptions(Provider = provider)

    ConfigFile("something",
        ConfigFileArgs(
            File = input "manifests/something.yaml"
        ), options = options) |> ignore
