+

+## Connect CodeFresh to the GKE cluster
+
+[The Terraform provider for CodeFresh doesn't offer a resource for Kubernetes clusters](https://github.com/codefresh-io/terraform-provider-codefresh/issues/20), so we have to set up the authentication manually by copying the different connection arguments and pasting them in the CodeFresh web UI.
+
+For example, to obtain the connection arguments for the test environment, run:
+
+```
+terraform output gw_test_cd_connection
+```
