Bug Report

What did you do?

I was following the Quick Start guide to create a project and when add api it fails with error, Hit an unsupported type invalid type for invalid type, from ./pkg/apis/app/v1alpha1.AppService.

What did you see instead? Under which circumstances?

This is the error I saw in a brand new project:

$ operator-sdk add api --api-version=app.example.com/v1alpha1 --kind=AppService

• Kubernetes cluster kind:

minikube

• Are you writing your operator in ansible, helm, or go?

golang

[pzghost]

Maybe the operator-sdk cann't get your GOROOT, you should set it obviously.
e.g.

[pzghost@localhost app-operator]$ echo $GOROOT

[pzghost@localhost app-operator]$ operator-sdk add api --api-version=app.example.com/v1alpha1 --kind=AppService

That is my GOROOT as well:

$ go env GOROOT
/usr/local/go

If that is default why do I have to set it again?

[joelanford]

This is a known issue. See #1854 (comment)

If setting GOROOT doesn't resolve this, we can re-open.

[dmvolod]

@joelanford I can see, that PR #2754 introduce to set GOROOT on k8s generating and create API. I tried to call
operator-sdk add api ... and it still doesn't work
