Manual test:

func TestGenTypes(t *testing.T) {
	buf := &bytes.Buffer{}
	if err := renderApisTypes(buf, "PlayService", "v1alpha1"); err != nil {
		t.Error(err)
		return
	}
	if err := ioutil.WriteFile("./types.go", buf.Bytes(), 0644); err != nil {
		t.Error(err)
	}
}

Output:

package v1alpha1

import (
	metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"
)

// +k8s:deepcopy-gen:interfaces=k8s.io/apimachinery/pkg/runtime.Object

type PlayServiceList struct {
	metav1.TypeMeta `json:",inline"`
	metav1.ListMeta `json:"metadata"`
	Items           []PlayService `json:"items"`
}

// +k8s:deepcopy-gen:interfaces=k8s.io/apimachinery/pkg/runtime.Object

type PlayService struct {
	metav1.TypeMeta   `json:",inline"`
	metav1.ObjectMeta `json:"metadata"`
	Spec              PlayServiceSpec   `json:"spec"`
	Status            PlayServiceStatus `json:"status,omitempty"`
}

type PlayServiceSpec struct {
	Replica int32 `json:"replica,omitempty"`
	// Fills me
}

type PlayServiceStatus struct {
	// Fills me
}

Hence, I just create a .tmpl file and let template.ParseFiles from it instead.

This would require to distribute the "tmpl" files along with the binary, right?
Initially we would distribute ONLY the binary.

Use this trick:

`...` + "`" + `json:"xxx,inline" + "`"

You are right on this. Let me try your trick!

PTAL cc/ @hongchaodeng @hasbro17
Due to hacking around backtick, the template looks a bit messy. FYI.
