How to get the the event/binding context

[sl4dy]

Is there any way how to get the event/binding context without running the operator? I just need to make up the jq filter and/or prepare the operation logic first.

Hello @sl4dy. It feels like BindingContextGenerator is what you want.

func Test_BindingContextGenerator_Print(t *testing.T) {
	c := NewBindingContextController(`
configVersion: v1
kubernetes:
- apiVersion: v1
  includeSnapshotsFrom:
  - pods
  kind: Pod
  name: pods
`)

	// Synchronization contexts
	contexts, _ := c.Run(``)
	fmt.Println("Sync: ", contexts.Rendered)

	// Object added
	contexts, _ = c.ChangeState(`
---
apiVersion: v1
kind: Pod
metadata:
  name: pod1
`)
	fmt.Println("Added: ", contexts.Rendered)

	// Object deleted
	contexts, _ = c.ChangeState(``)
	fmt.Println("Deleted: ", contexts.Rendered)
}

Response:
