type FilterContext

type FilterContext struct {
	// Obj contains the object submitted to the webhook (currently only pods)
	Obj metav1.Object `json:"obj,omitempty"`

	// Container contains the currently processed container
	Container corev1.Container `json:"container,omitempty"`
}

FilterContext is being used by JMESPath to search and match
