Golang api.GetPartialReference函数代码示例

// GenerateContainerRef returns an *api.ObjectReference which references the given container
// within the given pod. Returns an error if the reference can't be constructed or the
// container doesn't actually belong to the pod.
//
// This function will return an error if the provided Pod does not have a selfLink,
// but we expect selfLink to be populated at all call sites for the function.
