在下文中一共展示了InsertInstructions函数的2个代码示例，这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞，您的评价将有助于我们的系统推荐出更棒的Golang代码示例。

示例1: insertEnvAfterFrom

// insertEnvAfterFrom inserts an ENV instruction with the environment variables
// from env after every FROM instruction in node.
func insertEnvAfterFrom(node *parser.Node, env []kapi.EnvVar) error {
	if node == nil || len(env) == 0 {
		return nil
	}

	// Build ENV instruction.
	var m []dockerfile.KeyValue
	for _, e := range env {
		m = append(m, dockerfile.KeyValue{Key: e.Name, Value: e.Value})
	}
	buildEnv, err := dockerfile.Env(m)
	if err != nil {
		return err
	}

	// Insert the buildEnv after every FROM instruction.
	// We iterate in reverse order, otherwise indices would have to be
	// recomputed after each step, because we're changing node in-place.
	indices := dockerfile.FindAll(node, dockercmd.From)
	for i := len(indices) - 1; i >= 0; i-- {
		err := dockerfile.InsertInstructions(node, indices[i]+1, buildEnv)
		if err != nil {
			return err
		}
	}

	return nil
}

示例2: appendKeyValueInstruction

// appendKeyValueInstruction is a primitive used to avoid code duplication.
// Callers should use a derivative of this such as appendEnv or appendLabel.
// appendKeyValueInstruction appends a Dockerfile instruction with key-value
// syntax created by f as the last child of node with keys and values from m.
func appendKeyValueInstruction(f func([]dockerfile.KeyValue) (string, error), node *parser.Node, m []dockerfile.KeyValue) error {
	if node == nil {
		return nil
	}
	instruction, err := f(m)
	if err != nil {
		return err
	}
	return dockerfile.InsertInstructions(node, len(node.Children), instruction)
}
