我跟着the tutorial如何使用ubuntu在aws上创建一个k8s集群。这很好用，所以我有一个主节点和三个节点 - 小兵。但是，我没有找到任何正在运行的工作方法如何将新节点添加到群集中。
由于我没有找到任何教程，也许我需要做一些手动程序。但这将是一种奇怪的自动缩放。我应该做些什么？ kube脚本安装集群，添加扩展组，它不起作用？
Add more nodes in a second zone部分的this article中找到了一个引用，请注意这是关于多区域部署。所以我尝试过这样的事情：
KUBE_USE_EXISTING_MASTER=true KUBERNETES_PROVIDER=aws KUBE_AWS_ZONE=eu-central-1b NUM_NODES=1 KUBE_SUBNET_CIDR=172.20.1.0/24 MASTER_INTERNAL_IP=172.20.0.9 kubernetes/cluster/kube-up.sh
但总是失败：
A client error (AlreadyExists) occurred when calling the CreateLaunchConfiguration operation: Launch Configuration by this name already exists - A launch configuration already exists with the name kubernetes-minion-group-eu-central-1b
肯定有一些方法可以做到这一点，你能帮助别人吗？谢谢！

经过一些尝试后，似乎自动缩放组使用了debian图像。请注意，它需要aprox。实例准备就绪后2分钟，包含所有已安装的必需品，您可以使用import random
Battleship_Board = []
for x in range(0,5):
Battleship_Board.append(["O"] * 5)
def print_Battleship_Board(Battleship_Board):
for row in Battleship_Board:
print (" ".join(row))
print ("Let's play a game of Battleships!")
print_Battleship_Board(Battleship_Board)
def Random_Battleship_Board_Row(Battleship_Board):
return random.randint(0, len(Battleship_Board)-1)
def Random_Battleship_Board_Column(Battleship_Board):

Battleship_Board_Row = Random_Battleship_Board_Row(Battleship_Board)
Battleship_Board_Column = Random_Battleship_Board_Column(Battleship_Board)
print (Battleship_Board_Row)
print (Battleship_Board_Column)
for turn in range(5):
Guess_Battleship_Board_Row = int(input("Guess the X coordinate:")) -1
Guess_Battleship_Board_Column = int(input("Guess the Y coordinate:")) -1

print ("My ship was here: [" + str(Battleship_Board_Row) + "][" + str(Battleship_Board_Column) + "]")
break
else:
if turn + 1 == 5:
Battleship_Board[Guess_Battleship_Board_Row][Guess_Battleship_Board_Column] = "X"
print_Battleship_Board(Battleship_Board)
print ("Game Over")
print ("My ship was here: [" + str(Battleship_Board_Row) + "][" + str(Battleship_Board_Column) + "]")
if (Guess_Battleship_Board_Row < 0 or Guess_Battleship_Board_Row > 4) or (Guess_Battleship_Board_Column < 0 or Guess_Battleship_Board_Column > 4):
print ("The inserted value is not on the grid.")
elif(Battleship_Board[Guess_Battleship_Board_Row-1][Guess_Battleship_Board_Column-1] == "X"):

print_Battleship_Board(Battleship_Board)
