使用 cloudformation 将嵌套堆栈创建的 ec2 实例附加到负载均衡器堆栈

Question

我使用嵌套堆栈创建了两个 Web 服务器。还为负载均衡器创建了单独的嵌套堆栈。我想附加两个使用 Load balancder 创建的网络服务器。我真的对嵌套堆栈了解不多。如果有人提供帮助，那就太好了。这是用于使用嵌套堆栈

注意：我可以毫无问题地创建三个堆栈。我唯一需要的是使用负载均衡器附加实例

Answer 1

您想做的是：

在您的负载均衡器堆栈中输出 ELB 资源 Ref
改为使用 AWS::AutoScaling::AutoScalingGroup 而不是 AWS::EC2::Instance。您可以利用 min/max/desired 来模拟单个实例行为。
在您的父堆栈中，将负载均衡器堆栈的输出作为参数传递给 EC2 堆栈，例如：LoadBalancerName: !GetAtt 'ElasticLoadBalancer.Outputs.LoadBalancerOutputName'
为 LoadBalancerNames 使用对参数 LoadBalancerName 的引用属性的 AWS::AutoScaling::AutoScalingGroup

使用 cloudformation 将嵌套堆栈创建的 ec2 实例附加到负载均衡器堆栈
