【问题描述】：
希望大家注意安全！
我有一个托管在 AWS Beanstalk 上的 Ruby on Rails 应用程序。我正在使用 CloudFormation 模板来更新任何堆栈，例如 Ruby 版本、Linux 平台升级等。
我正在尝试升级，Linux 框升级到 2.11.7，Ruby 升级到 2.6.6，然后 ElasticSearch 升级到 7.4
我在 CloudFormation YML 模板中进行这些更改，然后我运行 aws cloudformation update-stack 命令来应用这些更改。
虽然更改需要时间，但我不小心点击了 Web AWS 控制台中的 重建环境，所有之前配置的设置，如 SQS、负载均衡器 等，已被新设置取代。
现在，每当我尝试执行 update-stack 命令时，它都会失败并出现以下错误：

我可以确认我设置了 Ruby-2.6.6。我不确定它是从哪里获取旧版 Ruby 的？
有什么办法可以解决这个问题吗？或强制应用模板更改？
对此的任何帮助将不胜感激。
[更新]：当我尝试从 Rails 控制台连接到 ElasticSearch 时，我得到：
Faraday::ConnectionFailed: Failed to open TCP connection to old-elasticsearch-host-name.es.amazonaws.com:80 (Hostname not known: old-elasticsearch-host-name.es.amazonaws.com)
from /opt/rubies/ruby-2.6.6/lib/ruby/2.6.0/net/http.rb:949:in `rescue in block in connect'

elasticsearch 实例的新 URL 不同，但它仍然从ELASTICSEARCH_HOST ENV 变量中获取旧 URL。
来自我的 CF 模板的信息：
我现在可以根据要求提供信息。请标记我以查看我在 CF 模板中的内容
【问题讨论】：
-
我想知道 AWS Beanstalk 是否由 CloudFormation 管理。也许你可以分享你的模板？
-
您的堆栈更新现在处于什么状态？
-
@Marcin 你的意思是？从 AWS 控制台，我的 web 和 worker env 都处于红色状态
-
我的意思是 CloudFormation 堆栈。我了解您在堆栈中进行了一些更新，但同时您在 cloudformio 堆栈之外修改了资源？所以堆栈更新失败了？
-
@Marcin 是的，我在堆栈中做了一些更新，执行了 CF update-stack 命令，然后我重建了环境（这是我在 CF 堆栈之外进行的，即从 AWS 控制台）和从这一步开始，每次我尝试运行 update-stack 命令时都会失败
