使用 CF 模板更新 AWS 堆棧

Question

希望大家注意安全！

我在 AWS Beanstalk 上托管了一個 Ruby on Rails 應用程序。 我正在使用 CloudFormation 模板來更新任何堆棧，例如 Ruby 版本、Linux 平台升級等。

我正在嘗試升級， Linux框到2.11.7和Ruby到2.6.6然后ElasticSearch到7.4

我在 CloudFormation YML 模板中進行了這些更改，然后我運行了aws cloudformation update-stack命令來應用這些更改。

雖然更改需要時間，但我不小心從 Web AWS 控制台單擊了Rebuild Environment ，結果，之前配置的所有設置，如SQS 、負載均衡器等，都被新設置替換了。

現在，每當我嘗試執行update-stack命令時，它都會失敗並出現以下錯誤：

我可以確認我設置了 Ruby-2.6.6。 我不確定它從哪里獲取舊版本的 Ruby？

有什么辦法可以解決這個問題嗎？ 或強制應用模板更改？

對此的任何幫助將不勝感激。

[更新]：當我嘗試從 Rails 控制台連接到 ElasticSearch 時，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)

elasticsearch 實例的新 URL 實例有所不同，但它仍然從ELASTICSEARCH_HOST ENV 變量中獲取舊的 URL。

來自我的 CF 模板的信息：

這是一個配置問題。

每當我運行aws update-stack命令時，它都會轉到 s3 並拉取 zip（源代碼）代碼，並在該 zip 代碼的 Gemfile 中將 ruby 版本設置為。

所以，我上傳了源代碼的新副本，然后執行了 update-stack 命令，它工作了
