在私有子网中设置 Redash 实例。 EC2 状态检查失败

Question

问题总结

我想在私有子网中设置 Redash 实例，但效果不佳。实例状态检查为“1/2 失败”。问题是除了网站介绍的设置外，是否还有一些必要的设置(https://redash.io/help/open-source/setup)。

供您参考，如果我将 redash 实例放在 public 子网上，它运行良好。

技术细节：

AMI：ami-060741a96307668be

EC2 大小：t2.small

私有子网有NAT网关

CloudFormation 模板如下。（我删除了参数，因为那些是机密信息。参数是正确的，因为我用 public 子网检查了这些参数。所以请检查其他部分，谢谢。）

根据 marcin 的评论，我尝试了下面的模板，但效果不佳，ec2 状态检查显示“1/2 失败”

我修改了模板，使其可以正常工作。我只能在我的沙盒帐户中的 us-east-1 中进行测试，因此我对该区域进行了更改。您需要进一步修改它，因为您的模板不完整，我不得不填写很多空白。

模板有效并提供实例（来自 curl）：

<div class="fixed-width-page">
  <div class="bg-white tiled">
    <h4 class="m-t-0">Welcome to Redash!</h4>
    <div>Before you can use your instance, you need to do a quick setup.</div>
