amazon-web-services - S3静态网站/蓝绿部署

Question

我很难为我的 s3 静态网站提供蓝绿色。我在给定的存储桶中发布了该网站的一个版本，并在以下位置公开:

Cloudfront 发行版

然后在 53 号公路

和另一个 CDN(公司，解析 DNS)以访问互联网。

我尝试了一些“计算”解决方案，比如 ALB，但我没有成功。

我遇到的困难的主要问题是，当我使用新地址更新 CloudFront 时，DNS 复制时间很长，这使得将 future 版本回滚到旧版本变得困难(考虑为此发布使用不同的存储桶)。

有没有人经历过这个或知道如何解决这个问题？

AWS 建议您为每个创建不同的 CloudFront 分配
蓝/绿变体，每个都有自己的 DNS。
来自 Hosting Static Websites on AWS规范性指导:

Different CloudFront distributions can point to the same Amazon S3bucket so there is no need to have multiple S3 buckets. Each variation[A/B or blue/green] would store its assets under different folders in the same S3 bucket.Configure the CloudFront behaviors to point to the respective AmazonS3 folders for each A/B or blue/green variation.

The other key part of this strategy is an Amazon Route 53 featurecalled weighted routing. Weighted routing allows you to associatemultiple resources with a single DNS name and dynamically resolve DNSbased on their relative assigned weights. So if you want to split yourtraffic 70/30 for an A/B test, set the relative weights to be 70 and30. For blue/green deployments, an automation script can call the Amazon Route 53 API to gradually shift the relative weights from blueto green after automated tests validate that the green version ishealthy.
