我的目标是 尝试编写一个(单个)SAM 模板来获取由 Api 网关事件触发的 Lambda 函数。
我想要有多个 API 阶段(例如“dev”、“testing”、“prod”),并且希望每个阶段都映射到具有相同名称的 Lambda 别名。
我不想在每次部署时生成新的 lambda 版本,并且我喜欢手动设置每个 lambda 别名要使用的 lambda 版本。当然,“dev”别名意味着指向 $LATEST 代码版本。
我尝试了什么以及我得到了什么
我对经典的“hello_world”模板进行了如下修改。现在,当第一次部署(例如,“开发”)时,一切似乎都按预期工作。 但是,如果我尝试部署到“测试”阶段,则此新阶段的 API 会响应,而“开发”阶段的 API 将停止响应。
我缺少什么?

I had the same question as you, and found this: https://jun711.github.io/aws/deploy-api-gateway-to-multiple-stage-when-aws-sam-replaces-previous-stages/. It looks like SAM replaces the previous stages.
这位小伙子做了一些手动步骤来使其工作。很高兴知道它可以工作,但是有点破坏了“基础设施即代码”,我想我将使用 ansible 为不同的环境模板化不同版本的模板,然后运行它。
