aws-lambda - aws sam 发布/部署流程

Question

我没有完全掌握与 sam 一起发布/部署的流程。我最大的问题是我的 sam 模板声明了一个 AWS::Serverless::Function并且 CodeUri 参数强制我放入一个 s3 存储桶 url。

我见过一些示例，其中 CodeUri 只是您计算机上代码资源的路径。当我尝试这个时，山姆提示

'CodeUri' is not a valid S3 Uri of the form "s3://bucket/key" with optional versionId query parameter.

为了解决这个问题，我必须

将我的函数的 CodeUri 更改为模板中代码的根文件夹

进入AWS控制台，删除我s3桶中的资源，否则sam包不会上传

运行 sam 包上传我更新的代码资源

复制新的 s3 资源 key

回到我的模板并用新的 s3 存储桶 uri 替换 CodeUri

运行 sam 部署

这是非常令人讨厌的。

我错过了什么？

TemporaryFix 的评论是对此的正确答案。 AWS SAM 将工件正确上传到 s3，然后生成更新的模板文件。您需要指定 --template-output-path packaged.yaml运行时 sam package ，然后此命令将生成文件，其中包含对您的函数的 s3 存储桶的引用。然后您必须指定 --template-file packaged.yaml运行 deploy command 时

就像是:

sam build

sam package --s3-bucket your-bucket --output-template-file packaged.yaml

sam deploy --template-file packaged.yaml \
--region eu-west-1 \
--capabilities CAPABILITY_IAM \
--stack-name your-stack
