我将我们的AWS SAM部署包装在Jenkins中,作为CI / CD管道的一部分。例如,当我们合并时,我只想向lambda添加“活动”别名,但是我希望“分支构建”不包含别名。这使开发人员无需“实时”地在AWS中测试代码。除了在我运行“ sam package / deploy”之前用sed替换template.yaml的一部分之外,还有其他方法可以做到这一点吗?
-更新- 看起来我可以使用Parameters在lambda中创建环境,但是我不知道如何在它们之间切换。看起来像:
Parameters:
MyEnv:
Description: Environment of this stack of resources
Type: String
Default: testing
AllowedValues:
- testing
- prod
然后我可以引用此w /:
Environment:
Variables:
ENV: !Ref: MyEnv
如果有人知道如何在运行时切换此参数来解决我的问题。

我已经开始工作了。我的template.yaml:
AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: >
sams-app
Globals:
Function:
Timeout: 3
Parameters:
Stage:
Type: String
Description: Which stage the code is in
Default: test
AllowedValues:
- test
- prod
Resources:
HelloWorldSQSFunction:
Type: AWS::Serverless::Function
Properties:
Role: arn:aws:iam::xxxxxxxxxxxx:role/service_lambda_default1
CodeUri: hello_world/
Handler: app.lambda_handler
Runtime: python3.7
AutoPublishAlias: !Ref Stage
DeploymentPreference:
Type: AllAtOnce
Environment:
Variables:
STAGE: !Ref Stage
Outputs:
HelloWorldSQSFunction:
Description: "Hello World SQS Lambda Function ARN"
Value: !GetAtt HelloWorldSQSFunction.Arn
我的lambda代码:
import json
import os
def lambda_handler(event, context):
stage = os.environ['STAGE']
print(f"My stage is: {stage}")
return {
"statusCode": 200,
}
并在本地运行(我正在使用Cloud9):
DEVELOPER:~/environment/sams-app $ sam local invoke --parameter-overrides Stage=prod

要注意的一件事是,这将导致您的“ sam validate”失败。有关此信息,请参见:https://github.com/awslabs/serverless-application-model/issues/778
