Amazon Lambda

The two functions share the same deployment zip file (lambda.zip):

• authorizer
  • Runtime: Python 3.10
  • Handler: authorizer.authorizer
• api
  • Runtime: Python 3.10
  • Handler: api.api Different versions of the api Lambda function have assigned aliases dev, stage, prod. API Gateway reads the lambdaAlias variable uses its value as an alias, api:${stageVariables.lambdaAlias} to call a corresponding version of the api Lambda function.

Build the deployment zip file:

./scripts/build.sh

Update Lambda function code:

./scripts/deploy.sh {update_code|publish_version} {api|authorizer} [dev]
