amazon web services - How to setup automated deployment from Code Commit to a Lambda Function?

Question

I'm trying to "deploy" the content of a CodeCommit repository to a Lambda function (not an application). In this particular case it's a simple copy/paste from source to destination.

I'm struggling to find a solution that doesn't involve setting up another lambda function. From what I understand, there is a solution using CodeBuild and CloudFormation.

Does anyone have a solution for this ? Alternatively, can you point to any good documentation ?

P.S:

I found this question on StackOverflow that seems to answer my question but the links in the relevant answer are outdated.

Answer 1

You can build a Code Commit Pipeline with a CodeBuild Job where you CodeCommit repository has a SAM Template like below and you run

sam build && sam deploy

From the codebuild job.

AWSTemplateFormatVersion : '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: A sample SAM template for deploying Lambda functions.

Resources:
# Details about the myDateTimeFunction Lambda function
  myDateTimeFunction:
    Type: AWS::Serverless::Function
    Properties:
      Handler: myDateTimeFunction.handler
      Runtime: nodejs12.x
# Creates an alias named "live" for the function, and automatically publishes when you update the function.
      AutoPublishAlias: live
      DeploymentPreference:
# Specifies the deployment configuration
          Type: Linear10PercentEvery2Minutes
