aws-codebuild-badges

Introduction

AWS CodeBuild already has badges for builds however this sample code is helpful to learn the basics of AWS Lambda, CodeBuild & CloudWatch. Adapted from jSherz's code

Setup AWS

1. Create S3 bucket
   • Make sure bucket has public access
   • e.g. bucket name: my-codebuild-badges
2. Create Lambda function
   • Pick Author from scratch
   • Name update-build-badges
   • Runtime Node.js 8.10
   • Role Create a custom role
   • On new page, View Policy Document > Edit

   {
        "Version": "2012-10-17",
        "Statement": [
            {
                "Effect": "Allow",
                "Action": [
                    "logs:CreateLogGroup",
                    "logs:CreateLogStream",
                    "logs:PutLogEvents"
                ],
                "Resource": "arn:aws:logs:*:*:*"
            },
            {
                "Sid": "AllowBadges",
                "Effect": "Allow",
                "Action": [
                    "s3:PutObject",
                    "s3:PutObjectAcl"
                ],
                "Resource": [
                    "arn:aws:s3:::my-codebuild-badges/*"
                ]
            }
        ]
    }

   • Go back to previous page after saving your custom role and click Create Function
   • If you would like to modify the code, check development section below otherwise download the latest version here
   • Upload code to your function and set environment variable BUCKET=my-codebuild-badges
3. Create CloudWatch event/trigger
   • Events > Rules > Create Rule
   • Service Name CodeBuild
   • Event Type CodeBuild Build State Change
   • Add target > Lambda function and select your lambda function
4. Trigger your build and you will see a new svg file under s3://my-codebuild-badges with your CodeBuild project name.

Development

Modify the code as you wish and create a zip bundle:

$ npm install
// modify the code
$ npm run zip

index.zip will be generated in project's root. This file can be uploaded to AWS Lambda.
