LAB 3 - AWS CI CD - Setup a Build Project in AWS CodeBuild

This Lab has the step by step instructions to create & configure a Build using AWS  CodeBuild, which will compile latest commit of the pre-developed sample Java Application stored in AWS CodeCommit, generate the artifact and uploaded to the named S3 bucket.

Debugging CodeBuild

• AWS CodeBuild is a managed service, which uses pre-defined container images for handling builds. Hence you will not have access to the container images running your build.
• Local Build Support is enabled for AWS CodeBuild since May 2018, which you can use for debugging issues locally.
• Enabling Logging to CloudWatch or S3 is key to monitor the build progress from AWS Management Console and for debugging in case of failures
