About

• Code Build is responsible to build the application once the code changes are committed to VCS.

• Build instructions are present in buildspec.yml file.

• The file should be present in the root of the code or can manually upload in to the Management Console.

• Can use CloudWatch Metrics to monitor build statistics.

• EventBridge to detect failed builds and trigger notifications.

• CloudWatch Alarms to notify if you need thresholds for failures.

• Build Project can be defined within CodePipeline or CodeBuild.

• CodeBuild has supported environments for many languages. However, if a particular runtime is not supported Docker Image can be used.

Working

• CodeBuild uses a CodeBuild container to run the instructions written in buildspec.yml file.

• The container will spin up the supported runtime to build the code.

• CodeBuild uses a docker image to prepare the container.

• CodeBuild can cache to S3 the seldom changing reusable files required in builds.

• Output logs generated are stored in S3 and CloudWatch logs.

• Artifacts generated as a result of CodeBuild execution is saved to S3 bucket.

BuildSpec File

• BuildSpec reference has all details about different sections of file.

• Build Phase describe the phases in CodeBuild.
