AWS CodeBuild
AWS CodeBuild is a cloud service for automating software builds.
What AWS CodeBuild is
AWS CodeBuild is a cloud service for automating software builds. It runs scripts to compile, test, and package code, while managing and scaling the build capacity instead of requiring users to provision build servers. Projects can use prepared environments for Java, Python, Node.js, Ruby, Go, Android, .NET Core for Linux, and Docker, or bring a Docker-based environment. A YAML build specification sets commands for each build phase and other build settings. Builds can start from CodeCommit, GitHub, GitHub Enterprise, Bitbucket, Amazon S3, or CodePipeline. CodeBuild can also work with Jenkins and CodePipeline; CodeDeploy and Elastic Beanstalk are options in CodePipeline delivery workflows. Artifacts can be stored in S3 or sent to an artifact repository by a build command. The service reports build timing, status, and commit ID, and streams metrics and logs to CloudWatch. It integrates with IAM controls and KMS encryption, and SNS can notify users about project events. A free plan is listed, with paid usage based on compute and duration; additional AWS service and data-transfer charges may apply.
Good
- Build capacity scales without managing build servers.
- Supports a range of prepared programming environments.
- Builds can start from several listed source providers.
- CloudWatch receives build metrics and logs.
- Artifacts can be encrypted with KMS keys.
Watch out
- Paid compute is billed by build duration.
- Additional data-transfer and AWS service charges may apply.
- Reserved EC2 instances have a 60-minute minimum charge.
- Build timing rounds up to minutes on EC2.
Who it suits
CodeBuild suits teams that want managed build capacity for automated CI/CD pipelines, existing Jenkins jobs, or code hosted on GitHub. It also fits projects using its listed build environments or custom Docker-based environments.
Verdict
AWS CodeBuild handles build execution and capacity management while connecting to multiple source and delivery services. Review its usage-based compute charges, billing increments, and possible additional AWS charges before choosing it.
