AWS CodeBuild is a fully-managed continuous integration service that allows you to build, test, and deploy your code on the AWS cloud. It eliminates the need to maintain and manage build servers, so you can focus on developing your applications. CodeBuild scales automatically to meet your needs and supports many popular programming languages and frameworks.
To start using CodeBuild, you need to create a build project. A build project contains the information required to run a build, such as the source code, build specifications, build environment, and output artifacts. You can create a build project using the AWS Management Console or the AWS CLI.
First, choose the source code provider you want to use, such as Amazon S3, GitHub, or CodeCommit. Then, configure the build specifications, which are written in YAML format and define the build phases, environment variables, and output artifacts. You can customize the build environment with your own Docker images or use the pre-built ones provided by AWS.
Once you have created a build project, you can run a build manually or trigger it automatically using a webhook or a scheduled event. CodeBuild creates a temporary build environment in which it installs the required dependencies, downloads the source code, and runs the build phases defined in the build specifications.
You can monitor the progress of the build in the AWS Management Console or programmatically using the AWS SDK. CodeBuild also publishes the build logs to Amazon CloudWatch, allowing you to view and troubleshoot any issues that may occur during the build process.
CodeBuild integrates with many AWS services, such as AWS CodeDeploy, AWS CodePipeline, Amazon S3, AWS Lambda, and Amazon EC2 Container Service. You can use CodeBuild to create Docker images, deploy applications, and run tests as part of your continuous integration and delivery pipeline.
For example, you can use CodeBuild to build a Docker image and push it to Amazon ECR, which can then be deployed to Amazon ECS using AWS CodeDeploy. Or, you can use CodeBuild to run a test suite against your Lambda function and automatically trigger a rollback if the tests fail.
CodeBuild pricing is based on the build minutes consumed and the number of concurrent builds running at a given time. Standard build minutes and compute types are billed per minute, rounding up to the nearest minute. You can save costs by using spot instances and optimizing your build environment.
AWS CodeBuild makes it easy to automate your build and test processes on the AWS cloud. By eliminating the need to manage and maintain build servers, CodeBuild allows you to focus on developing and delivering high-quality software faster.
