AWS CodeBuild: Full Guide

AWS CodeBuild is a fully managed continuous integration service that compiles source code, runs tests, and produces software packages that are ready to deploy. It is an important service for developers as it automates the build process, saving time and effort.

What is AWS CodeBuild?
AWS CodeBuild is a service that compiles source code, runs tests, and produces deployable software packages. It eliminates the need to provision, manage, and scale your own build servers. CodeBuild scales continuously and processes multiple builds concurrently, so your builds are not left waiting in a queue.

How AWS CodeBuild Works:
1. You create a build project that defines how CodeBuild will run a build.
2. CodeBuild uses a build project to convert your source code into deployable artifacts.
3. A build environment represents a combination of operating system, programming language runtime, and tools that CodeBuild uses to run a build.
4. CodeBuild executes your build in a series of build phases that you define in the buildspec file.
