KodeKloud Notes

Welcome to this lesson on AWS CodeBuild. In this module, we’ll explore how CodeBuild fits into the Build phase of your CI/CD pipeline, automating compilation, testing, and artifact generation. By integrating CodeBuild, you can achieve a fully managed, scalable build process that feeds seamlessly into Continuous Deployment.

The image illustrates a CI/CD pipeline with stages labeled Source, Build, Test, and Deploy, featuring AWS CodeBuild. It includes an infinity loop symbolizing continuous integration and delivery.

Why Choose AWS CodeBuild?

AWS CodeBuild is a serverless, fully managed build service that scales with your workload. Key advantages include:

Fully managed: No need to provision or maintain build servers.
Scalable: Run multiple builds in parallel without limits.
Secure: Leverage AWS IAM for permissions and AWS KMS for artifact encryption.

Note

You’re billed only for the compute minutes consumed by your builds, making CodeBuild cost-effective for fluctuating workloads.

Supported Source Repositories

CodeBuild integrates with popular source providers:

Resource Type	Link	Description
Amazon S3	https://aws.amazon.com/s3/	Store build inputs and outputs
AWS CodeCommit	https://aws.amazon.com/codecommit/	Managed Git repositories
GitHub	https://github.com	Public & private code hosting
Bitbucket	https://bitbucket.org	Atlassian’s Git platform

The image shows a DevOps CI/CD pipeline diagram with stages labeled Source, Build, Test, and Deploy, alongside icons for AWS Cloud services (Amazon S3, AWS CodeCommit) and third-party services (GitHub, Bitbucket).

Integrating or Replacing Jenkins

If you use Jenkins, you can either:

Replace Jenkins entirely with CodeBuild for an all-AWS solution.
Integrate Jenkins and CodeBuild by installing the AWS CodeBuild plugin, offloading build jobs to CodeBuild while maintaining existing pipelines.

Feature Comparison

Aspect	AWS CodeBuild	Jenkins
Hosting	Serverless, fully managed by AWS	Requires self-managed servers or agents
Scalability	Automatic, parallel builds	Manual scaling of worker nodes
Security	IAM roles & KMS encryption	Plugin-based or custom configuration
Ecosystem	Native AWS integrations	Large plugin ecosystem, external to AWS

The image shows a comparison between AWS CodeBuild and Jenkins, with AWS CodeBuild labeled as part of the AWS Cloud and Jenkins as a third-party tool.

That wraps up our high-level overview of AWS CodeBuild. In the next lesson, we’ll dive into:

Configuring CodeBuild projects
Writing and customizing buildspec.yml files
Optimizing build environments for performance
