AWS CodePipeline (CI/CD Pipeline)
CICD Pipeline with CodeCommit CodeBuild and CodeDeploy
Build stage with AWS CodeBuild
In a CI/CD pipeline, the build stage compiles source code, runs tests, and packages artifacts. AWS CodeBuild is a fully managed build service that integrates seamlessly with AWS CodePipeline, scaling on demand and only charging you for build minutes used.
Preconfigured Build Environments
AWS CodeBuild offers a rich set of managed images out of-the-box:
Runtime | Version Examples |
---|---|
Java | OpenJDK 8, Amazon Corretto 11 |
Ruby | MRI 2.7, 3.0 |
Go | 1.x |
Node.js | 12.x, 14.x, 16.x |
Android | SDK 29–31 |
.NET | Core 3.1, 5.0, 6.0 |
PHP | 7.4, 8.0 |
Docker | Docker Engine 20.10 |
Note
You can also supply a custom Docker image stored in Amazon ECR or a public registry to match your exact build requirements.
CodeBuild Workflow
When you trigger a build, CodeBuild orchestrates the following steps:
- Provision a temporary compute container based on your project settings.
- Initialize the specified runtime environment.
- Download your source code from the configured repository.
- Execute lifecycle commands defined in
buildspec.yml
. - Upload build artifacts to Amazon S3 or your chosen destination.
- Tear down the temporary container.
Here’s a sample buildspec.yml
:
version: 0.2
phases:
install:
commands:
- echo Installing dependencies...
- npm install
build:
commands:
- echo Running unit tests...
- npm test
- echo Building production bundle...
- npm run build
artifacts:
files:
- 'build/**/*'
discard-paths: yes
base-directory: build
Warning
Avoid printing sensitive values (API keys, secrets) directly in build logs. Use AWS Secrets Manager or Parameter Store and inject them as environment variables.
Monitoring and Notifications
CodeBuild integrates natively with Amazon CloudWatch and SNS:
Feature | AWS Service | Purpose |
---|---|---|
Logs & Metrics | Amazon CloudWatch Logs | Real-time logs, custom metrics |
Build Status Alerts | Amazon SNS | Email, SMS, HTTP endpoint alerts |
Event-Driven Triggers | CloudWatch Events | Automate downstream workflows |
Automatic Scaling
AWS CodeBuild automatically adjusts the number of build containers to match your concurrent jobs. There’s no provisioning or server management—just pay for the time your builds run.
Summary
AWS CodeBuild provides a robust, scalable build service within your CI/CD pipeline. Key takeaways:
- Fully managed continuous integration service
- Preconfigured runtimes or custom Docker images
- Deep integration: CodePipeline, CloudWatch, SNS, IAM, and more
- Automatic scaling with pay-as-you-go pricing
- Supports source from S3, CodeCommit, GitHub, Bitbucket, and others
- Ideal for replacing or complementing self-hosted solutions like Jenkins
Integration | AWS Service |
---|---|
Source Control | S3, CodeCommit, GitHub, Bitbucket |
Build Orchestration | AWS CodePipeline, CodeBuild |
Artifact Storage | Amazon S3 |
Logging & Metrics | Amazon CloudWatch Logs |
Notifications & Triggers | Amazon SNS, CloudWatch Events |
A hands-on demonstration—setting up a CodeBuild project, configuring a buildspec, and running your first build—will reinforce these concepts.
