2.1.3.2. Creating & Configuring Artifact Repositories (CodeArtifact, S3, ECR)
First Principle: Centralized and securely configured artifact repositories are fundamental for consistent, reproducible, and auditable software delivery.
Artifact repositories are central storage locations for the various components produced during the software build process. Properly creating and configuring these repositories is essential for efficient and secure CI/CD.
Key AWS Artifact Repositories and Configuration:
- AWS CodeArtifact: (A fully managed artifact repository service that supports popular package managers like Maven, npm, pip, and NuGet.)
- Configuration: Create domains and repositories, configure upstream repositories (e.g., Maven Central), and set IAM permissions.
- Amazon S3 (Simple Storage Service): (A highly scalable object storage service often used for storing generic build artifacts, deployment packages, and static assets.)
- Configuration: Create S3 buckets, enable versioning, configure lifecycle policies for retention, and apply bucket policies for access control and encryption.
- Amazon Elastic Container Registry (ECR): (A fully managed Docker container registry for storing, managing, and deploying Docker container images.)
- Configuration: Create ECR repositories, configure lifecycle policies for image cleanup, and set repository policies for access control and image scanning.
Scenario: A DevOps team needs to set up secure, centralized repositories for their Java dependencies, Docker images, and final deployment artifacts. They want to ensure proper access control and automated cleanup of old versions.
Reflection Question: How would you configure AWS CodeArtifact, Amazon ECR, and Amazon S3 (with lifecycle policies and IAM policies) to establish a comprehensive and compliant artifact management system for this team?
Each service serves a specific type of artifact, and their correct configuration ensures secure, efficient, and compliant artifact management.
š” Tip: Use lifecycle policies in S3 and ECR to automatically clean up old or unused artifacts, helping to manage storage costs and maintain repository hygiene.
