Step 1: Storing Docker Images in Amazon ECRDocker images can be large, and storing them in a centralized, scalable location can greatly reduce build times. Amazon Elastic Container Registry (ECR) is a fully managed container registry that stores, manages, and deploys Docker container images.
Action: Store the Docker images in an ECR repository.
Why: Storing Docker images in ECR ensures that Docker images can be reused across multiple builds, improving build performance by avoiding the need to rebuild the images from scratch.
[Reference: AWS documentation on Amazon ECR., Step 2: Implementing Docker Layer Caching in CodeBuildDocker layer caching is essential for improving performance in continuous integration pipelines. CodeBuild supports local caching of Docker layers, which speeds up builds that reuse Docker images across multiple runs., Action: Implement Docker layer caching within the CodeBuild project., Why: This improves performance by allowing frequently used Docker layers to be cached locally, avoiding the need to pull or build the layers every time., Reference: AWS documentation on Docker Layer Caching in CodeBuild., This corresponds to Option A: Store the Docker images in an Amazon Elastic Container Registry (Amazon ECR) repository. Implement a local Docker layer cache for CodeBuild., , , , ]
