AWS CodeBuild Docker Server

AWS CodeBuild has introduced a new Docker Server feature to accelerate Docker image builds in CI/CD pipelines

The Docker Server provides a dedicated, persistent Docker host within a CodeBuild project, maintaining Docker layer cache between builds

This feature significantly reduces build times by reusing cached layers, especially for repeated builds with minimal code changes

Benchmarks show up to a 98% reduction in build time, from nearly 25 minutes to just 16 seconds for subsequent builds

The persistent Docker server supports concurrent Docker build activities, leveraging a centralized cache for efficiency

The feature is enabled via the AWS CodeBuild console under Environment > Additional configuration > Docker server setup

Users can select compute type configurations for the Docker server to match their workload requirements

The Docker Server supports both ARM and x86 (Linux) architectures, broadening compatibility

The feature is ideal for organizations with frequent Docker builds in their CI/CD pipelines, boosting throughput and productivity
