AWS CodeBuild推出Docker Server功能，旨在通过在CodeBuild项目中配置专用且持久的Docker服务器，来加速Docker镜像的构建过程。该功能通过集中镜像构建到远程主机，显著减少了等待时间，提高了整体效率。经过测试，构建时间从24分钟54秒缩短至16秒，降幅高达98%。Docker Server通过提供具有一致缓存的持久Docker服务器来减少应用程序的构建时间。启用后，专用Docker服务器会配置持久存储，以维护Docker层缓存，从而处理多个并发Docker构建操作，所有构建都将从同一集中式缓存中受益。

🚀 AWS CodeBuild Docker Server通过提供持久的Docker服务器和集中的缓存，显著减少了Docker镜像的构建时间，经过测试，构建时间减少了98%。

⚙️ 启用Docker Server功能非常简单，只需在AWS CodeBuild控制台中选择“创建项目”，然后在“环境”部分的“其他配置”中，启用“为此项目启用Docker服务器”选项，并选择计算类型配置。

🐳 Docker Server支持x86（Linux）和ARM架构的构建，适用于所有提供AWS CodeBuild的AWS区域。详细的定价信息可以在AWS CodeBuild定价页面上找到。

💾 Docker Server通过维护构建之间的所有层，提供持久缓存，这对于具有许多层的大型复杂Docker镜像尤其有价值，显著提高了CI/CD管道中运行大量Docker构建的团队的吞吐量。

<section class="blog-post-content lb-rtxt"><table id="amazon-polly-audio-table"><tbody><tr><td id="amazon-polly-audio-tab"><p></p></td></tr></tbody></table><p>Starting today, you can use <a href="https://aws.amazon.com/codebuild/&quot;&gt;AWS CodeBuild</a> Docker Server capability to provision a dedicated and persistent Docker server directly within your CodeBuild project. With Docker Server capability, you can accelerate your Docker image builds by centralizing image building to a remote host, which reduces wait times and increases overall efficiency.</p><p>From my benchmark, with this Docker Server capability, I reduced the total building time by 98 percent, from 24 minutes and 54 seconds to 16 seconds. Here’s a quick look at this feature from my AWS CodeBuild projects.</p><p><img class="aligncenter size-full wp-image-95729 c4" src="https://d2908q01vomqb2.cloudfront.net/da4b9237bacccdf19c0760cab7aec4a8359010b0/2025/04/30/news-2025-codebuilddockerserver-rev-0.png&quot; alt="" width="2692" height="1035" /></p><p><a href="https://aws.amazon.com/codebuild/&quot;&gt;AWS CodeBuild</a> is a fully managed continuous integration service that compiles source code, runs tests, and produces software packages ready for deployment. Building Docker images is one of the most common use cases for CodeBuild customers, and the service has progressively improved this experience over time by releasing features such as <a href="https://docs.aws.amazon.com/codebuild/latest/userguide/build-caching.html&quot;&gt;Docker layer caching</a> and <a href="https://docs.aws.amazon.com/codebuild/latest/userguide/fleets.html&quot;&gt;reserved capacity features</a> to improve Docker build performance.</p><p>With the new Docker Server capability, you can reduce build time for your applications by providing a persistent Docker server with consistent caching. When enabled in a CodeBuild project, a dedicated Docker server is provisioned with persistent storage that maintains your Docker layer cache. This server can handle multiple concurrent Docker build operations, with all builds benefiting from the same centralized cache.</p><p><strong>Using AWS CodeBuild Docker Server</strong><br />Let me walk you through a demonstration that showcases the benefits with the new Docker Server capability.</p><p>For this demonstration, I’m building a complex, multi-layered Docker image based on the official <a href="https://github.com/aws/aws-codebuild-docker-images/tree/master&quot;&gt;AWS CodeBuild curated Docker images repository</a>, specifically the Dockerfile for building a <a href="https://github.com/aws/aws-codebuild-docker-images/tree/master/ubuntu/standard/5.0&quot;&gt;standard Ubuntu image</a>. This image contains numerous dependencies and tools required for modern continuous integration and continuous delivery (CI/CD) pipelines, making it a good example of the type of large Docker builds that development teams regularly perform.</p><pre class="language-dockerfile"># Copyright 2020-2024 Amazon.com, Inc. or its affiliates.

This is expected for the first build of such a complex image.</p><p><img class="aligncenter size-full wp-image-95732 c4" src="https://d2908q01vomqb2.cloudfront.net/da4b9237bacccdf19c0760cab7aec4a8359010b0/2025/04/30/news-2025-codebuilddockerserver-rev-3.png&quot; alt="" width="2708" height="2071" /></p><p>For subsequent builds with no code changes, the build takes only 16 seconds and that shows 98% reduction in build time.</p><p><img class="aligncenter size-full wp-image-95733 c4" src="https://d2908q01vomqb2.cloudfront.net/da4b9237bacccdf19c0760cab7aec4a8359010b0/2025/04/30/news-2025-codebuilddockerserver-rev-4.png&quot; alt="" width="2696" height="2080" /></p><p>Looking at the logs, I can see that with Docker Server, most layers are pulled from the persistent cache:</p><p><img class="aligncenter wp-image-95734 size-full c4" src="https://d2908q01vomqb2.cloudfront.net/da4b9237bacccdf19c0760cab7aec4a8359010b0/2025/04/30/news-2025-codebuilddockerserver-rev-5.png&quot; alt="" width="2664" height="2548" /></p><p>The persistent caching provided by the Docker Server maintains all layers between builds, which is particularly valuable for large, complex Docker images with many layers. This demonstrates how Docker Server can dramatically improve throughput for teams running numerous Docker builds in their CI/CD pipelines.</p><p><strong>Additional things to know</strong><br />Here are a couple of things to note:</p><ul><li><strong>Architecture support</strong> – The feature is available for both x86 (Linux) and ARM builds.</li><li><strong>Pricing</strong> – To learn more about pricing for Docker Server capability, refer to the <a href="https://aws.amazon.com/codebuild/pricing/&quot;&gt;AWS CodeBuild pricing</a> page.</li><li><strong>Availability</strong> – This feature is available in all AWS Regions where AWS CodeBuild is offered.
