Beginning in the present day, you should use AWS CodeBuild Docker Server functionality to provision a devoted and protracted Docker server straight inside your CodeBuild mission. With Docker Server functionality, you possibly can speed up your Docker picture builds by centralizing picture constructing to a distant host, which reduces wait instances and will increase general effectivity.
From my benchmark, with this Docker Server functionality, I lowered the full constructing time by 98 p.c, from 24 minutes and 54 seconds to 16 seconds. Right here’s a fast take a look at this characteristic from my AWS CodeBuild initiatives.
AWS CodeBuild is a totally managed steady integration service that compiles supply code, runs exams, and produces software program packages prepared for deployment. Constructing Docker photos is without doubt one of the most typical use instances for CodeBuild clients, and the service has progressively improved this expertise over time by releasing options equivalent to Docker layer caching and reserved capability options to enhance Docker construct efficiency.
With the brand new Docker Server functionality, you possibly can scale back construct time in your purposes by offering a persistent Docker server with constant caching. When enabled in a CodeBuild mission, a devoted Docker server is provisioned with persistent storage that maintains your Docker layer cache. This server can deal with a number of concurrent Docker construct operations, with all builds benefiting from the identical centralized cache.
Utilizing AWS CodeBuild Docker Server
Let me stroll you thru an indication that showcases the advantages with the brand new Docker Server functionality.
For this demonstration, I’m constructing a fancy, multi-layered Docker picture based mostly on the official AWS CodeBuild curated Docker photos repository, particularly the Dockerfile for constructing a customary Ubuntu picture. This picture accommodates quite a few dependencies and instruments required for contemporary steady integration and steady supply (CI/CD) pipelines, making it instance of the kind of giant Docker builds that improvement groups repeatedly carry out.

This Dockerfile creates a complete construct setting with a number of programming languages, construct instruments, and dependencies – precisely the kind of picture that will profit from persistent caching.
Within the construct specification (buildspec), I take advantage of the docker buildx construct . command:
model: 0.2
phases:
construct:
instructions:
- cd ubuntu/customary/5.0
- docker buildx construct -t codebuild-ubuntu:newest .
To allow the Docker Server functionality, I navigate to the AWS CodeBuild console and choose Create mission. I may allow this functionality when modifying current CodeBuild initiatives.
I fill in all particulars and configuration. Within the Setting part, I choose Extra configuration.
Then, I scroll down and discover Docker server configuration and choose Allow docker server for this mission. After I choose this feature, I can select a compute kind configuration for the Docker server. After I’m completed with the configurations, I create this mission.
Now, let’s see the Docker Server functionality in motion.
The preliminary construct takes roughly 24 minutes and 54 seconds to finish as a result of it must obtain and compile all dependencies from scratch. That is anticipated for the primary construct of such a fancy picture.
For subsequent builds with no code modifications, the construct takes solely 16 seconds and that exhibits 98% discount in construct time.
Trying on the logs, I can see that with Docker Server, most layers are pulled from the persistent cache:
The persistent caching supplied by the Docker Server maintains all layers between builds, which is especially worthwhile for big, complicated Docker photos with many layers. This demonstrates how Docker Server can dramatically enhance throughput for groups operating quite a few Docker builds of their CI/CD pipelines.
Extra issues to know
Listed here are a few issues to notice:
- Structure help – The characteristic is accessible for each x86 (Linux) and ARM builds.
- Pricing – To study extra about pricing for Docker Server functionality, discuss with the AWS CodeBuild pricing web page.
- Availability – This characteristic is accessible in all AWS Areas the place AWS CodeBuild is obtainable. For extra details about the AWS Areas the place CodeBuild is accessible, see the AWS Areas web page.
You possibly can study extra concerning the Docker Server characteristic within the AWS CodeBuild documentation.
