Beginning right now, you need to use AWS CodeBuild Docker Server functionality to provision a devoted and chronic Docker server immediately inside your CodeBuild undertaking. With Docker Server functionality, you’ll be able to 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 decreased the whole 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 function from my AWS CodeBuild tasks.
AWS CodeBuild is a completely managed steady integration service that compiles supply code, runs assessments, and produces software program packages prepared for deployment. Constructing Docker pictures is without doubt one of the commonest use circumstances for CodeBuild prospects, and the service has progressively improved this expertise over time by releasing options comparable to Docker layer caching and reserved capability options to enhance Docker construct efficiency.
With the brand new Docker Server functionality, you’ll be able to cut back construct time in your functions by offering a persistent Docker server with constant caching. When enabled in a CodeBuild undertaking, 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 primarily based on the official AWS CodeBuild curated Docker pictures repository, particularly the Dockerfile for constructing a customary Ubuntu picture. This picture incorporates quite a few dependencies and instruments required for contemporary steady integration and steady supply (CI/CD) pipelines, making it a superb instance of the kind of massive Docker builds that growth groups commonly carry out.

This Dockerfile creates a complete construct atmosphere with a number of programming languages, construct instruments, and dependencies – precisely the kind of picture that may profit from persistent caching.
Within the construct specification (buildspec), I exploit 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 undertaking. I can even allow this functionality when enhancing current CodeBuild tasks.
I fill in all particulars and configuration. Within the Atmosphere part, I choose Further configuration.
Then, I scroll down and discover Docker server configuration and choose Allow docker server for this undertaking. Once I choose this selection, I can select a compute sort configuration for the Docker server. Once I’m completed with the configurations, I create this undertaking.
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 adjustments, the construct takes solely 16 seconds and that reveals 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 useful for giant, advanced Docker pictures with many layers. This demonstrates how Docker Server can dramatically enhance throughput for groups working quite a few Docker builds of their CI/CD pipelines.
Further issues to know
Listed here are a few issues to notice:
- Structure help – The function is on the market for each x86 (Linux) and ARM builds.
- Pricing – To study extra about pricing for Docker Server functionality, confer with the AWS CodeBuild pricing web page.
- Availability – This function is on the market in all AWS Areas the place AWS CodeBuild is obtainable. For extra details about the AWS Areas the place CodeBuild is on the market, see the AWS Areas web page.
You may study extra in regards to the Docker Server function within the AWS CodeBuild documentation.
