Testing an Intel and Arm multi-architecture Docker image on CircleCI

This is the fourth article about my adventures trying to use my Apple M1 MacBook for development. In the previous article, I described how to configure a CircleCI-based CI/CD pipeline to build a multi-architecture image and push it to a remote repository. The image supports both Intel and ARM architectures. However, the pipeline only tests the image on Intel. In this article, I describe how to configure the pipeline to also test the Docker image on other architectures.

The other articles in this series are:

Configuring the pipeline to test on Arm

By default, CircleCI jobs run on an Intel platform. However, CirclCI also supports the ARM platform. You can create an Arm-based job as follows:

    image: ubuntu-2004:202101-01
    resource_class: arm.medium

The resource_class attribute specifies the ARM resource.

We can configure the pipeline to execute the test-arm64 job after the build job with the following workflow configuration:

  version: 2.1
      - build
      - test-arm64:
            - build

Extracting a test script from

The testing logic needed by the test-arm64 job is currently embedded within The solution is to split that script into two: and The build job runs both of these scripts. The test-arm64 job runs just the test script:

    image: ubuntu-2004:202101-01
    resource_class: arm.medium
  working_directory: ~/plantuml
    - checkout
    - run: ./

After making these changes the CircleCI pipeline performs the following steps:

  1. Builds, pushes and tests (on Intel) the multi-architecture image
  2. Builds, tests and pushes the original Docker image
  3. Tests the multi-architecture image on Arm

We are now one step closer to a complete pipeline that builds, tests and publishes a multi-architecture Docker image. In the next article, I reconfigure the pipeline to eliminate the original single architecture image and publish the tested multi-architecture image to Docker Hub.

Virtual bootcamp: Distributed data patterns in a microservice architecture

My virtual bootcamp, distributed data patterns in a microservice architecture, is now open for enrollment!

It covers the key distributed data management patterns including Saga, API Composition, and CQRS.

It consists of video lectures, code labs, and a weekly ask-me-anything video conference repeated in multiple timezones.

The regular price is $395/person but use coupon KQAWEXBH to sign up for $120 (valid until November 21st, 2023). There are deeper discounts for buying multiple seats.
