Multi Architecture

Building Multi-Architecture Images

To build an image for the default amd64 architecutre, no extra configuration is needed. For adding multiple architectures, add the additional_architectures field under the image configuration.

The following example will build the my-image for amd64 (default) and arm64.

base_images:
  os:
    name: ubi-minimal
    namespace: ocp
    tag: "9"
images:
- context_dir: .
  from: os
  to: my-image
  additional_architectures:
  - arm64

In the above example, the os image defined in the base_images is used as a base to build the my-image image. Since the additional_architectures is defined for arm64, the os image must be combatible with arm64 architecture too.

Running Tests on Different Architectures

To run tests on a specific architecture, add the node_architecture field to your test configuration:

tests:
- as: unit
  commands: make unit
  container:
    from: src
  node_architecture: arm64

This test uses src as a base image to run the unit test. Ci-operator will determine that the src image needs to be build for arm64 architecture will resolve the image build graph based on this information. Learn more about image lifecycle in #image-pipeline

Cluster selection

There is currently no need to configure a specific cluster to your test. Cluster selection is achieved via the prowjob dispatcher component. Based on the capabilities of the cluster, the correct selection will be done based on the job’s needs.
