Chapter 16. Installing a cluster with the support for configuring multi-architecture compute machines

Procedure

1. Check that the openshift-install binary is using the multi payload by running the following command:

   $ ./openshift-install version

   Example output

   ./openshift-install 4.17.0
   built from commit abc123etc
   release image quay.io/openshift-release-dev/ocp-release@sha256:abc123wxyzetc
   release architecture multi
   default architecture amd64

   The output must contain release architecture multi to indicate that the openshift-install binary is using the multi payload.

2. Update the install-config.yaml file to configure the architecture for the nodes.

   Sample install-config.yaml file with multi-architecture configuration

   apiVersion: v1
   baseDomain: example.openshift.com
   compute:
   - architecture: amd64 1
     hyperthreading: Enabled
     name: worker
     platform: {}
     replicas: 3
   controlPlane:
     architecture: arm64 2
     name: master
     platform: {}
     replicas: 3
   # ...

   1

   Specify the architecture of the worker node. You can set this field to either arm64 or amd64.

   2

   Specify the control plane node architecture. You can set this field to either arm64 or amd64.
