|
To create a cluster with multi-architecture compute machines on bare metal (`x86_64` or `aarch64`), {ibm-power-name} (`ppc64le`), or {ibm-z-name} (`s390x`) you must have an existing single-architecture cluster on one of these platforms. Follow the installations procedures for your platform:
|
|
|
|
* xref:../../installing/installing_bare_metal/upi/installing-bare-metal.adoc#installing-bare-metal[Installing a user provisioned cluster on bare metal]. You can then add 64-bit ARM compute machines to your {product-title} cluster on bare metal.
|
|
* xref:../../installing/installing_ibm_power/preparing-to-install-on-ibm-power.adoc#preparing-to-install-on-ibm-power[Installing a cluster on {ibm-power-name}]. You can then add `x86_64` compute machines to your {product-title} cluster on {ibm-power-name}.
|
|
* xref:../../installing/installing_ibm_z/preparing-to-install-on-ibm-z.adoc#preparing-to-install-on-ibm-z[Installing a cluster on {ibm-z-name} and {ibm-linuxone-name}]. You can then add `x86_64` compute machines to your {product-title} cluster on {ibm-z-name} and {ibm-linuxone-name}.

[IMPORTANT]
|
|
====
|
|
The bare metal installer-provisioned infrastructure and the Bare Metal Operator do not support adding secondary architecture nodes during the initial cluster setup. You can add secondary architecture nodes manually only after the initial cluster setup.
|
|
====
|
|
|
|
Before you can add additional compute nodes to your cluster, you must upgrade your cluster to one that uses the multi-architecture payload. For more information on migrating to the multi-architecture payload, see xref:../../updating/updating_a_cluster/migrating-to-multi-payload.adoc#migrating-to-multi-payload[Migrating to a cluster with multi-architecture compute machines].
|
|
|
|
The following procedures explain how to create a {op-system} compute machine using an ISO image or network PXE booting. This allows you to add additional nodes to your cluster and deploy a cluster with multi-architecture compute machines.
|
|
|
|
[NOTE]
|
|
====
|
|
Before adding a secondary architecture node to your cluster, it is recommended to install the Multiarch Tuning Operator, and deploy a `ClusterPodPlacementConfig` object. For more information, see xref:../../post_installation_configuration/configuring-multi-arch-compute-machines/multiarch-tuning-operator.adoc#multiarch-tuning-operator[Managing workloads on multi-architecture clusters by using the Multiarch Tuning Operator].
