= About node affinity rules for multi-architecture compute machines and Operator workloads
|
|
|
|
You must set node affinity rules to ensure your Operator workloads can run on multi-architecture compute machines. Node affinity is a set of rules used by the scheduler to define a pod's placement. Setting node affinity rules ensures your Operator's workloads are scheduled to compute machines with compatible architectures.
|
|
|
|
If your Operator performs better on particular architectures, you can set preferred node affinity rules to schedule pods to machines with the specified architectures.
|
|
|
|
For more information, see "About clusters with multi-architecture compute machines" and "Controlling pod placement on nodes using node affinity rules".
