GKE now supports opting out of the default kubernetes.io/arch=arm64:NoSchedule taint on Arm nodes in Standard node pools and in custom ComputeClasses. To opt out of the default taint, set the --node-architecture-taint-behavior gcloud CLI flag to NONE for a node pool or set the taintConfig.architectureTaintBehavior field to NONE for a ComputeClass. By configuring this behavior, you allow workloads that lack explicit Arm tolerations to be scheduled on Arm-based machine families (such as N4A and C4A). This is useful for running multi-architecture workloads or simplifying scheduling in mixed-mode clusters. For more information, see Configure the default Arm architecture taint.
