Tolerating architecture taints in workloads

When a node or machine set has a taint, only workloads that tolerate that taint can be scheduled. You can configure your workload with a toleration so that it is scheduled on nodes with specific architecture taints.

Example deployment with toleration set

apiVersion: apps/v1
kind: Deployment
metadata: # ...
spec:
  # ...
  template:
    # ...
    spec:
      tolerations:
      - key: "multiarch.openshift.io/arch"
        value: "arm64"
        operator: "Equal"
        effect: "NoSchedule"

This example deployment can be scheduled on nodes and machine sets that have the multiarch.openshift.io/arch=arm64 taint specified.
