Taints allow a node to repel a set of pods, in opposite to Node Affinity

A taint consists of a key, value, and effect. As an argument here, it is expressed as key=value:effect. The effect must be NoSchedule, PreferNoSchedule or NoExecute.

taints:
   - key: eks.amazonaws.com/compute-type
     value: fargate
     effect: NoSchedule

spec:
  providerID: aws:///us-east-1a/i-085c2fcaaerterq
  taints:
    - key: dedicated
      value: gpuGroup
      effect: NoSchedule

     taints = {
       dedicated = {
         key    = "dedicated"
         value  = "gpuGroup"
         effect = "NO_SCHEDULE"
       }
     }
