name: taint
synopsis: Update the taints on one or more nodes
description: |-
  Update the taints on one or more nodes.

  A taint consists of a key, value, and effect. As an argument here, it is expressed as key=value:effect.
  The key must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores, up to 253 characters.
  The value must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores, up to 253 characters.
  The effect must be NoSchedule or PreferNoSchedule.
  Currently taint can only apply to node.
