oc adm taint — Update the taints on one or more nodes

Synopsis

oc adm taint [Options]

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  63 characters.

· The effect must be NoSchedule, PreferNoSchedule or NoExecute.

· Currently taint can only apply to node.
