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 253 characters. The effect must be NoSchedule or PreferNoSchedule. Currently taint can only apply to node.
