openshift admin taint — Update the taints on one or more nodes

Synopsis

openshift admin 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.

Options
