kubectl taint [page]deterministic

##

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. * Optionally, the key can begin with a DNS subdomain prefix and a single '/', like example.com/my-app. * The value is optional. If given, it 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.

``` kubectl taint NODE NAME KEY_1=VAL_1:TAINT_EFFECT_1 ... KEY_N=VAL_N:TAINT_EFFECT_N ```

``` # Update node 'foo' with a taint with key 'dedicated' and value 'special-user' and effect 'NoSchedule' # If a taint with that key and effect already exists, its value is replaced as specified kubectl taint nodes foo dedicated=special-user:NoSchedule # Remove from node 'foo' the taint with key 'dedicated' and effect 'NoSchedule' if one exists kubectl taint nodes foo dedicated:NoSchedule- # Remove from node 'foo' all the taints with key 'dedicated' kubectl taint nodes foo dedicated- # Add a taint with key 'dedicated' on nodes having label myLabel=X kubectl taint node -l myLabel=X dedicated=foo:PreferNoSchedule # Add to node 'foo' a taint with key 'bar' and no value kubectl taint nodes foo bar:NoSchedule ```
