## kubectl taint
|
|
|
|
Update the taints on one or more nodes
|
|
|
|
### Synopsis
|
|
|
|
|
|
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.
|
|
|
|
```
|
|
kubectl taint NODE NAME KEY_1=VAL_1:TAINT_EFFECT_1 ... KEY_N=VAL_N:TAINT_EFFECT_N
|
|
```
|
|
|
|
### Examples
|
|
|
|
```
|
|
# Update node 'foo' with a taint with key 'dedicated' and value 'special-user' and effect 'NoSchedule'.
|
|
# If a taint with that key already exists, its value and effect are replaced as specified.
|
|
kubectl taint nodes foo dedicated=special-user:NoSchedule
|
|
# Remove from node 'foo' the taint with key 'dedicated' if one exists.
|
|
kubectl taint nodes foo dedicated-
|
|
