Specialized nodes (e.g., with accelerators) can be Tainted to make sure unwanted pods are not scheduled on them. Tolerations can be set for the plugin pod to neutralize the Taint.
effect
string
Effect indicates the taint effect to match. Empty means match all taint effects.
When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute.
key
string
Key is the taint key that the toleration applies to. Empty means match all taint keys.
If the key is empty, operator must be Exists; this combination means to match all values and all keys.
operator
string
Operator represents a key's relationship to the value.
Valid operators are Exists and Equal. Defaults to Equal.
Exists is equivalent to wildcard for value, so that a pod can
tolerate all taints of a particular category.
tolerationSeconds
integer
TolerationSeconds represents the period of time the toleration (which must be
of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default,
it is not set, which means tolerate the taint forever (do not evict). Zero and
negative values will be treated as 0 (evict immediately) by the system.
format: int64
value
string
Value is the taint value the toleration matches to.
If the operator is Exists, the value should be empty, otherwise just a regular string.
