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 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-
Options
--all select all nodes in the cluster
--include-extended-apis If true, include definitions of new APIs via calls to the API server. [default true] (default true)
--no-headers When using the default or custom-column output format, don't print headers.
-o, --output string Output format. One of: json|yaml|wide|name|custom-columns=...|custom-columns-file=...|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See custom columns [http://kubernetes.io/docs/user-guide/kubectl-overview/#custom-columns], golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://kubernetes.io/docs/user-guide/jsonpath].
--output-version string Output the formatted object with the given group version (for ex: 'extensions/v1beta1').
--overwrite If true, allow taints to be overwritten, otherwise reject taint updates that overwrite existing taints.
--schema-cache-dir string If non-empty, load/store cached API schemas in this directory, default is '$HOME/.kube/schema' (default "~/.kube/schema")
-l, --selector string Selector (label query) to filter on
-a, --show-all When printing, show all resources (default hide terminated pods.)
--show-labels When printing, show all labels as the last column (default hide labels column)
--sort-by string If non-empty, sort list types using this field specification. The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string.
