# kubectl-taint(1)

Update the taints on one or more nodes

Eric Paris Jan 2015

## NAME

kubectl taint - Update the taints on one or more nodes

## SYNOPSIS

**kubectl 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.

- •

  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.

## OPTIONS

**--all**=false\
 	Select all nodes in the cluster

**--allow-missing-template-keys**=true\
 	If true, ignore any errors in templates when a field or map key is missing in the template. Only applies to golang and jsonpath output formats.

**--dry-run**="none"\
 	Must be "none", "server", or "client". If client strategy, only print the object that would be sent, without sending it. If server strategy, submit server-side request without persisting the resource.

**--field-manager**="kubectl-taint"\
 	Name of the manager used to track field ownership.

**-o**, **--output**=""\
 	Output format. One of: (json, yaml, kyaml, name, go-template, go-template-file, template, templatefile, jsonpath, jsonpath-as-json, jsonpath-file).

**--overwrite**=false\
 	If true, allow taints to be overwritten, otherwise reject taint updates that overwrite existing taints.

**-l**, **--selector**=""\
 	Selector (label query) to filter on, supports '=', '==', '!=', 'in', 'notin'.(e.g. -l key1=value1,key2=value2,key3 in (value3)). Matching objects must satisfy all of the specified label constraints.

**--show-managed-fields**=false\
 	If true, keep the managedFields when printing objects in JSON or YAML format.

**--template**=""\
 	Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates \[http://golang.org/pkg/text/template/#pkg-overview\].

**--validate**="strict"\
 	Must be one of: strict (or true), warn, ignore (or false). "true" or "strict" will use a schema to validate the input and fail the request if invalid. It will perform server side validation if ServerSideFieldValidation is enabled on the api-server, but will fall back to less reliable client-side validation if not. "warn" will warn about unknown or duplicate fields without blocking the request if server-side field validation is enabled on the API server, and behave as "ignore" otherwise. "false" or "ignore" will not perform any schema validation, silently dropping any unknown or duplicate fields.

## OPTIONS INHERITED FROM PARENT COMMANDS

**--as**=""\
 	Username to impersonate for the operation. User could be a regular user or a service account in a namespace.

**--as-group**=\[\]\
 	Group to impersonate for the operation, this flag can be repeated to specify multiple groups.

**--as-uid**=""\
 	UID to impersonate for the operation.

**--as-user-extra**=\[\]\
 	User extras to impersonate for the operation, this flag can be repeated to specify multiple values for the same key.

**--cache-dir**="/home/username/.kube/cache"\
 	Default cache directory

**--certificate-authority**=""\
 	Path to a cert file for the certificate authority

**--client-certificate**=""\
 	Path to a client certificate file for TLS

**--client-key**=""\
 	Path to a client key file for TLS

**--cluster**=""\
 	The name of the kubeconfig cluster to use

**--context**=""\
 	The name of the kubeconfig context to use

**--disable-compression**=false\
 	If true, opt-out of response compression for all requests to the server

**--insecure-skip-tls-verify**=false\
 	If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure

**--kubeconfig**=""\
 	Path to the kubeconfig file to use for CLI requests.

**--kuberc**=""\
 	Path to the kuberc file to use for preferences. This can be disabled by exporting KUBECTL\_KUBERC=false feature gate or turning off the feature KUBERC=off.

**--match-server-version**=false\
 	Require server version to match client version

**-n**, **--namespace**=""\
 	If present, the namespace scope for this CLI request

**--password**=""\
 	Password for basic authentication to the API server

**--profile**="none"\
 	Name of profile to capture. One of (none\|cpu\|heap\|goroutine\|threadcreate\|block\|mutex\|trace)

**--profile-output**="profile.pprof"\
 	Name of the file to write the profile to

**--proxy-url**=""\
 	Proxy URL to use for requests to the API server

**--request-timeout**="0"\
 	The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests.

**-s**, **--server**=""\
 	The address and port of the Kubernetes API server

**--tls-server-name**=""\
 	Server name to use for server certificate validation. If it is not provided, the hostname used to contact the server is used

**--token**=""\
 	Bearer token for authentication to the API server

**--user**=""\
 	The name of the kubeconfig user to use

**--username**=""\
 	Username for basic authentication to the API server

**--version**=false\
 	\--version, --version=raw prints version information and quits; --version=vX.Y.Z... sets the reported version

**--warnings-as-errors**=false\
 	Treat warnings received from the server as errors and exit with a non-zero exit code

## EXAMPLE

```
  # 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
```
