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.

Syntax

werf kubectl taint NODE NAME KEY_1=VAL_1:TAINT_EFFECT_1 ... KEY_N=VAL_N:TAINT_EFFECT_N [options]

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-
  
  # 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

Options

            |jsonpath|jsonpath-as-json|jsonpath-file.
      --overwrite=false
            If true, allow taints to be overwritten, otherwise reject taint updates that overwrite  
            existing taints.

      --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
