kubectl set selector

Synopsis

Set the selector on a resource. Note that the new selector will overwrite the old selector if the resource had one prior to the invocation of ‘set selector’.

A selector must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores, up to 63 characters. If —resource-version is specified, then updates will use this resource version, otherwise the existing resource-version will be used. Note: currently selectors can only be set on Service objects.

  1. kubectl set selector (-f FILENAME | TYPE NAME) EXPRESSIONS [--resource-version=version]

Examples

  1.   # Set the labels and selector before creating a deployment/service pair
  2.   kubectl create service clusterip my-svc --clusterip="None" -o yaml --dry-run=client | kubectl set selector --local -f - 'environment=qa' -o yaml | kubectl create -f -
  3.   kubectl create deployment my-dep -o yaml --dry-run=client | kubectl label --local -f - environment=qa -o yaml | kubectl create -f -
