NAMEoc label − Update the labels on a resource

SYNOPSISoc label [OPTIONS]

DESCRIPTIONUpdate the labels on one or more resources A valid label value is consisted of letters and/or numbers with a max length of 63 characters. If −−overwrite is true, then existing labels can be overwritten, otherwise attempting to overwrite a label will result in an error. If −−resource−version is specified, then updates will use this resource version, otherwise the existing resource−version will be used.

OPTIONS−−all=false
Select all resources, including uninitialized ones, in the namespace of the specified resource types −−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=false
If true, only print the object that would be sent, without sending it. −−field−selector=""
Selector (field query) to filter on, supports '=', '==', and '!='.(e.g. −−field−selector key1=value1,key2=value2). The server only supports a limited number of field queries per type. −f, −−filename=[]
Filename, directory, or URL to files identifying the resource to update the labels −−include−uninitialized=false
If true, the kubectl command applies to uninitialized objects. If explicitly set to false, this flag overrides other flags that make the kubectl commands apply to uninitialized objects, e.g., "−−all". Objects with empty metadata.initializers are regarded as initialized. −−list=false
If true, display the labels for a given resource. −−local=false
If true, label will NOT contact api−server but run locally. −o, −−output=""
Output format. One of: json|yaml|name|go−template−file|templatefile|template|go−template|jsonpath|jsonpath−file. −−overwrite=false
If true, allow labels to be overwritten, otherwise reject label updates that overwrite existing labels. −−record=false
Record current kubectl command in the resource annotation. If set to false, do not record the command. If set to true, record the command. If not set, default to updating the existing annotation value only if one already exists. −R, −−recursive=false
Process the directory used in −f, −−filename recursively. Useful when you want to manage related manifests organized within the same directory. −−resource−version=""
If non−empty, the labels update will only succeed if this is the current resource−version for the object. Only valid when specifying a single resource. −l, −−selector=""
Selector (label query) to filter on, not including uninitialized ones, supports '=', '==', and '!='.(e.g. −l key1=value1,key2=value2). −−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⟩].

OPTIONS INHERITED FROM PARENT COMMANDS−−allow\_verification\_with\_non\_compliant\_keys\fP=false
Allow a SignatureVerifier to use keys which are technically non−compliant with RFC6962. −−alsologtostderr=false

Path to the file containing Azure container registry configuration information. −−boot\_id\_file\fP="/proc/sys/kernel/random/boot\_id"
Comma−separated list of files to check for boot−id. Use the first one that exists. −−cache−dir="/builddir/.kube/http−cache"

The name of the kubeconfig context to use −−default−not−ready−toleration−seconds=300
Indicates the tolerationSeconds of the toleration for notReady:NoExecute that is added by default to every pod that does not already have such a toleration. −−default−unreachable−toleration−seconds=300
Indicates the tolerationSeconds of the toleration for unreachable:NoExecute that is added by default to every pod that does not already have such a toleration. −−docker="unix:///var/run/docker.sock"
