kubectl annotate — Update the annotations on a resource

Synopsis

kubectl annotate [Options]

Description

Update the annotations on one or more resources.

0

item An annotation is a key/value pair that can hold larger (compared to a label), and possibly not human-readable, data.
item It is intended to store non-identifying auxiliary data, especially data manipulated by tools and system extensions.
item If --overwrite is true, then existing annotations can be overwritten, otherwise attempting to overwrite an annotation will result in an error.
item If --resource-version is specified, then updates will use this resource version, otherwise the existing resource-version will be used.

Valid resource types include:

0

item all
item certificatesigningrequests (aka 'csr')
item clusterrolebindings
item clusterroles

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.

-f, --filename=[]

Filename, directory, or URL to files identifying the resource to update the annotation

--include-extended-apis=true

If true, include definitions of new APIs via calls to the API server. [default true]

--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.

--local=false

If true, annotation will NOT contact api-server but run locally.

--no-headers=false

When using the default or custom-column output format, don't print headers (default print headers).

-o, --output=""

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=""

DEPRECATED: To use a specific API version, fully-qualify the resource, version, and group (for example: 'jobs.v1.batch/myjob').

--overwrite=false

If true, allow annotations to be overwritten, otherwise reject annotation updates that overwrite existing annotations.

--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 annotation 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).

-a, --show-all=false

When printing, show all resources (default hide terminated pods.)

--show-labels=false

When printing, show all labels as the last column (default hide labels column)

--sort-by=""

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.

--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⟩].
