NAME

kubectl get - Display one or many resources

SYNOPSIS

kubectl get [OPTIONS]

DESCRIPTION

Display one or many resources

Prints a table of the most important information about the specified resources. You can filter the list using a label selector and the --selector flag. If the desired resource type is namespaced you will only see results in your current namespace unless you pass --all-namespaces.

Uninitialized objects are not shown unless --include-uninitialized is passed.

By specifying the output as 'template' and providing a Go template as the value of the --template flag, you can filter the attributes of the fetched resources.

Use "kubectl api-resources" for a complete list of supported resources.

OPTIONS

-A, --all-namespaces=false If present, list the requested object(s) across all namespaces. Namespace in current context is ignored even if specified with --namespace.

--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.

--chunk-size=500 Return large lists in chunks rather than all at once. Pass 0 to disable. This flag is beta and may change in the future.

--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 get from a server.

--ignore-not-found=false If the requested object does not exist the command will return exit code 0.

-k, --kustomize="" Process the kustomization directory. This flag can't be used together with -f or -R.

-L, --label-columns=[] Accepts a comma separated list of labels that are going to be presented as columns. Names are case-sensitive. You can also use multiple flag options like -L label1 -L label2...

--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-watch-events=false Output watch event objects when --watch or --watch-only is used. Existing objects are output as initial ADDED events.

--raw="" Raw URI to request from the server. Uses the transport specified by the kubeconfig file.

-R, --recursive=false Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.

-l, --selector="" Selector (label query) to filter on, supports '=', '==', and '!='.(e.g. -l key1=value1,key2=value2)

--server-print=true If true, have the server return the appropriate table output. Supports extension APIs and CRDs.

--show-kind=false If present, list the resource type for the requested object(s).

--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].

--use-openapi-print-columns=false If true, use x-kubernetes-print-column metadata (if present) from the OpenAPI schema for displaying a resource.

-w, --watch=false After listing/getting the requested object, watch for changes. Uninitialized objects are excluded if no object name is provided.

--watch-only=false Watch for changes to the requested object(s), without listing/getting first.
