Flags
| Name | Shorthand | Default | Usage |
|---|---|---|---|
| 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. | |
| experimental-use-openapi-print-columns | false | If true, use x-kubernetes-print-column metadata (if present) from openapi schema for displaying a resource. | |
| export | false | If true, use 'export' for the resources. Exported resources are stripped of cluster-specific information. | |
| filename | f | [] | Filename, directory, or URL to files identifying the resource to get from a server. |
| ignore-not-found | false | Treat "resource not found" as a successful retrieval. | |
| include-extended-apis | true | If true, include definitions of new APIs via calls to the API server. [default true] | |
| label-columns | L | [] | 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). | |
| output | o | 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'). | ||
| raw | Raw URI to request from the server. Uses the transport specified by the kubeconfig file. | ||
| recursive | R | false | Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory. |
| schema-cache-dir | ~/.kube/schema | If non-empty, load/store cached API schemas in this directory, default is '$HOME/.kube/schema' | |
| selector | l | Selector (label query) to filter on, supports '=', '==', and '!='. | |
| show-all | a | false | When printing, show all resources (default hide terminated pods.) |
| 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]. | ||
| watch | w | false | After listing/getting the requested object, watch for changes. |
| watch-only | false | Watch for changes to the requested object(s), without listing/getting first. |
