Display one or many resources

Examples (TL;DR)

Eric Paris Jan 2015

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.

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, name, go-template, go-template-file, template, templatefile, jsonpath, jsonpath-as-json, jsonpath-file, custom-columns, custom-columns-file, wide). See custom columns [https://kubernetes.io/docs/reference/kubectl/#custom-columns], golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [https://kubernetes.io/docs/reference/kubectl/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). Matching objects must satisfy all of the specified label constraints.

--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)

--show-managed-fields=false If true, keep the managedFields when printing objects in JSON or YAML format.

--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.

--subresource="" If specified, gets the subresource of the requested object. Must be one of [status scale]. This flag is alpha and may change in the future.

--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.

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

Options Inherited from Parent Commands

--as="" Username to impersonate for the operation. User could be a regular user or a service account in a namespace.

--as-group=[] Group to impersonate for the operation, this flag can be repeated to specify multiple groups.

--as-uid="" UID to impersonate for the operation.

--azure-container-registry-config="" Path to the file containing Azure container registry configuration information.

--cache-dir="/builddir/.kube/cache" Default cache directory

--certificate-authority="" Path to a cert file for the certificate authority

--client-certificate="" Path to a client certificate file for TLS

--client-key="" Path to a client key file for TLS

--cluster="" The name of the kubeconfig cluster to use

--context="" The name of the kubeconfig context to use

--insecure-skip-tls-verify=false If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure

--kubeconfig="" Path to the kubeconfig file to use for CLI requests.

--match-server-version=false Require server version to match client version

-n, --namespace="" If present, the namespace scope for this CLI request

--password="" Password for basic authentication to the API server

--profile="none" Name of profile to capture. One of (none|cpu|heap|goroutine|threadcreate|block|mutex)

--profile-output="profile.pprof" Name of the file to write the profile to

--request-timeout="0" The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests.

-s, --server="" The address and port of the Kubernetes API server

--tls-server-name="" Server name to use for server certificate validation. If it is not provided, the hostname used to contact the server is used

--token="" Bearer token for authentication to the API server

--user="" The name of the kubeconfig user to use

--username="" Username for basic authentication to the API server

--version=false Print version information and quit

--warnings-as-errors=false Treat warnings received from the server as errors and exit with a non-zero exit code

Example

  # List all pods in ps output format
  kubectl get pods
  
  # List all pods in ps output format with more information (such as node name)
  kubectl get pods -o wide
  
  # List a single replication controller with specified NAME in ps output format
  kubectl get replicationcontroller web
  
  # List deployments in JSON output format, in the "v1" version of the "apps" API group
  kubectl get deployments.v1.apps -o json
  
  # List a single pod in JSON output format
  kubectl get -o json pod web-pod-13je7
  
  # List a pod identified by type and name specified in "pod.yaml" in JSON output format
  kubectl get -f pod.yaml -o json
  
  # List resources from a directory with kustomization.yaml - e.g. dir/kustomization.yaml
  kubectl get -k dir/
  
  # Return only the phase value of the specified pod
  kubectl get -o template pod/web-pod-13je7 --template={{.status.phase}}
  
  # List resource information in custom columns
  kubectl get pod test-pod -o custom-columns=CONTAINER:.spec.containers[0].name,IMAGE:.spec.containers[0].image
  
  # List all replication controllers and services together in ps output format
  kubectl get rc,services
  
  # List one or more resources by their type and names
  kubectl get rc/web service/frontend pods/web-pod-13je7
  
  # List status subresource for a single pod.
  kubectl get pod web-pod-13je7 --subresource status
