Kubernetes | kubectl get
  1. kubectl get
  2. Usage
  3. Options
  4. Examples

  1. kubectl get
    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.

    To list kubectl get supported resources, type: kubectl api-resources

    To list kubectl get options, type: kubectl get --help

    To print the list of kubectl global command-line options (applies to all commands), type: kubectl options
  2. Usage
    Usage: kubectl get [(-o|--output=) format] (TYPE[.VERSION][.GROUP] [NAME | -l label] | TYPE[.VERSION][.GROUP]/NAME ...) [flags] [options]
  3. 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.
    
    -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].
    
        --no-headers=false
        When using the default or custom-column output format, don't print headers (default print headers).
    
        --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...
    
        --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].
    
    -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.
  4. Examples
    List all pods:
    kubectl get pods
    List all pods with more information (such as ip address, node name, ...):
    kubectl get pods -o wide
    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 deployments in JSON output format, in the "v1" version of the "apps" API group:
    kubectl get deployments.v1.apps -o json
    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 pods and services together:
    kubectl get pods,services
    List one or more resources by their types and names:
    kubectl get pods/web-pod-13je7 service/frontend
