| [root@k8s-master ~]# k8ctl get nodes --help
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.
Examples:
# 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
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].
-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.
Usage:
kubectl get
[(-o|--output=)json|yaml|wide|custom-columns=...|custom-columns-file=...|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=...]
(TYPE[.VERSION][.GROUP] [NAME | -l label] | TYPE[.VERSION][.GROUP]/NAME ...) [flags] [options]
Use "kubectl options" for a list of global command-line options (applies to all commands).
