kubectl describe

Synopsis

Show details of a specific resource or group of resources.

Print a detailed description of the selected resources, including related resources such as events or controllers. You may select a single object by name, all objects of that type, provide a name prefix, or label selector. For example:

  1.     $ kubectl describe TYPE NAME_PREFIX

will first check for an exact match on TYPE and NAME_PREFIX. If no such resource exists, it will output details for every resource that has a name prefixed with NAME_PREFIX.

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

  1. kubectl describe (-f FILENAME | TYPE [NAME_PREFIX | -l label] | TYPE/NAME)

Examples

  1.   # Describe a node
  2.   kubectl describe nodes kubernetes-node-emt8.c.myproject.internal
  4.   # Describe a pod
  5.   kubectl describe pods/nginx
  7.   # Describe a pod identified by type and name in "pod.json"
  8.   kubectl describe -f pod.json
  10.   # Describe all pods
  11.   kubectl describe pods
  13.   # Describe pods by label name=myLabel
  14.   kubectl describe pods -l name=myLabel
  16.   # Describe all pods managed by the 'frontend' replication controller
  17.   # (rc-created pods get the name of the rc as a prefix in the pod name)
  18.   kubectl describe pods frontend
