Raw

Prints raw cluster information

TL;DR

  • Get or List Raw Resources in a cluster as Yaml or Json

Print Raw Resource

Motivation

Inspecting or Debugging Resources.

The Kubernetes Resources stored in etcd by the apiserver have many more fields than are shown in the summarized views. Users can learn much more about a Resource by viewing the Raw Resource as Yaml or Json. The Raw Resource will contain:

  • fields specified by the user in the Resource Config (e.g. metadata.name)
  • metadata fields owned by the apiserver (e.g. metadata.creationTimestamp)
  • fields defaulted by the apiserver (e.g. spec..imagePullPolicy)
  • fields set by Controllers (e.g. spec.clusterIp, status)

Get

The kubectl get reads Resources from the cluster and formats them as output. The examples in this chapter will query for Resources by providing Get the Resource Type as an argument. For more query options see Queries and Options.

YAML

Print the Raw Resource formatting it as YAML.
