Overview

Namespace Selection

Generic oc namespace selection applies.

Additionally, to specify all projects, use:

oc get --all-namespaces ...

Selectors

Selectors can be applied with the "-l" option:

oc get ... -l 'label_name=label_value'

To get (almost) all object with a specific label from the current project, execute:

oc get all -l '<label_name>=<label_value>'

Objects that are not displayed:

JSON Output

oc get ... -o json

JSONPath Output

oc get ... -o jsonpath='{.spec.replicas}'

YAML Output

oc get ... -o yaml

-o template, --template

oc get --template '{{.spec.volumeName}}{{"\n"}}' pvc/<pvc-name>
oc get --template '{{.status.podIP}}{{"\n"}}' pods/<pod-name>

Example:

oc get node infranode1 --template '{{.spec.externalID}}{{"\n"}}'
infranode1
