Overview
kubectl get ... --field-selector <expression>
--field-selector
specifies a selector (field query) to filter the result on. It supports the expressions containing '=', '==', and '!=', which can be applied to multiple fields.
--field-selector key1=value1,key2=value2,key3!=value3
The server only supports a limited number of field queries per each resource type. Supported fields vary per type. For example, attempting to query a PV for spec.claimRef.name
fails with:
Error from server (BadRequest): Unable to find "/v1, Resource=persistentvolumes" that match label selector "", field selector "spec.claimRef.name=something": "spec.claimRef.name" is not a known field selector: only "metadata.name", "metadata.namespace"
Note that you may be able to obtain the results expected from a field selector by using JSONPath filter expressions. For more details, see:
Supported Fields for Field Selectors
- PVs:
metadata.name
,metadata.namespace
.
Usage Examples
kubectl get pods --all-namespaces -o wide --field-selector spec.nodeName=<node>
