Field Selectors in k8s

Field Selector is a filtering primitive in k8s which allows users to filter k8s objects based on their resource-specific fields (unlike Label Selectors which query user-defined metadata, see Labels and Label Selectors in k8s):

• kubectl get pods --field-selector metadata.name=my-pod
• kubectl get pods --field-selector spec.nodeName=my-node

Important

Field Selector support varies depending on the resource type¹.
