📝 Can get more information about the field nodeName for a Pod specification?

Access the API natively without having to fiddle with authentication

kubectl proxy
curl http://localhost:8001/
curl http://localhost:8001/api/v1/pods

Check out the OpenAPI spec of your cluster

curl http://localhost:8001/openapi/v2

Can load it into any OpenAPI browser like https://editor.swagger.io/ (might be slow, does not allow mixing http/https so go via file)

curl http://localhost:8001/openapi/v2 -o k8s-api.yaml
