The “kubectl get all” command only returns a limited set of resources, namely: pods, services, daemon sets, deployments, replica sets, jobs, cronjobs, and stateful sets (not Ingress, Secrets, ConfigMap, CRD, etc.).
While there is a rationale for this, it is often the case we need to see all the resources and custom resources defined in a namespace.
The command below will return all the resources and custom resources defined in a Kubernetes namespace (1,2).
kubectl api-resources --verbs=list --namespaced -o name | xargs -n 1 kubectl get --show-kind --ignore-not-found -n <namespace>
