VisualizaçõesHow to list really all objects of a nonexistant namespace?
Okay, the title is quite mouthful. But it's actually describing the situation.
I deployed a service on GKE in namespace argo-events. Something was wrong with it so I tore it down:
kubectl delete namespace argo-events
Actually, that's already where the problems started (I suspect a connection to the problem described below) and I had to resort to a hack because argo-events got stuck in a Terminating state forever. But the result was as desired - namespace seemed to be gone together with all objects in it.
Because of problems with redeployment I inspected the GKE Object Browser (just looking around - cannot filter for argo-events namespace anymore as it is officially gone) where I stumbled upon two lingering objects in ns argo-events:
argo-events is not listed by kubectl get namespaces. Just confirming that.
And I can find those two objects if I look them up specifically:
$ kubectl get eventbus -n argo-events
NAME AGE
default 17h
$ kubectl get eventsource -n argo-events
NAME AGE
pubsub-event-source 14h
But - I cannot find anything by asking for all objects:
$ kubectl get all -n argo-events
No resources found in argo-events namespace.
So my question is. How can I generically list all lingering objects in argo-events?
I'm asking because otherwise I'd have to inspect the entire Object Browser Tree to maybe find more objects (as I cannot select the namespace anymore).

By using command $ kubectl get all you will only print a few resources like:
- pod
- service
- daemonset
- deployment
- replicaset
- statefulset
- job
- cronjobs
It won't print all resources which can be found when you will use $ kubectl api-resources.
Example
When create PV from PersistentVolume documentation it won't be listed in $ kubectl get all output, but it will be listed if you will specify this resource.
$ kubectl apply -f https://raw.githubusercontent.com/kubernetes/website/master/content/en/examples/pods/storage/pv-volume.yaml
persistentvolume/task-pv-volume created
$ kubectl get pv
NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE
task-pv-volume 10Gi RWO Retain Available manual 3m12s
$ kubectl get all
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
service/kubernetes ClusterIP 10.3.240.1 <none> 443/TCP 86m
$
If you would like to list all resources from specific namespace you should use command below:
kubectl -n argo-events api-resources --namespaced=true -o name | xargs --verbose -I {} kubectl -n argo-events get {} --show-kind --ignore-not-found
Above solution was presented in Github thread kubectl get all does not list all resources in a namespace. In this thread you might find some additional variations of above command.
In addition, you can also check How to List all Resources in a Kubernetes Namespace article. You can find there method to list resources using function.
