Deleting a Namespace and all its Objects

Another handy feature of the Namespaces is their cascading effect. If, for example, we delete the testing Namespace, all the objects and the resources running inside it will be removed as well.

kubectl delete ns testing
    
kubectl -n testing get all  

We deleted the testing Namespace and retrieved all the objects residing in it. The output is as follows:

NAME                              READY STATUS      RESTARTS AGE
po/go-demo-2-api-56dfb69dbd-8w6rf 0/1   Terminating 0        2m
po/go-demo-2-api-56dfb69dbd-hrr4b 0/1   Terminating 0        2m
po/go-demo-2-api-56dfb69dbd-ws855 0/1   Terminating 0        2m
po/go-demo-2-db-5b49cc946b-xdd6v  0/1   Terminating 0        2m  

Please note that, in your case, the output might show more objects. If that's the case, you were too fast, and Kubernetes did not yet have time to remove them.
