To check the status of objects in a namespace use the following command:
$ kubectl --namespace <namespace> get nodes,pod,service,secret,pv,pvc,ingress -o wide
For example:
$ kubectl --namespace oidns get nodes,pod,service,secret,pv,pvc,ingress -o wide
Output will be similar to the following:

To view logs for a POD use the following command:
$ kubectl logs <pod> -n <namespace>
For example:
$ kubectl logs oidhost1 -n oidns
Output will depend on the application running in the POD.
Details about a POD can be viewed using the kubectl describe command:
$ kubectl describe pod <pod> -n <namespace>
For example:
$ kubectl describe pod oidhost1 -n oidns
Output will be similar to the following:
