Known issues:

When running...

kubectl logs -n $namespace --since=1h --timestamps --follow $podName

...at first, it won't attach giving this message:

Pod found: myservice-rc-74f69cd7c-8whq7                     0/1     ContainerCreating   0               5s
Watching logs for pod myservice-rc-74f69cd7c-8whq7 in namespace nnnnnnn...
Error from server (BadRequest): container "main" in pod "myservice-rc-74f69cd7c-8whq7" is waiting to start: ContainerCreating

...in which case you just repeat execting the command until the pod is no more in the "ContainerCreating" state. The script needs to be fixed to detect that situation and retry to attach.

Also, the namespace needs to be parametrized.
