Trying to use journalctl to view logs but the output get's truncated or doesn't wrap around.  Using the following for me had best results in my case:

journalctl -xe -u kubelet.service -f

Other variations with slightly different results:

journalctl -xe -u kubelet.service -fn100

Another variant that can be usefull includes:

journalctl -xe -u kubelet.service | more

Likewise, the following:

journalctl -xe -u kubelet.service | less

Cheers,
