I am trying to run kubelet on an Ubuntu machine using rkt and kubelet-wrapper. But doesn't seem to join the cluster. Even though the systemd unit is running, it never starts the actual kubelet. I want to know if what I am trying even possible? If yes, any help will be appreciated.

Thanks,
Jatan Ajmera

It should be possible. What are you seeing?

 systemd[1]: Started kubelet.service.
 kubelet-wrapper[15589]: RKT_OPTS environment variable is deprecated, please use the RKT_RUN_ARGS instead
 kubelet-wrapper[15589]: + exec /usr/bin/rkt run --volume dns,kind=host,source=/etc/resolv.conf --set-env-file=/etc/environment --mount volume=dns,target=/etc/resolv.conf
 kubelet-wrapper[15589]: ni-conf-dir=/etc/kubernetes/cni/net.d --cni-bin-dir=/opt/cni/bin --network-plugin=cni --container-runtime=docker --rkt-path=/usr/bin/rkt --rkt-sta

This is all I see in the journalctl logs. So it never actually ends up starting the kubelet. I checked rkt and it seems to be running the hyperkube container.
