Openshift connect to Nodes

Hi Folks,

I am slowly progressing with my Openshift course and one thing that I find supremely cool is the system they have for connecting to nodes in the cluster. @BertrandFR probably knows this since he works with Openshift :)

So instead of using ssh. you can simply run 

oc debug nodes/nodename

and openshift will run a privileged pod on that node which has access to the host file system, then creates a host directory in the root of the container in the pod, so you not only can inspect logs etc but chroot and run programs i.e. 

chroot /host

crictl ps

to see containers running on that node!

Of course the kubelet has to be running on the node so if you are having problems with that.. tough bananas.. back to ssh :)

Simple and highly effective.. no need for ssh!!
