How to SSH to worker nodes of openshift cluster on IBM cloud

Question

I have a openshift cluster on IBM cloud. I want to connect to the worker nodes using SSH via Putty but documentation says,

SSH by password is unavailable on the worker nodes.

Is there a way to connect to those?

Are you referring to this documentation? https://cloud.ibm.com/docs/openshift?topic=openshift-cs_troubleshoot_clusters#cs_ssh_worker It says how to tackle it — data_henrik, Oct 15 '20 at 05:39

If you use OpenShift v4 on IBM cloud, you may access your worker nodes using oc debug node/<target node name> instead of SSH. oc debug node command launches a temporary pod for the terminal session on the target node. You can check and run linux commands like usual SSH session through the Pod. Try it.

SSH access to worker nodes in OpenShift is disabled for security reasons. The documentation suggests to use DaemonSets for actions to be performed on worker nodes.
