SSH access to OSD/ROSA nodes

Solution Verified - Updated -

Environment

  • Red Hat OpenShift Service on AWS (ROSA)
    • 4
  • Red Hat OpenShift Dedicated (OSD)
    • 4
  • SSH

Issue

  • Is it possible to access with SSH to nodes in OSD/ROSA clusters?
  • How to access to nodes in OSD/ROSA using SSH.

Resolution

Currently, it's not possible to access via SSH to nodes in OSD/ROSA clusters. It is possible instead to access to the nodes using the following command:

oc debug node/<node_name>

If the "oc debug" command does not work and there is an issue related to a node, it is best to open a case with Red Hat to assist in resolving the issue.

Note that there is an RFE to allow enabling optional SSH access to worker nodes as an optional configuration (SDE-1283), but there is no ETA for this possible feature.

Root Cause

It's not possible to access via SSH to OSD/ROSA nodes.
