Due to problems with automatic certificate renewal, the kubelet service may not be able to reach the Kubernetes API Server.
This issue is resolved in vRealize Automation (vRA) 8.1 P3 and vRealize Orchestrator (vRO) 8.1 P3 or later.
To workaround this issue, restart the kubelet service by performing the following: Open a console or SSH terminal to the vRA or vRO node.Run the command: 'systemctl restart kubelet'After 5 minutes, run the command 'vracli cluster exec -- bash -c 'current_node'' command to confirm the results. The host name of the current node should be printed successfully.
