Management cluster VIP address not accessible through SSH

Products

• VMware Telco Cloud Automation

Issue/Introduction

Control plane node VMs in the cluster do not have a VIP address assigned. 

Environment

3.2

Cause

The IP address of the management cluster's control plane nodes is embedded in the etcd certificate. If the IP address of the control plane node changes, etcd will fail to start because the certificate no longer matches the new IP.

Resolution

1. For each control plane node, confirm the IP address in the etcd.yaml
   cat /etc/kubernetes/manifest/etcd.yaml
2. For each control plane node, adjust the DHCP lease, or statically assign the IP address
   vi /etc/systemd/networkd/10-cloud.x.yaml
3. Restart the control plane node vm
