Products

• VMware vSphere Kubernetes Service

Issue/Introduction

When enabling VKS, it returns error:

 

Environment

vCenter 8.x

vCenter 9.0

Cause

FLB( Foundation Load Balancer" doesn't work.  The network mode for workload network is configured as "DHCP",  FLB failed to get the DHCP IP address .

 

ssh to FLB, account name is 'vmware-system-user', the password can found when login to VM console (Launch a host UI of Esxi host, the VM console is inaccessible in vCenter).

 

Run command 'ifconfig' to check interfaces.

Resolution

When enabling VKS. there is a step to configure Workload network.

If user chooses 'DHCP', then user must prepare a DHCP server and a DNS Server&NTP Server, the deployment will fail if there is no DHCP Server .

To workaround it,  user has two options 

a) Choose 'Static', and provide static IP address.

b) Choose 'DHCP', and prepare a DHCP server and a DNS Server&NTP Server in advance.
