OpenShift Bootstrap node not obtaining API Virtual IP

Jump to solution
 

Hi, I'm installing OCP 4.13 on VMWare 8 using Assisted Installer.

I checked bot static and DHCP based setup but in the both cases the Boostrap node does not receive the API VIP (Virtual API).

My setup:

Network 10.34.249.0/27DHCP Range: 10.34.249.17-10.34.249.29

API VIP 10.34.249.15

Apps VIP: 10.34.249.16

I created wildcard dns records in DNSQMasq

cluster name ocp01

zone core.digital

DNSMasq Records:

address=/api.ocp01.core.digital/10.34.249.15

address=/.apps.ocp01.core.digital/10.34.249.16

VMs receive DHCP addresses,e.g. Boostrap VM has 10.34.249.29 address and 10.88.0.1 address.

Other nodes show GET Errors in consoles: GET https://10.34.249.15/...

When rebooting the boostrap node it goes to infinite wait fot the API VIP too.

UPD: Here is the cluster metadata:

I think you are missing some DNS records for your local environment (apt-int.ocp01.core.digital).

Here are DNS requirements you can check for some extra troubleshooting: https://docs.openshift.com/container-platform/4.13/installing/installing_platform_agnostic/installin...

Might also be worth checking all the firewalls and external loadbalancer config: https://docs.openshift.com/container-platform/4.13/installing/installing_platform_agnostic/installin...
