Issue/Introduction

 

Preparation of environment for DX OI 20.2.

In process of running validation of the environment and executing the command: ./install.sh -u=xxxxxxx -p=xxxxxx --validate

The checks run fine until:

[nginx-version] [ OK ] Nginx Ingress Controller version has been verified successfully
Specify the wildcard DNS [##.##.##.##.nip.io]: adminui.<subdomain>
[router-host-validate] [ ERROR ] Failed to resolve adminui.<subdomain> to IP.

However ping succeeds due to wildcard DNS configuration

]# ping adminui.<subdomain>
PING oi-master (##.##.##.##) 56(84) bytes of data.
64 bytes from oi-master (##.##.##.##): icmp_seq=1 ttl=64 time=0.051 ms
64 bytes from oi-master (##.##.##.##): icmp_seq=2 ttl=64 time=0.032 ms


The docs state:

"Enter the wildcard DNS of the node running the Ingress Controller (Kubernetes), Router (OpenShift), or the load balancer.

Validation:

Installer verifies if this host is reachable by pinging this host."
