Description of problem:

If FQDN provided by user not reachable the installer stop and not continuing asking more questions regarding the environment.


Today:
-------
$ ./bin/openshift-install create cluster --log-level=debug
? Platform ovirt
? oVirt API endpoint URL https://abcd.yzt
? Is the oVirt CA trusted locally? [? for help] (Y/n) 


Expected results:
----------------------
$ ./bin/openshift-install create cluster --log-level=debug
? Platform ovirt
? oVirt API endpoint URL https://abcd.yzt
DEBUG Checking URL Response: https://abcd.yzt      
FATAL Get "https://abcd.yzt": dial tcp: lookup abcd.yzt on 127.0.0.1:53: no such host

Attempted verification with: openshift-install-linux-4.6.0-0.nightly-2020-06-11-041445

Failed verification:
[root@ocp-qe-1 secondary]# ./openshift-install create install-config
? SSH Public Key /root/.ssh/id_rsa.pub
? Platform ovirt
? Engine FQDN[:PORT] ocp-qe-1.qa.lab.tlv.redhat.com
? Engine username admin@internal
FATAL failed to fetch Install Config: failed to fetch dependency of "Install Config": failed to fetch dependency of "Base Domain": failed to generate asset "Platform": you must pass a pointer as the target of a Write operation 

The same happens if I add port after the FQDN. Also, it seems as thought the PR referenced in this BZ was never merged. Could you please provide the actual PR?

Comment 3 Douglas Schilling Landgraf 2020-06-11 13:19:35 UTC

Thanks Jan. I was able to reproduce this as well, added the "Depends on" bug.

Comment 6 Jan Zmeskal 2020-06-19 08:17:54 UTC

Verified with: openshift-install-linux-4.6.0-0.nightly-2020-06-19-020835

Installer only proceeds when it gets FQDN/port combination that can be resolved. So the original intent of this BZ has been fulfilled. However, I ran into two cases, where this causes a little strange user experience and reported them here:
Bug 1848885 - OCPRHV-205: Exit installation once we receive 404 when trying to contact engine 
Bug 1848901 - OCPRHV-206: When trying to resolve engine FQDN, let's try to strip it from both ends
