This typically doesn’t present a problem for most customers, but select companies disallow use of Route 53 in favor of their own managed DNS (e.g. Infoblox). Unfortunately this limitation forces most customers to pursue a UPI (User Provisioned Infrastructure) deployment, which may (read: should) require custom terraform/ansible automation to standup all other prerequisities such as subnets, security groups, load balancers, EC2 instances, S3 buckets, etc. https://liveaverage.com/blog/practical-openshift-4-installation-troubleshooting/ Thu, 04 Feb 2021 00:00:00 +0000 https://liveaverage.com/blog/practical-openshift-4-installation-troubleshooting/ There’s a lot of great documentation on running, administering, consuming, and troubleshooting OpenShift 4, but the installation process is still a bit vague for some admins, and even more obscure if failures are encountered. I recently stepped through general installation troubleshooting for a failed OpenShift 4.6.8 deployment which hit this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1895024 - The core issue relates to low entropy on my VMs, but this bug was repeatable and offered a great exercise to share troubleshooting/diagnostic steps.
