Conducting the entire setup inside a virtual machine on a single bare metal server, we ensure no internet access is required. This comprehensive guide covers prerequisites including mirror registry, DNS setup, static IP configurations, pull secrets, and creating the ISO image. By the end of this video, you will have a fully functional, isolated OpenShift cluster suitable for enterprise, telecom, or defense applications. We also briefly touch on the importance of DNS forwarding and reverse lookup entries for cluster administration, certification, network validation, and future upgrades. Stay tuned for our next video where we will install operators in this disconnected environment using a previously created mirrored catalog. 00:00 Introduction to Disconnected OpenShift Setup 01:04 Prerequisites and Initial Setup 03:14 Configuring DNS and Network Settings 06:52 Downloading and Preparing OpenShift Install Tools 09:42 Creating Configuration Files 18:22 Generating and Using the Agent ISO 21:11 Simulating Bare Metal Installation 25:49 Monitoring Installation Progress 28:37 Finalizing the Installation 30:21 Conclusion and Next Steps
